 Gradually, these alternatives in reading Philosophical Investigations came to form two schools of interpretation that are broadly parallel to the ones we encounter regarding Wittgenstein’s Tractatus. As noted above (in section 2.4), there is, first, the question of the continuity between Wittgenstein’s earlier and later writings. When emphasis is given – as in the orthodox reading – to Wittgenstein’s switch from logic to grammar, the break between the philosophical stages is easily marked. When, on the contrary, it is the resistance to generalization (of any kind) that is emphasized, then the similarity in Wittgenstein’s therapeutic motivation throughout his life is much more clearly seen.
