"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 Si… - Robert Anton Wilson

You need the "is of identity" to describe conspiracy theories. Korzybski would say that proves that illusions, delusions, and "mental" illnesses require the "is" to perpetuate them. (He often said, "Isness is an illness.") Korzybski also popularized the idea that most sentences, especially the sentences that people quarrel over or even go to war over, do not rank as propositions in the logical sense, but belong to the category that Bertrand Russell called propositional functions. They do not have one meaning, as a proposition in logic should have; they have several meanings, like an algebraic function.

The Western World has been brainwashed by Aristotle for the last 2,500 years. The unconscious, not quite articulate, belief of most Occidentals is that there is one map which adequately represents reality. By sheer good luck, every Occidental thinks he or she has the map that fits. Guerrilla ontology, to me, involves shaking up that certainty. I use what in modern physics is called the "multi-model" approach, which is the idea that there is more than one model to cover a given set of facts. As I've said, novel writing involves learning to think like other people. My novels are written so as to force the reader to see things through different reality grids rather than through a single grid. It's important to abolish the unconscious dogmatism that makes people think their way of looking at reality is the only sane way of viewing the world. My goal is to try to get people into a state of generalized agnosticism, not agnosticism about God alone, but agnosticism about everything. If one can only see things according to one's own belief system, one is destined to become virtually deaf, dumb, and blind. It's only possible to see people when one is able to see the world as others see it. That's what guerrilla ontology is — breaking down this one-model view and giving people a multi-model perspective.

"Tell me, Harry, what difference would it make if it wasn't real?"

Harry thought a moment, his chinless face sour. "We wouldn't have to do what we think we have to do. But even if we don't have to do what we think we have to do, it won't make any difference if we do it Which means we should just go ahead."

Mavis sighed. "Just go ahead."

"Just go ahead," said Hagbard. "A powerful mantra."

"And if we don't go ahead," said George, "it doesn't matter either. Which means that we just do go ahead."

"Another powerful mantra," said Hagbard. "Just do go ahead."
