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.”
