An important objection to political liberalism is that it provides no means by which to decide conflicts between public and non-public reasons. This article develops John Rawls' idea of `reasoning from conjecture' as one way to argue for a commitment to public reason. Reasoning from conjecture is a form of non-public justification that allows political liberals to reason from within the comprehensive views of at least some unreasonable citizens. After laying out the basic features of this form of non-public justification, (...) this article responds to three objections based on concerns about insincerity, cultural imperialism, and the epistemic authority of those who reason from conjecture.

A common objection to the idea of public reason is that it cannot resolve fundamental political issues because it excludes too many moral considerations from the political domain. Following an important but often overlooked distinction drawn by Gerald Gaus, there are two ways to understand this objection. First, public reason is often said to be inconclusive because it fails to generate agreement on fundamental political issues. Second, and more radically, some critics have claimed that public reason is indeterminate because it (...) cannot provide any citizen with sufficient reason(s) for making important political decisions. Against the first of these objections, I argue that the purpose of public reason is not to end reasonable disagreement. Rather, it is to provide a suitable framework of values and principles within which citizens may resolve their moral and political differences. Against the second objection, I argue, first, that the indeterminacy of public reason is much less common than its inconclusiveness; and, second, that there are second-order decision-making strategies that may enable citizens to cope with cases of indeterminacy. The incompleteness of public reason, whether it takes the form of inconclusiveness or indeterminacy, is not a reason for citizens to abandon their commitment to public justification. (shrink)

In Speech Matters, Seana Shiffrin claims that certain lies should be tolerated on grounds of political inclusiveness. If political equality requires perfect compliance with fair terms of social cooperation, and if lying violates those terms, then liars might be at risk of losing their standing as political equals. To avoid that draconian result requires accommodation of moral imperfections, including some lies. In response, I argue that Shiffrin’s view may have broader implications for requirements of sincerity under non-ideal political conditions. In (...) some circumstances, where there is widespread defection from fair terms of cooperation, lying might be a moral but not a political wrong. (shrink)

John Locke's theory of toleration has been criticized as having little relevance for politics today because it rests on controversial theological foundations. Although there have been some recent attempts to develop secular; or publicly accessible, arguments out of Locke's writings, these tend to obscure and distort the religious arguments that Locke used to defend toleration. More importantly, these efforts ignore the role that religious arguments may play in supporting the development of a normative consensus on the legitimacy of liberal political (...) principles. Bracketing the search for publicly accessible justifications makes it possible to appreciate the continued relevance of Locke's religious arguments for toleration. (shrink)
