I have seen some of these lectures, thank you for reminding me----It's really good because you can see and choose the class, the professor etc----lots to learn: A while ago I watched one on the Transcendentalists (I was reading a bio of LM Alcott at the time and realized I hadn't read that whole group in years, the lectures were very helpful)---Also started, and want to finish one on evolution that was quite good. This is something to put on my "do it once a week" (at least) list. Thanks again.
