Crash Course has this relatively new video on Pascal’s Wager, and it’s a good one for IB Theory of Knowledge classes.
My big critique of it, though, is the same one I have for all of Crash Course’s videos – he’s speaks so darn fast. Proficient English speakers should be able to get it, but English Language Learners (and I have many in my TOK course) are going to find it tough to access:
You might put this video into a tool like Vialogues.com and then annotate it with questions, notes, and such. Then anyone could use it. Or do it again with a fresh set of eyes.
