(few others have thought more powerfully and deeply about these matters), that Hobbes "created" political hedonism, which transformed life "on a scale never yet approached by any other teaching."*26 It is a not very important detail that instead of pleasure (as hedonists are supposed to seek), Hobbes spoke of self-preservation as the end which explains action.*27 Since Hobbes, it is tacitly treated as a self-evident truth that people need, or want to have, the state because their hedonistic pain-and-pleasure calculus is ipso facto favourable to it.
1.5.21 Recent research into the prisoners' dilemma, both deductive into its logical structure and experimental into actual behaviour in such situations, has established that acceptance of coercion by the participants is not a necessary condition for their finding a "cooperative solution."*28 Some of the crucial steps toward getting this result are: (a) to admit that the dilemma can be confronted more than once (it can be an iterative or sequential "game"), so that reliance on single-stage rationality may not correctly predict the moves of rational players; (b) to make a player's move depend in part on the other player's move in a previous stage of the sequential game, or in some other game altogether (i.e. to make it depend on experience), either player taking account of the reputation established by the other for toughness or softness; (c) to make him play as he ought to if the other player were playing tit-for-tat; (d) to introduce some regard for the relative value of present and future; and (e) to let the increased pay-off of a cooperatively solved game teach people to go for the cooperative solution in subsequent games. It is intuitively plausible that in a state of nature where people do not instantly club each other to death in a single-stage noncooperative performance of the dilemma game, but where they survive for some time and have both occasion and incentive to assess and heed each other's capacity for retaliation, vengefulness, mutual protection, gratitude, fair play, etc. the prisoners' dilemma becomes both very much more complicated and loses much of its inexorability.
Nor need one limit the application of this result to the sole bellum omnium contra omnes. Hobbes makes people choose Leviathan to produce order out of purported chaos. But people need not have chosen Leviathan, since some kind of cooperative solution, some kind of order emerges in the state of nature, too, though it may not be the same kind of order as that produced by the state. Both qualitative and quantitative differences are possible, indeed extremely likely, though it is very hard to form sensible hypotheses about what the voluntary solution would exactly be like. Whether the voluntary product, in turn, is inferior or superior to the state product, will have to remain a matter of taste. The important thing is not to confuse the question of how we like either product, with the far more vital question of how we like the entire society in which order is state-produced, compared to the entire society (the state of nature) in which it is a voluntary arrangement.
What goes for order goes, by simple extension of the argument, for other public goods as well, whose production was supposed to have been altogether prevented by a rigidly interpreted prisoners' dilemma and the related, rather looser free-rider problem.*29 Once a public good, say clean air, paved streets or national defence, gets produced, people cannot be excluded from enjoying it regardless of whether they have paid their share of the cost of producing it. (We shall have occasion in chapter 4, pp. 234-6, to question what "their share," in the sense of the part of the cost that a particular person ought to bear, can possibly mean.) Therefore, many will choose not to bear "their share" and the public good will not get produced or maintained, unless the state steps in to coerce all would-be free riders to pay, at the one hit both
