The Principal Activities Of Brains Are Making

All Intelligent Problem Solvers Are Subject To The Same Ultimate Constraints - Limitations On Space, Time, And Materials.

Minds Are Simply What Brains Do.

Logic Doesn't Apply To The Real World. D. R. Hofstadter And D. C. Dennett (eds.) The Mind's I, 1981.

To Say That The Universe Exists Is Silly, Because It Says That The Universe Is One Of The Things In The Universe. So There's Something Wrong With Questions Like, "what Caused The Universe To Exist?"

But The Big Feature Of Human-level Intelligence Is Not What It Does When It Is Works But What It Does When It's Stuck.
