Publisher's Synopsis
The writings preserved in Wittgenstein's manuscripts from 1945 to 1949, after he had completed the first part of "Philosophical Investigations", chiefly concern the nature of certain psychological concepts. In this book the author uses these manuscripts as a basis for reconstructing the central arguments and conceptual elucidations developed by Wittgenstein during that period.;One of the principal subjects is the connection between instinctive reactions, linguistic and non-linguistic context, and mastery of a technique. This connection is explored through clarification of the concepts "experience", "sensation" and "understanding" - a clarification which contributes to the philosophy of psychology, aesthetics and the theory of meaning.;Wittgenstein's thoughts on the logic of language and his reflections on psychological concepts are closely knit. This is shown by his discussion of Moor's paradox, which sheds light both on the limits of logical analysis and on certain curious features of the concepts "believe", "assume" and "assert".;This translation into English with its various amendments and additions aims to bring the work to a wider audience. It should be of use to philosophers with an interest in the mind, cognitive psychologists, anyone interested in Wittgenstein and philosophers of language.
