Philosophical argument, trying to get someone to believe something whether he wants to believe it or not, is not, I have held, a nice way to behave towards someone; also it does not fit the original motivation for studying or entering philosophy. That motivation is puzzlement, curiousity, a desire to understand, not a desire to produce uniformity of belief. Most people do not want to become thought-police. The philosophical goal of explanation rather than proof not only is morally better, it is more in accord with one's philosophical motivation.
Robert NozickThrough the evolutionary process, those who are able to engage in social cooperation of various sorts do better in survival and reproduction.
Robert NozickInstead of trying to prove your opponent wrong, try to see in what sense he might be right.
Robert NozickSuppose there were an experience machine that would give you any experience you desired. Superduper neuropsychologists could stimulate your brain so that you would think and feel you were writing a great novel, or making a friend, or reading an interesting book. All the time you would be floating in a tank, with electrodes attached to your brain. Should you plug into this machine for life, preprogramming your life experiences?...Of course, while in the tank you won't know that you're there; you'll think that it's all actually happening...Would you plug in?
