But modern times have forced the world’s tribes into a shared space, resulting in epic clashes of values along with unprecedented opportunities. As the world shrinks, the moral lines that divide us become more salient and more puzzling. We fight over everything from tax codes to gay marriage to global warming, and we wonder where, if at all, we can find our common ground. A grand synthesis of neuroscience, psychology, and philosophy, Moral Tribes reveals the underlying causes of modern conflict and lights the way forward. Greene compares the human brain to a dual-mode camera, with point-and-shoot automatic settings (“portrait,” “landscape”) as well as a manual mode. Our point-and-shoot settings are our emotions—efficient, automated programs honed by evolution, culture, and personal experience. The brain’s manual mode is its capacity for deliberate reasoning, which makes our thinking flexible. Point-and-shoot emotions make us social animals, turning Me into Us. But they also make us tribal animals, turning Us against Them. Our tribal emotions make us fight—sometimes with bombs, sometimes with words—often with life-and-death stakes. An award-winning teacher and scientist, Greene directs Harvard University’s Moral Cognition Lab, which uses cutting-edge neuroscience and cognitive techniques to understand how people really make moral decisions. Combining insights from the lab with lessons from decades of social science and centuries of philosophy, the great question of Moral Tribes is this: How can we get along with Them when what they want feels so wrong to Us? Ultimately, Greene offers a set of maxims for navigating the modern moral terrain, a practical road map for solving problems and living better lives. Moral Tribes shows us when to trust our instincts, when to reason, and how the right kind of reasoning can move us forward. A major achievement from a rising star in a new scientific field, Moral Tribes will refashion your deepest beliefs about how moral thinking works and how it can work better.

    Sapolsky's storytelling concept is delightful but it also has a powerful intrinsic logic: he starts by looking at the factors that bear on a person's reaction in the precise moment a behavior occurs, and then hops back in time from there, in stages, ultimately ending up at the deep history of our species and its evolutionary legacy.And so the first category of explanation is the neurobiological one. A behavior occurs--whether an example of humans at our best, worst, or somewhere in between. What went on in a person's brain a second before the behavior happened? Then Sapolsky pulls out to a slightly larger field of vision, a little earlier in time: What sight, sound, or smell caused the nervous system to produce that behavior? And then, what hormones acted hours to days earlier to change how responsive that individual is to the stimuli that triggered the nervous system? By now he has increased our field of vision so that we are thinking about neurobiology and the sensory world of our environment and endocrinology in trying to explain what happened.Sapolsky keeps going: How was that behavior influenced by structural changes in the nervous system over the preceding months, by that person's adolescence, childhood, fetal life, and then back to his or her genetic makeup? Finally, he expands the view to encompass factors larger than one individual. How did culture shape that individual's group, what ecological factors millennia old formed that culture? And on and on, back to evolutionary factors millions of years old.The result is one of the most dazzling tours d'horizon of the science of human behavior ever attempted, a majestic synthesis that harvests cutting-edge research across a range of disciplines to provide a subtle and nuanced perspective on why we ultimately do the things we do...for good and for ill. Sapolsky builds on this understanding to wrestle with some of our deepest and thorniest questions relating to tribalism and xenophobia, hierarchy and competition, morality and free will, and war and peace. Wise, humane, often very funny, Behave is a towering achievement, powerfully humanizing, and downright heroic in its own right.

    Finding this natural basis of life has proved elusive, but in the eloquent and creative Into the Cool, Eric D. Schneider and Dorion Sagan look for answers in a surprising place: the second law of thermodynamics. This second law refers to energy's inevitable tendency to change from being concentrated in one place to becoming spread out over time. In this scientific tour de force, Schneider and Sagan show how the second law is behind evolution, ecology,economics, and even life's origin.Working from the precept that "nature abhors a gradient," Into the Cool details how complex systems emerge, enlarge, and reproduce in a world tending toward disorder. From hurricanes here to life on other worlds, from human evolution to the systems humans have created, this pervasive pull toward equilibrium governs life at its molecular base and at its peak in the elaborate structures of living complex systems. Schneider and Sagan organize their argument in a highly accessible manner, moving from descriptions of the basic physics behind energy flow to the organization of complex systems to the role of energy in life to the final section, which applies their concept of energy flow to politics, economics, and even human health.A book that needs to be grappled with by all those who wonder at the organizing principles of existence, Into the Cool will appeal to both humanists and scientists. If Charles Darwin shook the world by showing the common ancestry of all life, so Into the Cool has a similar power to disturb—and delight—by showing the common roots in energy flow of all complex, organized, and naturally functioning systems.“Whether one is considering the difference between heat and cold or between inflated prices and market values, Schneider and Sagan argue, we can apply insights from thermodynamics and entropy to understand how systems tend toward equilibrium. The result is an impressive work that ranges across disciplinary boundaries and draws from disparate literatures without blinking.”—Publishers Weekly

    If reason is so useful, why didn't it also evolve in other animals? If reason is that reliable, why do we produce so much thoroughly reasoned nonsense? In their groundbreaking account of the evolution and workings of reason, Hugo Mercier and Dan Sperber set out to solve this double enigma. Reason, they argue with a compelling mix of real-life and experimental evidence, is not geared to solitary use, to arriving at better beliefs and decisions on our own. What reason does, rather, is help us justify our beliefs and actions to others, convince them through argumentation, and evaluate the justifications and arguments that others address to us.In other words, reason helps humans better exploit their uniquely rich social environment. This interactionist interpretation explains why reason may have evolved and how it fits with other cognitive mechanisms. It makes sense of strengths and weaknesses that have long puzzled philosophers and psychologists--why reason is biased in favor of what we already believe, why it may lead to terrible ideas and yet is indispensable to spreading good ones.Ambitious, provocative, and entertaining, The Enigma of Reason will spark debate among psychologists and philosophers, and make many reasonable people rethink their own thinking.

    After the Ice is the story of this momentous period--one in which a seemingly minor alteration in temperature could presage anything from the spread of lush woodland to the coming of apocalyptic floods--and one in which we find the origins of civilization itself.Drawing on the latest research in archaeology, human genetics, and environmental science, After the Ice takes the reader on a sweeping tour of 15,000 years of human history. Steven Mithen brings this world to life through the eyes of an imaginary modern traveler--John Lubbock, namesake of the great Victorian polymath and author of Prehistoric Times. With Lubbock, readers visit and observe communities and landscapes, experiencing prehistoric life--from aboriginal hunting parties in Tasmania, to the corralling of wild sheep in the central Sahara, to the efforts of the Guila Naquitz people in Oaxaca to combat drought with agricultural innovations.Part history, part science, part time travel, After the Ice offers an evocative and uniquely compelling portrayal of diverse cultures, lives, and landscapes that laid the foundations of the modern world.

    This fascinating book showcases hundreds of eye-catching tattoos that pay tribute to various scientific disciplines, from evolutionary biology and neuroscience to mathematics and astrophysics, and reveals the stories of the individuals who chose to inscribe their obsessions in their skin. Best of all, each tattoo provides a leaping-off point for bestselling essayist and lecturer Zimmer to reflect on the science in question, whether it's the importance of an image of Darwin's finches or the significance of the uranium atom inked into the chest of a young radiologist.

    Arguing that the processes creating the technium are akin to those of biological evolution, Kelly devotes the opening sections of his exposition to that analogy, maintaining that the technium exhibits a similar tendency toward self-organizing complexity. Having defined the technium, Kelly addresses its discontents, as expressed by the Unabomber (although Kelly admits to trepidation in taking seriously the antitechnology screeds of a murderer) and then as lived by the allegedly technophobic Amish. From his observations and discussions with some Amish people, Kelly extracts some precepts of their attitudes toward gadgets, suggesting folk in the secular world can benefit from the Amish approach of treating tools as servants of self and society rather than as out-of-control masters. Exploring ramifications of technology on human welfare and achievement, Kelly arrives at an optimistic outlook that will interest many, coming, as it does, from the former editor of Wired magazine."Gilbert Taylor, Booklist

    

    It is an integral part of their marriage, child rearing, and community. In this daring new book, distinguished philosopher Daniel C. Dennett takes a hard look at this phenomenon and asks why. Where does our devotion to God come from and what purpose does it serve? Is religion a blind evolutionary compulsion or a rational choice? In "Breaking the Spell," Dennett argues that the time has come to shed the light of science on the fundamental questions of faith. In a spirited narrative that ranges widely through history, philosophy, and psychology, Dennett explores how organized religion evolved from folk beliefs and why it is such a potent force today. Deftly and lucidly, he contends that the "belief in belief" has fogged any attempt to rationally consider the existence of God and the relationship between divinity and human need."Breaking the Spell" is not an antireligious screed but rather an eyeopening exploration of the role that belief plays in our lives, our interactions, and our country. With the gulf between rationalists and adherents of "intelligent design" widening daily, Dennett has written a timely and provocative book that will be read and passionately debated by believers and nonbelievers alike.

    Richard Dawkins, Sam Harris, Daniel Dennett, and Christopher Hitchens have dominated bestseller lists with books denigrating religious belief as dangerous foolishness. And these authors are merely the leading edge of a far larger movement–one that now includes much of the scientific community.“The attack on traditional religious thought,” writes David Berlinski in The Devil’s Delusion, “marks the consolidation in our time of science as the single system of belief in which rational men and women might place their faith, and if not their faith, then certainly their devotion.”A secular Jew, Berlinski nonetheless delivers a biting defense of religious thought. An acclaimed author who has spent his career writing about mathematics and the sciences, he turns the scientific community’s cherished skepticism back on itself, daring to ask and answer some rather embarrassing questions:Has anyone provided a proof of God’s inexistence?Not even close.Has quantum cosmology explained the emergence of the universe or why it is here?Not even close.Have the sciences explained why our universe seems to be fine-tuned to allow for the existence of life?Not even close.Are physicists and biologists willing to believe in anything so long as it is not religious thought?Close enough.Has rationalism in moral thought provided us with an understanding of what is good, what is right, and what is moral?Not close enough.Has secularism in the terrible twentieth century been a force for good?Not even close to being close.Is there a narrow and oppressive orthodoxy of thought and opinion within the sciences?Close enough.Does anything in the sciences or in their philosophy justify the claim that religious belief is irrational?Not even ballpark.Is scientific atheism a frivolous exercise in intellectual contempt?Dead on.Berlinski does not dismiss the achievements of western science. The great physical theories, he observes, are among the treasures of the human race. But they do nothing to answer the questions that religion asks, and they fail to offer a coherent description of the cosmos or the methods by which it might be investigated.This brilliant, incisive, and funny book explores the limits of science and the pretensions of those who insist it can be–indeed must be–the ultimate touchstone for understanding our world and ourselves.From the Hardcover edition.

    Now Wright attempts something even more ambitious: explaining the direction of evolution and human history–and discerning where history will lead us next.In Nonzero: The Logic of Human Destiny, Wright asserts that, ever since the primordial ooze, life has followed a basic pattern. Organisms and human societies alike have grown more complex by mastering the challenges of internal cooperation. Wright's narrative ranges from fossilized bacteria to vampire bats, from stone-age villages to the World Trade Organization, uncovering such surprises as the benefits of barbarian hordes and the useful stability of feudalism. Here is history endowed with moral significance–a way of looking at our biological and cultural evolution that suggests, refreshingly, that human morality has improved over time, and that our instinct to discover meaning may itself serve a higher purpose. Insightful, witty, profound, Nonzero offers breathtaking implications for what we believe and how we adapt to technology's ongoing transformation of the world.From the Trade Paperback edition.

    . . when it comes to the legacy of this country's war on drugs, we should all share his outrage." --The New York Times Book Review From one of the world's foremost experts on the subject, a powerful argument that the greatest damage from drugs flows from their being illegal, and a hopeful reckoning with the possibility of their use as part of a responsible and happy lifeDr. Carl L. Hart, Ziff Professor at Columbia University and former chair of the Department of Psychology, is one of the world's preeminent experts on the effects of so-called recreational drugs on the human mind and body. Dr. Hart is open about the fact that he uses drugs himself, in a happy balance with the rest of his full and productive life as a colleague, husband, father, and friend. In Drug Use for Grown-Ups, he draws on decades of research and his own personal experience to argue definitively that the criminalization and demonization of drug use--not drugs themselves--have been a tremendous scourge on America, not least in reinforcing this country's enduring structural racism.Dr. Hart did not always have this view. He came of age in one of Miami's most troubled neighborhoods at a time when many ills were being laid at the door of crack cocaine. His initial work as a researcher was aimed at proving that drug use caused bad outcomes. But one problem kept cropping up: the evidence from his research did not support his hypothesis. From inside the massively well-funded research arm of the American war on drugs, he saw how the facts did not support the ideology. The truth was dismissed and distorted in order to keep fear and outrage stoked, the funds rolling in, and Black and brown bodies behind bars.Drug Use for Grown-Ups will be controversial, to be sure: the propaganda war, Dr. Hart argues, has been tremendously effective. Imagine if the only subject of any discussion about driving automobiles was fatal car crashes. Drug Use for Grown-Ups offers a radically different vision: when used responsibly, drugs can enrich and enhance our lives. We have a long way to go, but the vital conversation this book will generate is an extraordinarily important step.
