Political philosophy relies on three alternative types of theory to explain social order. The first, is order anarchy, built on the system of spontaneous Humean conventions. They are equilibria, self-enforcing or enforced by the participants’ own contingent strategies and involve no central,...

The article systematically explores the compatibility of Hume’s political philosophy and contractarianism by reconstructing Hume’s criticism of the idea of a social contract. In a nutshell, the dispute concerns the theoretical reconstruction of the establishment and maintenance of normative...

Sen’s critique of the homo economicus conception of choice asserts that agents who ‘displace’ their goals, and instead choose on the basis of others’, are not therefore irrational. I first defend Sen against the objection that violations of “self-goal choice” undermine coherent...

I begin with two simple, similar interactions. In one, maximizing agents will reach a Pareto-optimal equilibrium, in the other, they won’t. The first shows the working of the Invisible Hand; the second, its limitations. Using other simple interactions in which equilibrium and P-optimality are...

Social contract theory is incoherent and it does not work as desired. Among the most obvious disanalogies is that contracts are enforced by a third party, commonly the state. There is no such external enforcer for a constitution. Contractarian theorists typically ignore all such issues and use...

The article focuses on the justification provided by classical contract theory for the right of states to enact laws and the corresponding obligation of political allegiance. At first the distinction between political authority and parental authority developed by John Locke in his seminal work...

In this essay I argue that one can understand the relationship between those who rule and those who are ruled in civil society as an implicit contractual relationship or contract by convention. I use variations of the extensive form Trust Game to summarize the structures of alternative forms of...

The recent renaissance of work on conventions, informal institutions, and social norms has reminded us that between the state and individual choice is a network of informal social rules that are the foundation of our cooperative social life. However, even those who appreciate the importance of...

I argue that social-contract theory cannot succeed because reasonable people may always disagree, and that social-contract theory is irrelevant to the problem of the legitimacy of a form of government or of a system of moral rules. I note the weakness of the appeal to implicit agreement, the...
