 Many accounts of public reason, most notably Rawls’s, recommend that we assess moral and political rules while abstaining, in several ways, from claims about truth. On Rawls’s account, for example, philosophical theories of the truth are the sort of thing over which reasonable people are assumed to disagree, and so an account of public reason cannot purport to deliver moral or political principles that are “true” according to some particular philosophical conception of truth; rather it can only deliver principles that are “reasonable” (Rawls 1996, 94). Many accounts of public reason also tell citizens that they must refrain, when engaged in public reasoning with others, from appealing to the whole truth as they see it. Regardless of what you may believe is true about religion or the good life, citizens must abstain from appeals to such truths, and instead appeal only to those public or political considerations that can be endorsed by other reasonable members of the moral or political community.
