It's only by thinking even more crazily than philosophers do that you can solve their problems. - Ludwig Wittgenstein

At the foundation of well-founded belief lies belief that is not founded.

In order to avoid these errors, we must employ a symbolism which excludes them, by not applying the same sign in different symbols and by not applying signs in the same way which signify in different ways. A symbolism, that is to say, which obeys the rules of logical grammar — of logical syntax. (The logical symbolism of Frege and Russell is such a language, which, however, does still not exclude all errors.)

The right method of philosophy would be this. To say nothing except what can be said, i.e. the propositions of natural science, i.e. something that has nothing to do with philosophy: and then always, when someone else wished to say something metaphysical, to demonstrate to him that he had given no meaning to certain signs in his propositions. This method would be unsatisfying to the other — he would not have the feeling that we were teaching him philosophy — but it would be the only strictly correct method.
