"In particular, while natural selection favors both males and females that leave many offspring, the best strategy for doing so may be different for fathers and mothers. That generates a built-in conflict between the parents, a conclusion that all too many humans don’t need scientists to reveal to them. We make jokes about the battle of the sexes, but the battle is neither a joke nor an aberrant accident of how individual fathers or mothers behave on particular occasions. It is indeed perfectly true that behavior that is in a male’s genetic interests may not necessarily be in the interests of his female co-parent, and vice versa. That cruel fact is one of the fundamental causes of human misery."
"Though seemingly remote from human sexuality, shorebird sexuality is instructive because it illustrates the main message of this book: a species’ sexuality is molded by other aspects of the species’ biology. It’s easier for us to acknowledge this conclusion about shorebirds, to which we don’t apply moral standards, than about ourselves."
"How can we explain simultaneously this general pattern of female parental care and also its numerous exceptions? The answer comes from the realization that genes for behavior, as well as for malaria resistance and teeth, are subject to natural selection."
"Physiologists and molecular biologists regularly fall into the trap of overlooking this distinction, which is fundamental to biology, history, and human behavior. Physiology and molecular biology can do no more than identify proximate mechanisms; only evolutionary biology can provide ultimate causal explanations."
"The infectious diseases that regularly visited crowded Eurasian societies, and to which many Eurasians consequently developed immune or genetic resistance, included all of history's most lethal killers: smallpox, measles, influenza, plague, tuberculosis, typhus, cholera, malaria, and others."
"Compressing 13,000 years of history on all continents into a 400-page book works out to an average of about one page per continent per 150 years, making brevity and simplification inevitable. Yet the compression brings a compensating benefit: long-term comparisons of regions yield insights that cannot be won from short-term studies of single societies."
"Technological advances seem to come disproportionately from a few very rare geniuses, such as Johannes Gutenberg, James Watt, Thomas Edison, and the Wright brothers. They were Europeans, or descendants of European emigrants to America. So were Archimedes and other rare geniuses of ancient times. Could such geniuses have equally well been born in Tasmania or Namibia? Does the history of technology depend on nothing more than accidents of the birthplaces of a few inventors?"
"History, as well as life itself, is complicated; neither life nor history is an enterprise for those who seek simplicity and consistency."
"Just as strawberries are adapted to birds, so acorns are adapted to squirrels, mangos to bats, and some sedges to ants. That fulfills part of our definition of plant domestication, as the genetic modification of an ancestral plant in ways that make it more useful to consumers. But no one would seriously describe this evolutionary process as domestication, because birds and bats and other animal consumers don't fulfill the other part of the definition: they don't consciously grow plants."
"As we shall see in this book's chapters, traditional societies are far more diverse in many of their cultural practices than are modern industrial societies. [...] Yet psychologists base most of their generalizations about human nature on studies of our own narrow and atypical slice of human diversity. [...] That is, as social scientists Joseph Henrich, Steven Heine, and Ara Norenzayan express it, most of our understanding of human psychology is based on subjects who may be described by the acronym WEIRD: from Western, educated, industrialized, rich, and democratic societies. [...] Hence if we wish to generalize about human nature, we need to broaden greatly our study sample from the usual WEIRD subjects [...] to the whole range of traditional societies."
"White blood cells and other cells of ours actively seek out and kill foreign microbes. The specific antibodies that we gradually build up against a particular microbe infecting us make us less likely to get reinfected once we become cured. As we all know from experience, there are some illnesses, such as flu and the common cold, to which our resistance is only temporary; we can eventually contract the illness again. Against other illnesses, though—including measles, mumps, rubella, pertussis, and the now defeated smallpox — our antibodies stimulated by one infection confer lifelong immunity. That's the principle of vaccination: to stimulate our antibody production without our having to go through the actual experience of the disease, by inoculating us with a dead or weakened strain of microbe."
"We have already discovered two species that are very intelligent but technically less advanced than us — the common chimpanzee and pygmy chimpanzee. Has our response been to sit down and try to communicate with them? Of course not. Instead we shoot them, stuff them, dissect them, cut off their hands for trophies, put them on exhibit in cages, inject them with AIDS virus as a medical experiment, and destroy or take over their habitat. That response was predictable, because human explorers who discovered technically less advanced humans also regularly responded by shooting them, decimating their populations with new diseases, and destroying or taking over their habitat. Any advanced extraterrestrials who discovered us would surely treat us in the same way...If there really are any radio civilizations within listening distance of us, then for heaven's sake let's turn off our own transmitters and try to escape detection, or we are doomed."
"The details of which candidate said what during a single televised debate in October 1960 could have given the electoral victory to Nixon instead of to Kennedy, but no details of who said what could have blocked the European conquest of Native Americans."
"Put another way, the chimpanzees' closest relative is not the gorilla but humans."
"Perhaps we could benefit by selectively adopting some of those traditional practices. Some of us already do so, with demonstrated benefits to our health and happiness. In some respects we moderns are misfits; our bodies and our practices now face conditions different from those under which they evolved, and to which they became adapted. But we should also not go to the opposite extreme of romanticizing the past and longing for simpler times. Many traditional practices are ones that we can consider ourselves blessed to have discarded — such as infanticide, abandoning or killing elderly people, facing periodic risk of starvation, being at heightened risk from environmental dangers and infectious diseases, often seeing one’s children die, and living in constant fear of being attacked. Traditional societies may not only suggest to us some better living practices, but may also help us appreciate some advantages of our own society that we take for granted."
"The societies to which most readers of this book belong represent a narrow slice of human cultural diversity. Societies from that slice achieved world dominance not because of a general superiority, but for specific reasons: their technological, political, and military advantages derived from their early origins of agriculture, due in turn to their productive local wild domesticable plant and animal species. Despite those particular advantages, modern industrial societies didn’t also develop superior approaches to raising children, treating the elderly, settling disputes, avoiding non-communicable diseases, and other societal problems. Thousands of traditional societies developed a wide array of different approaches to those problems."
"The central principle of Fritz Bauer's career was that Germans should hold judgement upon themselves. That meant prosecuting ordinary Germans, not just the leaders whom the Allies had prosecuted. [...] The Nazi defendants being prosecuted by Bauer all tended to offer the same set of excuses [...]. Bauer's response, which he formulated again and again at the trials and in public, was as follows. Those Germans whom he was prosecuting were committing crimes against humanity. The laws of the Nazi state were illegitimate. One cannot defend one's actions by saying that one was obeying those laws. There is no law that can justify a crime against humanity. Everybody must have his own sense of right and wrong and must obey it, independently of what a state government says. Anyone who takes part in what Bauer called a murder machine [...] thereby becomes guilty of a crime."
"Guns, Germs, and Steel pushed geography as an academic discipline into the debates of economic historians in much the same way that Graeber intends for anthropology."
"Affirmative action has to be combined with a broader program of social reform that would emphasize social rights: the right to employment, the right to education, the right to good health. Over the years, black leaders have been slow to recognize the need for a very, very progressive agenda. Anytime someone has talked about putting America back to work, blacks should have said yes, but they didn't. They were so preoccupied with affirmative action that they didn't provide the kind of leadership that would help some of the other progressive folks. Only now are black leaders beginning to realize the impact of economic issues."
"Liberals were intimidated by the Reagan administration and did not want to appear naive by talking about programs that called for government support. I just said, 'The hell with that. I'm out there. I'm exposed with this book.'"
"A lot of joblessness in the black community doesn't seem to be reachable through fiscal and monetary policies. People have not been drawn into the labor market even during periods of economic recovery. Our study clearly shows that employers would rather not hire a lot of workers from the inner city. They feel people from the inner city are not job-ready, that the kids have been poorly educated, that they can't read, they can't write, they can't speak."
"Racism should be viewed as an intervening variable. You give me a set of conditions and I can produce racism in any society. You give me a different set of conditions and I can reduce racism. You give me a situation where there are a sufficient number of social resources so people don't have to compete for those resources, and I will show you a society where racism is held in check. If we could create the conditions that make racism difficult, or discourage it, then there would be less stress and less need for affirmative action programs. One of those conditions would be an economic policy that would create tight labor markets over long periods of time. Now does that mean that affirmative action is here only temporarily? I think the ultimate goal should be to remove it."
"The problems we see today are going to be a hell of a lot worse in 10 years if we're not willing to face up to them. These kids are just not going to be absorbed into the economy, so what are they going to be doing? Well, we know. They're going to be making life pretty miserable for a lot of people."
"Organizations need to undergo fundamental changes, both in order to adapt to the new business environment and to become ecologically sustainable."
"Peter Senge (1990), Fritjof Capra (1996), Peter Checkland (1999), and other researchers have transferred systems thinking principles and theories into practice by applying them to real-world organizational-wide issues, thus encouraging the creation and development of learning organizations."
"One of the key insights of the systems approach has been the realization that the network is a pattern that is common to all life. Wherever we see life, we see networks."
"The principle of flexibility... suggests a corresponding strategy of conflict resolution. ...the community will need stability and change, order and freedom, tradition and innovation. ...these unavoidable conflicts are much better resolved by establishing a dynamic balance."
"A diverse community is a resilient community, capable of adapting to changing situations."
"Lack of flexibility manifests itself as stress. ...stress will occur when one or more variables of the system are pushed to their extreme values, which induces increased rigidity throughout the system."
"Partnership—the tendency to associate, establish links, live inside one another, and cooperate—is one of the hallmarks of life."
"Economics emphasizes competition, expansion, and domination; ecology emphasizes cooperation, conservation, and partnership."
"The so-called free market does not provide consumers with proper information, because the social and environmental costs of production are not part of the current economic models. ...an ecological tax reform would be strictly revenue neutral, shifting the tax burden from income taxes to "eco-taxes." …the taxes would be added to existing products, forms of energy, services, and materials, so that prices would better reflect true costs."
"These, then, are some of the basic principles of ecology—interdependence, recycling, partnership, flexibiility, diversity, and, as a consequence of all those, sustainability ...the survival of humanity will depend on our ecological literacy, on our ability to understand these principles of ecology and live accordingly."
"The Buddhist doctrine of impermanence includes the notion that there is no self... It holds that the idea of a separate, individual self is an illusion, just another form of maya, an intellectual concept that has no reality. To cling to this idea of a separate self leads to the same pain and suffering (duhkha) as the adherence to any other fixed category of thought."
"There is no self-awareness in ecosystems, no language, no consciousness, and no culture; and therefore no justice and democracy; but also no greed or dishonesty."
"With the subsequent strong support from cybernetics, the concepts of systems thinking and systems theory became integral parts of the established scientific language, and led to numerous new methodologies and applications - systems engineering, systems analysis, systems dynamics, and so on."
"Tektology was the first attempt in the history of science to arrive at a systematic formulation of the principles of organization operating in living and nonliving systems."
"Before the 1940s the terms "system" and "systems thinking" had been used by several scientists, but it was Bertalanffy's concepts of an open system and a general systems theory that established systems thinking as a major scientific movement"
"In the Germany of the 1920s, the Weimar Republic, both organismic biology and Gestalt psychology were part of a larger intellectual trend that saw itself as a protest movement against the increasing fragmentation and alienation of human nature. The entire Weimar culture was characterized by an antimechanistic outlook, a "hunger for wholeness". Organismic biology, Gestalt psychology, ecology, and, later on, general systems theory all grew out of this holistic zeitgeist."
"Understanding ecological interdependence means understanding relationships. It requires the shifts of perception that are characteristic of systems thinking—from the parts to the whole, from objects to relationships, from contents to patterns. ...Nourishing the community means nourishing those relationships."
"The more we study the major problems of our time, the more we come to realise that they cannot be understood in isolation. They are systemic problems, which means that they are interconnected and interdependent."
"The ideas set forth by organismic biologists during the first half of the twentieth century helped to give birth to a new way of thinking — "systems thinking" — in terms of connectedness, relationships, context. According to the systems view, the essential properties of an organism, or living system, are properties of the whole, which none of the parts have. They arise from the interactions and relationships among the parts. These properties are destroyed when the system is dissected, either physically or theoretically, into isolated elements. Although we can discern individual parts in any system, these parts are not isolated, and the nature of the whole is always different from the mere sum of its parts. The systems view of life is illustrated beautifully and abundantly in the writings of Paul Weiss, who brought systems concepts to the life sciences from his earlier studies of engineering and spent his whole life exploring and advocating a full organismic conception of biology."
"In 1929, Heisenberg spent some time in India as the guest of the celebrated Indian poet Rabindranath Tagore, with whom he had long conversations about science and Indian philosophy. This introduction to Indian thought brought Heisenberg great comfort, he told me. He began to see that the recognition of relativity, interconnectedness, and impermanence as fundamental aspects of physical reality, which had been so difficult for himself and his fellow physicists, was the very basis of the Indian spiritual traditions. “After these conversations with Tagore,” he said, “some of the ideas that had seemed so crazy suddenly made much more sense. That was a great help for me.”"
"The term "paradigm," from the Greek paradeigma ("pattern"), was used by Kuhn to denote a conceptual framework shared by a community of scientists and providing them with model problems and solutions"
"The realization that systems are integrated wholes that cannot be understood by analysis was even more shocking in physics than in biology. Ever since Newton, physicists had believed that all physical phenomena could be reduced to the properties of hard and solid material particles. In the 1920s, however, quantum theory forced them to accept the fact that the solid material objects of classical physics dissolve at the subatomic level into wavelike patterns of probabilities. These patterns, moreover, do not represent probabilities of things, but rather probabilities of interconnections. The subatomic particles have no meaning as isolated entities but can be understood only as interconnections, or correlations, among various processes of observation and measurement. In other words, subatomic particles are not “things” but interconnections among things, and these, in turn, are interconnections among other things, and so on. In quantum theory we never end up with any “things”; we always deal with interconnections."
"[Capra for instance, uses the term "Paradigm" to mean] the totality of thoughts, perceptions, and values that form a particular vision of reality, a vision that is the basis of the way a society organizes itself"
"A major clash between economics and ecology derives from the fact that nature is cyclical, whereas our industrial systems are linear. Our businesses take resources, transform them into products plus waste, and sell the products to consumers, who discard more waste..."
"What we need, then, is a new 'paradigm' – a new vision of reality; a fundamental change in our thoughts, perceptions, and values. The beginnings of this change, of the shift from the mechanistic to the holistic conception of reality, are already visible in all fields and are likely to dominate the present decade. The various manifestations and implications of this 'paradigm shift' are the subject of this book. The sixties and seventies have generated a whole series of social movements that all seem to go in the same direction, emphasizing different aspects of the new vision of reality. So far, most of these movements still operate separately and have not yet recognized how their intentions interrelate. The purpose of this book is to provide a coherent conceptual framework that will help them recognize the communality of their aims. Once this happens, we can expect the various movements to flow together and form a powerful force for social change. The gravity and global extent of our current crisis indicate that this change is likely to result in a transformation of unprecedented dimensions, a turning point for the planet as a whole."
"At the beginning of the last two decades of our century, we find ourselves in a state of profound, world-wide crisis. It is a complex, multi-dimensional crisis whose facets touch every aspect of our lives – our health and livelihood, the quality of our environment and our social relationships, our economy, technology, and politics. It is a crisis of intellectual, moral, and spiritual dimensions; a crisis of a scale and urgency unprecedented in recorded human history. For the first time we have to face the very real threat of extinction of the human race and of all life on this planet."
"My main professional interest during the 1970s has been in the dramatic change of concepts and ideas that has occurred in physics during the first three decades of the century, and that is still being elaborated in our current theories of matter. The new concepts in physics have brought about a profound change in our world view; from the mechanistic conception of Descartes and Newton to a holistic and ecological view, a view which I have found to be similar to the views of mystics of all ages and traditions."
