Human beings prosper through cooperation. Compulsion is not cooperation. People must be free to cooperate.

With freedom comes responsibility – to accept the consequences of our choices, and to respect and protect each others' freedom. Not everyone will respect that responsibility voluntarily. Freedom without mutual responsibility is the law of the jungle. The role of government is (with the minimum of coercion, intrusion and cost) to define and enforce the rules and responsibilities that maximize freedom and cooperation.

Much follows from this. It is just the start and basis of the philosophy. But already we have introduced some terms, like freedom, that mean different things to different people. We will expand on the philosophy through examination of the meanings of certain key terms.
