Logic is concerned with ordinary sentences, and these sentences are a natural phenomenon in space and time, as the early sections indicated. There are different ways of talking about words, in terms of meaning and in terms of use, just as we can talk about a chess-piece in terms of the rules of chess and its physical properties. Both must be included. Wittgenstein now states that the only activity of his investigation is description , and explanation is given up. We are mistaken in seeking for philosophical explanations.
Philosophy is a battle against the bewitchment of our intelligence by means of language.
Philosophy attempts to take us beyond the limits of language, and in so doing it bumps itself. The right response is to uncover the nonesense which results. These bumps make us see the value of the discovery.
