PREFACE TO THE SECOND EDITION
The text of this volume has been completely revised for this edition, and a number of misreadings have been corrected. These were mostly very small. The most serious one that I have found was the reading of "u.u." ("und umgekehrt) as "u.U" ("unter Umständen"). The diagram on p. 126 has been corrected in accordance with the MS.
The second appendix, Nofes on 'Logic 1913, appears here in a different arrangement from that of the first edition. That edition used the text published in the Journal of Philosophy (Vol. LIV (1957), p. 484) by J. J. Costelloe: he reported having got it from Bertrand Russell in 1914. There was a diflFerent text which the editors had, and which they had also got from Russell. It was clear that the Costelloe version was â slightly corrected total rearrangement of that text under headings, and we assumed that it had been made by Wittgenstein himself.
A debt of gratitude is owing to Brian McGuinness, not only for having pointed out some errors of transcription in the first edition, but also for having proved that the Costelloe version was constructed by Russell. The other one is therefore closer to Wittgenstein, the first part of it being his own dictation in English and the rest a translation by Russell of material dictated by Wittgenstein in German. Mr. McGuinness' article giving the evidence for this can be found in the Revue Internationale de Philosophie, no. 102 (1972).
In the first edition a number of passages of symbolism, in one case with accompanying text, were omitted because nothing could be made of them: they were presumably experimental, but it seemed impossible to interpret them. Nor would it always have been clear what was an exact transcription of them. Photographs of them are printed here as a fourth appendix.
At the 20th of December 1914 there was a rough line of adjacent crayonned patches, using 7 colours. This was treated as a mere doodle in the first edition, and so it may be. But, having regard to the subject matter of meaning and negation, which is the topic of the surrounding text, it is possible that there is here an anticipation of Philosophical Investigations § 48. A representation of it is printed on the dust cover of this edition.
