Over years of teaching philosophy, I have observed that people fall into two groups with regard to the Biggest Question. The Biggest Question is one that is so big it is hard to fit into words, but here goes: When everything that can be explained has been explained, when we know the truths of physics and brains and psychology and social interactions and so on and so forth, will there still be anything worth wondering about? I am assuming the “wonder” here is a philosophical wonder, not the sort of wonder over whatever happened to my old pocket knife or whatever. It’s the sort of wonder that has a “why-is-there-something-rather-than-nothing” flavor to it. It’s the sort of wonder that doesn’t go away no matter how much is explained.
Some people think that on that sunny day when everything that can be explained has been explained, well then, that will be that. We will understand why things have happened, and how we came to exist, and what we should do if we want to be healthy and happy, and why works of art move us as they do. It’s not that such people are in any way shallow or unimaginative or tone deaf. They are open to the most wonderful experiences of life, along with the most heart-wrenching and most tragic. It’s just that they think these experiences can be explained and understood in all their glory through that explanation. If there is anything “left over” — some stubborn bit of incredulous wonder we just can’t shake — then that too will be explained through some feature of human psychology, like the way those patterns still seem to swirl in a static optical illusion even when you know the trickery behind it. The feeling that there is a Mystery can itself be explained as an illusory sort of feeling, an accidental by-product of the cognitive engine we happen to think with.
