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

Everything that can be thought at all can be thought clearly. Everything that can be said can be said clearly. Ludwig Wittgenstein

It would strike me as ridiculous to want to doubt the existence of Napoleon; but if someone doubted the existence of the earth 150years ago, perhaps I should be more willing to listen, for now he is doubting our whole system of evidence.

In philosophy it is always good to put a question instead of an answer to a question. For an answer to the philosophical question may easily be unfair; disposing of it by means of another question is not.

In order to be able to set a limit to thought, we should have to find both sides of the limit thinkable (i.e. we should have to be able to think what cannot be thought).

In the world everything is as it is and happens as it does happen. In it, there is no value, - and if there were, it would be of no value.

That the world is, is the mystical.
