Book excerpt: Polarisation, intransigence and dogmatism in political and moral debate have in recent years threatened to overwhelm many Western-style democracies, where for centuries reasoned argument has been a hallmark feature of tackling disagreement. For many people, this marks a worrying deterioration in the moral and political climate, threatening to create a divisive environment of "us" versus "them". In this superb collection a team of international contributors examine these pressing issues from a philosophical perspective. Topics explored include: the problem of "deep disagreements"; martial conceptions of argumentation and the motivation to argue to win; epistemic egocentrism; intellectual trust; bullshit and dogmatism; intellectual humility and the internet; epistemic and "tribal" arrogance and authoritarianism; empathy and polarisation; and epistemic rights violations. Polarisation, Arrogance, and Dogmatism: Philosophical Perspectives will be of great interest to researchers in political philosophy, applied and social epistemology, ethics and feminist philosophy, as well as those working in politics and sociology.
