“…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…”

“For most of history, man has had to fight nature to survive; in this century he is beginning to realize that, in order to survive, he must protect it.”

“Fear is unnatural. Lightning and thunder are unnatural. Pain, death, reality, these are all unnatural. We can't bear these things as they are. We know too much. So we resort to repression, compromise and disguise. This is how we survive the universe. This is the natural language of the species.”

“Nature is interested in only two things — to survive and to reproduce one like itself. Anything you superimpose on that, all the cultural input, is responsible for the boredom of man.”

“I believe that man is the product of natural evolution that is born from the conflict of being a prisoner and separated from nature, and from the need to find unity and harmony with it.”

“Unless man have a natural bent in accordance with nature's, he has no chance of understanding nature at all.”

“It is the ones who believe in God, who preach peace and talk of love, who have created the human jungle. Compared to man's jungle, nature's jungle is simple and sensible! In nature animals don't kill their own kind. That is part of the beauty of nature. In this regard man is worse than the other animals. The so-called "civilized" man kills for ideals and beliefs, while the animals kill only for survival.”

“So that while we speak of the fallen man as the natural man, as against the supernatural man, who is a redeemed man in a very real sense we should say that sin is unnatural. With man, who was created into perfect knowledge, and his destiny is hell or salvation. Moreover man was created to exercise dominion and to rule the earth. This is man’s calling and it is basic to man’s nature.”

“In philosophical anthropology, … where the subject is man in his wholeness, the investigator cannot content himself, as in anthropology as an individual science, with considering man as another part of nature and with ignoring the fact that he, the investigator, is himself a man and experiences this humanity in his inner experience in a way that he simply cannot experience any part of nature.”

“Poverty, ignorance, illness and other problems of that kind are not metaphysical emergencies. By the metaphysical nature of man and of existence, man has to maintain his life by his own effort; the values he needs—such as wealth or knowledge—are not given to him automatically, as a gift of nature, but have to be discovered and achieved by his own thinking and work.”
