Abstract

In the Tractatus Logico-Philosophicus we find Wittgenstein’s first and most substantial published investigation of ethics. I will argue that if the ethical sections of the Tractatus are seen in connection with a particular concept of showing, they then reveal a coherent and radical alternative to traditional conceptions of ethics; an alternative which sheds light on Wittgenstein’s claim that ethics cannot be expressed and the necessity of ethics. But I furthermore want to argue that the reasons leading Wittgenstein to a demand for silence in ethics falls away if one looks at the later investigations of necessity which he makes in On Certainty
