One of Wittgenstein’s final works, written in Oxford in 1950, the year before he died. The text is notably fragmentary, drawn from ‘loose sheets of foolscap’ left in Wittgenstein’s room in Elizabeth Anscombe’s house in Oxford ‘when he went to Dr. Bevan’s house in Cambridge in February 1951, in the expectation of dying there’ (Editor’s Preface). The fragments respond variously to the use of language about colour, addressing the difficult logic of concepts of colour and the language games in which they are situated.
