Leonard Peikoff

This is the second part of a two-part, 24-lecture course on the history of Western philosophy taught by philosopher Leonard Peikoff. This first part starts with the pre-Socratic Greeks and ends with the Enlightenment thinker David Hume. This course is intended for non-experts, but philosophy students should find much value in Peikoff’s presentation as well.
