Wittgenstein wrote the Philosophical Grammar during the years 1931 to 1934 - the period just before he began to dictate the Blue Book. Although it is close to the Investigations in some points, and to the Phiosophische Bemerkungen at others, the Philosophical Grammar is an independent work which covers new ground. It is Wittgenstein's fullest treatment of logic and mathematics in their connection with his later understanding of 'proposition', 'sign', and 'system'. He also discusses inference and generality - critisizing views (...) of Frege and Russell as well as earlier views of his own - and the treatment of mathematical proof in this book, especially of inductive or recursive proofs, is deeper and more extensive than previously.

The so-called "Big Typescript" is Wittgenstein's first attempt to publish in a book his collected thoughts since his return to Cambridge and to philosophical writing, thus correcting the "serious errors" (Wittgenstein) of his early work. Among the texts in Wittgenstein's estate, the "Big Typescript" is the one that, next to the "Logisch-Philosophische Abhandlung" (the "Tractatus") of 1918, appears to be the most "finished", with a table of contents structured in chapters and sections. It is, however, a fragment, without either title, (...) motto or conclusion. To Wittgenstein, it was important "that the thoughts in [the book] should progress from one subject to another in well-ordered consecutiveness." It is precisely this structure of the "Big Typescript", though ultimately rejected by Wittgenstein, which constitutes the immeasurable value of the text for the study of and as an introduction to Wittgenstein's thinking.

Parti INTRODUCTION Wittgenstein sometimes suggested looking on words as instruments, for example in the following passages from ...

While metaphysics is traditionally seen as dealing with the essence of things, for Wittgenstein it is grammar. But what does he mean by "grammar"? And does he mean the same thing by this word throughout his philosophical career? In this investigation, I strive to contribute to answering to these questions. I argue that Wittgenstein's notion of grammar has evolved and changed over the years of his philosophising.

The volume uncovers the most pragmatic and pragmatist aspects of Ludwig Wittgenstein’s philosophy, particularly of On Certainty, through a comparison with the pragmatist tradition as expressed by Charles S. Peirce and William James. On Certainty is often described as 'pragmatic' in literature and this pragmatic aspect is said to characterize a new turn in its author’s thought. Yet, what is still missing is a study of what specifically are the features which make these writings 'sound like pragmatism', as Wittgenstein himself (...) put it (OC 422). The book therefore aims to verify if and to what extent it is possible to sustain that there is an objective convergence between his thought and pragmatism. In doing so, the volume also proposes a clarification of the main differences between Peirce’s and James’ vision of some key ideas of classical pragmatism like doubt and certainty, common sense, the pragmatic maxim, action. Among the achievements of the work are: an analysis of Wittgenstein’s first mention of pragmatism; some pieces of evidence in favour of the hypothesis that Wittgenstein did read some works by Peirce; a documented investigation on the relevance of Frank Ramsey for the development of Wittgenstein’s idea of pragmatism. The volume does not sustain the thesis that Wittgenstein was a pragmatist (nor the opposing thesis that he was not), but highlights the objective convergences and the divergences between his perspective and pragmatism through a balanced analysis running both on an exegetical and on a theoretical level.
