In rendering Mr Wittgenstein's Tractatus Logico-Philosophicus available for English readers, the somewhat unusual course has been adopted of printing the original side by side with the translation. Such a method of presentation seemed desirable both on account of the obvious difficulties raised by the vocabulary and in view of the peculiar literary character of the whole. As a result, a certain latitude has been possible in passages to which objection might otherwise be taken as over-literal.
The proofs of the translation and the version of the original which appeared in the final number of Ostwald's Annalen der Naturphilosophie (1921) have been very carefully revised by the author himself; and the Editor further desires to express his indebtedness to Mr F. P. Ramsey, of Trinity College, Cambridge, for assistance both with the translation and in the preparation of the book for the press.
