“Man wants to see nature and evolution as separate from human activities. There is a natural world, and there is man. But man also belongs to the natural world. If he is a ferocious predator, that too is part of evolution. If cod and haddock and other species cannot survive because man kills them, something more adaptable will take their place. Nature, the ultimate pragmatist, doggedly searches for something that works. But as the cockroach demonstrates, what works best in nature does not always appeal to us.”

“Now observe that in all the propaganda of the ecologists—amidst all their appeals to nature and pleas for “harmony with nature”—there is no discussion of man’s needs and the requirements of his survival. Man is treated as if he were an unnatural phenomenon. Man cannot survive in the kind of state of nature that the ecologists envision—i.e., on the level of sea urchins or polar bears....In order to survive, man has to discover and produce everything he needs, which means that he has to alter his background and adapt it to his needs. Nature has not equipped him for adapting himself to his background in the manner of animals. From the most primitive cultures to the most advanced civilizations, man has had to manufacture things; his well-being depends on his success at production. The lowest human tribe cannot survive without that alleged source of pollution: fire. It is not merely symbolic that fire was the property of the gods which Prometheus brought to man. The ecologists are the new vultures swarming to extinguish that fire.”

“The work of man is done behind the back of the natural world. When nature notices, and can muster the energy, it wipes the slate clean again.”

“We mustn't be afraid of inventing anything...Everething there is in us exists in nature. After all, we're part of nature. If it resembles nature, that's fine. If it doesn't, what of it? When man wanted to invent something as useful as the human foot, he invented the wheel, which he used to transport himself and his burdens. The fact that the wheel doesn't have the slightest resemblance to the human foot is hardly a criticism of it.”

“The world is... the natural setting of, and field for, all my thoughts and all my explicit perceptions. Truth does not inhabit only the inner man, or more accurately, there is no inner man, man is in the world, and only in the world does he know himself. ”

“The natural world is so adaptable...So adaptable you wonder what's natural.”
