 One reason that reasonable citizens are so tolerant, Rawls says, is that they accept a certain explanation for the diversity of worldviews in their society. Reasonable citizens accept the burdens of judgment. The deepest questions of religion, philosophy, and morality are very difficult to think through. Even conscientious people will answer these questions in different ways, because of their particular life experiences (their upbringing, class, occupation, and so on). Reasonable citizens understand that these deep issues are ones on which people of good will can disagree, and so will be unwilling to impose their own worldviews on those who have reached conclusions different than their own.
