Came here to suggest Robert Sapolsky's class as well.
I would also add Michael Sandel's Justice: What's the right thing to do? https://www.youtube.com/watch?v=kBdfcR-8hEY&list=PL15D875D84... great course on moral reasoning, covers different theories of justice based on ideas from Aristotle, Kant, John Stuart Mill, John Rawls and many more, extremely well presented too.
