The terminology of philosophical art is coercive: arguments are powerful and best when they are knockdown, arguments force you to a conclusion, if you believe the premisses you have to or must believe the conclusion, some arguments do not carry much punch, and so forth. A philosophical argument is an attempt to get someone to believe something, whether he wants to beleive it or not. A successful philosophical argument, a strong argument, forces someone to a belief.
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.
Robert NozickTaxation of earnings from labor is on a par with forced labor. Seizing the results of someone's labor is equivalent to seizing hours from him and directing him to carry on various activities.
Robert NozickThe illegitimate use of a state by economic interests for their own ends is based upon a preexisting illegitimate power of the state to enrich some persons at the expense of others. Eliminate that illegitimate power of giving differential economic benefits and you eliminate or drastically restrict the motive for wanting political influence.
