While traveling to and from the Carolina head-fi meetup yesterday, I listened to the History of Philosophy Without Any Gaps podcast.
It's really great. The "Without Any Gaps" part is taken seriously*: I'm seven-ish hours and twelve episodes in already and the series is still on the Presocratics. The show is up to its 172nd weekly episode and has only gotten as far as the Medieval Eastern traditions (Arabic and Jewish philosophers and mystics). (*With the host's clearly stated caveat that he's sticking within Western and Near Eastern lineages, since East Asian history is outside his realm of expertise and would make the podcast unwieldy.)
So far this series has been gripping. Maybe it will become less so when covering subjects that are less obscure and better-documented; so far a lot of the fun has been in, for example, what has been lost to history about Zeno's paradoxes (and how they may have been intended as rhetorical openers to defend Parmenides' Monism rather than hang in the air like a koan, which is how they tend to be received these days).
The host does an excellent job of bringing life to the life of the mind. So to speak. I'm not an avid podcast listener but I'll be keeping this one on my short list of regular listens.
