MIT World (not the same as OpenCourseWare). And don't miss LSE, CMU, and Connexions. Still bored? Don't forget ResearchChannel, Vega, and Wikiversity. Do you care for psychology, biology, geology, or math? Or maybe you prefer journals, papers, textbooks, or podcasts? Knowledge is useful and wonderful.

Philosophy Radio and Philosophy Lectures

Among many selections are Relativism and Scepticism, Ethics and Morality ,The Origins of Value, Heidegger's Being and Time, Memes, Zombies and Human Consciousness, The Soul In Our Time and a football match between Grecian and German philosophers. We call it soccer. There's more comedy featuring a pseudointellectual cult leader beloved by privileged prep school students and college freshmen everywhere and stavrosthewonderchicken has recommended The Philosophers Drinking Song. Miguel has his picks, too. I found this while researching my I Feel Therefore I Am post yesterday and mentioned it in a comment but, heck, it deserves its own post, no?
