Each community must win and hold the voluntary adherence of its members.

Quotes from the same author

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.

Our main conclusions about the state are that a minimal state, limited, to the narrow functions of protection against force, theft, fraud, enforcement of contracts, and so on, is justified, but any more extensive state will violate persons' rights not to be forced to do certain things, and is unjustified; and that the minimal state is inspiring as well as right.
