I hope it helps,
(The only point which seems like weird to me, is when you write "I will review" in future, but I have ignored it since it is completely possible for you to plan to review it after your description above)
Today I will review "Wittgenstein A Guide" by Luigi Pernisotto, professor of Linguistics at the University of Venice. In this book, he wants to give an introduction to the tought of Wittgenstein and his contribution to the philosophy of mathematics and linguistics.
The author wants to give his personal point of view at the beginning of the book. According to Pernisotto, it is incorrect to assert that in the Tractatus, his second and most famous book, Wittgenstein radically changes his views on metaphysics. In fact, the author wants to underline how the views of the austrian philosopher, mainly on the impossibility for natural language to fully describe nature opposed to the integrity of the mathematical signs, are coherent and consistent in all of his production.
The author's revolutionary argument is that critics and philosophers had misunderstood the meaning of some of his lectures at Cambridge University, that may appear in contrast with the introduction of the Tractatus. He also wants to allude to firstly how the two italian editions of the Tractatus have not been properly translated, while on the other hand, how the meaning of most quotes of his are different between the original German and some translations in English and French.
In the second part of the book, it becomes clearer how Wittgenstein changed the view on the philosophy of science and language. According to Pernisotto, without the Tractatus, Popper would never stated the criteria of fallibility, a critic of empiricism that draws an evident border between science and pseudo-science besides being fundamental in the understanding of modern physics.
