Abstract

Firstly, I will share with you significant Nachlass discoveries that I have made over the past few years which reconstruct an early version of the Philosophical Investigations. It is the version for which the Wittgenstein scholarly community has been searching as the missing text promised to the Cambridge University Press in 1938 with the projected title Philosophische Bemerkungen, and for which the translation that Rhees and Wittgenstein worked on together was made. It is relevant as it is crucially important for us as we consider Wittgenstein as a philosopher of mathematics and physics because this early version spans the well-known TS 220 which constitutes the first part of the published Philosophical Investigations, Remarks 1-189 and the mathematical section of TS 221, which was later published as the first section of Remarks on the Foundations of Mathematics.
