“There are periods of history when the visions of madmen and dope fiends are a better guide to reality than the common-sense interpretation of data available to the so-called normal mind. This is one such period, if you haven't noticed already.”

“All that we "know" is what registers on our brains, so what you perceive (your individual reality-tunnel) is made up of nothing but thoughts—as Sir Humphrey Davy noted when self-experimenting with nitrous oxide in 1819, and as Buddha noticed by sitting alone until all his social imprints atrophied and dropped away.”

“Belief in the traditional sense, or certitude, or dogma, amounts to the grandiose delusion, "My current model" -- or grid, or map, or reality-tunnel -- "contains the whole universe and will never need to be revised." In terms of the history of science and knowledge in general, this appears absurd and arrogant to me, and I am perpetually astonished that so many people still manage to live with such a medieval attitude.”

“When we meet somebody whose separate tunnel-reality is obviously far different from ours, we are a bit frightened and always disoriented. We tend to think they are mad, or that they are crooks trying to con us in some way, or that they are hoaxers playing a joke. Yet it is neurologically obvious that no two brains have the same genetically-programmed hard wiring, the same imprints, the same conditioning, the same learning experiences. We are all living in separate realities. That is why communication fails so often, and misunderstandings and resentments are so common. I say "meow" and you say "Bow-wow," and each of us is convinced the other is a bit dumb.”

“It isn't only political power that grows out of the barrel of a gun. So does a whole definition of reality. A set. And the action that has to happen on that particular set and on none other.""Don't be so bloody patronizing," I objected.... "That's just Marx: the ideology of the ruling class becomes the ideology of the whole society.""Not the ideology. The Reality." He lowered his handkerchief. "This was a public park until they changed the definition. Now, the guns have changed the Reality. It isn't a public park. There's more than one kind of magic.""Just like the Enclosure Acts," I said hollowly. "One day the land belonged to the people. The next day it belonged to the landlords.""And like the Narcotics Acts," he added. "A hundred thousand harmless junkies became criminals overnight, by Act of Congress, in nineteen twenty-seven. Ten years later, in thirty-seven, all the pot-heads in the country became criminals overnight, by Act of Congress. And they really were criminals, when the papers were signed. The guns prove it. Walk away from those guns, waving a joint, and refuse to halt when they tell you. Their Imagination will become your Reality in a second.”

“Privilege implies exclusion from privilege, just as advantage implies disadvantage," Celine went on. "In the same mathematically reciprocal way, profit implies loss. If you and I exchange equal goods, that is trade: neither of us profits and neither of us loses. But if we exchange unequal goods, one of us profits and the other loses. Mathematically. Certainly. Now, such mathematically unequal exchanges will always occur because some traders will be shrewder than others. But in total freedom—in anarchy—such unequal exchanges will be sporadic and irregular. A phenomenon of unpredictable periodicity, mathematically speaking. Now look about you, professor—raise your nose from your great books and survey the actual world as it is—and you will not observe such unpredictable functions. You will observe, instead, a mathematically smooth function, a steady profit accruing to one group and an equally steady loss accumulating for all others. Why is this, professor? Because the system is not free or random, any mathematician would tell you a priori. Well, then, where is the determining function, the factor that controls the other variables? You have named it yourself, or Mr. Adler has: the Great Tradition. Privilege, I prefer to call it. When A meets B in the marketplace, they do not bargain as equals. A bargains from a position of privilege; hence, he always profits and B always loses. There is no more Free Market here than there is on the other side of the Iron Curtain. The privileges, or Private Laws—the rules of the game, as promulgated by the Politburo and the General Congress of the Communist Party on that side and by the U.S. government and the Federal Reserve Board on this side—are slightly different; that's all. And it is this that is threatened by anarchists, and by the repressed anarchist in each of us," he concluded, strongly emphasizing the last clause, staring at Drake, not at the professor.”

“Reality is what you can get away with.”
