A philosopher always finds more grass to feed upon in the valleys of stupidity than on the arid heights of intelligence.

For an answer which cannot be expressed the question too cannot be expressed. The riddle does not exist. If a question can be put at all, then it can also be answered.

Philosophy limits the thinkable and therefore the unthinkable.

The real discovery is the one which enables me to stop doing philosophy when I want to. The one that gives philosophy peace, so that it is no longer tormented by questions which bring itself into question.

Philosophy is like trying to open a safe with a combination lock: each little adjustment of the dials seems to achieve nothing, only when everything is in place does the door open.

The world is everything that is the case.

What is left over if I subtract the fact that my arms goes up from the fact that I raise my arm?
