Robert NozickPhilosophical 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.
