Philosophy hasn't made any progress? - If somebody scratches the spot where he has an itch, do we have to see some progress? Isn't genuine scratching otherwise, or genuine itching itching? And can't this reaction to an irritation continue in the same way for a long time before a cure for the itching is discovered?

A logical picture of facts is a thought.

This procedure [selecting the simplest law], however, has no logical justification but only a psychological one.

The world is made up of facts, not things.

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.

The logic of the world is prior to all truth and falsehood.

People often say that aesthetics is a branch of psychology. The idea is that once we are more advanced-all the mysteries of art-will be understood by psychological experiments. Exceedingly stupid at this idea is, this is roughly it.
