Abstract
For a philosopher best known for his work outside ethics and whose best‐known view about ethics is that ethics “cannot be put into words,” there is a surprising amount to say about Ludwig Wittgenstein (1889–1951) and ethics. The subject can be divided into two: Wittgenstein's ethics, and developments in ethics under Wittgenstein's influence. The subject of Wittgenstein's ethics itself subdivides into Wittgenstein's explicit writings on ethics, and the ethical significance that his work, even when not explicitly concerned with ethics, has widely been thought to bear.
