A philosopher who is not taking part in discussions is like a boxer who never goes into the ring.

What do I know about God and the purpose of life? I know that this world exists. That I am placed in it like my eye in its visual field. That something about it is problematic, which we call its meaning. This meaning does not lie in it but outside of it. That life is the world. That my will penetrates the world. That my will is good or evil. Therefore that good and evil are somehow connected with the meaning of the world.The meaning of life, i.e. the meaning of the world, we can call God. And connect with this the comparison of God to a father.

The real discovery is the one which enables me to stop doing philosophy when I want to. The one that gives philosophy peace, so that it is no longer tormented by questions which bring itself into question.

The process of induction is the process of assuming the simplest law that can be made to harmonize with our experience.

Propositions show what they say: tautologies and contradictions show that they say nothing.
