How Do You Explain Consciousness? - David Chalmers
'Our consciousness is a fundamental aspect of our existence, says philosopher David Chalmers: "There's nothing we know about more directly.... but at the same time it's the most mysterious phenomenon in the universe." He shares some ways to think about the movie playing in our heads.
The hard problem of consciousness is the problem of explaining how we experience qualia or phenomenal experiences, such as seeing, hearing, and feeling, and knowing what they are." from the video introduction
