At the core of political liberalism is the claim that political institutions must be publicly justified or justifiable to be legitimate. What explains the significance of public justification? The main argument that defenders of political liberalism present is an argument from disagreement: the irreducible pluralism that is characteristic of democratic societies requires a mode of justification that lies in between a narrowly political solution based on actual acceptance and a traditional moral solution based on justification from the third-person perspective. But why should we take disagreements seriously? This – epistemic question – has not received the attention it deserves so far. I argue that the significance of public justification can be explained through the possibility of reasonable disagreement. In a reasonable disagreement, the parties hold mutually incompatible beliefs, but each is justified to hold the belief they do. I shall use the notion of a reasonable disagreement to explain the possibility of an irreducible pluralism of moral and religious doctrines and, on that basis, why the justification of political institutions has to be public.

This book offers a systematic treatment of the requirements of democratic legitimacy. It argues that democratic procedures are essential for political legitimacy because of the need to respect value pluralism and because of the learning process that democratic decision-making enables. It proposes a framework for distinguishing among the different ways in which the requirements of democratic legitimacy have been interpreted. Peter then uses this framework to identify and defend what appears as the most plausible conception of democratic legitimacy. According to this conception, democratic legitimacy requires that the decision-making process satisfies certain conditions of political and epistemic fairness.

Collective deliberation is fuelled by disagreements and its epistemic value depends, inter alia, on how the participants respond to each other in disagreements. I use this accountability thesis to argue that deliberation may be valued not just instrumentally but also for its procedural features. The instrumental epistemic value of deliberation depends on whether it leads to more or less accurate beliefs among the participants. The procedural epistemic value of deliberation hinges on the relationships of mutual accountability that characterize appropriately conducted deliberation. I will argue that it only comes into view from the second-person standpoint. I shall explain what the second-person standpoint in the epistemic context entails and how it compares to Stephen Darwall’s interpretation of the second-person standpoint in ethics

There is consistent and strong empirical evidence for social inequalities in health, as a vast and fast growing literature shows. In recent years, these findings have helped to move health equity high on international research and policy agendas. This paper examines how the empirical identification of social inequalities in health relates to a normative judgment about health inequities and puts forward an approach which embeds the pursuit of health equity within the general pursuit of social justice. It defends an indirect approach to health equity, which views social inequalities in health as unjust in so far as they are the result of an unjust basic structure of society in Rawls’ sense.

Does political decision-making require experts or can a democracy be trusted to make correct decisions? This question has a long-standing tradition in political philosophy, going back at least to Plato’s Republic. Critics of democracy tend to argue that democracy cannot be trusted in this way while advocates tend to argue that it can. Both camps agree that it is the epistemic quality of the outcomes of political decision-making processes that underpins the legitimacy of political institutions. In recent political philosophy, epistemic democrats have embraced this instrumentalist way of thinking about democracy. In this chapter, I argue that the attempt to defend democracy on epistemic instrumentalist grounds is self-undermining. I also develop an alternative – procedural – epistemic defence of democracy. I show that there is a prima facie epistemic case for democracy when there is no procedure-independent epistemic authority on the issue to be decided.
