"Growthmania is the fatal disease of civilisation - it must be replaced by campaigns that make equity and well-being society’s goals - not consuming more junk."
"Too many rich people in the world is a major threat to the human future, and cultural and genetic diversity are great human resources."
"The evidence we have is that toxics reduce the intelligence of children, and members of the first heavily influenced generation are now adults. The first empirical evidence we are dumbing down Homo sapiens were the – and the resultant . On the other hand, toxification may solve the population problem, since sperm counts are plunging."
"To start, make modern contraception and back-up abortion available to all and give women full equal rights, pay and opportunities with men. I hope that would lead to a low enough total fertility rate that the needed shrinkage of population would follow. [But] it will take a very long time to humanely reduce total population to a size that is sustainable."
"As I’ve said many times, ‘perpetual growth is the creed of the cancer cell’."
"If everyone consumed resources at the US level – which is what the world aspires to – you will need another four or five Earths."
"The debate regarding which individual factor, among the three key factors producing the environmental crisis, causes more damage - the size of the human population on the planet, excessive consumption of resources or unequal/ unjust distribution of resources among countries [the wealthier countries consume much more resources than poorer countries] - is like a debate about which contributes more to a triangle, the base or the ribs of the triangle. You can not separate the three factors. If we analyze the numbers over a relatively longer time interval, we will conclude that the size of the population has a bigger impact than consumption. On the other hand, consumption and unequal distribution are also important aspects. If we do not change these three factors all at the same time, the quality of our life will change dramatically. Today humanity is delivering a serious blow to nature, but it is clear that nature will deliver the final blow."
"A series of things have come up since then that have made the problem incredibly grimmer…. The ozone hole… acid rain…. Three hundred million people have starved to death since THE POPULATION BOMB was written. The famines weren’t as large as agriculturists thought they would be… due to the spread of… Green Revolution technology into the poor countries…. What makes us nervous right now is that we’re faced with again having to do something desperate to increase our food production greatly.... In 1965 we knew exactly how to do it, the question was could we deploy it fast enough—Today we have nothing left to deploy—that’s very scary.... As a species we’re not able to live on our income; we’re living on our capital, our deep rich agricultural soils are being destroyed, water is being overpumped, and our biodiversity, our life support system—we’re already far beyond what we can support."
"Actually, the problem in the world is that there are too many rich people."
"In fact, giving society cheap, abundant energy at this point would be the moral equivalent of giving an idiot child a machine gun. With cheap, abundant energy, the attempt clearly would be made to pave, develop, industrialize, and exploit every last bit of the planet—a trend that would inevitably lead to a collapse of the life-support systems upon which civilization depends."
"If I were a gambler, I would take even money that England will not exist in the year 2000"
"Males do not represent two discrete populations, heterosexual and homosexual. The world is not to be divided into sheep and goats. Not all things are black nor all things white. It is a fundamental of taxonomy that nature rarely deals with discrete categories. Only the human mind invents categories and tries to force facts into separated pigeon-holes. The living world is a continuum in each and every one of its aspects. The sooner we learn this concerning human sexual behavior, the sooner we shall reach a sound understanding of the realities of sex."
"At the risk of being repetitious, I would remind the group that we have found the highest frequency of induced abortion in the group which, in general, most frequently uses contraceptives."
"The history of medicine proves that in so far as man seeks to know himself and face his whole nature, he has become free from bewildered fear, despondent shame, or arrant hypocrisy. As long as sex is dealt with in the current confusion of ignorance and sophistication, denial and indulgence, suppression and stimulation, punishment and exploitation, secrecy and display, it will be associated with a duplicity and indecency that lead neither to intellectual honesty nor human dignity."
"The mammalian record thus confirms our statement that any animal which is not too strongly conditioned by some special sort of experience is capable of responding to any adequate stimulus. This is what we find in the more uninhibited segments of our human species, and this is what we find among young children who are not too rigorously restrained in their early sex play. Exclusive preferences and patterns of behavior, heterosexual or homosexual, come only with experience, or as a result of social pressures which tend to force an individual into an exclusive pattern of one or the other sort. Psychologists and psychiatrists, reflecting the mores of the culture in which they have been raised, have spent a good deal of time trying explain the origins of homosexual activity; but considering the physiology of sexual response and the mammalian backgrounds of human behavior, it is not so difficult to explain why a human animal does a particular thing sexually. It is more difficult to explain why each and every individual is not involved in every type of sexual activity."
"The impression that infra-human mammals more or less confine themselves to heterosexual activities is a distortion of the fact which appears to have originated in a man-made philosophy, rather than in specific observations of mammalian behavior. Biologists and psychologists who have accepted the doctrine that the only natural function of sex is reproduction, have simply ignored the existence of sexual activity which is not reproductive. They have assumed that heterosexual responses are a part of an animal's innate, "instinctive" equipment, and that all other types of sexual activity represent "perversions" of the "normal instincts". Such interpretations are, however, mystical. They do not originate in our knowledge of the physiology of sexual response (Chapter 15), and can be maintained only if one assumes that sexual function is in some fashion divorced from the physiologic processes which control other functions of the animal body."
"The inherent physiologic capacity of an animal to respond to any sufficient stimulus seems, then, the basic explanation of the fact that some individuals respond to stimuli originating in other individuals of their own sex-and it appears to indicate that every individual could so respond if the opportunity offered and one were not conditioned against making such responses. There is no need of hypothesizing peculiar hormonal factors that make certain individuals especially liable to engage in homosexual activity, and we know of no data which prove the existence of hormonal factors (p. 758). There are no sufficient data to show that specific hereditary factors are involved. Theories of childhood attachments to one or the other parent, theories of fixation at some infantile level of sexual development, interpretations of homosexuality as neurotic or psychopathic behavior or moral degeneracy, and other philosophic interpretations are not supported by scientific research, and are contrary to the specific data on our series of female and male histories."
"It cannot be too frequently emphasized that the behavior of any animal must depend upon on the nature of the stimulus which it meets, its anatomic and physiologic capacities, and its background of previous experience. Unless it has been conditioned by previous experience, an animal should respond identically to identical stimuli, whether they emanate from some part of its own body, from another individual of the same sex, or from an individual of the opposite sex."
"There is an honesty in science which leads to a certain acceptance of reality. There are some who, finding the ocean an impediment to the pursuit of their designs, try to ignore its existence. If they are unable to ignore it because of its size, they try to legislate it out of existence, or try to dry it up with a sponge. They insist that the latter operation would be possible if enough sponges were available, and if enough persons would wield them. There is no ocean of greater magnitude than the sexual function, and there are those who believe that we would do better if we ignored its existence, that we should not try to understand its material origins, and that if we sufficiently ignore it and mop at the flood of sexual activity with new laws, heavier penalties, more pronouncements, and greater intolerances, we may ultimately eliminate the reality. (page 10)."
"There is an honesty in science which demands that the best means be used for the determination of truth. Certainly there are many sorts of truth in the universe, and many aspects of truth must be taken into account if man is to live most effectively in the social organization to which he belongs. But in regard to matter---the stuff of which both non-living materials and living organisms are made---scientists believe that there is no better way of obtaining information than that provided by human sense organs. No theory, no philosophy, no body of theology, no political expediency, no wishful thinking, can provide a satisfactory substitute for the observation of material objects and of the way in which they behave. (page 9)."
"With the right of the scientist to investigate most aspects of the material universe, most persons will agree; but there are some who have questioned the applicability of scientific methods to an investigation of human sexual behavior....It is as though the dietician and biochemist were denied the right to analyze foods and the processes of nutrition, because the cooking and proper serving of food may be rated a fine art, and because the eating of certain foods has been considered a matter for religious regulation. (page 8)."
"Some scientists hesitate to continue in a given field of research as soon as its application becomes apparent. This refusal to apply knowledge when it exists seems to us, however, to be as unrealistic as the attempt to apply knowledge before it exists. (page 8)"
"The very general occurrence of the homosexual in ancient Greece, and its wide occurrence today in some cultures in which such activity is not taboo suggests that the capacity of an individual to respond erotically to any sort of stimulus, whether it is provided by another person of the same or opposite sex, is basic in the species."
