I used to make polyhedra with my father. There were no clear lines between games and toys for children and his professional work.

— Roger Penrose

It may well be there is something else going on in the brain that we don't have an inkling of at the moment.

— Roger Penrose

It is hard to see how one could begin to develop a quantum-theoretical description of brain action when one might well have to regard…

A computational device is incapable of developing a mind. We got consciousness not just by being clever.

My father himself was a human geneticist who was recognized for demonstrating that older mothers tend to get more Down syndrome children, but he…
