“Is this a world?” Ranger Tom asks seriously, “And if it is, am I in it?” On the lips—or fingertips—of some, this set of questions appears profound. Although I’m not technically a philosopher, I find it impossible to walk by a book with the title Why Does the World Exist? and not pick it up. I am not familiar with Jim Holt’s other work—I engage a little too heavily with books to spend much time with magazines—but the question of the title is one I’ve often pondered. It is right up there with “Why can some people get published and others can’t?” Holt is, however, on a serious quest. Not surprisingly, religion features prominently in the discussion. For the usual existential reasons, including a couple of significant deaths in the family, Holt asks perhaps the most basic of all questions and engages a number of prominent philosophers on the issue. Why is there something rather than nothing? For some in the western world such a question appears a non-starter, because our culture is biblically suffused. Whether we want to admit it or not, our social ocean veritably bobs with the basic belief that God created the world, end of story. We don’t need to ponder it, we just have to accept it. For those who look deeper, however, the answers aren’t that easy.
Holt goes through some serious computation in various forms of logic to try to arrive at a schematic demonstrating that the world is a surprising place. Not trained in such rigorous logic, I was interested to notice how the language occasionally slipped from “world” or “universe” to “reality.” Reality is perhaps the slipperiest concept of them all. Many simply accept their own experience as real, a position known as “naive realism.” Others probe somewhat deeper, seeking to verify reality. How do we know what is really real? It is, however, a different question than the existence of the world. Reality has the distinct ability to haunt with its half-answered questions and surfeit of ambiguity. Every time I wake from a dream I ask myself what is really real.
Once the divine is removed from the equation, why the world is here becomes a much more complex issue. Holt engages the new atheists as well as the neo-orthodox. It turns out that God may not help as much as we generally assume: whence God? Or, in its more childlike version, where did God come from? Once brute fact is ruled out, this becomes a tangled problem indeed. Faced with an endless regression, logic quails. Perhaps, however, we have reached the limits of rationality—even Einsteinian physics breaks down at the Big Bang. No matter what scientists or philosophers may tell us, we will always wonder, “and before that, what?” I put Holt’s book down with a sense that I’d spent a few pleasant hours considering the possibilities, but I still wonder, with Ranger Tom, if this is a world. And if it is, am I in it?
