David K. Lewis

I think Descartes' Meditations on First Philosophy, it's pretty short, crazy thought experiments, almost matrix-like, is a really good way to see if you care about philosophy or not.

And if you find out that you do care, then one of my favorite philosophers is David Lewis, and his book On the Plurality of Worlds is a fantastic book, so people should

read it.

Okay, good.

Modern philosophers have a phrase for this.

They call it modal realism, and the strongest version was pushed by a twentieth century American philosopher named David Lewis, who argued that every possibility is, in some sense, real.

That the space of possibilities is the deepest layer there is.

That every way the world could be is somewhere, and the actuality you happen to live in is simply one of the ways.

But the laws, and the laws may depend on how, what is in these dimensions, is laid out in these dimensions.

There's a philosopher, D.C. Williams, anybody know him? He's a very important guy who almost nobody reads about now, but his influence is enormous via David Lewis.

And to some extent, a little bit, I've written about him and other people I know have written about him.

But he's the view that I'm just sort of describing.
