ABSTRACTCitizens in John Rawls's well-ordered society face an assurance dilemma. They wish to act justly only if they are reasonably sure their fellow citizens will also act justly. According to Rawls, this assurance problem is solved through public reasoning. This paper argues that public reason cannot serve this function. It begins by arguing that one kind of incompleteness public reason faces that most Rawlsians grant is ubiquitous but unproblematic from a normative standpoint is problematic from an assurance perspective: it makes (...) it possible for citizens to argue for policy conclusions that are favored by their private interests, rather than justice. In response, perhaps the thing to do is structure deliberative democratic institutions such that citizens will always be incentivized to use public reasons to only argue for conclusions they believe are favored by justice. The paper proves that this is impossible by extending the Gibbard–Satterthwaite theorem. (shrink)

Locke rejected anarchism. Locke defended the universal necessity of political governments on the grounds that the state of nature will occasionally generate the inconveniences of war. The standard interpretation of Locke identifies three main causes of war in the state of nature: the lack of a common judge, moral disagreement over the law of nature, and self-love. In this paper, I argue that the combination of these three factors does not guarantee that war will occur in every plausible scenarios of (...) Locke’s state of nature. Instead, in order for war to occur at least sometimes in every plausible scenario of Locke’s state of nature, there has to be some sort of epistemic deficit. In this paper, I show via the tools of modern game theory, how Locke’s state of nature may occasionally generate war by two kinds of epistemic problems implied by Locke’s own epistemology: disagreements in subjective probabilities, and uncertainty in other people’s moral motivation to use force to enforce the law of nature. The fact that war occurs primarily because of such epistemic problems suggests a role for a very limited form of government; namely, the ultra-ultra-minimal state, whose role is confined to solving such epistemic problems.
