And this is a painting done much, much later of what that death of Socrates might have looked like. But you see here Socrates about to, or maybe he just drank the hemlock, which is the poison, which will kill him. So even though he had to die for these pretty spurious allegations, his legacy lives on. And it lives on most famously in his student Plato. Now Plato is famous for many things. There's this notion of a platonic ideal form that whether you're talking about a circle or a ball or a dog or a chair, that there's an ideal form that is independent of what your senses are telling you or what the chair in front of you might be.
