Christopher Hitchens - The Portable Atheist - Essential Readings for the Nonbeliever

Whether or not you will buy into my account of the origin of physical law, I hope you will allow that I have at minimum provided a plausible natural scenario for a gap in scientific knowledge, that gap being a clear consensus on the origin of physical law. Once again, I do not have the burden of proving this scenario. The believer who wishes to argue that God is the source of physical law has the burden of proving (1) that my account is wrong, (2) that no other natural account is possible, and (3) that God did it.

Why Is There Something Rather Than Nothing?

If the laws of physics follow naturally from empty space-time, then where did that empty space-time come from? Why is there something rather than nothing? This question is often the last recourse of the theist who seeks to argue for the existence of God from physics and cosmology and finds that all his other arguments fail. Philosopher Bede Rundle calls it “philosophy’s central, and most perplexing, question.” His simple (but book-length) answer: “There has to be something.” [59] 28. Bede Rundle, Why There Is Something Rather Than Nothing (Oxford: Clarendon Press, 2004).

Clearly many conceptual problems are associated with this question. How do we define “nothing”? What are its properties? If it has properties, doesn’t that make it something? The theist claims that God is the answer. But, then, why is there God rather than nothing? Assuming we can define “nothing,” why should nothing be a more natural state of affairs than something? In fact, we can give a plausible scientific reason based on our best current knowledge of physics and cosmology that something is more natural than nothing!

In Chapter 2 we saw how nature is capable of building complex structures by processes of self-organization, how simplicity begets complexity. Consider the example of the snowflake, the beautiful six-pointed pattern of ice crystals that results from the direct freezing of water vapor in the atmosphere. Our experience tells us that a snowflake is very ephemeral, melting quickly into drops of liquid water that exhibit far less structure. But that is only because we live in a relatively high-temperature environment, where heat reduces the fragile arrangement of crystals to a simpler liquid. Energy is required to break the symmetry of a snowflake.

In an environment where the ambient temperature is well below the melting point of ice, as it is in most of the universe far from the highly localized effects of stellar heating, any water vapor would readily crystallize into complex, asymmetric structures. Snowflakes would be eternal, or at least would remain intact until cosmic rays tore them apart.

This example illustrates that many simple systems of particles are unstable, that is, have limited lifetimes as they undergo spontaneous phase transitions to more complex structures of lower energy. Since “nothing” is as simple as it gets, we cannot expect it to be very stable. It would likely undergo a spontaneous phase transition to something more complicated, like a universe containing matter. The transition of nothing-to-something is a natural one, not requiring any agent. As Nobel laureate physicist Frank Wilczek has put it, “The answer to the ancient question ‘Why is there something rather than nothing?’ would then be that ‘nothing’ is unstable.” [60] 29. Frank Wilczek, “The Cosmic Asymmetry Between Matter and Antimatter,” Scientific American 243, no. 6 (1980): 82–90.

In the nonboundary scenario for the natural origin of the universe I mentioned earlier, the probability for there being something rather than nothing actually can be calculated; it is over 60 percent. [61] 30. Stenger, The Comprehensible Cosmos , supplement H.

In short, the 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.

Any atheist in any argument with the religious will soon find that many, if not most, “believers” are choosing á la carte from an infinite menu of possible affirmations. We wish them luck, even as we wish that they could make their incoherent beliefs consistent. With great generosity, Daniel Dennett suggests that “belief in belief” is at the root of all this, and that people really would rather assert some vague faith than none at all. He even concedes that this may sometimes have been helpful. However, he inquires politely whether people who talk in this fashion can possibly mean what they appear to say.

Philosophers stretch the meaning of words until they retainscarcely anything of their original sense; by calling “God” somevague abstraction which they have created for themselves, theypose as deists, as believers, before the world; they may even pridethemselves on having attained a higher and purer idea of God,although their God is nothing but an insubstantial shadow andno longer the mighty personality of religious doctrine.

How do I define religion? It doesn’t matter just how I define it, since I plan to examine and discuss the neighboring phenomena that (probably) aren’t religions—spirituality, commitment to secular organizations, fanatical devotion to ethnic groups (or sports teams), superstition…. So, wherever I “draw the line,” I’ll be going over the line in any case. As you will see, what we usually call religions are composed of a variety of quite different phenomena, arising from different circumstances and having different implications, forming a loose family of phenomena, not a “natural kind” like a chemical element or a species.

What is the essence of religion? This question should be considered askance. Even if there is a deep and important affinity between many or even most of the world’s religions, there are sure to be variants that share some typical features while lacking one or another “essential” feature. As evolutionary biology advanced during the last century, we gradually came to appreciate the deep reasons for grouping living things the way we do—sponges are animals, and birds are more closely related to dinosaurs than frogs are—and new surprises are still being discovered every year. So we should expect—and tolerate—some difficulty in arriving at a counterexample-proof definition of something as diverse and complex as religion. Sharks and dolphins look very much alike and behave in many similar ways, but they are not the same sort of thing at all. Perhaps, once we understand the whole field better, we will see that Buddhism and Islam, for all their similarities, deserve to be considered two entirely different species of cultural phenomenon. We can start with common sense and tradition and consider them both to be religions, but we shouldn’t blind ourselves to the prospect that our initial sorting may have to be adjusted as we learn more. Why is suckling one’s young more fundamental than living in the ocean ? Why is having a backbone more fundamental than having wings ? It may be obvious now, but it wasn’t obvious at the dawn of biology.

In the United Kingdom, the law regarding cruelty to animals draws an important moral line at whether the animal is a vertebrate: as far as the law is concerned, you may do what you like to a live worm or fly or shrimp, but not to a live bird or frog or mouse. It’s a pretty good place to draw the line, but laws can be amended, and this one was. Cephalopods—octopus, squid, cuttlefish—were recently made honorary vertebrates, in effect, because they, unlike their close mollusc cousins the clams and oysters, have such strikingly sophisticated nervous systems. This seems to me a wise political adjustment, since the similarities that mattered to the law and morality didn’t line up perfectly with the deep principles of biology.
