The problems are solved, not by giving new information, but by arranging what we have always known.

To think that you are not following a rule is to follow a rule.

Philosophy is a battle against the bewitchment of our intelligence by means of language.

Since social relationships are always ambiguous, since my thought is only a unit, since my thoughts create rifts as much as they unite, since my words establish contacts by being spoken and create isolation by remaining unspoken, since an immense moat separates the subjective certitude that I have for myself from the objective reality that I represent to others, since I never stop finding myself guilty even though I feel I am innocent.

Language is a part of our organism and no less complicated than it.
