“It was the ghost of rationality itself ... This is the ghost of normal everyday assumptions which declares that the ultimate purpose of life, which is to keep alive, is impossible, but that this is the ultimate purpose of life anyway, so that great minds struggle to cure diseases so that people may live longer, but only madmen ask why. One lives longer in order that he may live longer. There is no other purpose. That is what the ghost says.”

“The law of gravity and gravity itself did not exist before Isaac Newton." ...and what that means is that that law of gravity exists nowhere except in people's heads! It 's a ghost!"Mind has no matter or energy but they can't escape its predominance over everything they do. Logic exists in the mind. numbers exist only in the mind. I don't get upset when scientists say that ghosts exist in the mind. it's that only that gets me. science is only in your mind too, it's just that that doesn't make it bad. or ghosts either."Laws of nature are human inventions, like ghosts. Law of logic, of mathematics are also human inventions, like ghosts."...we see what we see because these ghosts show it to us, ghosts of Moses and Christ and the Buddha, and Plato, and Descartes, and Rousseau and Jefferson and Lincoln, on and on and on. Isaac Newton is a very good ghost. One of the best. Your common sense is nothing more than the voices of thousands and thousands of these ghosts from the past.”

“The cause of our current social crises, he would have said, is a genetic defect within the nature of reason itself. And until this genetic defect is cleared, the crises will continue. Our current modes of rationality are not moving society forward into a better world. They are taking it further and further from that better world. Since the Renaissance these modes have worked. As long as the need for food, clothing and shelter is dominant they will continue to work. But now that for huge masses of people these needs no longer overwhelm everything else, the whole structure of reason, handed down to us from ancient times, is no longer adequate. It begins to be seen for what it really is…emotionally hollow, esthetically meaningless and spiritually empty.”

“Now the stream of our common consciousness seems to be obliterating its own banks, losing its central direction and purpose, flooding the lowlands, disconnecting and isolating the highlands and to no particular purpose other than the wasteful fulfillment of its own internal momentum”

“Your common sense is nothing more than the voices of thousands and thousands of these ghosts from the past.”

“But to tear down a factory or to revolt against a government or to avoid repair of a motorcycle because it is a system is to attack effects rather than causes; and as long as the attack is upon effects only, no change is possible. The true system, the real system, is our present construction of systematic thought itself, rationality itself, and if a factory is torn down but the rationality which produced it is left standing, then that rationality will simply produce another factory. If a revolution destroys a systematic government, but the systematic patterns of thought that produced that government are left intact, then those patterns will repeat themselves in the succeeding government. There’s so much talk about the system. And so little understanding.”

“To live only for some future goal is shallow. It's the sides of the mountain that sustain life, not the top.”
