We have no need of other worlds. We need mirrors. We don't know what to do with other worlds. A single world, our own, suffices us; but we can't accept it for what it is.

There are no answers, only choices.

Psychoanalysis provides truth in an infantile, that is, a schoolboy fashion: we learn from it, roughly and hurriedly, things that scandalize us and thereby command our attention. It sometimes happens, and such is the case here, that a simplification touching upon the truth, but cheaply, is of no more value than a lie. Once again we are shown the demon and the angel, the beast and the god locked in Manichean embrace, and once again man has been pronounced, by himself, not culpable.

You believe by doubting and you doubt by believing; yet this state too is not the final one.
