John McCarthy

Here's a way to tell scientific intelligence from legal intelligence. Both may start from the idea that something cannot be done and think up arguments to explain why. However, it is possible that the scientist may discover a flaw in the argument that leads him to change his mind and discover a way to do it. He will be pleased. The legal thinker will merely try to patch the flaw in the argument, because once he has chosen a side, all his intelligence is devoted to finding arguments for that side.
