ABSTRACT
Wittgenstein’s point here, and throughout the Tractatus, is that the idea of a limit to thought is self-undermining in the sense that there is no intelligible way in which one can be drawn. Doing so, Wittgenstein is saying here in the Preface, would require having some grasp of what lies beyond such a limit; indeed, the very suggestion of a limit implies that there is something which is being excluded, which lies outside of the range of thought and so cannot be reached.
