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?
