If anyone is unwilling to descend into himself, because this is too painful, he will remain superficial in his writing. . . If I perform to myself, then it’s this that the style expresses.

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.

Nothing is more important for teaching us to understand the concepts we have than to construct fictitious ones.
