Wittgenstein wrote this book during 1932-1934 - the period just before he began to dictate the Blue Book. In Part I he discusses the notions of "proposition," "sense," "language," "grammar"; what "saying something" is, what distinguishes signs form random marks or noises. Must we start with "primary" signs which need no explanation? In what sense have we a general concept of proposition or of language? The phrases "family of cases" and "family similarities," which the Investigations use, are here; and comparison brings out what is special in the later development. But although it is close to the Investigations at some points, and to the Philosophische Bemerkungen at others, the Philosophical Grammar is an independent work and discusses much that is not in either of them. It is Wittgenstein's fullest treatment of logic and mathematics in their connection with his later understanding of "proposition," "sign," and "system." In Part II he writes on logical inference and generality - criticizing views of Frege and Russell and earlier views of his own, developing his conception of "law of a series" and of "...and so on" - leading to his discussion of mathematics, which fills two fifths of the volume: the ideas of "foundations of mathematics," of cardinal numbers, of mathematical proof, and especially of inductive or recursive proofs (with reference to Skolem), which he treats to a depth and extent beyond anything he said of them elsewhere

Lectures & conversations on aesthetics, psychology, and religious belief by Ludwig Wittgenstein ( Book )
121 editions published between 1966 and 2010 in 6 languages and held by 1,897 WorldCat member libraries worldwide
The first thing to be said about this book is that nothing contained herein was written by Wittgenstein himself. The notes published here are not Wittgenstein's own lecture notes, but notes taken down by students, which he neither saw nor checked. It is even doubtful if he would have approved of their publication, as least in their present form. Since, however, they deal with topics only briefly touched upon in his other published writings, and since for some time they have been circulating privately, it was thought best to publish them in a form approved by their authors

Part III of this volume reproduces most of a MS book written in oxford in the Spring of 1950. I have left out material on "inner-outer", remarks about Shakespeare and some general observations about life; all this both was marked as discontinuous with the text and also will appear elsewhere. Part I was written in Cambridge in March 1951: it is a selection and revision of the earlier material, with few additions. It is not clear whether Part II ante- or post-dates Part III. It was part of what was written on undated loose sheets of foolscap, the rest being devoted to certainty
