This Element is the study of Wittgenstein's view of ethics in Tractatus and surveys of later investigations of ethics.

In Ludwig Wittgenstein's writings, ethics takes a central place in his thinking. This element investigates his engagement with ethics in both early and later thinking. Starting from the remarks on ethics in the Tractatus Logico-Philosophicus and the framing of these remarks, it presents two influential approaches to Tractarian ethics, before it develops a coherent reading of ethics in the early thinking, focusing on ethical silence and the relationship notions of world and the philosophical 'I'. The reading of 'A Lecture on Ethics' focuses on the critique of ethical theory and the personal dimension of ethics, two themes also running through Wittgenstein's later thinking. It considers Wittgenstein's later ethical investigations, of ethical examples, ethically relevant language uses of language and the connections between reflections on ethics and living. It also considers the role of the other in Wittgenstein's later thinking.
