The Enduring Conundrum of Consciousness

This is a subject I imagine every adult and probably teenager has contemplated, more than once and for considerable periods of time. It's an older video, and about 1.5 hours long, but for anyone seriously interested in the subject--and who isn't?--I think it gives much food for thought. Delightful speakers, good moderator, issues you've likely never considered. Some parts go pretty fast, but they are clearly understandable. "Food for thought," to put it mildly.
