The Substance Argument of Wittgenstein’s Tractatus

  • Michael Morris University of Sussex


In Morris (2008) I presented in outline a new interpretation of the famous ‘substance argument’ in Wittgenstein’s Tractatus (Wittgenstein 1922). The account I presented there gave a distinctive view of Wittgenstein’s main concerns in the argument, but did not explain in detail how the argument works: how its steps are to be found in the text, and how it concludes. I remain convinced that the interpretation I proposed correctly identifies the main concerns which lie behind the argument. I return to the argument here in order to elaborate in fuller detail the relation between those concerns and the actual course of the text.
