 These two ways in which public reason limits appeals to truth generate several distinct objections. First, some worry that if a system of moral or political justification ignores the whole truth, the resulting moral or political principles may be false. For example, if it is true that all sinners will go to hell when they die, but we are precluded from appealing to this truth in developing our political principles, we may endorse a political principle that permits people to engage in various sinful activities. If we could appeal to the whole truth about hell, however, we would see that this political principle is false. Others worry that without some appeal to truth, any agreement on political principles will amount to a mere modus vivendi (Hampton 1989, 806–07). A related worry—that precluding the appeal to certain truths will render us unable to solve certain problems—is considered in section 7.3 below.
