subject: Is A Brain A Computer? [print this page] I personally would have to conclude (and feel free to differ) that the brain is much more than the sum of its parts, while the computer is not in the slightest. It is consciousness that makes us human, and what role exactly the brain plays in that metaphysical mystery is not known. I do not believe on the other hand that computers have any sort of consciousness whatsoever. The human is a tool making creature and the computer is the greatest tool he has ever made. That, I believe anyway, is as far as it goes.
