Critics allege that justice as mutual advantage excludes vulnerable people and is thus inadequate as a conception of justice. Building on Peter Vanderschraaf’s Strategic Justice, this paper considers three distinct vulnerability objections. After Sect. 1 clarifies the “vulnerable,” Sect. 2 discusses an objection according to which it is impossible for a mutual advantage view to protect the vulnerable. Answering this objection only requires a possibility proof, such as that Vanderschraaf provides. Section 3 discusses an objection according to which it is (...) merely contingent whether, not guaranteed that, a mutual advantage view protects the vulnerable. Mutual advantage theorists indeed cannot provide such guarantees, so they must argue that such guarantees are too much to demand from a conception of justice. Section 4 discusses an objection according to which it is improbable that a mutual advantage view will protect the vulnerable. Addressing this concern opens paths for future fruitful research, including considering the conditions that make including the vulnerable more or less likely as well as the conditions that facilitate cooperative ability or create vulnerability. Section 5 builds on the foregoing by emphasizing the diversity of vulnerabilities along with the broader social contract tradition’s diversity of strategies for addressing vulnerability. (shrink)

This work aligns James Buchanan’s theory of social contract with the structure of Michael Moehler’s multilevel social contract. Most importantly, this work develops Buchanan’s notions of moral community and moral order. It identifies moral community as the vehicle of escape from moral anarchy, where community is established upon a system of rules akin to James Buchanan’s first-stage social contract. Moral order establishes the baseline treatment of non-members by members of a moral community and also provides a minimum standard for resolving (...) disputes that are not resolved by the more robust social contract shared among community members. This work links the multilevel contract to polycentric social order, noting that polycentric systems may promote development of the moral order by enabling experimentation with and emulation of rules and rule systems made available by overlapping and adjacent institutions.
