Episode notes

In a paradox similar to Newcom's, it's you who has some information about the future. So your personal future is the universe. You know that your grandfather will have kids and you have evidence of it. Do we learn any lessons philosophically from this case? I completely agree with your conclusion there.

Is metaphysics like physics, but cooler? Or is it a relic of an outdated, pre-empirical way of thinking about the world? Closer to the former than the latter. Rather than building specific quantitative theories about the world, metaphysics aims to get a handle on the basic logical structures that help us think about it. I talk with philosopher Katie Elliott on how metaphysics helps us think about questions like counterfactuals, possible worlds, time travel, mathematical equivalence, and whether everything happens for a reason.
