“[A dark side] is all a shadow is—and though you might be prejudiced against the dark, you ought to remember that that’s where stars live, and the moon and raccoons and owls and fireflies and mushrooms and cats and enchantments and a rather lot of good, necessary things. Thieving, too, and conspiracies, sneaking, secrets, and desire so strong you might faint dead away with the punch of it. But your light side isn’t a perfectly pretty picture, either, I promise you. You couldn’t dream without the dark. You couldn’t rest. You couldn’t even meet a lover on the balcony by moonlight. And what would the world be without that? You need your dark side, because without it, you’re half gone.”
