“You have all these fragments, like pieces of a puzzle, and you can place them together into large groups, but the groups don't go together no matter how you try, and then suddenly you get one fragment and it fits two different groups and then suddenly the two great groups are one. The relation of the mythos to insanity. That's a key fragment. I doubt whether anyone ever said that before. Insanity is the terra incognita surrounding the mythos. And he knew! He knew the Quality he talked about lay outside the mythos.”

As quoted in Asadollah Alam (1991), The Shah and I: The Confidential Diary of Iran's Royal Court, 1968-77, page 552

Context: Religion isn't invented by man. Men are invented by religion. Men invent responses to Quality, and among these responses is an understanding of what they themselves are. You know something and then the Quality stimulus hits and then you try to define the Quality stimulus, but to define it all you've got to work with is what you know. So your definition is made up of what you know. It's an analogue to what you already know. It has to be. It can't be anything else. And the mythos grows this way. By analogies to what is known before. The mythos is a building of analogues upon analogues upon analogues. These fill the collective consciousness of all communicating mankind. Every last bit of it. The Quality is the track that directs the train. What is outside the train, to either side—that is the terra incognita of the insane. He knew that to understand Quality he would have to leave the mythos. That's why he felt that slippage. He knew something was about to happen.

Identifying his "destroyed" personality as "Phædrus"
Context: Now I want to begin to fulfill a certain obligation by stating that there was one person, no longer here, who had something to say, and who said it, but whom no one believed or really understood. Forgotten. For reasons that will become apparent I'd prefer that he remain forgotten, but there's no choice other than to reopen his case.
I don't know his whole story. No one ever will, except Phædrus himself, and he can no longer speak. But from his writings and from what others have said and from fragments of my own recall it should be possible to piece together some kind of approximation of what he was talking about.

Non-Fiction, Letters, to Robert E. Howard
Context: It is the night-black Massachusetts legendry which packs the really macabre 'kick', Here is the material for a really profound study in group neuroticism; for certainly, no one can deny the existence of a profoundly morbid streak in the Puritan imagination.... The very pre-ponderance of passionately pious men in the colony was virtually an assurance of unnatural crime; insomuch as psychology now proves the religious instinct to be a form of transmuted eroticism precisely parallel to the transmutations in other directions which respectively produce such things as sadism, hallucination, melancholia, and other mental morbidities. Bunch together a group of people deliberately chosen for strong religious feelings, and you have a practical guarantee of dark morbidities expressed in crime, perversion, and insanity. This was aggravated, of course, by the Puritan policy of rigorously suppressing all the natural outlets of excuberant feeling--music, laughter, colour, pageantry, and so on. To observe Christmas Day was once a prison offence....
