The object of philosophy is the logical clarification of thought.

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

Never stay up on the barren heights of cleverness, but come down into the green valleys of silliness.

Man feels the urge to run up against the limits of language. Think for example of the astonishment that anything at all exists. This astonishment cannot be expressed in the form of a question, and there is also no answer whatsoever. Anything we might say is a priori bound to be nonsense. Nevertheless we do run up against the limits of language. Kierkegaard too saw that there is this running up against something, and he referred to it in a fairly similar way (as running up against paradox). This running up against the limits of language is ethics.

In the world everything is as it is and happens as it does happen. In it, there is no value, - and if there were, it would be of no value.

Philosophers are often like little children, who first scribble random lines on a piece of paper with their pencils, and now ask an adult 'What is that?

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.
