ABSTRACT
A.Wittgenstein offers us, in the Preface, this summary of the whole sense of the book: “What can be said at all can be said clearly, and about what cannot be spoken of one must be silent.”
He goes on immediately:
Thus the aim of the book is to draw a limit to thought, or rather-not to thought, but to the expression of thoughts: for in order to draw a limit to thought, we should have to be able to think both sides of this limit (we should therefore have to be able to think what cannot be thought).
