New Blog at Wordpress

This post is to inform the small readership I have here, as well as the occasional visitor from the spurts of traffic I get from time to time, that my writings have relocated to a new Wordpress blog, where I will be posting from now on.

Here's the link: Skeptical Inquests: A Blog by Nathan Dickey

My plan for this new blog is to provide content that is much more blog-reader-friendly. This means posts that are much shorter and to the point. Occasionally there will probably be long posts, but not consistently. Blog readers, after all, don't want to read long essays when they click on new posts in their subscription feeds. This site has served my purpose of being a place for me to keep all the essays I've written in one place, but other sites serve that need better. My favorite is Academia.edu, and I encourage followers who are interested in longer treatments of the various subjects I've studied to broswe through my profile there. Thanks for reading, and I do hope you'll subscribe to my new Wordpress blog.

Refuting Quantum Spirituality

It is impossible for anyone to dispel his fear over the most important matters, if he does not know what is the nature of the universe but instead suspects something that happens in myth. Therefore, it is impossible to obtain unmitigated pleasure without natural science.
~ Epicurus

[T]here are idols which have immigrated into men’s minds from the various dogmas of philosophies, and also from wrong laws of demonstration. These I call idols of the theater, because in my judgment all the received systems are but so many stage plays, representing worlds of their own creation after an unreal and scenic fashion. Nor is it only of the systems now in vogue or only of the ancient sects and philosophies that I speak; for many more plays of the same kind may yet be composed and in like artificial manner set forth, seeing that the most widely different errors have causes which are for the most part alike.
~ Sir Francis Bacon, New Organon (1620)

Dance this world away

Introduction

People believe in and worship many kinds of gods. In the West, the god most commonly worshipped is the Judeo-Christian-Islamic deity. This god is said to participate in the universe in a very active way, being responsible for everything that happens in the universe and listening to every thought of every intelligent creature simultaneously. While there may be lesser gods who fit this basic description, for convenience we can refer to this model of deity as the “Abrahamic God.” This is a being that surely would be detectable by human observation – and should have been detected long before now – if he existed in reality. The fact that the Abrahamic God has never been detected allows us to conclude beyond a reasonable doubt that such a god does not exist [1].

But the Abrahamic God is just one particular kind of god among many others that have been and continue to be postulated. In this essay I undertake to tackle a type of spirituality which has become quite prevalent in Western culture today. I refer to what some have termed “quantum spirituality,” a body of belief which asserts that a separate reality lies beyond the material world revealed by science. Ironically, believers in this variety of otherworldliness have claimed a connection between their spirituality and quantum mechanics. As I will show in this essay, a scientific examination of the quantum spiritualists’ claims do not hold up against what professional physicists know about quantum mechanics through observation and experiment.

One approach to supernaturalism prevalent among many professional theologians and theistic scientists today is a “quantum theology” which conceives of a non-interventionist higher power. According to this model, the higher power does not violate natural law and therefore never performs any miracles [2]. Quantum theology differs from quantum spirituality in two respects. First, unlike its spiritualistic counterpart, science-based theology is a trend that has largely been confined to professional circles and has made little to no impact on the general public. Second, whereas quantum theology represents an effort on the part of theologians to reconcile their theological beliefs with the findings of modern physics, quantum spirituality seeks to redefine the findings of modern physics, to warp quantum mechanics into something it is not. For the science-savvy theologians, science is something their religious systems must answer to. For the quantum spiritualists, science must be made to conform to their mystical beliefs about the fundamental nature of life, the universe and everything.

The Pop Culture New Age Craze

The miracle-friendly and personalized New Age spiritualism, which made a significant impact on various Western countercultures of the 1960s and 1970s, has not come close to dying down in popularity and mass appeal in modern popular culture. This is evidenced by the reception of two very successful documentary films that appeared in the last decade, following in the tradition of earlier spiritualism-and-science films that have been well-received by the public, such as Bernt Amadeus Capra’s 1990 film Mindwalk. The first of these more recent offerings is 2004’s What the Bleep Do We Know!? [3] This modestly funded independent film grossed $10 million, not counting its several spin-off products. Even more successful was the 2006 documentary film The Secret [4]. The accompanying book by Rhonda Byrne [5] maintained the top spot on the New York Times Best Seller list for nearly 150 consecutive weeks.

What the Bleep Do We Know!? and The Secret are both careful in avoiding any suggestion that a personal god exists, but are not so careful in remaining scientifically respectable. Both films suggest that there exists a greater power of some kind, a cosmic consciousness into which we humans are capable of tuning with our minds, and the authors of both films look to the science of quantum mechanics to justify their claims. Because there is such a great deal of apparent mysteriousness in quantum mechanics, arising from the spooky phenomenon of the observer and the observed appearing to become strongly intertwined, the argument is made that “we create our own reality” just by thinking.

In an effort to lend scientific credibility to their claims, the makers of What the Bleep Do We Know!? bring in PhD scientists such as Amit Goswami and Fred Alan Wolf, among others, for on-screen interviews. Goswami, now retired from his professorship at University of Oregon where he taught physics for thirty-two years, received a PhD in theoretical nuclear physics from Calcutta University in 1964. Wolf received a PhD in theoretical physics from the University of California at Los Angeles (UCLA) in 1963. Both Goswami and Wolf are well-educated physicists, so whether they are deliberately misrepresenting the findings of quantum mechanics to promote their personal beliefs (and make a lot of money) or whether they are actually ignorant of some details of quantum mechanics is a matter of debate.

There are various data points one can use to support either possibility. On the more cynical side, it may be pointed out that the three directors of What the Bleep Do We Know!? are all students of mystic and channeler J.Z. Knight, who in the film is featured channeling a 35,000 year-old being called Ramtha. This has led some reviewers to criticize the film as a promotional recruitment tool for Ramtha’s School of Enlightenment, an institution founded and operated by Knight. The directors deny this charge, insisting that the film is their own independent work. Of course, whether Bleep was intended as a recruitment film or not has no bearing on the truth or falsity of the film’s claims and thesis, which must be evaluated on their own terms. Still, it does stand as an eyebrow-raising bit of information.

On the other hand, Amit Goswami strikes me as one who sincerely believes what he says in the film (Fred Alan Wolf just strikes me as a bit insane, a “mad scientist” of sorts). Many of his ideas come from Indian mysticism, and Hindus tend to believe strongly in their religion. But while Goswami believes he has found a connection between Indian mysticism and physics, the arguments he uses to support his conceptual bridge do not withstand the level of scientific scrutiny Goswami must have at least some currency in, given his credentials. In his book The Self-Aware Universe, Goswami makes many insupportable statements like the following:

As the real experiencer (the nonlocal consciousness) I operate from outside the system – transcending my brain-mind that is localized in space-time – from behind the veil of the tangled hierarchy of my brain-mind’s systems. My separateness – my ego – emerges only as the apparent agency for the free will of this cosmic “I,” obscuring the discontinuity in space-time that the collapse of the quantum brain-mind state represents [6].
No credentialed physicist who has not first put the cart of personal belief before the horse of scientific scrutiny could with a straight face treat as uncontroversial the prospect of consciousness operating nonlocally. The term nonlocal (also called superluminal) has a special meaning in physics; it denotes the motion of bodies or transfer of information between two points, which are unconnected by any common reference frame, at speeds faster than the speed of light. This is forbidden by Einstein’s special theory of relativity and by conservation of energy, both of which have been confirmed by numerous tests to a high degree of accuracy [7]. Quantum mechanics neither requires nor implies the existence of nonlocal or superluminal phenomena. When Goswami later states in his book that “heaven” can refer to this life and that it is “not a place but an experience of living in quantum nonlocality” [8], he abandons the horse altogether and flies off on a magic carpet outside the realm of scientific coherence.

However, Goswami’s scientific work is legitimate enough to make him acknowledge the indispensability of observational testing in science, to which he appeals when he claims that extrasensory perception (ESP) experiments “have been carried out in many different laboratories, and positive results are claimed with both psychic and nonpsychic subjects” [9]. And in addition to admitting that “telepathy has not yet been recognized as a scientifically plausible discovery,” he even understands the skeptical reasoning justifying the wariness of the majority of scientists toward acceptance of psychic phenomena as real: “[ESP] does not seem to involve any local signals to our sense organs and hence is forbidden by material realism” [10]. Thus, rather than necessarily being disingenuous and deliberately misrepresenting quantum mechanics, Goswami’s pseudoscience may be a simple case of compartmentalization, a cognitive dissonance between his beliefs and his scientific work.

For what it’s worth (which is not much) The Secret is much more pronounced and straightforward in its assertions in comparison to the vague claims of What the Bleep Do We Know!? But to the extent that the assertions of the former are more concrete, they are the more egregious [11]. Like Bleep, the film features interviews by PhD physicists and other scientists who lend their enthusiastic support to ideas pushed by the film and book. These include Fred Alan Wolf (introduced above) and John Hagelin, both of whom also appeared in Bleep. Hagelin, a Harvard-trained physicist and three-time presidential candidate on the Natural Law Party ticket, has distinguished himself as a prominent leader in the New Age movement. This is what Wolf and Hagelin has to say about the Secret:

Dr. Fred Alan Wolf: I’m not talking to you from the point of view of wishful thinking or imaginary craziness. I’m talking to you from a deeper, basic understanding. Quantum physics really begins to point to this discovery [of the Secret]. It says that you can’t have a Universe without mind entering into it, and that the mind is actually shaping the very thing that is being perceived [12].

Dr. John Hagelin: Quantum mechanics confirms it [the Secret]. Quantum cosmology confirms it. That the Universe essentially emerges from thought and all of this matter around us is just precipitated thought. Ultimately we are the source of the Universe, and when we understand that power directly by experience, we can start to exercise our authority and begin to achieve more and more. Create anything. Know anything from within the field of our own consciousness, which ultimately is Universal consciousness that runs the Universe. . . . So we are the creators, not only of our own destiny, but ultimately we are the creators of Universal destiny. We are the creators of the Universe [13].

Like the PhD scientists who appear in Bleep, the PhD-clad mystics in The Secret have nothing in the way of evidence to support their claims, only assertions. And one does not need to be well-read in physics to see this. For example, for all his talk about creating anything we desire and precipitating our thoughts into reality, Hagelin’s three runs for the presidency in the eight years between 1992 and 2000 not only failed, but he amassed a total of only 236,586 votes [14].

So what is this “Secret” Rhonda Byrne claims to have discovered? It is nothing more than what has been said in the New Age movement for over thirty years: through the law of attraction, we humans create our own reality. This theme is repeated over and over again in the film and in the book (in fact, if Byrne had been more studious in avoiding repetition, her book could easily have been written in ten pages or even less). The Secret turns this familiar New Age philosophy into a self-help tool purporting to demonstrate that anybody can be whoever he or she wants to be. The secret to being rich, beautiful and healthy is simple:

If you can think about what you want in your mind, and make that your dominant thought, you will bring it into your life [15].
In other words, you only have to want wealth, beauty and health. Earnest desire is all that is required on your part; you just have to want whatever it is you are after, and the Secret is guaranteed to work for you. You must think positive thoughts at all times, and whatever you want to happen in your life will come about.

Of course, not everybody is rich, beautiful and healthy. How are we to account for this fact? The explanation offered by The Secret is that people who do not have what they want have not been thinking the right thoughts. They were thinking too negatively. As Byrne explains,

The only reason why people do not have what they want is because they are thinking more about what they don’t want than what they do want. Listen to your thoughts, and listen to the words you are saying. The law is absolute and there are no mistakes [16].
Byrne is not expressing an original epiphany. The same ideas she claims to be revealing to the general public for the first time have been spread by adherents of New Age belief for the past half century. A more general overview of the pop culture New Age craze is in order.

The modern New Age movement began making an impact in Western culture in the early 1960s. An Indian yogi who called himself Maharishi Mahesh Yogi contributed much to the popularization of Eastern mysticism in the West with his new meditation technique called transcendental meditation (TM) [17]. Maharishi, who was trained as a physicist, devoted much of his career to trying to make connections between ancient Eastern beliefs and modern quantum physics. Around the same time he was travelling the United States and Great Britain teaching his synthetic philosophy of ancient mysticism and modern physics, a young Austrian-born American physicist named Fritjof Capra brought this harmonization to an even larger U.S. audience. In his 1975 bestseller The Tao of Physics, still available in the science section of most bookstores, Capra claimed to show that “there is an essential harmony between the spirit of Eastern wisdom and Western science . . . that modern physics goes far beyond technology, that the way – or Tao – of physics can be a path with a heart, a way to spiritual knowledge and self-realization” [18]. Fritjof Capra is the brother of the above-mentioned writer and director Bernt Amadeus Capra, whose film Mindwalk was co-written by Fritjof.

Several of the prominent names in quantum spirituality on the contemporary scene have been misusing modern physics to support New Age beliefs for decades, having started their careers close on the heels of Maharishi’s TM movement and Fritjof Capra’s work. Perhaps most prominent of all today is Deepak Chopra. His bestselling books include such titles as Quantum Healing (1989) [19] and Ageless Body, Timeless Mind: The Quantum Alternative to Growing Old (1993) [20]. These and many of his other books rely heavily on the argument that quantum mechanics provides a way for us to create our own reality. In Chopra’s own words, “There is no objective world independent of the observer. . . . [You] use your senses to congeal the [quantum] soup into the solid three-dimensional world” [21].

Not surprisingly, spiritualistic philosophy that claims a connection to quantum physics has a huge presence on the World Wide Web. To take just one subject, an online search for “quantum healing,” the concept first popularized by Chopra over twenty years ago, will turn up hundreds of thousands of hits on the low end of the scale for web sites and blogs preaching the philosophy that our mind is collectively tuned into a reality separate from the material universe (my own search as of this writing turned up 2,260,000 hits).

The Spooky Quantum

The claimed scientific basis for the validity of Eastern mysticism stems from the mysteriousness or “spookiness” supposedly implied by several phenomena observed quantum mechanics. Since an in-depth discussion of all these phenomena would require a book-length treatment, I will confine myself in this essay to just one, with which the purveyors of quantum spirituality are especially enamored: the so-called “wave/particle duality.”

After physicists finish their quantum-level measurements, they find that waves are not the only form in which light appears. The wave phenomenon of light has been well understood since 1800, when Thomas Young’s two-slit interference experiment with light demonstrated that light behaves like waves. Long before Young’s experiment, Isaac Newton proposed that light was made up of particles, which he called “corpuscles.” Throughout the nineteenth century, the corpuscular particle model of light was largely abandoned in favor of the theory that light was fundamentally wavelike.

With the rise of quantum mechanics early in the twentieth century, evidence that light was made up of tiny quanta of energy began to accumulate. The same duality observed in these energy particles, dubbed photons, was observed to be at play in electrons and most other particles: sometimes they behave like particles and sometimes they behave like waves. The “wave/particle duality” therefore refers to the “spooky” observation that whether a measured body behaves like a wave or a particle depends on what is being measured for. When a wavelike property of an object is being measured, the object behaves like a wave. When the position of any particle within the same object is measured, it behaves particle-like. Fritjof Capra sees special significance in this apparent duality for New Age practitioners, even going so far as to equate it with the difference between the concepts of existence and non-existence:

The reality of the atomic physicist, like the reality of the Eastern mystic, transcends the narrow framework of opposite concepts . . . Like the atomic physicists, the Eastern mystics deal with a reality which lies beyond existence and non-existence, and they frequently emphasize this important fact . . . Faced with a reality which lies beyond opposite concepts, physicists and mystics have to adopt a special way of thinking, where the mind is not fixed in the rigid framework of classical logic, but keeps moving and changing its viewpoint [22].
The illusion created by this apparent duality is that an observer can decide for herself what form reality will take by the very act of deciding what property to measure in any given object. That object could be light relayed from a distant galaxy 13 billion years away, when the light first left its source. The implication is that our mind affects the reality of objects, not only in the present moment but in all moments in time and space throughout the universe, past and future. Amit Goswami writes, “The paradox of wave-particle duality – that quantum mechanics have both wave and particle aspects – needs a resolution, which means interpretation and philosophy” [23]. He proceeds to cite the wave/particle duality as one of the features of quantum mechanics which points to another kind of reality transcending the material one. This radical interpretation of the wave/particle duality is typical of how New Age believers try to use science to support their claim that our minds pervade the entirety of the universe and are intimately tuned into it.

Ghostbusting the Quantum World

When a modern-day experimenter performs Young’s light experiment with advanced equipment that is sensitive enough to detect each individual particle of light, or photon, particles will always register on the measuring equipment. When the experiment is set up to measure a given wave property, the experimenter will not see the individual particles. This does not imply a duality between particles and waves. Contrary to the quantum spiritualists’ claims, it implies the very opposite: there is no wave/particle duality.

Consider an experiment in which we send photons from a point source through two slits in a screen (this is the standard experiment used by physicists for measuring the wave effects of particles). On the other side of the screen, an interference pattern of dark and light bands will be seen on the wall where the light strikes after passing through the two slits. If the equipment we are using is sufficiently sensitive, we will see each individual hit on the wall. The first few hits will appear as a highly random and localized pattern. But as the number of hits increases, an interference pattern will form. Eventually the pattern will look just the same as it would if we had simply taken a photograph picture of light in its familiar double-slit wave form. In short, the wave effect is all in the statistics [24].

Larger, classical bodies of everyday experience also act in a manner approximating a wave, a behavior unnoticeable to us on large scales but still determined by the average behavior of huge collections of individual particles which, with the aid of positive feedback, aggregately constitute familiar matter. This behavior of matter is closely connected to the Heisenberg Uncertainty Principle, introduced by Werner Heisenberg in 1927. The “fuzziness” ultimately associated with all material bodies is a consequence of our inability to locate particles while simultaneously measuring their momentum. It is not a consequence of a permeable duality controllable by human minds. Far from being in control of what form reality takes in our observations, physicists often find that their only recourse is to describe objects in terms of a wave rather than localized particles, a pulse rather than a point. Wavelength measurements are what inform us on the extent to which particles can bend around corners, for example. The reason we can hear around corners is because sound is a wave phenomenon (not everything is made up of particles, after all), and waves can only occur in a medium such as air or water as vibrations. The wavelength of sound is long enough to bend around corners, and an easy way to understand this is to picture wavelengths as series of water waves rolling in and bending around a rock near shore. As we all know, water waves can also move around corners in the same way sound does.

Light exhibits the same behavior on large scales, although this is not as obvious. In fact, one of the reasons Newton rejected the wave theory of light, which had been proposed by his contemporary Christiaan Huygens, was that he wrongly believed light could not bend around corners. Although Newton was a great experimentalist, he simply did not look closely enough in this case to see that light does indeed bend. This bending can be seen by holding a card pierced with a small pinhole up to a light (either the sun or an artificial light). If the pinhole is sharp enough, light can be seen diffusing through it. While this phenomenon is often misleadingly referred to as a feature of the “wave property” of light, it is nothing more than the uncertainty principle in action. To send a particle through the pinhole in the card is to localize the particle, and the uncertainty principle states that when an object is localized too much, its momentum becomes uncertain. This uncertainty causes particles (in this case photons) to change direction just slightly as they pass through the pinhole. The fact that we rarely see light bend is simply a consequence of the fact that the individual photons cannot be measured to any appreciably high degree of accuracy. The common-sense rule that “light travels in straight lines” is a crude approximation of large-scale phenomena that does not apply to quantum scales.

When we measure for so-called “wave properties,” what we are seeing is nothing more than the statistical distribution of all the particles being observed. This is how quantum mechanics describes the wave function, which turns out to be just as fictional as the wave/particle duality. The wave function is not a property of any particle or group of particles. It only describes the probability for finding a particle at a particular position in space. Retired particle physicist Victor Stenger, a skeptic of mystical and theistic claims who has written extensively on the spiritualists’ misuse of quantum mechanics, explains why treating the wave function as real leads to certain impossible conclusions:

If you insist on interpreting the wave function as a “real” physical entity such as a water wave, then it moves faster than the speed of light, indeed, infinite speed, violating a basic tenet of Einstein’s special theory [of relativity]. However, if we accept that the wave is just an abstract mathematical entity physicists use to compute the probability for finding a particle at a particular position in space, then there is nothing spooky about it. Abstract things can move as fast as their inventors wish [25].
Stenger goes on to describe a thought-experiment illustrating the non-reality of wave function collapse. Suppose you are living on a planet in the Alpha Centauri star system four light-years away from Earth. A friend of yours on Earth enters your name in a lottery, and you win the million-dollar prize. Your new wealth is analogous to the wave function. At the moment you win, your probability of winning collapses instantaneously and your wealth increases by one million dollars. However, there you are four light-years away in Alpha Centauri, unaware that you have won the Earth lottery. More importantly for practical matters, your bank in Alpha Centauri is unaware of your wealth, because any news-bearing signal sent to you and to your Alpha Centauri bank from Earth at light-speed will take four long years to arrive. You cannot spend the million dollars until those four years have elapsed [26].

The wave function works the same way. It is simply an abstract mathematical description of probability terms that can collapse as much as it needs to – at every point in the universe and instantaneously – without violating special relativity. Real physical entities cannot do this, but mathematical abstractions can.

Despite the strangeness of quantum mechanics and its assault on common sense, it is built on a very solid and precise mathematical basis. I will let the famed physicist Richard Feynman put this achieved level of precision in perspective:

If you were to measure the distance from Los Angeles to New York to this accuracy, it would be exact to the thickness of a human hair. That’s how delicately quantum electrodynamics has, in the past fifty years [since 1930], been checked – both theoretically and experimentally [27].
The earlier quantum mechanics of Niels Bohr, who introduced the quantum theory of the atom in 1913, was very crude in comparison to Heisenberg’s matrix mechanics and Erwin Schrödinger’s wave mechanics, two mathematical theories developed in 1925 and 1926 respectively. In 1930, Paul Dirac unified these two versions of mathematical quantum theory into a formalism he called transformation theory. This unified theory is more mathematically advanced than Schrödinger’s version of quantum mechanics, which is the least sophisticated of all the formalisms as well as the most familiar version, studied by physics students at the undergraduate level and written about most in popular physics books. Dirac’s sophisticated method, first introduced in his classic 1930 textbook Principles of Quantum Mechanics, continues to this day to be the way most professional physicists do quantum mechanics. Thus, it is very telling that the term “wave function” appears only once in Dirac’s book, in a short footnote where it is treated dismissively:
The reason for this name [wave function] is that in the early days of quantum mechanics all the examples of these functions were of the form of waves. The name is not a descriptive one from the point of view of the modern general theory [28].
In other words, the mathematics involved in quantum mechanics sometimes resembles that of a wave, but this is nothing more than a residual artifice, a mathematical coincidence. There are no actual waves, only particles. The non-dualistic nature of light was helpfully stressed by Richard Feynman in the first of a series of lectures on quantum electrodynamics given thirty years ago to high school students:
I want to emphasize that light comes in this form – particles. It is very important to know that light behaves like particles, especially for those of you who have gone to school, where you were probably told something about light behaving like waves. I’m telling you the way it does behave – like particles [29].
Some theoretical physicists invoke quantum field theory as a possible counter-argument to this particle picture of reality, saying that fields are more fundamental than particles. In this view, particles are just manifestations of fields. But this is an ontological view that cannot easily be tested for experimentally. The debate over particles and fields among physicists reduces to an argument over preferences. More to the point, it is a debate about reality that often takes an uncomfortable metaphysical turn. All anyone can know about reality is through experiment. Being a non-scientist myself, I prefer the consensus particle model over the field model in the theories physicists are conversant in. For one thing, it is far easier to visualize and simpler to construct, and thus nicely consistent with Occam’s razor. This is also the view of many great physicists, on whose expertise I rely as a non-scientist.

Physical Theory and Philosophical Reality

What I have been describing in the preceding section is all part of standard quantum mechanics. It is a standard picture that is unappealing to those who try to make connections between quantum mechanics and New Age spirituality, because standard quantum mechanics does not support New Age hypotheses (and in fact militates quite strongly against it). Instead, people erroneously read New Age spiritualism into quantum mechanics in highly misleading popular expositions which take advantage of people’s misunderstandings of science.

In a famous remark touching on the difficulty of grasping physics at the quantum level, Richard Feynman once remarked, “I think I can safely say that nobody understands quantum mechanics” [30]. I am going to boldly differ with Feynman on this point and say that thousands of people, including even some non-physicists, understand quantum mechanics reasonably well (His admirable and characteristic modesty notwithstanding, Feynman himself understood the science very well!). However, Feynman’s remark does apply very well to those who write about quantum mechanics in abstract philosophical terms, especially those who have no background or expertise in physics. Like any other area of knowledge, scientific or otherwise, it is important that one really understands the subject before talking or writing about it. This is a criterion many gurus of quantum spiritualism do not meet. Much of the popular literature claiming parallels between New Age belief and quantum mechanics are shining examples of a sort of “intellectual anarchy” that is trendy in today’s culture. As Milton Rothman writes,

Everyday anarchy romps through the current intellectual scene: an engineer [young-earth creationist Henry Morris] writes books on evolution, a science fiction writer becomes a psychotherapy guru and founds a new religion [L. Ron Hubbard, founder of the Scientology pseudoscience], a psychoanalyst rewrites the laws of celestial mechanics [Immanuel Velikovsky of Worlds in Collision infamy], theologians give pronouncements on physics, physicists write books on theology, and legislators write laws defining life [31].
To this we can add the spectacle of a physician writing books on quantum mechanics. Deepak Chopra has no understanding or background in quantum mechanics, a subject on which he lectures and writes a great deal.

The looseness with which quantum mechanics is treated by armchair physicists who have an ideological bone to pick is one of the justified reasons for the prevailing attitude of dislike toward philosophy currently seen among those in the physics community (this is mostly the case with experimental and practical physicists, but is true even of many theoretical physicists as well). This was not always the case; the current aversion to philosophy among the physics community started in earnest with the post-World War II physicists. Prior to the war, the great physicists of the twentieth century – among them Bohr, Heisenberg and Schrödinger – were very interested in philosophical interpretations of quantum mechanics and of the other kinds of physics they studied. This interest was especially strong in Einstein, who philosophized a great deal. This early interest in philosophy among physicists is not surprising or anomalous for, as Rothman points out, “modern philosophy of science is to a great extent the philosophy of quantum theory. . . . quantum theory, in its role as the fundamental theory of matter and energy, makes a number of statements which contradict our ‘commonsense’ notions of nature. Philosophical problems arise when we try to make scientific sense out of these contradictions” [32].

Notwithstanding the conduciveness of quantum theory to philosophical “hashing out,” the group that came into power in the physics community following World War II (led for the most part by Richard Feynman, Steven Weinberg and other household names) drastically changed the attitudes of most physicists toward philosophy. They emphasized that all we can really know is what we measure and observe, all the rest being nothing but empty and meaningless talk. If we can make accurate measurements and then describe those accurate measurements with theories, it does not matter what the theory really means. Arguing about the underlying meaning of theories is a waste of breath. The only relevant issue is whether the theory actually works. If it does, then it is “true enough.” If it does not work, it is useless and we toss it out on our way back to the starting board. That is all we really we need to understand, because everything we use our scientific theories for is based on observed objects, not on ontological meaning.

For example, theories are useful for building practical things like electronic circuits. Maxwell’s equations of electricity allow us to construct electric magnetic fields emitted by antennae. Do those fields actually exist? As far as the pragmatic physicist is concerned, they do exist in the sense that they have an observable effect. But no one has ever actually seen an electric field or a magnetic field. All we can see are particles such as electrons being accelerated by the presence of other electrons or other charged particles. That activity is what physicists measure and observe. The description of that measured observation is the theory, in this case a model of fields. If the theory works, then it is good enough and physicists do not lose sleep over questions of whether there is a one-to-one correspondence between theories and ultimate reality.

In his popular 1988 book A Brief History of Time (a book more often purchased and quoted than read and understood), world-renowned physicist Stephen Hawking defines the true value of a theory as follows:

I shall take the simple-minded view that a theory is just a model of the universe, or a restricted part of it, and a set of rules that relate quantities in the model to observations that we make. It exists only in our minds and does not have any other reality (whatever that might mean). A theory is a good theory if it satisfies two requirements: It must accurately describe a large class of observations on the basis of a model that contains only a few arbitrary elements, and it must make definite predictions about the results of future observations [33].
This description and account of scientific theory represents, in my view, a legitimate philosophical approach to determining the truth value of any proposition in science. Scientists have nothing to fear from philosophy, so long as the science is correctly done first. New Age gurus who misuse and quantum mechanics and cosmology to make a scientific-sounding case for their preconceived spiritualistic beliefs have not satisfied the criteria of a good theory as described by Hawking and most other scientists and philosophers of science. Their strained harmonizations of science and spirituality fail to explain anything we observe.

Indeed, the “job description” of every scientist can be summed up in the single word explain. This is done through careful measurement and observation, and the “laws of physics” are crafted by this explanatory process. In other words, they are inventions of human observers. More and more philosophers of science are beginning to take this view. In the words of philosopher David Armstrong,

There is one truly eccentric view. . . . This is the view that, although there are regularities in the world, there are no laws of nature [34].
This view was independently arrived at by Victor Stenger, the experimental particle physicist cited above, who argues in his important book The Comprehensible Cosmos that there are no laws of physics (if this is not a confirmation that hard science and philosophy can meaningfully touch bases and find consonance with each other, I don’t know what is!). What we misleadingly refer to as the “laws of physics” are simply restrictions physicists place upon themselves. Far from implying that our descriptions of the universe are arbitrary and that we “create our own reality through observation,” this means that scientists must write down their theories and models in such a way that they fit the observed data. Moreover, scientific theories and models must be formulated to be objective; they cannot depend on the subjective point of view of any one observer. Stenger demonstrates mathematically in his book that one can derive most of the physics we know from just one simple assumption, which Stenger calls point-of-view invariance: “The models of physics cannot depend on any particular point of view” [35].

Stenger did not invent the principle of point-of-view invariance. It was originated by a German mathematician named Emmy Noether, who in 1918 proved a theorem now known as Noether’s Theorem [36]. The theorem states that any theory involving space and time, if formulated in such a way that it does not depend on any particular moment in time when the observer starts her clock (meaning the theory is formulated such that it holds as good now as it did at any time in past history), then that theory will by definition contain a quantity that is conserved, namely energy. The theorem applies to position in space as well; if a theory does not depend on any special position in space, conservation of linear momentum necessarily follows. Finally, if no direction in space is singled out as special in the theory, conservation of angular momentum will automatically be conserved in the equations.

Practically all of classical physics follows from just these three conservation laws (the only exceptions are gravity and some electrical forces, but these do not require much more information to be accounted for). All our knowledge of classical physics, acquired from Newton to the twentieth century, follow from conservation of energy, conservation of linear momentum and conservation of angular momentum, and these conservation principles follow in turn from point-of-view invariance. The implications of Noether’s discovery is profound: it means that as far as we know there is no external force – spiritual or otherwise – governing the behavior of matter from above. This also means that the “laws” of nature do not necessarily describe ultimate reality.

Again, this does not imply there is no underlying objective reality independent of our subjective experience, as the peddlers of New Age mysticism would have us believe. On the contrary, point-of-view invariance and Noether’s Theorem show that there must be an objective reality. As Stenger explains,

[Point-of-view invariance] comes simply from the apparent existence of an objective reality – independent of its detailed structure. Indeed the success of point-of-view invariance can be said to provide evidence for the existence of an objective reality. Our dreams are not point-of-view invariant. If the Universe were all in our heads, our models would not be point-of-view invariant. . . .

Point-of-view invariance is thus the mechanism by which we enforce objectivity. If we did not have an underlying objective reality, then we would not expect to be able to describe observations in a way that is independent of reference frames [37].

Even though we currently have no way of knowing what the “true” structure of reality looks like, the existence of an objective reality underlying and informing the imperfect but adequate models we use to describe observations is confirmed every moment of every day by numerous obvious (and some not-so-obvious) impositions of what Rothman calls “laws of denial” (which he compares and contrasts with “laws of permission”). “Choosing between the possible and the impossible is a task carried out by means of the laws of denial, which tie us firmly to reality even as imaginations soar unfettered through the universe” [38]. Contrary to the assertions of Rhonda Byrne and her doctrine of the Secret, not everything we may want to happen can happen. We cannot create our own reality, and the universe does not care what we want or desire. We cannot “dance this world away,” in the words of the song by Rick Springfield.

Note that Rothman uses the word “choosing” in his statement about distinguishing between the possible and the impossible. While it is true the laws of physics are human inventions, they must agree with the observed data to be considered valid. We cannot just “choose” to travel faster than the speed of light no matter how much we may desire to, for example [39]. The theories and models scientists find useful in making testable predictions that can be verified or falsified are anything but arbitrary. Science is not an exercise in postmodernism, which asserts that science is simply one cultural narrative among many and that all narratives are equally true. That is simply not the case in science, for which there is only one narrow set of “narratives” that work, namely the ones that agree with the data.

Einstein only ever postulated (not confirmed through proof, derivation or measurement) that the speed of light in a vacuum is a constant; that is, it is invariant, remaining the same from all points of view and reference frames. Thus, while it is true that there is no actual known mechanism dictating that light cannot travel faster than Einstein’s constant c, his theory has proven to be so successful in making sense of observations that in 1983, physicists worldwide redefined the standard meter in terms of a clock, not a meterstick: “the time light takes to travel between two points in a vacuum.” The second, defined by the cesium fountain atomic clock at the National Institutes of Standards and Technology (NIST) laboratory in Boulder, Colorado, is the only unit with which the physics community now defines time (for more information, see http://www.nist.gov/pml/div688/grp50/primary-frequency-standards.cfm). Consequently, the speed of light is now a constant by definition. One cannot coherently talk about changing the speed of light, because one would then be forced to also change the definition of distance from the current invention. This is not to say, of course, that light in a medium does not slow down, which we know it does. We are talking about the ideal case of light traveling in a perfect vacuum, not a medium. And that equals c by definition.

The Scientific Verdict on God (Part 4): The New Deism

The more we refine our understanding of God to make the concept plausible, the more it seems pointless~ Steven Weinberg [1]

In his bestselling 2006 book The God Delusion, Richard Dawkins quotes geneticist Jerry Coyne as saying that the real nature of the current conflict between religion and science goes far deeper than just the cultural battle between evolution and creationism:

It’s not just about evolution versus creationism. To scientists like Dawkins and Wilson [E.O. Wilson, the celebrated Harvard biologist], the real war is between rationalism and superstition. Science is but one form of rationalism, while religion is the most common form of superstition. Creationism is just a symptom of what they see as the greater enemy: religion. While religion can exist without creationism, creationism cannot exist without religion [2].
If theists want to use reason to argue for their position that a god exists, whatever model of god that may be, they have every right to do so. If they argue on the basis of ancient superstitions, on beliefs based on the myths of a primitive tribe that lived in the desert thousands of years ago and thought very highly of themselves and regarded themselves as special, then there is no point in arguing with them. If, on the other hand, we are going to debate on mutually-agreed grounds of rational argumentation – that is, if the theist agrees along with the atheist that they are going to make clear what their assumptions are and what their reasoning is for making those assumptions, then we should levy no objection to taking the time to debate with them. We atheists want just that kind of debate.

Incidentally, there are many theologians who do just this. Physicist and atheist Victor Stenger refers to this class of theists as the “Premise Keepers” in his 2003 book Has Science Found God? [3] This is a group with whom he sympathizes despite his disagreement with their conclusions. The premise keepers are theologians who fully accept and embrace the findings of modern science. They reject the approaches of people like William Dembski and Michael Behe and the flat-earth creationists before them, who want to denigrate science. But the premise keepers are theologians, after all. They cannot very well argue that God does not exist, because then they would find themselves out of a job. Therefore, they have to start with the assumption (the premise) that God exists and then attempt to make that proposition consistent with everything we know, not just in science but in all areas of knowledge that weigh in on the god question. And they have actually made a fairly impressive effort in this task by developing a highly abstract idea of god.

Their abstraction of god has led many of those who follow and agree with their books and articles to write highly critical reviews of the “new atheist” literature that has hit the publishing world like a storm in the past decade. A common accusation they make against the new atheists is that the latter group has not recognized what eminent scientist-theologians like John Polkinghorne or others like him have said. This is simply not the case; atheist writers have considered and written a fair amount about the science-savvy theologians, and I can direct any fan of the premise keepers to the relevant books and articles. However, in many other cases the abstract god of the theologians is not the kind of god being discussed in recent atheist literature. The theologians’ god, who may have created the universe and then allowed it to run on its own, just as in the Enlightenment model of the deist god, is not as interesting as the much more falsifiable personal god of theism who throughout history interacts and interferes with his creation on a moment-to-moment basis. The premise keepers posit a different god, one that essentially amounts to a modernized version of the old deism. Whereas the deism of the Enlightenment was an offshoot from the revolutionary Newtonian picture of the world as a clockwork mechanism, the new deism is an offshoot from developments of quantum mechanics early in the twentieth century.

Most educated theologians today fully realize that the God they espouse does not answer the prayers of the faithful. Most do not believe Jesus resurrected from the dead or that he was born of a virgin. They are fully aware that these stories and concepts are fictional, quaint mythological stories that may have served some purpose at one time in the past, as all myths seem to have done. Mythology once provided people with a way of understanding their life and the world in which they found themselves that was appropriate for their level of intellectual development.

Thus, when today’s educated theologians take to task common definitions of God – employed by us outspoken “new atheists” for use in hypothetical argumentation – they are not disagreeing with our observation that the personal God most people believe in does not answer prayers. They are disagreeing with the model of a God that does things like respond to prayers, raise people from the dead, and impregnate virgins with his holy spirit. They realize that the model of this active personal God is a testable hypothesis and one moreover that has failed the test in both science and philosophy. And theologians are notoriously averse to testable hypotheses. Rarely do we ever hear them positively define their god to let us know what they actually believe their god is and what he/she/it actually does. These are the theologians whose sole objection to Richard Dawkins’ The God Delusion is an insistence that the kind of deity Dawkins dismantles is not the god they believe in. But they rarely lay out what they actually do believe about god, only what they do not believe god is like.

Evolution Theology

There are several exceptions to this general rule, of course. For example, in the cultural conflict between Christianity and the science of biological evolution, large groups of moderate Christians – taking their cue from the Catholic Church in general – have come out in support of the theory of evolution. Incidentally, this is one of the reasons the majority of scientists are loathe to involve themselves in too great a conflict with these religious groups; they reason that they need their continued support in order to see evolution taught more often than it unfortunately is in most public schools.

The fact that many religious groups support evolution means that several scientifically-literate theologians must have some answer to the largest theological problem raised by evolution: the fact that the existence of humans is an accident of nature. As the late eminent paleontologist Stephen Jay Gould pointed out, if we were to wind back the “tape” of evolution and start the process up again from the beginning without changing any of the laws of chemistry, biology or physics, we would not see any of the same set of species we do today. Humanity would not again evolve, since humans are the product of innumerable accidents, chance events that occurred in the process of evolution [4]. The evolutionist John Maynard Smith reiterated Gould’s point in a review of the latter’s work:

If one was able to replay the whole evolution of animals, starting at the bottom of the Cambrian (and, to satisfy Laplace, moving one of the individual animals two feet to its left), there is no guarantee – indeed, no likelihood – that the result would be the same. There might be no conquest of the land, no emergence of mammals, certainly no human beings [5].
This means that humanity is not special. Yet the Christian religion, along with most other religions, has always placed humanity at the center of the universe. Christianity thus has no viable way of accounting for evolution and reconciling it with Christian doctrine.

How do theologians cope with this? Some, like physicist and Episcopalian priest William Pollard, suggest that God occasionally pokes his finger in at various points to bring about the emergence of human beings [6]. But this model is not consistent with evolution, which is a naturalistic process which operates by a well-established naturalistic mechanism. Pollard’s model is a form of intelligent design.

Other believers come up with a different theology more consistent with evolution as a naturalistic process. One approach is to basically revert to the god that Einstein famously objected to, namely the god who throws dice. Kenneth Miller, an evolutionary biologist and devout Catholic, suggests that God created the universe with a number of initial possible pathways and then played dice, letting his universe go to let its pathways obtain naturally according to chance, without interfering in any way after the toss. “Evolution is not rigged,” he writes, “and religious belief does not require one to postulate a God who fixes the game, bribes the referees, or tricks natural selection” [7]. This view is shared by physicist and theologian Ian Barbour, who writes, “Natural laws and chance may equally be instruments of God’s intentions. There can be purpose without an exact predetermined plan” [8]. One possible pathway (and the one that the universe obviously took) resulted in the evolution of humanity, but another possible pathway may have led to some other advanced creature. It was just an accident of chance that the path happened to result in the human species.

In any case, Miller and others with similar views believe that God’s purpose was served, and would have been regardless of what path the universe naturally followed after his roll of the cosmic dice:

Given evolution’s ability to adapt, to innovate, to test, and to experiment, sooner or later it would have given the Creator exactly what He was looking for – a creature who, like us, could know Him and love Him, could perceive the heavens and dream of the stars, a creature who would eventually discover the extraordinary process of evolution that filled His earth with so much life [9].
In other words, whatever path the universe took, whether it resulted in the emergence of humanity or in some other species, God’s only “intention” was to allow the dice to roll as they will. Whatever might have happened, they say, God’s purpose in throwing the dice in the first place is accomplished. As Miller puts it, “If another group of animals had evolved to self-awareness, if another creature had shown itself worthy of a soul, can we really say for certain that God would have been less than pleased with His new Eve and Adam? I don’t think so” [10].

This is a workable model of God, and one that nobody can disprove or rule out. But it is also not testable or falsifiable, as is the failed model of the Judeo-Christian Islamic God who interacts with his creation on a daily basis and takes an active interest in the lives of humans. Moreover, it is not a god for which any evidence is forthcoming, and the “absence of evidence” argument, as discussed in Part 2, still applies to the dice-throwing deistic god of Barbour and Miller.

Emergent Theology

Another common notion entertained by the premise keepers is that god emerges from natural processes, similar to the way consciousness emerges from organic brain matter. The notion of emergence, which grew out of complexity theory, suggests that certain properties and principles not built into material systems can arise out of those material systems, which initially were composed only of particles bouncing off one another. In his book Mind and Emergence, theologian Philip Clayton identifies downward causation as the most important defining characteristic of emergence. Downward causation is “the process whereby some whole has an active non-additive causal influence on its parts” [11]. This is a process for which the only actual evidence in nature are trivial instances with no metaphysical import, contrary to the theologians’ claims. Clayton himself acknowledges this mundaneness when he points out that claimed instances of downward causation “are clearest when the ‘whole’ in question is something we standardly pick out as a separate object in the world, such as cells, organs, organisms, and objects built by humans” [12].

A common example invoked by writers on emergence is water. There is no property of wetness in the individual particles that form water, namely hydrogen and oxygen atoms. But when two hydrogen atoms join with one oxygen atom, they produce water molecules which collectively possess the property of wetness. And so, wetness is said to “emerge.”

Sure, wetness emerges. But this fact does not in any way imply either that emergence is therefore a supernatural process, or that something more than reductive physics is needed to explain emergent properties, as the premise keepers are trying to insinuate.

Interestingly enough, a number of Christian theologians have come to accept the fact that we can safely conclude beyond a reasonable doubt that there is no such thing as a soul, a spiritual substance that exists in each person separate from their material selves. As Christian theologian Nancey Murphy admits, “It is undeniable that a serious theological problem awaits solution” [13]. She acknowledges that “biology, neuroscience, and cognitive science have provided accounts of the dependence on physical processes of specific faculties once attributed to the soul” and that “the neurosciences have completed the Darwinian revolution, bringing the entire human being under the purview of the natural sciences” [14]. She is a proponent of the position which has come to be known as nonreductive physicalism, which she describes as follows:

Applied to the specific area of studies of consciousness, it [nonreductive physicalism] denies the existence of a nonmaterial entity, the mind (or soul) but does not deny the existence of consciousness (a position in philosophy of mind called eliminative materialism) or the significance of conscious states or other mental (note the adjectival form) phenomena. In brief, this is the view that the human nervous system, operating in concert with the rest of the body in its environment, is the seat of consciousness (and also of human spiritual or religious capacities). Consciousness and religious awareness are emergent properties and they have top-down causal influence on the body [15].
In other words, nonreductive physicalism accepts reductive accounts of human beings as purely physical organisms, but in addition to rejecting the dualistic notion of a mind or soul separate from the physical constitution of conscious creatures, nonreductive physicalism also denies that reductive physics and biology possess any causal role in bringing about higher capacities such as consciousness.

Physiological psychologist Warren S. Brown of Fuller Theological Seminary suggests that what we call “soul” is an emergent property which arises from the capacity for personal relatedness among humans. Personal relatedness, says Brown, is made possible by a number of cognitive functions which he argues are either qualitatively or quantitatively unique to humans. These include language, a theory of other minds, episodic memory, future orientation and emotional modulation. While he rejects body-soul dualism and admits that the functions which allow for personal relatedness depend on lower abilities for their existence and operation, Brown argues that they cannot be reduced to those lower abilities. Something more is required to account for them. He further asserts, without providing any evidence, that human cognitive capabilities exert “downward causative influence” on those lower abilities [16].

So, while the premise keepers have seemingly come to terms with the results of modern neuroscience which demonstrate conclusively that thinking is a purely physical process, as are emotions, they proceed to argue that perhaps, as humanity and the rest of the universe evolves further, out of our materialistic brain chemistry will emerge a tendency toward a point of ultimate complexity. This point of ultimate complexity, which the theologians want to call “God,” is often referred to in the context of the Omega Point, an idea originally proposed in 1955 by Pierre Teilhard de Chardin, a Jesuit priest and paleontologist [17].

Murphy, Brown and other proponents of top-down emergence and nonreductive physicalism still seem to be in denial of another fact, namely that physics implies reduction by definition. If one wants to philosophize it by suffixing an ism onto the term “physical” and talk about physicalism while rejecting reductive accounts which make sense of its constructs, why not deny altogether the primacy of the hard science they are trying to reconcile with theology in the first place and present the physical sciences as simply another branch of theology? As it turns out, some god-believing physicists do just this.

Christianity and Eternal Life as Physics

Physicist Frank Tipler of Tulane University, probably the most enthusiastic proponent of Teilhard’s “Omega Point” idea among scientists today, has been rightly described by biologist and popular atheist blogger PZ Myers as “one weird dude” [18]. Tipler promotes some of the most incredibly amusing and bizarre ideas one can hope to come across in his field. He has made a career out of interpreting modern physics in terms of both Christianity and the ultimate movement to the Omega Point, and in trying to persuade his colleagues and readers that theology is a branch of physics. Tipler was introduced in Part 2 of this series as the one who announced in 2007 that he had come up with a physics equation that he claimed proved the existence of God, stating that “as long as you're using . . . general relativity, and quantum mechanics, you are forced to conclude that God exists” [19].

Some years before this, Tipler authored a fascinating book titled The Physics of Immortality, in which he purports to “absorb theology into physics, to make Heaven as real as an electron [20].” Let me summarize his interpretation, which is well worth exploring for those not familiar with it.

Tipler begins the book by asserting that the planet Earth is doomed to be engulfed by the Sun’s outer atmosphere, into which the planet will then spiral, in about 7 billion years. If the human species is to survive into the far future, we must move off the planet and colonize space. In less than fifty years, Tipler is convinced that humanity will have succeeded in building interstellar robot probes which possess intelligence and which will leave Earth to explore the universe and colonize it with the DNA codes of humans and other life forms. These intelligent robots will evolve over time into ever more complex artificial intelligence systems. In about a billion-billion (or 1018) years from now, the universe will have reached maximum expansion and will begin to contract. By harnessing the chaos equations governing universal dynamics, the intelligent robots we created will control the rate and direction in which the universe collapses back down to a single point of infinitesimal size (the Omega Point).

Now, when a system gravitationally collapses, any clocks contained within it run slower and slower as the collapse progresses. This means that an infinite amount of time is available while the collapse of the universe takes place. During this infinite time, everything that can and has happened can be repeated over and over again. The advanced robotic life forms will thus be able to regenerate every single human that has ever existed and make them relive their life over and over again. Not only will every single human being who has ever lived repeat the life they had the first time around, but they will live every other possible life. In other words, everybody will do every possible thing they might have done in their lives. This, then, is the immortality which Tipler envisions: a coming infinity of time in which everything can and will happen, the mechanism for which he works out from advanced physics.

In 2007, Tipler published The Physics of Christianity, a book in which he presents pure reductive physics explanations for the resurrection of Jesus, his virgin birth, and his miracles. All of these events occurred naturally, says Tipler, and no postulate of supernaturalism or divine intervention is required to account for and explain them.

Tipler speculates that when Jesus resurrected from death, his entire body was converted into neutrinos, elementary particles which interact very weakly with normal macroscale matter and thus are invisible, allowing Jesus to walk through solid walls. By reversing the conversion process, Jesus can materialize out of nothing and thereby reappear before his disciples [21].

Jesus’ virgin birth could have occurred by the natural inducement of oocyte (egg cell) division in the female body of Mary. Tipler points out that the phenomenon of parthenogenesis has been known to occur in nature, resulting in about one in thirty human births. However, because females have two X chromosomes while males typically have the XY combination, natural virginal births should always result in a female child, since all the genes come from the mother in those rare cases. Tipler gets around this problem by noting that 1 in 20,000 males have two X chromosomes, their maleness coming from a key gene (the SRY gene). This SRY gene may have been inserted into one of Mary’s X chromosomes and inactivated by a standard RNA mechanism which turns off genes. The gene would then be activated in Jesus, who in this scheme results from the division of one of Mary’s oocytes prior to its becoming haploid, thus allowing Jesus to be born a male [22].

Jesus’ miracles are said by Tipler to have been achieved by the electroweak quantum tunneling mechanism, basically the same as that which allowed the resurrection of his invisible body and re-materialization before his disciples: the annihilation/conversion of protons and electrons into neutrinos and vice versa. When Jesus walked on water, the protons and electrons making up the layer of water under his feet were annihilated, creating neutrinos in their place. This means Jesus would have been kept from sinking by the upward recoil resulting from the rapid motion of these neutrinos as they move downward with high momentum [23].

Tipler even has a physics account of the coming “Great Tribulation” described in the Bible’s more prophetic passages. Tipler is convinced that we as a species are doomed to destroy ourselves within the next fifty years. Recall the intelligent robot probes we will send off into space, as discussed above in reference to Tipler’s previous book. In order to do this, humans will first need to develop a highly-efficient form of propulsion, which Tipler believes will be found when collective humanity discovers the means to control the matter annihilation process used by Jesus. That dematerialization mechanism will provide each of us with a tabletop weapon so powerfully destructive that it makes nuclear bombs look like spitballs by comparison. Our inability to control this weapon will mean our demise at our own hands [24]. Thus, the very process that will ultimately bring about the resurrection of each and every human being to eternal life in the Omega Point – the sending off of intelligent robots into the cosmos who will later resurrect us in the form of computer emulations – will also be the cause of our temporary destruction in less than fifty years.

Traditional Theology versus “Sokaled” Theology

In reading Tipler’s works, one is led to wonder if he is actually serious. Perhaps he is playing a great hoax on his colleagues and readers, in similar fashion to the famous Sokal hoax. In 1996, physicist Alan Sokal of New York University wrote an article for the peer-reviewed journal Social Text in which he proposed that the laws of physics are little more than mere social and linguistic conventions and that science must be subordinated to political strategies rather than to reality in order to be liberated [25]. In writing this article, which was accepted by the peer-review board of the journal, Sokal intentionally filled it with pseudoscience and nonsensical but obfuscated postmodern gibberish. His prank highlighted one of the many problems with postmodernist academics, namely the tendency of postmodernists to communicate using a façade of theoretical sophistication to the exclusion of internal logical consistency. As Sokal put it in a Lingua Franca article, in which he revealed his Social Text article as a satire, “Incomprehensibility becomes a virtue; allusions, metaphors, and puns substitute for evidence and logic. My own article is, if anything, an extremely modest example of this” [26].

This is a fitting description of Tipler’s writings. Although he is careful and rigorous in his use of well-established science and precise mathematics (and so is not postmodern in that particular sense), he has misused and abused the physics he knows in trying to treat theology as a branch of physics and in making up a practically fictional universe from the depths of his fertile imagination. It should be obvious that no Christian layperson talks or even thinks the way Tipler and other “theophysicists” do on a regular basis.

This is a problem for the evolution-theologians who want to massage their model into consistency with the basic tenets of Christianity. Many want to maintain that the model of a god who throws dice is consistent with what we find in the Bible. However, their model is not at all consistent with what most lay believers and worshippers think and believe. The theologians’ “Sokaled” god is not the one being prayed to by the average layperson in the pew. It is in fact unrecognizable to them, and most of those people in the pews would view the god of the theologians as a heresy. After all, the theologians’ model denies many of the essential traditional precepts of the Catholic Church, for example, one of which states that Jesus was a divine being.

So in one sense, the premise keepers have come to grips with reality, only to then retroactively define their god back into consistency with the findings of modern science. Because they have come to accept that the broader model of god can no longer be supported, they have scaled back and attempted to fit god into whatever nooks and crannies they possibly can. But they then use their model of god as a justification for religion itself, the exercise of which is completely independent of and separate from the idea of god they have conceived. The premise keepers want to argue that religion itself is good for society and individuals, whether or not there is a god behind it and regardless of whether their god is even identifiable by the worshippers.

Moreover, the “intention” of the evolution-theologians’ god is indistinguishable from a complete absence of intention. In other words, their god may as well not exist, because if this god does no more than roll the cosmic dice and allow whatever happens next to play out naturally, then there is no reason for supposing that he exists in the first place. Unless, that is, the chance-theologian resorts to the classical First Cause argument, which has been soundly refuted for over 400 years. And besides, there can be no benefit whatsoever to believing in the god who throws dice. He does not hear prayers, much less answer them, and he does not interact in any way with his chance creation. Again, he might as well not exist.

Conclusion: Rational Christians Are Effective Atheists

Because the professional reason-oriented theologians posit a god that may as well not exist, it follows that they may as well be atheists. That is, they are effective atheists. This renders their adherence to Christianity all the more perplexing. If they accept that god throws dice and allows chance processes to take over, they must accept that Jesus himself was just another accident of history, as are all the rest of us. Nancey Murphy expresses this concern when she writes, “A revised concept of the person has implications for thinking about the person of Christ. Recognition of the centrality of resurrection to Christian teaching, combined with recognition of the continuity of humans with the whole of nature, calls for reconsideration of the scope of God’s final transformative act” [27].

Then again, it is not even clear that the majority of today’s professional theologians, even the ostensibly Christian ones, actually believe in Jesus as the divine savior of humankind. Consider, for example, the case of John Shelby Spong. A retired bishop of the Episcopal Church, Spong is the author of many books promoting liberal and progressive Christianity and debunking fundamentalist doctrine. In his 2007 book Jesus for the Non-Religious, Spong gives strong, reasoned arguments as to why the virgin birth of Christ could not have happened, why the whole story of the Nativity of Christ could not have played out as depicted in the Bible, why students of history can safely conclude that the story of Christ’s resurrection is not historical and the story of his ascension is a myth. By the time Spong concludes the first part of his book, practically nothing of the Gospel narrative survives his critical examination. He summarizes his findings as follows:

The first stage of our faith journey, the clearing out of distortions in the way we view the Jesus story, is complete. The literalness of centuries of misinterpretation of the Jesus story has been broken open. The pieces lie before us in frightening array. Jesus was born in a perfectly normal way in Nazareth. His mother was not the icon of virgin purity. His earthly father, Joseph, was a literary creation. His family thought he was out of his mind. He probably did not have twelve male disciples. He had disciples who were both male and female. He did not command nature to obey him. He did not in any literal sense give sight to the blind, hearing to the deaf or wholeness to the paralyzed and infirm. He did not raise the dead. There was no stylized Last Supper in which bread was identified with his broken body and wine with his poured-out shed blood designed to symbolize his final prediction of death. There was no betrayal and no romance connected with his death, no mocking crowd, no crown of thorns, no words from the cross, no thieves, no cry of thirst and no darkness at noon. There was no tomb, no Joseph of Arimathea, no earthquake, no angel who rolled back the stone. There was no resuscitated body that emerged from that tomb on the third day, no touching of the wounds of Jesus, no opening by him of the secrets of scripture. Finally, there was no ascension into a heaven that exists above the sky. . . . All of these narrative details were the creation of a community of people who individually and corporately had an experience that they believed was of God in the human life of one Jesus of Nazareth [28].
Spong is by far the most honest Christian I know, and probably one of the most honest Christian writers of our time. His many years of close study have convinced him that there is little to no historical truth to be found in the Gospels, and he has not shied away from presenting the results of his research, however devastating to the tenets of traditional Christianity. It is not often nowadays that we find a Christian author, even a liberal one, writing as Spong does when he says that the “resurrection language of the gospels is literal nonsense” [29].

I am in complete agreement. If one came across many passages in Spong’s books unattributed, he or she would be excused for thinking that an atheist wrote it. However, through all this, Spong the self-identified Christian somehow manages to retain a dimly-perceived concept of Jesus with which he has lived his whole life and which he believes has brought him a feeling of happiness and fulfillment. He is still somehow able to find in Jesus a name for something by which he accounts for the goodness he sees in life. At the end of Jesus for the Non-Religious he writes,

It is through the expanded consciousness of these transcendent experiences [life, love and being] that I look at Jesus of Nazareth and assert that in his life I see what the word “God” means. My view of God and even of the God I meet in Jesus is a subjective description of what I believe is an objective reality.

It matters not to me whether any of the details of the cross story are accurate historically. I have long been convinced that they are not, since as I have already suggested, the gospels appear to be liturgically crafted documents based not on eyewitness accounts but on ancient Hebrew sources. They do, however, present a memory of Jesus of Nazareth, a portrait that I still find to be astounding [30].

Spong’s Jesus is just a name, nothing more. His Jesus is a concept not based on anything of substance, but rather on subjective feelings and sentiments. And while the various scientist-theologians reviewed above are more oriented toward hard science fuzzy feelings of the Spong variety, they too champion a model of theological belief of which the sole justification is their subjective aversion to a fully materialistic account of life, the universe and everything. This materialistic, fully reductive account is all that is required of the data, and many of them are good enough scientists to be fully aware of this deep down. The non-interventionist god of the scientist-theologians can thus be safely ruled out on the basis of its status as an unnecessary and post-hoc ancillary hypothesis.

Paradoxically, the scientist-theologians’ attempts to reconcile their conception of god and religious belief with the findings of modern science represents a fundamental unwillingness to come to terms with the fully reductionist picture of the universe which the data presents to us. At least the religious anti-science fundamentalists live in their own self-contained albeit ridiculous universe of their own dogmatic making which, while completely divorced from the real world, operates consistently according to its own rules which are provably incompatible with reality. Trying to harmonize religion and science succeeds only in a confused and inconsistent worldview unrecognizable by either traditional religion or modern science.

The Scientific Verdict on God (Part 3): The End of Classical Theism

Deus does not exist
But if he does he'd want to get down from that cloud
First marzipan fingers then marble hands
More silent than silence and slower than slow.

~ The Sugarcubes, “Deus” (from the 1988 album Life’s Too Good)

In Part 2 of this series, I made the case that science is justified in weighing in upon claims of the supernatural, and that it violates no jurisdiction by doing so. Now that that argument has been made, we can now move on to put the various models of God to the test to see how well they stand up to scientific scrutiny. My thesis in this essay is that the existence of a personal God, the God of classical theism, is a scientific and philosophical impossibility.

Arguments for God's existence continue to be a topic of intense debate within discussions of the philosophy of religion. I want to make the case that it is high time philosophers of science entered into the question of God with equal intensity. Here I must draw a distinction between questions concerning the concept of God and questions concerning religious practice. All religions, regardless of their relative antiquity or modernity, can easily be demonstrated through critical scholarship to be fallible human inventions. However, the more important and interesting inquiry (at least for me)comes when we put aside theology, all the creeds and the bells-and-whistles with which people dress up their conception of a deity, and consider, if at all possible, only the God concept itself.

The proposition “God exists in reality” is a hypothesis, and as such it requires objective verification and evidential demonstration to be justified. The particular model of a god I am examining here is that of the personal “Tinkering God” introduced in Part 2 of this series – the one who is said to be intimately involved with and active in his creation. According to classical theists, not only does this God play a very important role in every single event in the universe, from atomic phase transitions in far-off galaxies to the falling of a leaf on the ground here on Earth, but he also actively listens to every human thought. As I noted in Part 2, this God should be eminently detectable by the tools of science, based on the predictions of the model itself, that is, the ways in which this god is said to make his presence known within the natural world.

Before examining the various classical scientific arguments for the existence of the Tinkering God, let’s review what the theistic worldview is up against.

I. ANTI-THEISM ON THE OFFENSIVE

The Problem of Evil

The most devastating argument that weighs against the hypothesis that the God most people believe in exists is the problem of evil. There is an irreconcilable conflict between the conception of an omnipotent, all-wise and all-loving God and the existence in our world of human cruelty and natural disasters. How can an omnipotent (that is, all-powerful) being who is also the epitome of goodness and love possibly allow such evils as war, wholesale genocide, private murder and economic depressions to run indiscriminately rampant and lay waste to his creation? If any higher creative being must be proposed, it would be eminently more reasonable and plausible to posit the existence of a demonic god than a good and wise one. The only other reasonable option open to the theist in the light of the problem of evil is to say that their god is not in fact all-powerful and is therefore powerless to restrain evil. This latter option reduces the theists’ god to utter uselessness; if such is the case, there is no sound basis in reality to all the fears with which religion threatens people and no need for any creed or worship of any kind. Chapman Cohen writes,

If there is a God, he is quite careless of human well-being or human suffering. The deaths of a hundred thousand men mean no more to him than the deaths of a hundred thousand ants. A couple of million men locked in a death struggle on the battlefield is only a replica of the struggle that has been going on in the animal world throughout time. If there be a God, he made, he designed all this. He fashioned the hooks for the slaughter, the teeth for the tearing, the talons for destruction, and man with his multiplied weapons of destruction has but imitated his example. A world without God, and in which humanity is gradually learning the way to better things, is an inspiration to renewed effort after the right. A world such as this, with God, is enough to drive insane all with intelligence enough to appreciate the situation [1].
Theists have yet to explain how a benevolent, loving, omnipotent father-being – who personally guides the destiny of each and every individual – can allow such monstrosities as war, the effects of racism, hatred and bigotry of all kinds stemming from jealousy and fear, the gross disparity between rich and poor worldwide, mass poverty and starvation, the extreme pain and suffering that can be witnessed by touring through any hospital, etc., etc. Consider: if any human father consciously and purposefully allowed his children to starve, he would be imprisoned and indicted. Yet we are told we have a “Heavenly Father,” one we are of course powerless to indict even as he neglects us for eons. If such a god does exist, he is the very antithesis of goodness and wisdom, and it is humanity’s duty to cease paying any tribute to him through worship. In Sunday schools all over the world, theists tell children the fantastic story of how the Son of God miraculous multiplied five loaves of bread and two fishes to feed a large multitude. Yet today millions upon millions of people starve and languish in poverty even as they piously utter “Our Father which art in Heaven, give us this day our daily bread” out of a sense of fear and duty to this deity who has apparently grown tired of performing miracles of any kind. In his book Mind and Matter, the late philosopher C.E.M. Joad summed up the problem of evil forcefully and eloquently:
If we suppose that the universe is the creation of an Omnipotent and Benevolent God, it becomes necessary to ask how pain and evil arise. Pain and evil are either real or unreal. If they are real then God, who, being omnipotent, was bound by no limitations and constrained by no necessities, willfully created them. But the being who wilfully creates pain and evil cannot be benevolent.

If they are unreal, then the error which we make when we think them real is a real error. There is no doubt that we believe we suffer. If the belief is erroneous, then it follows that God wilfully called falsehood into existence and deliberately involved us in unnecessary error. It follows once again that God cannot be benevolent.

If we regard pain and evil as due to the wickedness of man and not as the creation of God, we are constrained to remember that man himself is one of God's creations (God being conceived as all creative), and received his wickedness, or his capacity for it, from whom? If we say that man had no wickedness to begin with but willfully generated wickedness for himself, we have to face the double difficulty of accounting for: (a) How man, who is an emanation from God, can will with a will of his own which is not also a piece of God's will; and (b) how a benevolent God could, assuming pain and evil to be a purely human creation, deliberately allow them to be introduced into a world that knew them not, when it was open to Him to prevent such introductions [2].

The Hiddenness of God and the Problem on Nonbelief

The very presence of nonbelief poses a serious problem to the viability of a theistic worldview, a problem closely related to the problem of evil. Theists often argue that the reason we do not observe the effects that should obtain all around us if a personal and active God existed is because this God has purposefully gone to great lengths to hide himself from us in order to allow faith to fully play its part in building our character.

But if this is the case, God is not good. If the only nonbelievers in the world were “bad people” who stubbornly refused to believe in God’s existence simply because they did not want to believe, then that would one thing. However, the vast majority of nonbelievers (certainly all those I have known, met and read) are very open to any and all evidence that might be presented. “Show me the evidence, and I will believe” has been the continual refrain of most in the atheist community, including myself. The fact of the matter is that we still do not believe. Therefore, if the God of the theists really does exist, he must be intentionally hiding himself from people who are open to belief in God and thereby cutting himself off from us skeptics.

In fact, this distinctly Calvinist interpretation seems to be the view of most evangelical Christians, whether they consciously identify as Calvinists or not. Many believe that their God really has chosen only a select few to be the recipients of his revelation (all those who believe this, of course, are part of that select group). The chosen few are the people God wants to spend eternity with, for whatever reason, and everybody else is doomed to suffer eternally outside his presence. Now, while it is true that this Calvinist model of God goes a long way toward explaining the Problem of Evil, it is certainly not an explanation Christians want to accept. The explanation that presents itself is that God himself is evil. How do we reconcile the rampant, unrestrained evil in the world with the existence of God? Simple: the Calvinist God of the Christians is pure evil.

Needless to say, this is not the kind of God most people want to believe in. Most people want to believe in a good god, a god that has great love for humanity. But unfortunately, that is precisely the kind of god we can definitively rule out as impossible. Why? Because there should be abundant evidence for a good god, if in fact there existed a good god who did not intentionally and purposefully conceal himself from nonbelievers who are open toward and waiting for positive evidence of the god’s existence to come to light.

Thus, the very hiddenness of God – quite apart from any consideration of the phenomenon of nonbelief – is damning to the god hypothesis. If the kind of God that most people believe in actually existed, certainly we should expect such a being to have revealed himself to humankind in such a way that there can be no doubt as to his existence and presence in the universe. Furthermore, if any religion is true, this God (if he is not evil, psychotic or otherwise mentally-challenged) should have no qualms or hesitation whatsoever in revealing which is the true religion and why it is true – to all people at all times and in an unambiguous and unmistakable manner – instilling into the collective minds of all people everywhere the True Creed so that no doubt can possibly enter into any skeptic’s mind. Needless to say, this has not happened. “Why, we may ask,” writes philosopher John L. Schellenberg in his book Divine Hiddenness and Human Reason, “would God be hidden from us? Surely a morally perfect being – good, just, loving – would show himself more clearly. Hence the weakness of our evidence for God is not a sign that God is hidden; it is a revelation that God does not exist [3].” Presumably, God could easily, at any moment, exercise his claimed omnipotence to reveal his existence with force sufficient to overpower all traces of doubt and skepticism. Yet humanity has been futilely searching for millennia for even just the slightest evidence of his existence. In his little-known but important book The Churches and Modern Thought, Philip Vivian highlighted the problem succinctly: “How is it that God allowed earnest and learned divines to commit themselves to arguments in proof of His existence, the subsequent overthrow of which has been a potent cause for unbelief? [4]” As for the hundreds of millions who think they have already found a solid faith, William McCarthy asks,

If there are and have been gods, why hasn’t, at least, one showed up? Why do we have to pay their self-appointed, man-selected priests to tell us about them? If the gods wish to save our souls (?) why don’t they, in a few simple sentences, tell us what to do? Why do they permit their vicars to tell us so many conflicting stories about them? The agents of Jehovah alone have pointed out fifteen hundred different mythical roads to heaven, all leading in different directions . . . Why doesn’t god tell the faithful who is right? Is there a god? Would a god permit such confusion and damn foolishness? We wouldn’t [5].
For the sake of argument, let us accept for a moment the theist worldview as a hypothetical exercise, and assess the situation we find ourselves in given the truth of that worldview. The situation, which I have described in five parts, is as follows:

1. God created the universe but purposefully constructed it in such a way that it looks to all appearances and observation as if no god created it. In fact, God has gone out of his way to hide himself from all people in every conceivable aspect.

2. However, in a bizarre move on his part, God endowed his favorite creation, humankind, with brains that work with tools called “reason” and “logic,” tools which allow us to discover and learn about the physical world around us.

3. We develop science, and every discovery we make with the brains God gave us continues to demonstrate that either there is no God, or he is increasingly running out of places to hide.

4. On top of this all this madness, God divinely inspires a book which tells its readers that he will help anyone come to know him, as long as they are simply willing and open to understanding and receiving him.

5. And yet, there are millions of people like me – who are certainly open to any evidence that would support the claim that a Supreme Intelligent Creator and Ruler exists – who continue to find it impossible to simply decide to believe despite the utter absence of evidence. And the theists would have us believe that their God has intentionally hidden himself from honest doubters and skeptics.

II. THEISM ON THE DEFENSIVE

The Cosmological First Cause Argument

A whole raft of classical arguments favoring the existence of God have been advanced for centuries and continue to be invoked today, despite the fact that they have many times been refuted in short order (if the Bible is correct about anything, it is that “there is no new thing under the sun”). Among these antiquated and obsolete apologetic items is the “First Cause argument,” which assumes as its a priori starting point that every event must have a cause, and that therefore the universe must have had a cause, which theists call “God.” But by predicating a First Cause which they assert to be a “cause that was uncaused,” the theist simply pushes the conundrum it seeks to solve further back. They create a larger mystery to explain a comparatively lesser mystery, and thereby fall into logical absurdity. If everything must have a cause, then we are not justified in making an arbitrary exception for a postulated First Cause. Who, it needs to be asked, created God? And who or what created that creator? To say that this First Cause has always existed and was never created is to deny the foundational and basic assumption with which the argument was started in the first place!

Moreover, even if it is reasonable to assume that some First Cause always existed, why is it then unreasonable to assume that the universe itself is what always existed, rather than a deity? Postulating the necessity of a First Cause in order to affirm the existence of a god through reason is a complete rejection of all logical procedure, because the First Cause argument seeks to explain that which is provisionally known (the existence of the material universe) with an unknown (God).

Furthermore, while we can conceive of a cycle of virtually endless causes for any given physical phenomena, it is impossible to conceive of a single ultimate cause for any one obtained object or event. Science provides no justification for tracing causes and effects backward to one simple First Cause. In his excellent book Theism or Atheism: The Great Alternative, Chapman Cohen reminds us that “Cause and effect are not two separate things; they are the same thing viewed under two different aspects. . . . If cause and effect are the expressions of a relation, and if they are not two things, but only one, under two aspects, ‘cause’ being the name for the related powers of the factors, and ‘effect’ the name for their assemblage, to talk, as does the theist, of working back along the chain of causes until we reach God, is nonsense [6].”

Today physicists are confident that no laws of physics were violated or altered as a prerequisite for the universe to emerge into existence. But that was once one of the best arguments for the necessity of a First Cause, because as early as two hundred years ago it appeared that certain laws of physics, such as energy conservation, did indeed have to be violated in order for the universe to come into being. Physicists today know for a fact that energy conservation was not broken, because we know that the total energy content of the universe is exactly zero; this means no energy was ever required to produce our universe in the first place. We have no evidence that any other laws of physics were similarly violated, either.

But the First Cause argument contains within it the seeds of the next response resorted to by theologians even today: “Where did the laws of physics themselves come from?” Modern science, not theology, gives us the answers to this question and reveals the fundamental weakness in the First Cause argument. In his book The Comprehensible Cosmos, physicist Victor Stenger undertakes to show how physicists have come to derive the so-called “laws” of physics [7]. Stenger is interested in accomplishing this daunting task as convincingly as possible, and this obliges him to invoke heavy mathematics of the sort many people cannot read [8]. Stenger’s explanatory account of physical laws as restrictions imposed by observers on themselves is consistent with what would be expected if the universe was not designed by a lawgiver handing down laws from above.

There is a sound basis for making the case for an uncreated universe that actually does not require a great deal of technical language. Very simply, when a physicist writes a model, he or she is forced to write it in a certain way, namely in such a way that it is independent of the reference frame of the particular observer, what physicists call the “point-of-view.” This required perspective Stenger calls point-of-view invariance: “The models of physics cannot depend on any particular point of view [9].” When this invariance of perspective is achieved, it is nothing short of incredible how all the pieces of the cosmological puzzle fall consistently into place within a wholly naturalistic framework “Thus,” writes Stenger, “the conservation principles follow from point-of-view invariance. If you wish to build a model using space and time as a framework, and you formulate that model so as to be space-time symmetric, then that model will automatically contain what are usually regarded as the three most important ‘laws’ of physics, the three conservation principles. . . . further symmetries will require the introduction of other ‘laws,’ not to govern the behavior of matter, but to govern the behavior of physicists so that when they build their models, those models will be point-of-view invariant [10].”

Again, the provisionally-derived “laws” of physics, formulated based on human observation and experimentation, are exactly what they should be expected to be if our universe came into being from nothing. Stenger shows in his book that,

[T]he laws of physics do not follow from very unique or very surprising physical properties of the Universe. Rather, they arise from the very simple notion that whatever mathematics you write down to describe measurements, your equations cannot depend on the origin or direction of the coordinate systems you define in the space of those measurements or the space of the functions used to describe those laws. That is, they cannot reflect any privileged point of view. Except for the complexities that result from spontaneously broken symmetries, the laws of physics may be the way they are because they cannot be any other way. Or, at least they may have come about the simplest way possible [11].
The next question theologians ask is: why is there something rather than nothing in the first place? This question assumes that nothing should in fact be a more natural state than something. But why should nothing be the most natural state? As it turns out, we have an answer to the theologians that again comes from hard science. In physics, the most highly symmetric systems we encounter tend to be less stable. For example, a raindrop will freeze into an ice crystal, which does have structure but lacks the level of symmetry the raindrop possessed. Let us stress this: A spherical raindrop has symmetry, while an ice crystal has structure, which is caused by broken symmetry. Likewise, a pencil sitting on a table possesses rotational symmetry around its vertical axis. But that symmetry is highly unstable; if it falls over, that symmetry is broken. Many other examples abound, magnets being a particularly helpful one. Many examples from everyday physics demonstrate conclusively that the more symmetrical a system is, the less stable it will be. Physical systems therefore naturally tend to undergo phase transitions from more symmetric to less symmetric.

Consider: there is no thing in the universe more symmetric than nothing. Therefore, the state of nothingness is highly unstable. As Stenger explains in his book God: The Failed Hypothesis,

So where did the laws of physics come from? They came from nothing! Most are statements composed by humans that follow from the symmetries of the void out of which the universe spontaneously arose. Rather than being handed down from above, like the Ten Commandments, they look exactly as they should look if they were not handed down from anywhere. And this is why, for example, a violation of energy conservation at the beginning of the big bang would be evidence for some external creator. Even though they invented it, physicists could not simply change the “law.” It would imply a miracle or, more explicitly, some external agency that acted to break the time symmetry that leads to conservation of energy. But . . . no such miracle is required by the data. . . .

[T]he natural state of affairs is something rather than nothing. An empty universe requires supernatural intervention – not a full one. Only by the constant action of an agent outside the universe, such as God, could a state of nothingness be maintained. The fact that we have something is just what we would expect if there is no God [12].

In other words, the existence of our Universe is the natural consequence of the spontaneous collapse of the inherently unstable symmetries of the void. In a Scientific American article written in 1980, Nobel laureate physicist Frank Wilczek provides a succinct mechanism for how this symmetry-breaking may have occurred in the early universe: “One can speculate that the universe began in the most symmetrical state possible and that in such a state no matter existed; the universe was a vacuum. . . . The second state had slightly less symmetry, but it was also lower in energy. Eventually a patch of the less symmetrical phase appeared and grew rapidly. The energy released by the transition found form in the creation of particles. This event might be identified with the big bang. . . . The answer to the ancient question ‘Why is there something rather than nothing?’ would then be that ‘nothing’ is unstable [13].”

Thus, in responding to theists who invoke the First Cause line of argumentation, many atheists make the slightly mistaken claim that naturalists are not positing a “something-from-nothing” scenario. As we have seen, it is not necessary to distance one’s arguments from this scenario. Despite the difficult philosophical twists one gets into when attempting to describe nothingness, one can plausibly imagine a state of absolute absence of matter, energy and space curvature, and still be able to describe that empty state. To see why this is the case, consider the possible ways of measuring a photon radiation field. This field is described quantum mechanically with a harmonic oscillator, that is, in terms of a series of energy levels. As the physicist applies what is called a violation operator, a wave function for each energy level is specified by the oscillator. When the measurement is at its lowest level and all the photons have been removed, a wave function still remains. It is a wave function that is describing “nothing.” Thus, it is possible to mathematically describe the property of nothing without any problem, and one can derive a number of plausible scenarios and mechanisms by which something comes from nothing.

The world-renowned physicist and mathematician Stephen Hawking made the same case for a “something-from-nothing” scenario in his J. Robert Oppenheimer Lecture delivered in March 2007 at the University of California at Berkeley. Hawking likened the spontaneous quantum emergence of the universe to “the formation of bubbles of steam in boiling water [14].” The plausible naturalistic scenario proposed by Hawking became the subject of his 2010 book The Grand Design, co-written with Caltech physicist Leonard Mlodinow. They conclude, “Because there is a law like gravity, the universe can and will create itself from nothing . . . Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going [15].” The analogy to the expanding surface of a bubble is again invoked in Hawking’s and Mlodinow’s book to describe the universe coming into existence via random quantum fluctuations through which the current universe tunneled from a previous one:

Our picture of the spontaneous quantum creation of the universe is then a bit like the formation of bubbles of steam in boiling water. Many tiny bubbles appear, and then disappear again. These represent mini-universes that expand but collapse again while still of microscopic size. They represent possible alternative universes, but they are not of much interest since they do not last long enough to develop galaxies and stars, let alone intelligent life. A few of the little bubbles, however, will grow large enough so that they will be safe from recollapse. They will continue to expand at an ever-increasing rate and will form the bubbles of steam we are able to see. These correspond to universes that start off expanding at an ever-increasing rate – in other words, universes in a state of inflation [16].
The Argument from Design

The “Argument from Design” and the so-called “Anthropic (or fine-tuning) Argument” are two closely related classical defenses of a god’s existence that are ubiquitously used today and have been for centuries past. Many theists have attempted to deduce the existence of a supernatural creator and sustainer of the universe from the visible features of the natural world. They do this by selectively pointing to instances in nature of “design,” of carefully-balanced regularity and order, and in various examples of beauty to be found in the exploration and study of natural objects.

In the early 1800s, Anglican theologian and philosopher William Paley (1743-1805) famously presented this argument in his book Natural Theology, first published in 1802. A teleological defense of divine causation of nature that was applied on a terrestrial scale, Paley’s argument began with the premise that everything owed its existence to a first cause, which he proceeded to identify as God. The famous “Watchmaker Analogy” was introduced by Paley to illustrate this argument. The structure of the analogy, in Paley's own words, is as follows:

In crossing a heath, suppose I pitched my foot against a stone, and were asked how the stone came to be there; I might possibly answer, that, for any thing I knew to the contrary, it had lain there for ever: nor would it perhaps be very easy to show the absurdity of this answer. But suppose I had found a watch upon the ground, and it should be inquired how the watch happened to be in that place; I should hardly think of the answer which I had before given, that, for any thing I knew, the watch might have always been there. Yet why should not this answer serve for the watch as well as for the stone? why is it not as admissible in the second case, as in the first? For this reason, and for no other, viz. that, when we come to inspect the watch, we perceive (what we could not discover in the stone) that its several parts are framed and put together for a purpose, e. g. that they are so formed and adjusted as to produce motion, and that motion so regulated as to point out the hour of the day; that, if the different parts had been differently shaped from what they are, of a different size from what they are, or placed after any other manner, or in any other order, than that in which they are placed, either no motion at all would have been carried on in the machine, or none which would have answered the use that is now served by it. To reckon up a few of the plainest of these parts, and of their offices, all tending to one result: -- We see a cylindrical box containing a coiled elastic spring, which, by its endeavour to relax itself, turns round the box. We next observe a flexible chain (artificially wrought for the sake of flexure), communicating the action of the spring from the box to the fusee. We then find a series of wheels, the teeth of which catch in, and apply to, each other, conducting the motion from the fusee to the balance, and from the balance to the pointer; and at the same time, by the size and shape of those wheels, so regulating that motion, as to terminate in causing an index, by an equable and measured progression, to pass over a given space in a given time. We take notice that the wheels are made of brass in order to keep them from rust; the springs of steel, no other metal being so elastic; that over the face of the watch there is placed a glass, a material employed in no other part of the work, but in the room of which, if there had been any other than a transparent substance, the hour could not be seen without opening the case. This mechanism being observed (it requires indeed an examination of the instrument, and perhaps some previous knowledge of the subject, to perceive and understand it; but being once, as we have said, observed and understood), the inference, we think, is inevitable, that the watch must have had a maker: that there must have existed, at some time, and at some place or other, an artificer or artificers who formed it for the purpose which we find it actually to answer; who comprehended its construction, and designed its use [17].
Paley's Watchmaker Analogy can be more succinctly represented by way of a simple syllogism:
1. The complex inner workings of a watch necessitate an intelligent designer for the watch.

2. As with a watch, the complexity of X (a particular organ or organism, the structure of the solar system, life, the entire universe, etc.) necessitates a designer.

Paley's reader is invited to imagine walking through a completely natural locale (forests, deserts, and remote beaches have been used in modern rehashings of this analogy), where a lone watch is found. The analogy suggests that this watch obviously cannot be an artifact of the surrounding nature, that it must have been designed by an intelligent agent.

Throughout the rest of his book, Paley extrapolates this analogy to everything encompassed by the natural world. This is an example of fundamentally flawed logic. In the context of the Watchmaker analogy, the only reason one is able to apprehend that the watch in the heath is not an artifact of nature in the first place is because nature and design can be distinguished from each other. We can recognize that which has been made by an intelligent agent for what it is. But how do we know when something has been designed and when it has not? The most important failure in Paley's argument is that it lacks a frame of reference from which to compare design to non-design. Paley, along with modern-day proponents of teleological design arguments for theism, failed to realize that the only reliable indicators of genuine design are those that derive from experience. This being the case, a means of identifying instances of design and non-design independently of the indicators in question is required.

Paley’s design argument also stands as an example of a grossly over-extended metaphor, to which the whole argument is ultimately reducible. While metaphors are often useful for communicating hard-to-grasp concepts to people, they are never the foundation of any strong logical argument. A runaway metaphor cannot be stopped; anything and everything can be applied to it, rendering the necessity of any semblance of logic obsolete. The teleological argument from design is therefore inherently incoherent.

One can then argue, as biochemist Michael J. Behe does in his 1996 book Darwin's Black Box (which, in my estimation, is essentially little more than a glorified and updated restatement of Paley's Natural Theology), that complexity is that elusive standard that determines the criterion for justifiably concluding intelligent design [18]. But in actuality, many things that are very simple look designed. For example, a rubber ball is vastly simpler than a rock, geometrically speaking. The reason such simple objects as a rubber ball are recognizable as a designed thing is because of its regularity, not because it is complicated. In fact, designed things tend to be far simpler than natural things. One of the crucial characteristics of agency that need to be taken into account is that needlessly complex things are never an acceptable standard for building things. We want to make them as simple and as efficient as we possibly can. Natural things are (1) generated by chance and necessity, (2) are functionally unspecified and diverse and (3) often very complex. Things that are designed by agents, on the other hand, are (1) built with intent, (2) are functionally specific and (3) always relatively simple compared to natural material.

It is therefore a basic category mistake to invoke complexity as a measure of design. Complexity more often arises as a result of a lack of planning, than as the result of intelligent deliberation. In addition to this problem, the design arguments characteristic of Paley and his successors also face the problem of lacking sufficient falsifiability: What would a thing not designed by God look like, and how would this non-designed thing operate? These are questions that Paley's argument cannot answer, simply because it was far too simplistic and was not well thought out.

Moreover, the Argument from Design in general has been conclusively overruled by the discovery and subsequent study of natural evolutionary processes [19]. The argument for god from design relies entirely on the assertion that a Mind exists behind, over and above physical phenomena. The motives of this posited Mind, Paley and others believed, could be apprehended by us mortals through studying the forms of animals. While theists today very rarely use Paley’s original formulation of the design argument, a surprising number of theistic arguments, particularly those of the “recent” Intelligent Design (ID) variety, are still based on Paley’s basic faulty assumptions.

An understanding of what biological evolution is and how it operates in the natural world is sufficient to soundly and definitively refute the modern ID position. The evolutionary forces that have been conclusively demonstrated to be at work in nature are not only merciless (recalling again the problem of evil discussed above) but also full of waste; innumerable physiological and biological plans have been deemed by natural selection to be futile, useless and worthless for survival. The ruthless preying of a great many forms of life upon many others was unrelenting throughout hundreds of millions of years of evolutionary history and continues to be unrelenting today. Untold myriads of living organisms have emerged onto the scene, only to suddenly perish before reproducing and contributing to their species’ perpetuation. All in all, the world we find ourselves in is a largely useless one, devoid of ultimate purpose and whose defining characteristic is pain and misery.

The Argument from Design suffers from an extreme case of confirmation bias and selective reasoning. The practice of science, if it is to be objective and impartial, will take note of ugliness and disorder in nature, not just supposed instances of beauty and order. And even if it was true that the earth and its inhabitants are “evolving toward something better” (which is itself a very fundamental misunderstanding of what evolution is and what it is not), this would not lessen or mitigate the impact of the extreme, unimaginable cruelty that predominated throughout all of the evolutionary past. In fact, the Argument from Design is inconsistent with every known fact of the natural world; the steady advance of scientific knowledge has rendered it an impossible position.

The Fine-Tuning Argument

A common theistic argument, closely related to the Design Argument, insists that it is impossible for the inherent properties of natural physical forces, acting on their own, to produce an orderly universe that sustains life. The universe, the theists say, requires constant “directivity” in order to remain on its present course.

It is indeed true that if any one of the physical constants were to be changed by even the slightest amount, life as we know it would be impossible. But it does not then follow that all plausible forms of life could not have existed under those hair-trigger circumstantial changes. This was demonstrated by particle physicist Victor Stenger, who wrote a computer program in the early 1990s called “MonkeyGod,” an interactive module that allows the user to design and run his or her own universe, simply by changing however many constants the user sees fit and then watching to see what kind of virtual universe emerges. Stenger writes, “While these are really only ‘toy’ universes, the exercise illustrates that many different universes are possible, even within the existing laws of physics [20].” Stenger reports on his own experiments with the program as follows:

In previous publications, I have applied MonkeyGod in a computer simulation in which I varied the four parameters randomly (on a logarithmic scale) over ten orders of magnitude. I was mainly interested in seeing how many universes would have stellar lifetimes long enough to allow for some form of life, not necessarily exactly like ours, to evolve.

. . . I used a formula obtained from one reference for the minimum lifetime of a main sequence star. I later adopted a different formula, from another reference, which I thought was more realistic since it gave the maximum lifetime of a star . . . The results are not in general disagreement with that previously published. In fact, as expected, I get results even more favorable to life. While a few stellar lifetimes are low, most are over ten billion years, which is probably enough time for stellar evolution and heavy element nucleosynthesis to occur. Long stellar life may not be the only requirement for biological life, but I have demonstrated that fine-tuning is not necessary to produce a range amenable for life [21].

Thus, the random, unplanned, chaotic emergence of a universe capable of sustaining life as we know it is not as unlikely as most people seem to think. A number of other studies have been published which report on even more sophisticated scientific programs than MonkeyGod, and which have backed up Stenger’s conclusions. The scientific evidence strongly suggests that some form of life may have been possible under a wide range of circumstances that might have obtained [22].

There is also a serious philosophical problem confronting the fine-tuning argument: If God was perfect and omnipotent, why would he need to “fine-tune” the universe for life? If the universe was the creation of an omnipotent and perfect God, it should be capable of producing life no matter what the conditions may be. If humanity was so special and elevated above all other species, being formed in the “image of God” as most theists believe, we should be able to live and thrive in literally any locale, under any condition. We should be able to live in the void of space without any need of a spacesuit or other life-preserving equipment.

However, philosophical and logical objections aside, the practical scientific fact remains that we do not know exactly what kind of universe might be possible under a different set of constants. We can make careful calculations, of course, but in the end we still do not know for certain. Science is an empirical discipline, and the totality of our collective experience is based on just this single universe we find ourselves inhabiting. Still, as we have seen, it is certainly possible to infer what kind of phenomena might manifest in an alternate universe, one with a different set of physical laws and constants. There are no grounds for concluding that this universe is special in any way.

The universe is not fine-tuned for humanity. Rather, humanity is fine-tuned to the universe. As a species, we humans just happened to evolve in the kind of universe that features the constants that make our existence possible. If we were not suited for the world in which we find ourselves, we would not be able to live in it. Obviously, then, the situation in which life evolved was one in which the earth had an atmosphere transparent to what scientists call “visible light” – that extremely narrow region of the electromagnetic spectrum. Our sun produces a large amount of light within that region, so it was only natural that the human eye developed. How absurd and nonsensical would it be to assert that the sun puts out light in that narrow spectrum, and that the earth’s atmosphere is transparent to that spectrum, because our human eyes are sensitive to that region? This is exactly the kind of silly reasoning underlying the fine-tuning argument.

The fact that the present order exists as it does is not enigmatic, mysterious or shocking in the least. What would really constitute an anomaly is if any radical and drastic alteration of the present order should occur before our eyes. The state of the universe at any given moment is the inevitable and unavoidable natural result of all the innumerable physical conditions prevail upon the universe in well-understood ways. These physical conditions demonstrate that purely natural forces are capable of producing the universe as we see and experience it. Regardless of what the ultimate nature of our admittedly provisional models of physical forces may be – whether we are considering electrons, protons, electricity or wave energy – these material forces are alone fully capable of producing a universe such as the one we happen to find ourselves inhabiting.

Moreover, even if these natural and physical forces were not alone capable of bringing a universe into existence, in what conceivable way could an “ultimate, directing and supreme supernatural mathematician” create and install this capacity in natural forces? Unless the capacity for producing the universe as we know it already existed in natural elements themselves, no amount of outside “direction” could have endowed them with that capacity, because this would violate the second law of thermodynamics. Besides, if such an external supernatural and directive agent did exist, why would he/she/it not simply create the universe ex nihilo, without creating natural elements which we observe to possess the inherent capacity for producing the universe on their own?

As we saw above in regard to the cosmological First Cause argument, inherent in the properties of the fundamental physical elements, and in consequence of their specific combinations, is the capability of “coughing up” the universe as we know it from nothing. The operations of a deity are not required for the universe to either come into being or to subsequently sustain life within it. The order that manifests itself in the universe is the necessary and inevitable consequence of the universal persistence of wholly natural physical forces. If an intelligent supernatural force or being does exist, the best possible evidence of its existence would surely come in the form of inhibitive influences that prevent certain events, predicted by established physics, from occurring or obtaining – events that established scientific observation and testing can confirm would have transpired if it was not for such unnatural interference constituting a clear-cut violation of natural law. But such violations have never been observed to occur. I challenge any theist to present any example of an aberration of the normal operation of known forces which cannot be explained by the effect of other known, natural forces.

Furthermore, recall also from the above discussion that a “law” of nature is not a fixed statute, as if set in stone by an external legislator. Rather, they represent pragmatically-functional human inventions, interpretations and summations expressed in falsifiable models that are based on established facts inferred from repeated and tested observation. The phenomena observed by scientists do not operate in a particular manner because they derive from a law. The “law” is declared to be so by human scientists because they operate in the manner they do. To assert that “the laws of nature are the result of a lawmaker” is unfounded and an example of faulty logic and poor critical thinking. We have no evidentiary basis to justify any claim that a supreme intelligence decreed natural things to act in certain ways from which they are not to deviate.

If the theist goes on to claim that a supreme intelligence issued the natural laws for his own pleasure and for no reason whatsoever, then the theist is suddenly forced to admit that something exists which is not subject to any natural law, and the great chain of natural law on which the theist first based the fine-tuning argument is arbitrarily severed in order to posit the nature-independent supreme intelligence! If, on the other hand, the theist claims that there is a divine reason underlying the natural laws instantiated by the supreme intelligence – say, for example, to create the best possible universe – then logic would dictate that the Supreme Being himself is subject to a law over and above himself. Introducing the “Supreme Being” (now not-so-supreme) as an intermediary in the first place is thus rendered superfluous and unnecessary. To say that “God had a reason and purpose” in creating the universe is to posit a law external and anterior to divine edicts and thus the notion of God as an “ultimate lawgiver” suddenly dies at the hands of the theist trying to save the notion.

-------------------------------------------------------------------------------------

In order to determine whether or not the God Hypothesis is supported by evidence and able to withstand critical scrutiny, we must first construct a testable model of God. The model I have used in this essay is the God of the capital G, the personal God of classical theism that most people worship. As we have seen, the God described by classical theism can be conclusively determined not to exist. In addition the Problem of Evil and the problem of the hiddenness of God discussed above, we do not observe any of the effects that the Personal God model predicts we should see on a regular basis. In other words, the universe appears just as it should if there is no god.

But most modern-day theologians, particularly those who accept the findings of science related to the origins of the universe and of life on earth, take issue with the model of God constructed by classical theism. Many have insisted the God of classical theism is not the kind of god they believe in or write about in their sophisticated theological treatises. They embrace a different model of god, one that bears little or no resemblance to the God believed in by most non-theologians.

In Part 4 of this series, I will examine the model of god preferred and embraced by today’s scientist-theologians.
