John McCarthy has a good sense of humor
Q. Can computers know? A. This is largely a question of definition. If a camera looked at a table, we could say it "knows" that there are four containers of liquid on the table (which was true). Q. Is there any definition of "know" in which computers cannot succeed? A. Well, I suppose the biblical sense. Q. Ha, well, what makes you think that? A. They don't satisfy the necessary axioms (laughter)
