What is the ethical basis for democracy? What reasons do we have to go along with democratic decisions even when we disagree with them? When can we justly ignore democratic decisions? These three questions are intimately connected: understanding what is ultimately important about democracy helps us to understand the authority of democratic decisions over our personal views, and the limits of such authority.

The book then aims to show how both democracy and basic liberal rights are grounded in the principle of public equality, which tells us that in the establishment of law and policy we must treat persons as equals in ways that they can see are treating them as equals (Chaps. 3 and 4).
