causalityThe connection between cause and effect: necessary structure of the world, contingent habit of the mind, or something the mind supplies.Discussed in 6 lectures across 3 courses ↗︎
The ApologyPlato's account of Socrates' trial and death sentence, the founding scene of philosophy as a way of life.Discussed in 6 lectures across 3 courses ↗︎
