Only when one thinks even much more madly than the philosophers can one solve their problems.

If you and I are to live religious lives, it mustn't be that we talk a lot about religion, but that our manner of life is different. It is my belief that only if you try to be helpful to other people will you in the end find your way to God.

If we spoke a different language, we would perceive a somewhat different world.

Language disguises thought.

Propositions show what they say: tautologies and contradictions show that they say nothing.

The sense of the world must lie outside the world... What we cannot speak about we must remain silent about... What can be described can happen too, and what is excluded by the laws of causality cannot be described.

For remember that in general we don't use language according to strict rules-- it hasn't been taught to us by means of strict rules, either. We, in our discussions on the other hand, constantly compare language with a calculus preceding to exact rules.
