Trees, Levels and Ladders

Abstract

The final, unpublished section of Wittgenstein’s so-called "Prototractatus" manuscript allows us to rebuild the gradual course he took to arrive at the definitive structure of the Tractatus. So that it’s now possible to solve the remaining enigmas of the "Korrektur" cited by the author himself in the final pages of the Notebook. The text’s continuity with the preceding parts confirms the top-down technique coherently followed by Wittgenstein in developing the logical tree of his composition.
