Taking inspiration from the later Wittgenstein, On Moral Certainty, Justification and Practice explores the practical basis of human morality. It offers an account of moral certainty, which it links with a view of moral competence. Drawing on everyday examples, it is shown how morality is grounded in action, not in reasoning.
