ABSTRACT
The volume of Wittgenstein’s writings entitled Notebooks 1914-161 contains as Appendix A one version of Wittgenstein’s so-called ‘Notes on Logic’. In the first edition (all printings down to 1979), which will be referred to throughout this paper, this is the version first printed in the Journal of Philosophy, liv, no. 9 (1957), 230-245 with a note by Harry T. Costello explaining that he copied it from a manuscript dated September 1913 brought to Harvard by Russell in the spring of 1914. This ‘manuscript’ and the copy made of it by Costello are at present lost, but two earlier stages of the work still exist in the Bertrand Russell Archive of McMaster University. The second of these is a pair of typescripts, one foliated 1-8 and entitled ‘Summary’, the other foliated 1-25 and containing the following headings: ‘First MS’ on f.1, ‘Second MS’ on f.4, ‘3rd MS’ on f.8, and ‘4th. MS’ on f.17. (Other features of these typescripts will be described later.) These typescripts are evidently those shown by Russell to Mr. D. Shwayder in the early 1950s, at which time copies made from them enjoyed a certain circulation.
