Why do you write books? ● It seems naive or provocative a question.But the Tractatus Logico-Philosophicus invites us to ask these questions.The first question asked by the same author if the book-any book - consists of two parts. A written and an unwritten part. Wittgenstein was a very bad publicity for himself. In fact he said to von Ficker that he should publish the book that the second part was more important.
The Tractatus is a very strange book ● To get an idea, please read my book, page by page 7, 14.But perhaps you might have after reading a beautiful image of the book and its author. ● Es ist also kein Lehrbuch It is therefore not a text book. ● Das Buch behandelt die Philosophischen Probleme und zeigt dass die Fragestellung dieser Probleme auf dem Missverstandnis der Logik unserer Sprache beruht. ● The book addresses the philosophical problems and shows that the issue of these problems is based on misunderstanding of the logic of our language. ● Das Buch will also dem Denken eine Grenze ziehen. Vielmehr: dem Ausdruck den Gedanken:in der Sprache ● The book will, therefore, draw a limit to thinking. Rather, the expression of the thought : in the language.
Silence ≠ Nonsense ● So the book deals with the meaning and meaninglessness. The nonsense is for example: Socrates abracadabra. The meaning is: The table is brown. Anything that can be said can be said clearly and what you can not speak one must be silent. ● But silence is not the same nonsense. Silence is the second part of the book, more important than the first. Silence is the life,etics.
The values of the Tractatus ● The Tractatus owes his fortune to the fact that, paradoxically, a book was almost incomprehensible. But there was no sense: you could tell he was very sensible. The authors of the circle of Wienna Sclick, Waismmann, Carnap, Popper, but also the author of the Tractatus have always placed a high value.But often for reasons that were not those of Wittgenstein. So what is the value of the Tractatus? Wittgenstein has invented the truth tables. Simplified logic in the future allowing the computer application.He has solved some very famous and important logical paradoxes. He clarified a lot of logical notation. He set up correctly the relationship between idealism and realism(Cap.7-8). It has allowed us to think that problems often are not problems. Namely that language problems are easily surmountable. And in today's life problems are often of language, that of communication.
Misconceptions ● The "disciples" of the Vienna Circle believed for example that Wittgenstein was, like them, a scientist. That the Tractatus was a powerful weapon to eliminate the metaphysical, that is, philosophy. ● Popper thinks the same, but does not prove, that in the Tractatus there is a principle of verification.That is the obvious principle that a proposition is meaningful only if it is verified by the facts.
Popper/ Wittgenstein ● The reading of section 5-6, describes the sharp contrast between Popper and Wittgenstein. Although Popper does not accept the scientism of the circle of Wienna but he thinks that Wittgenstein is being recognized master in charge of the first principle of verification. But in reality Popper attributes to Wittgenstein which is its intention. Popper wants to establish a criterion to distinguish between scientific theories and scientific theories. Even this move is a move scientistic. Only shows to believe that philosophy still has much value.
The principle of verification ● In Wittgenstein there is no principle of verification. Her belief that language and well- formed, that is the logic, is a picture of reality. But this belief becomes for the circles of Vienna a way to abolish philosophy. For Popper, a method for judging scientific theories.Will see that Wittgenstein has no intentions of these also because the so-called principle of verification intended as a method for judging a scientific theory fails.
Scientific theories ● Theory= p; experiment =q.The theory implies an experiment. The experiment succeeds and verified the theory.
Popper: the criterion of falsifiability ● As you can see there is an error. There is an F that is a red falso.Il so-called principle of verification is not a logical law, it is not a tautology. Popper proposed a criterion instead of falsificabilità.Se the experiment fails to say that the theory has been falsified.
