What Copernicus really achieved was not the discovery of a true theory but of a fertile new point of view.

The sole remaining task for philosophy is the analysis of language.

The fact that we can describe the motions of the world using Newtonian mechanics tell us nothing about the world. The fact that we do, does tell us something about the world.

If we were to imagine an orange on the blue side or green on the red side or violet on the yellow side, it would give us the same impression as a north wind coming from the southwest.

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.

For life in the present there is no death. Death is not an event in life. It is not a fact in the world.

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