And how do you know that you're mad? "To begin with," said the Cat, "a dog's not mad. You grant that?" I suppose so, said Alice. "Well then," the Cat went on, "you see a dog growls when it's angry, and wags it's tail when it's pleased. Now I growl when I'm pleased, and wag my tail when I'm angry. Therefore I'm mad.

To feel our character, our personality, and our personal, hard-won history fade from being is to be exposed to whatever lies beneath these comforting, operational conveniences. What remains when the conscious and functioning self has been erased is mankind's fundamental condition – irrational, violent, guilt-wracked, despairing, and mad.

That night I slept badly, thrashing about in my bed, not quite asleep and not quite awake. At times I had the feeling there was someone else in my bedroom who was talking to me, but of course I could not deal with this perception in any realistic way, since I was half-asleep and half-awake, and thus, for all practical purposes, I was out of my mind.

My soul is a black maelstrom, a great madness spinning about a vacuum, the swirling of a vast ocean around a hole in the void, and in the waters, more like whirlwinds than waters, float images of all I ever saw or heard in the world: houses, faces, books, boxes, snatches of music and fragments of voices, all caught up in a sinister, bottomless whirlpool.

¿Quien sabe? Quizas ellos tengan razón. Quizas estamos siendo manejados como locos por nuestros sentimientos. Quizas el amor es una enfermedad y estaríamos mejor sin ella. Pero nosotros elegimos una ruta diferente. Y al final, ese es el punto de escapar de la cura: Somos libres para elegir. Somos incluso libres para elegir algo horrible.

Perhaps love is a minor madness. And as with madness, it's unendurable alone. The one person who can relieve us is of course the sole person we cannot go to: the one we love. So instead we seek out allies, even among strangers and wives, fellow patients who, if they can't touch the edge of our particular sorrow, have felt something that cuts nearly as deep.

(there is) no other means of escaping from one's consciousness than to deny it, to look upon it as an organic disease of the terrestrial intelligence - a disease which we must endeavor to cure by an action which must appear to us an action of violent and willful madness, but which, on the other side of our appearances, is probably an action of health. ("Of Immortality")

If there was one thing I feared as I was growing up . . . No, that's stupid. I feared hundreds of things: the dark, the death of my father, the possibility that I might rejoice the death of my mother, sums involving vernier calipers, groups of schoolboys with nothing much to do, death by drowning. But of all these, I feared the most the possibility that I might go mad too.

Almost every day I can feel myself suffering mainly in the head, I can explain the pain to myself but knowing it comes from an inflammation of my imagination doesn't prevent it being reality itself. What's more I'd be crazy not to go crazy. We don't know what an illness is. On awful hurts we plaster little old words, as if we could think hell with a paper bandage.

When faced with unbridled wildness of reality, dinosaurs fall into fevered delusions of grandeur. In fits of madness, they recreate the world in their own overblown image, bull-dozing the wild and replacing it with a wasteland that reflects their own emptiness. Where there was once the incredibly complex diversity of nature, there is now the dead simplicity of asphalt and concrete.

The origin of illness may be in the past, but the virulent crisis must be dynamically tackled. I believe in attacking the core of the illness, through its present symptoms, quickly, directly. The past is a labyrinth. One does not have to step into it and move step by step through every turn and twist. The past reveals itself instantly, in today’s fever or abscess of the soul.

I wanted to throw off the chains that bound me and give my entire being to someone. I wanted to know what it felt like to love another so much that the whole world came crashing down around me when it ended. I wanted obsession. I wanted madness. I wanted something all-consuming. And now that I realized it, I didn’t think that I would ever be the same again. And that terrified me.

You who understand what a human mind can be, how can you bear it? I don't have the hundredth part of your mind and there are days when I think I'll go mad. I can feel it. Or hear it. It's more like hearing something creeping along the walls, just behind my head, getting closer and closer. A big insect, maybe a scorpion. A dry skittering, that's what madness sounds like to me.

Theo's already on his way. Paul might bee too, but communications have been down so long, I don't know.""Heading out here with a storm like this coming in? That's madness." Dad sighs. "Then again, jumping through dimensions to chase a dead man is madness too. I had long suspected their lunacy but this confirmation is nonetheless disquieting.""See? Everything's going to be fine.

Soon madness has worn you down. It’s easier to do what it says than argue. In this way, it takes over your mind. You no longer know where it ends and you begin. You believe anything it says. You do what it tells you, no matter how extreme or absurd. If it says you’re worthless, you agree. You plead for it to stop. You promise to behave. You are on your knees before it, and it laughs.
