The aspects of things that are most important for us are hidden because of their simplicity and familiarity. (One is unable to notice something because it is always before one’s eyes.) The real foundations of his enquiry do not strike a man at all

Philosophy is a battle against the bewitchment of our intelligence by means of language.

When you are philosophizing you have to descend into primeval chaos and feel at home there.

The classifications made by philosophers and psychologists are like trying to classify clouds by their shape.

The truth of the thoughts that are here set forth seems to me unassailable and definitive. I therefore believe myself to have found, on all essential points, the final solution of the problems. And if I am not mistaken in this belief, then the second thing in which the value of this work consists is that it shows how little is achieved when these problems are solved.

What we cannot speak about we must pass over in silence.

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.
