Paul La Farge said this quote

As a Freudian, I'm not supposed to use words like evil; my business is with instinct, memory, and desire. Nevertheless, I've been wondering, lately, whether evil might exist. If it does, I've been thinking, it might be like what Freud called the navel of the dream, the place where all the lines of meaning the analyst has so carefully traced through the patient's life vanish into the unknown. But where the navel of the dream is essentially harmless phenomenon, a point where the dream's meaning is sufficiently understood, and further interpretation would be pointless, evil is a mystery with power. It reaches up into the world and makes everything mysterious.

Clearly, you don't know much about horror, he said. Horror is premised on the experience of what we do not and cannot understand, whereas what you're talking about is mere low-class smut, which every schoolboy has encountered before he's in long pants.

~ Paul La Farge

The American id could not be educated, Spinks thought. It needed horror in order to stay awake and to justify its most pleasureful pursuit, the destruction of helpless people who had never done anything wrong.
