Discussions of why corporations should cultivate a diverse workforce emphasize justice- and profit-based reasons. This paper defends a distinct third rationale of legitimacy-based reasons for diversity. I articulate and defend the _market power account_ of firm legitimacy, which holds that private firms, much like governmental institutions, have a moral obligation to justify the power they exercise over stakeholder groups when those groups lack meaningful rights of exit from their relationship with the firm. Firms can discharge this obligation by incorporating _moral (...) diversity_ into managerial teams that decide company policy. Moral diversity confers both epistemic and moral advantages onto teams tasked with solving complex problems that impact disparate stakeholder groups. These advantages confer proceduralist legitimacy onto implemented policies, giving impacted groups reason to accept those policies, even when those groups find those policies objectionable on other grounds.

Michael Moehler’s Minimal Morality is a wonderful and important book, from which I have learned a great deal. It reinvigorates rational choice moral theory in the process of confronting what I see as the most important issue in social and moral philosophy today: can those in a deeply morally divided society endorse a common moral framework to structure social cooperation? Is a rational moral order possible under conditions of deep and wide moral diversity? Minimal Morality’s answers are thoughtful and innovative. (...) I am not, however, entirely persuaded that Minimal Morality can fulfil its promise of grounding a cooperative order when ‘traditional’ modes moral justification cannot. (shrink)

The topic of moral diversity is not only prevalent in contemporary moral and political philosophy, it is also practically relevant. Moral diversity, however, poses a significant challenge for moral theory building. John Thrasher, in his discussion of public reason theory, which includes social contract theory, argues that if one seriously considers the goal of moral constructivism and considerations of representation and stability, then moral diversity poses an insurmountable problem for most public reason theories. I agree with Thrasher that moral diversity (...) poses a significant challenge for orthodox multistage social contract theories. In fact, I even add a further problem for such theories under the assumption of deep moral diversity. Nevertheless, I argue that my recently developed multilevel social contract theory overcomes these problems. I focus on some of the underexplored features of this theory to show that multilevel social contract theory offers one conceptually coherent and plausible way to render social contract theory viable and relevant for modern diverse societies.

This paper considers contractarianism as a method of justification. The analysis accepts the key tenets of contractarianism: expected utility maximization, unanimity as the criteria of acceptance, and social-scientific uncertainty of modelled agents. In addition to these three features, however, the analysis introduces a fourth feature: a criteria of rational belief formation, viz. Bayesian belief updating. Using a formal model, this paper identifies a decisive objection to contractarian justification. Insofar as contractarian projects approximate the Agreement Model, therefore, they fail to justify (...) their conclusions. Insofar as they fail to approximate the Agreement Model, they must explain which modelling assumption they reject. (shrink)

Conventionalism as a distinct approach to the social contract received significant attention in the game-theoretic literature on social contract theory. Peter Vanderschraaf’s sophisticated and innovative theory of conventional justice represents the most recent contribution to this tradition and, in many ways, can be viewed as a culmination of this tradition. In this article, I focus primarily on Vanderschraaf’s defense of the egalitarian bargaining solution as a principle of justice. I argue that one particular formal feature of this bargaining solution, the (...) baseline consistency requirement, may stand in tension with other features of conventionalism as an approach to the social contract and limit the scope of Vanderschraaf’s theory to societies in which de facto an egalitarian sense of justice evolves. It limits the scope of Vanderschraaf’s theory in the face of moral diversity. A similar limitation applies to Vanderschraaf’s theory of democratic political authority. Despite these minor limitations, Vanderschraaf’s theory can only be seen as a major success and significant contribution to social contract theory. (shrink)
