TWO Volumes, octavo, both published by Basil Blackwell, Oxford:
(1) ‘Preliminary Investigations for The ‘Philosophical Investigations’, generally known as ‘The Blue & Books’, 1964 (third impression)/ 1958, xvi, 185 pages.
(2) ‘Philosophical Investigations’, 1963 (second impression)/ 1958 (second edition)/ 1953, x, 232 & 232e pages. (The text is in both English (on the recto), and German (on the verso), hence the 232 & 232e pagination.)
THE BROWN & BLUE BOOKS: ‘These works were composed by Wittgenstein, viva voce in English, and dictated by him, the first to his class at Cambridge, and the second to two pupils. They have been circulated all over the English-speaking world in typescript and many times copied. They show the germination and growth of the ideas which received the final expression in ‘Philosophical Investigations’, and will at times help readers of that book by being crude and more diffuse than it is.’ (Dust jacket).
VERY SCARCE: Currently, there are NO copies of these early edition for sale in Australia. Copies with dust jackets of this quality are scarce worldwide. There are currently no pairs of these titles on sale worldwide.
