Arnold B. Scheibel - What Makes Brains Conscious?

He would have been around 90 years old when this was made. Imagine still being that sharp of mind, articulate and inquisitive at that grand old age.

This has got to be one of my favorite videos on consciousness, thank you

This man makes the hard problem of consciousness much easier to understand. I would love to be his student.

That was my brain he was holding and it was a humbling experience indeed.

What an amazing information session, I learned so much about the questions I’ve often asked myself.

If you look at different aspects of the universe and all there is in it - including what we call consciousness - there is one thing that is present and obvious throughout. Hierarchy. From quarks to atoms to molecules to planets, stars and galaxies. But we also know from our own experience that there are different types of hierarchies. The second type of hierarchy (which isn't conceptually associated with anything materialistically tangible) is the hierarchy of consciousness - thoughts, feelings, reason, logic etc. Physical life is another hierarchy where we go from living cells, to organisms, to plants, to animals and to humans. That seems to me to be the hierarchy and it does appear that in our world the highest form of consciousness is afforded to human experience. But since consciousness has no bounds and no limitations because it cannot be measured or quantified we can safely assume that there may indeed be consciousness infinitely higher than our own. What that is or whether we can attain an even higher consciousness than that afforded to us as humans is an open question but theoretically it is possible.

Multiple tiers of feedback loops in the body and brain, maybe? Love this channel!

It'd be nice to know when all these segments were originally filmed when CTT uploads a video.

'I Am A Strange Loop', by Douglas Hofstadter, is an excellent explanation of consciousness.
