I listened to a lecture by Pierre Grimes a while back and have since tracked him down again after it popped back into my head the other day. There are a number of youtube lectures in front of an inquisitive classroom, given at the Noetic Society, which are incredibly intense and instructive on a wide array of philosophy subjects. Check out these youtube channels for videos :
PostNothingness / Pierre Grimes and the Noetic Society
The following lecture I just watched mainly on Parmenides has a lot of wild moments regarding the philosophy of time and the nature of reality. In addition to giving an overview of the philosophers ideas, Pierre gives knowledgeble context to these thinkers recaptured from the dominant narrative, which often downplays the significance of individual thinkers in their own right.
