 An alternative way of justifying democracy on the basis of equality is to ground democracy in public equality. Public equality is a principle of equality which ensures that people can see that they are being treated as equals. This view arises from three ideas. First, there is the basic egalitarian idea that people’s interests ought to be equally advanced, or at least that they ought to have equal opportunities to advance them. Second, human beings generally have highly fallible and biased understandings of their own and other people’s interests. Third, persons have fundamental interests in being able to see that they are being treated as equals. Public equality is an egalitarian principle that can be seen to be realized among persons despite the dramatically incomplete forms of knowledge people have. It is not all of justice, but it is essential that the principle be realized in a pluralistic society.
