Philosophy, as we use the word, is a fight against the fascination which forms of expression exert upon us.

Elementary propositions consist of names.

A picture whose pictorial form is logical form is called a logical picture.

An inner process stands in need of outward criteria.

We learn by rearranging what we know.

In order to be able to set a limit to thought, we should have to find both sides of the limit thinkable (i.e. we should have to be able to think what cannot be thought).

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.
