There is no happiness without knowledge. But knowledge of happiness is unhappy; for knowing ourselves happy is knowing ourselves passing through happiness, and having to, immediatly at once, leave it behind. To know is to kill, in happiness as in everything. Not to know, though, is not to exist.
Fernando PessoaOne or another man, liberated or cursed, suddenly sees-but even this man sees rarely-that all we are is what we aren't, that we fool ourselves about what's true and are wrong about what we conclude is right. And this man, who in a flash sees the universe naked, creates a philosophy or dreams up a religion; and the philosophy spreads and the religion propagates, and those who believe in the philosophy begin to wear it as a suit they don't see, and those who believe in the religion put it on as a mask they soon forget.
