Wittgenstein's principal works, the Tractatus Logico‐Philosophicus and Philosophical Investigations, are each written in such strikingly unconventional ways that it takes considerable effort to translate them into conventional philosophical writing. The most important aspect of Wittgenstein's style for an understanding of his philosophy is his use of multiple voices, and the way he forces his reader to engage with those voices in order to understand him. This chapter provides an outline of the leading macro‐level answers to the question which of Wittgenstein's (...) writings set out his philosophy, and which set out views he rejected. Wittgenstein's method of composition, revision, and rearrangement, leads from the remarks written down in his wartime notebooks, to a manuscript containing several stages of construction of the Prototractatus, and from there to the polished typescript of the Tractatus. The chapter illustrates how to interpret Wittgenstein's remarks without taking a position on questions about texts and style, voice and authorship. (shrink)
