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.

Think of words as instruments characterized by their use, and then think of the use of a hammer, the use of a chisel, the use of a square, of a glue pot, and of the glue.

A French politician once wrote that it was a peculiarity of the French language that in it words occur in the order in which one thinks them.

Philosophy is not a theory but an activity.

To understand a sentence means to understand a language. To understand a language means to be master of a technique.

Don't ask what it means, but rather how it is used.

The object of philosophy is the logical clarification of thought.
