"People often ask, "What is the single most important environmental/population problem facing the world today?" A flip answer would be, "The single most important problem is our misguided focus on identifying the single most important problem!""
"History, as well as life itself, is complicated; neither life nor history is an enterprise for those who seek simplicity and consistency."
"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."
"Behavior evolves through natural selection, just as anatomy does. Hence if sex is enjoyable, natural selection must have been responsible for that outcome."
"Perhaps our greatest distinction as a species is our capacity, unique among animals, to make counter-evolutionary choices."
"Our sex is ultimately laid down by our genes."
"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."
"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."
"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."
"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."
"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."
"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."
"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?"
"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."
"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."
"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."
"Put another way, the chimpanzees' closest relative is not the gorilla but humans."
"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."
"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."
"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."
"My hope in writing this book has been that enough people will choose to profit from that opportunity to make a difference."
"Remember that impact is the product of two factors: population multiplied times impact per person."
"What are the choices that we must make if we are now to succeed, and not to fail? [...] Two types of choices seem to me to have been crucial to tipping their outcomes towards success or failure: long-term planning, and willingness to reconsider core values. On reflection, we can also recognize the crucial role of these same two choices for the outcomes of our individual lives. One of those choices has depended on the courage to practice long-term thinking, and to make bold, courageous, anticipatory decisions at a time when problems have become perceptible but before they have reached crisis proportions. [...] The other crucial choice illuminated by the past involves the courage to make painful decisions about values. Which of the values that formerly served a society well can continue to be maintained under new changed circumstances? Which of these treasured values must instead be jettisoned and replaced with different approaches?"
"Because we are the cause of our environmental problems, we are the ones in control of them, and we can choose or not choose to stop causing them and start solving them. The future is up for grabs, lying in our own hands. We don’t need new technologies to solve our problems; while new technologies can make some contribution, for the most part we "just" need the political will to apply solutions already available."
"If the Easter Islanders couldn't solve their milder local problems in the past, how can the modern world hope to solve its big global problems? People who get depressed at such thoughts often then ask me, “Jared, are you optimistic or pessimistic about the world’s future?” I answer, “I am a cautious optimist.” By that, I mean that, on the one hand, I acknowledge the seriousness of the problems facing us. If we don’t make a determined effort to solve them, and if we don’t succeed at that effort, the world as a whole within the next few decades will face a declining standard of living, or perhaps something worse. That’s the reason why I decided to devote most of my career efforts at this stage of my life to convincing people that our problems have to be taken seriously and won’t go away otherwise. On the other hand, we shall be able to solve our problems – if we choose to do so."
"In fact, one of the main lesson to be learned from the collapses of the Maya, Anasazi, Easter Islanders, and those other past societies (as well as from the recent collapse of the Soviet Union) is that a society's steep decline may begin only a decade or two after the society reaches its peak numbers, wealth, and power. [...] The reason is simple: maximum population, wealth, resource consumption, and waste production mean maximum environmental impact, approaching the limit where impact outstrips resources. On reflection, it's no surprise that declines of societies tend to follow swiftly on their peaks."
""The environment has to be balanced against the economy." This quote portrays environmental concerns as a luxury, views measures to solve environmental problems as incurring a net cost, and considers leaving environmental problems unsolved to be a money-saving device. This one-liner puts the truth exactly backwards. Environmental messes cost us huge sums of money both in the short run and in the long run; cleaning up or preventing those messes saves us huge sums in the long run, and often in the short run as well. In caring for the health of our surroundings, just as of our bodies, it is cheaper and preferable to avoid getting sick than to try to cure illnesses after they have developed."
"Thus, because we are rapidly advancing along this non-sustainable course, the world's environmental problems will get resolved, in one way or another, within the lifetimes of the children and young adults alive today The only question is whether they will become resolved in pleasant ways of our own choice, or in unpleasant ways not of our choice, such as warfare, genocide, starvation, disease epidemics, and collapses of societies. While all of those grim phenomena have been endemic to humanity throughout our history, their frequency increases with environmental degradation, population pressure, and the resulting poverty and political instability."
"Those numbers may not sound like a big deal until one reflects that average global temperatures were "only" 5 degrees cooler at the height of the last Ice Age."
"Businesses have changed when the public came to expect and require different behavior, to reward businesses for behavior that the public wanted, and to make things difficult for businesses practising behaviors that the public didn't want. I predict that in the future, just as in the past, changes in public attitudes will be essential for changes in businesses' environmental practices."
"I didn't add any new elements [to the modern synthetic theory] to speak of. I just modified things so that people could understand how things were in the plant world."
"[His photography was a] guiding force for visual interpretation [of Schindler's List]."
"I met him in 1966, and discovered how undiscovered he was. -- Cornell Capa"
"Those images have proved to be an extraordinary record, made with forebodings of misfortune, that bring alive the flavor of the shtetl, of a Jewish peasant tending geese in the Carpathian Mountains, of tumbledown shacks in the Jewish quarter of Lublin, Poland, of Jewish patriarchs, in long caftans and wearing the furry hat called a shtreimel, trudging through the snow. -- Shepard, Richard"
"[Roman Vishniac is] the official mortuary photographer of Eastern European Jewry. -- Leon Wieseltier, editor of The New Republic"
"[his scientific accomplishments] were overshadowed by the photographs he took of Jews in prewar Eastern Europe and in Nazi Berlin. -- Shepard, Richard"
"In addition to his charisma and obvious talents, he was also known to possess what Howard Greenberg, Vishniac’s longtime gallerist, identified as “one of the bigger egos on the planet.”"
"Vishniac came back from his trips... with a collection of photographs that has become an important historical document, for it gives us a last minute look at the human beings he photographed just before the fury of the Nazi brutality exterminated them. Vishniac took with him on this self-imposed assignment... a rare depth of understanding and a native son's warmth and love for his people. ~ Edward Steichen, ex-director of photography at the Museum of Modern Art, in the 1950s."
"“No one who hasn’t tried it can comprehend the careful planning, the diabolical perseverance and the incredible skill it takes to obtain the [photomicroscopic] results he gets,” the magazine quoted Philippe Halsman, former president of the American Society of Magazine Photographers, as saying of Vishniac. “The man is a special kind of genius.”"
"Concentration camp money... It was a German sadism that invented it. Can you do anything with it? Yes, you can cry."
"Even before the concentration camps, I felt it was my duty to my ancestors to preserve a world which might cease to exist."
"You can't teach biology with a bottle containing dead animals and organisms."
"My friends assured me that Hitler’s talk was sheer bombast,” Vishniac said in 1955. “But I replied that he would not hesitate to exterminate those people when he got around to it. And who was there to defend them? I knew I could be of little help, but I decided that, as a Jew, it was my duty to my ancestors, who grew up among the very people who were being threatened, to preserve — in pictures, at least — a world that might soon cease to exist."
"[The Jews who roamed through Moscow looking for work] had a special kind of face ... a special kind of whisper and a special kind of footstep ... They were like hunted animals."
"These are the faces of children I embraced and kissed and loved. I cannot imagine that they are dead, that none would survive... A million and a half children among the six million... But this I knew... I wanted to save their faces, not their ashes."
"I read the first edition of 'Mein Kampf' when it came out in 1923 and even then I knew Hitler meant what he said. I knew the history of anti-Semitism going back for centuries, and I knew all about pogroms in Russia and Eastern Europe. When I grew up and whent to school in Moscow, I experienced anti-Semitism and the restrictions on where Jews could live and work. Hitler systemized anti-Semitism. Pogroms are my business... Oh yes, I could be a professor of anti-Semitism."
"The purpose of photography is the transmission of a visualized sector of life through the medium of the camera into a mental process that starts with the photographer's thinking about the subject he photographs and is continued in the mind of the spectator."
"Nature, God, or whatever you want to call the creator of the universe comes through the microscope clearly and strongly"
"...can you call a farm with a dozen geese a farm? Still, it was a little better for the Jews in Czechoslovakia. There were only two pogroms there. What's two pogroms?"
"The Jews of the shtetls that Tolstoy remembered were saints... the people I photographed were saints. So now, in 1983, I tell the world: When you learn about Goethe, don't forget to study the Holocaust, too."
