The object of philosophy is the logical clarification of thought.

Philosophy is not a theory but an activity.

A man will be imprisoned in a room with a door that's unlocked and opens inwards; as long as it does not occur to him to pull rather than push it.

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.

When one is frightened of the truth then it is never the whole truth that one has an inkling of.

Death is not an event in life: we do not live to experience death.

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.
