Abstract

On Moral Certainty, Justification and Practice presents a view of morality that is inspired by the later Wittgenstein. Hermann explores the ethical implications of Wittgenstein's remarks on doubt, justification, rule-following, certainty and training, offering an alternative to interpretations of Wittgenstein's work that view it as being intrinsically ethical. The book scrutinises cases in which doubt and justification do not make sense, and contrasts certain justificatory demands made by philosophers with the role of moral justification in concrete situations. It offers an account of moral certainty, which is linked to a view of moral competence. Contrary to the views propounded by philosophers who emphasise the importance of moral principles, it is argued that moral agency is first and foremost a matter of having certain capacities. The book takes an anti-intellectualist stance and remains close to concrete practices. The practice-based view of morality it endorses has implications for moral education, intercultural moral dialogue and the prospects for moral agreement, change and progress.
