Freudianism may no longer be in vogue. But, even so, Sigmund Freud remains one of the most envelope-pushing thinkers of the past century, someone still worth getting to know. In this lecture, Yale psychology professor Paul Bloom offers a primer on Freud and Freudian thought. The lecture is part of a larger free course (20 lectures in total) called "Introduction to Psychology." You can access the course via the Yale Open Course web site, YouTube and iTunesU.
