#substance-dualism

A few years ago, I climbed over a gate and found myself gazing down at a valley. After I'd been walking for a few minutes, looking at the fields and the sky, there was a shift in my perception. Everything around me became intensely real. The fields and the bushes and trees and the clouds seemed more vivid, more intricate and beautiful.

Many philosophers strike me as like Polish apparatchiks in 1983-they turn up to work and do what they did yesterday just because they don't know what else to do, not because they seriously believe in the system they are maintaining. I think it's not been fully appreciated how much of a blow it is to the confidence of the field's youth that scientific ambitions are increasingly abandoned as untenable.

For Plato, psyche meant something like what we'd now call mind -understood as a complex system requiring governance. The psyche had distinct parts: a reasoning part that deliberates, a spirited part that feels emotion and courage, and an appetitive part that desires. Each part has its own function and its own form of excellence. And crucially, these parts need to be governed-integrated under what Plato called constitutional self-rule.

A drawn circle is at least something physical. You can see it, touch it, erase it. The skeptic can still say, "Circles are grounded in physical reality. Justice is different; it's just an idea in your head." So let's talk about the number two. Point to it. Not two apples, not two fingers, not a numeral on a page-that's just a symbol.
