People who live in states have as a rule never experienced the state of nature and vice-versa, and have no practical possibility of moving from the one to the other … On what grounds, then, do people form hypotheses about the relative merits of state and state of nature? … My contention here is that preferences for political arrangements of society are to a large extent produced by these very arrangements, so that political institutions are either addictive like some drugs, or allergy-inducing like some others, or both, for they may be one thing for some people and the other for others.
