Criss-crossing a Philosophical Landscape

The Troubled History of Part II of the Investigations
The typescripts from which both parts of Wittgenstein's Investigations were printed are now lost. Of the TS for Part I there exists a second copy, but not so of the TS for Part II. There is, however, a manuscript in Wittgenstein's hand which contains the whole of the printed Part II - and some additional material. A comparision of this MS with the printed text reveals some interesting discrepancies. They are noted in the paper. Moreover, a detailed comparision is made in a Postscript between the printed Preface of the Investigations and another, obviously earlier, version of it. Both versions are dated "Cambridge, January 1945" - but the printed one was probably not prepared until two years later.
