Logic takes care of itself; all we have to do is to look and see how it does it.

I'm doing philosophy like an old woman, first I'm looking for my pencil, then I'm looking for my glasses, then I'm looking for my pencil again.

The object of philosophy is the logical clarification of thought.

The world is made up of facts, not things.

My propositions serve as elucidations in the following way: anyone who understands me eventually recognizes them as nonsensical, when he has used them--as steps--to climb up beyond them. (He must, so to speak, throw away the ladder after he has climbed up it.) He must transcend these propositions, and then he will see the whole world aright.

Language disguises thought.

In philosophy it is always good to put a question instead of an answer to a question. For an answer to the philosophical question may easily be unfair; disposing of it by means of another question is not.
