Why Do We Find Things Beautiful?

Here's a thought that kept me up: beauty is suspiciously useful. A ripe fruit, a clear stream, a symmetrical face, a sweeping vista with somewhere to hide and something to eat — we find these things lovely, and they also happen to be good for us.

Neuroscience tells us that aesthetic pleasure lights up reward circuitry, the same machinery that nudges us toward food and connection. Evolution, meanwhile, rarely builds expensive feelings for no reason.

So maybe beauty is a heuristic — a fast, fuzzy signal pointing at things that tended to keep our ancestors alive. Which is a romantic thought wrapped in a cynical one, or possibly the other way around.

I don't have a tidy answer, and I've made peace with that. Some curiosities are more fun to keep open than to close.
