But armies have developed sophisticated ways of overcoming this instinctive aversion. And contemporary civilian society, particularly the media, replicates the army's conditioning techniques, and, according to Lt. Col. Dave Grossman's thesis, is responsible for our rising rate of murder among the young.Upon its initial publication, On Killing was hailed as a landmark study of the techniques the military uses to overcome the powerful reluctance to kill, of how killing affects soldiers, and of the societal implications of escalating violence. Now, Grossman has updated this classic work to include information on 21st-century military conflicts, recent trends in crime, suicide bombings, school shootings, and more. The result is a work certain to be relevant and important for decades to come.

    His students, some of the nation’s brightest minds, were adrift when it came to the big questions: how to think critically and creatively, and how to find a sense of purpose.Excellent Sheep takes a sharp look at the high-pressure conveyor belt that begins with parents and counselors who demand perfect grades and culminates in the skewed applications Deresiewicz saw firsthand as a member of Yale’s admissions committee. As schools shift focus from the humanities to "practical" subjects like economics and computer science, students are losing the ability to think in innovative ways. Deresiewicz explains how college should be a time for self-discovery, when students can establish their own values and measures of success, so they can forge their own path. He addresses parents, students, educators, and anyone who's interested in the direction of American society, featuring quotes from real students and graduates he has corresponded with over the years, candidly exposing where the system is broken and clearly presenting solutions.

    While the mathematics is there, the effort is not all concentrated on proofs. Strang's emphasis is on understanding. He explains concepts, rather than deduces. This book is written in an informal and personal style and teaches real mathematics. The gears change in Chapter 2 as students reach the introduction of vector spaces. Throughout the book, the theory is motivated and reinforced by genuine applications, allowing pure mathematicians to teach applied mathematics.

    Rest assured that the book is not mere theory. Ericsson's research focuses on the real world, and he explains in detail, with examples, how all of us can apply the principles of great performance in our work or in any other part of our lives."-- Fortune Anders Ericsson has made a career studying chess champions, violin virtuosos, star athletes, and memory mavens. Peak distills three decades of myth-shattering research into a powerful learning strategy that is fundamentally different from the way people traditionally think about acquiring new abilities. Whether you want to stand out at work, improve your athletic or musical performance, or help your child achieve academic goals, Ericsson's revolutionary methods will show you how to improve at almost any skill that matters to you."The science of excellence can be divided into two eras: before Ericsson and after Ericsson. His groundbreaking work, captured in this brilliantly useful book, provides us with a blueprint for achieving the most important and life-changing work possible: to become a little bit better each day."--Dan Coyle, author of The Talent Code "Ericsson's research has revolutionized how we think about human achievement. If everyone would take the lessons of this book to heart, it could truly change the world."--Joshua Foer, author of Moonwalking with Einstein

    In it, Russell offers a nontechnical, undogmatic account of his philosophical criticism as it relates to arithmetic and logic. Rather than an exhaustive treatment, however, the influential philosopher and mathematician focuses on certain issues of mathematical logic that, to his mind, invalidated much traditional and contemporary philosophy.In dealing with such topics as number, order, relations, limits and continuity, propositional functions, descriptions, and classes, Russell writes in a clear, accessible manner, requiring neither a knowledge of mathematics nor an aptitude for mathematical symbolism. The result is a thought-provoking excursion into the fascinating realm where mathematics and philosophy meet — a philosophical classic that will be welcomed by any thinking person interested in this crucial area of modern thought.

    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.

    Our intellectual capacity, our introversion or extraversion, our vulnerability to mental illness, even whether we are a morning person - all of these aspects of our personality are profoundly shaped by our inherited DNA differences.In Blueprint, Robert Plomin, a pioneer in the field of behavioural genetics, draws on a lifetime's worth of research to make the case that DNA is the most important factor shaping who we are. Our families, schools and the environment around us are important, but they are not as influential as our genes. This is why, he argues, teachers and parents should accept children for who they are, rather than trying to mould them in certain directions. Even the environments we choose and the signal events that impact our lives, from divorce to addiction, are influenced by our genetic predispositions. Now, thanks to the DNA revolution, it is becoming possible to predict who we will become, at birth, from our DNA alone. As Plomin shows us, these developments have sweeping implications for how we think about parenting, education, and social mobility.A game-changing book by a leader in the field, Blueprint shows how the DNA present in the single cell with which we all begin our lives can impact our behaviour as adults.

    Serotonin is the "contentment" neurotransmitter that tells our brains we don't need any more; yet its deficiency leads to depression. Ideally, both are in optimal supply. Yet dopamine evolved to overwhelm serotonin--because our ancestors were more likely to survive if they were constantly motivated--with the result that constant desire can chemically destroy our ability to feel happiness, while sending us down the slippery slope to addiction. In the last forty years, government legislation and subsidies have promoted ever-available temptation (sugar, drugs, social media, porn) combined with constant stress (work, home, money, Internet), with the end result of an unprecedented epidemic of addiction, anxiety, depression, and chronic disease. And with the advent of neuromarketing, corporate America has successfully imprisoned us in an endless loop of desire and consumption from which there is no obvious escape.With his customary wit and incisiveness, Lustig not only reveals the science that drives these states of mind, he points his finger directly at the corporations that helped create this mess, and the government actors who facilitated it, and he offers solutions we can all use in the pursuit of happiness, even in the face of overwhelming opposition. Always fearless and provocative, Lustig marshals a call to action, with seminal implications for our health, our well-being, and our culture.

    Every new reader's brain possesses the extraordinary capacity to rearrange itself beyond its original abilities in order to understand written symbols. But how does the brain learn to read? As world-renowned cognitive neuroscientist and scholar of reading Maryanne Wolf explains in this impassioned book, we taught our brain to read only a few thousand years ago, and in the process changed the intellectual evolution of our species.Wolf tells us that the brain that examined tiny clay tablets in the cuneiform script of the Sumerians is configured differently from the brain that reads alphabets or of one literate in today's technology.There are critical implications to such an evolving brain. Just as writing reduced the need for memory, the proliferation of information and the particular requirements of digital culture may short-circuit some of written language's unique contributions—with potentially profound consequences for our future.Turning her attention to the development of the individual reading brain, Wolf draws on her expertise in dyslexia to investigate what happens when the brain finds it difficult to read. Interweaving her vast knowledge of neuroscience, psychology, literature, and linguistics, Wolf takes the reader from the brains of a pre-literate Homer to a literacy-ambivalent Plato, from an infant listening to Goodnight Moon to an expert reader of Proust, and finally to an often misunderstood child with dyslexia whose gifts may be as real as the challenges he or she faces.As we come to appreciate how the evolution and development of reading have changed the very arrangement of our brain and our intellectual life, we begin to realize with ever greater comprehension that we truly are what we read. Ambitious, provocative, and rich with examples, Proust and the Squid celebrates reading, one of the single most remarkable inventions in history. Once embarked on this magnificent story of the reading brain, you will never again take for granted your ability to absorb the written word.

    How long should it take before you stop having to force it and start doing it automatically?The surprising answers are found in Making Habits, Breaking Habits, a psychologist's popular examination of one of the most powerful and under-appreciated processes in the mind. Although people like to think that they are in control, much of human behavior occurs without any decision-making or conscious thought.Drawing on hundreds of fascinating studies, psychologist Jeremy Dean busts the myths to finally explain why seemingly easy habits, like eating an apple a day, can be surprisingly difficult to form, and how to take charge of your brain's natural “autopilot” to make any change stick.Witty and intriguing, Making Habits, Breaking Habits shows how behavior is more than just a product of what you think. It is possible to bend your habits to your will—and be happier, more creative, and more productive.

    The novel approach taken here banishes determinants to the end of the book and focuses on the central goal of linear algebra: understanding the structure of linear operators on vector spaces. The author has taken unusual care to motivate concepts and to simplify proofs. For example, the book presents - without having defined determinants - a clean proof that every linear operator on a finite-dimensional complex vector space (or an odd-dimensional real vector space) has an eigenvalue. A variety of interesting exercises in each chapter helps students understand and manipulate the objects of linear algebra. This second edition includes a new section on orthogonal projections and minimization problems. The sections on self-adjoint operators, normal operators, and the spectral theorem have been rewritten. New examples and new exercises have been added, several proofs have been simplified, and hundreds of minor improvements have been made throughout the text.

    We're all conspiracy theorists--some of us just hide it better than others.Conspiracy theorists aren't just a handful of people who wear tin-foil hats and have bizarre ideas about shape-shifting reptilian aliens. Conspiracy theories are as likely to appeal to women as to men, college students as to retired professors, middle-class bloggers as to blue-collar workers.Psychological research sheds light on why some people are more drawn to conspiracy thinking, especially when they feel discontented, distrustful, and desire privileged knowledge. But ultimately we are all natural-born conspiracy theorists. Our brains are wired to see patterns and to weave unrelated data points into complex stories. We instinctively see events in the world in terms of human motives and intentions, leading us to discount the role of chance and unintended consequences, and we look for some hidden hand behind catastrophic events. These psychological quirks can lead us to suspect a conspiracy where none exists.Conspiracy theories have existed throughout history, from ancient Athens and Rome to present day theories about 9/11 and who shot JFK. Suspicious Minds explores the phenomenon and reveals the important consequences conspiracy theories can have--from discouraging parents from vaccinating their children against deadly diseases to hampering political policies to combat climate change.

    Rick Strassman conducted US DEA-approved clinical research at the University of New Mexico in which he injected 60 volunteers with DMT, one of the most powerful psychedelics known. His detailed account of those sessions is an inquiry into the nature of the human mind and the therapeutic potential of psychedelics. DMT, a plant-derived chemical that is also manufactured by the human brain, consistently produced near-death and mystical experiences. Many volunteers reported convincing encounters with intelligent nonhuman presences, especially "aliens." Nearly all felt that the sessions were among the most profound experiences of their lives.Strassman's research connects DMT with the pineal gland, considered by Hindus to be the site of the seventh chakra and by René Descartes to be the seat of the soul. DMT: The Spirit Molecule makes the case that DMT, naturally released by the pineal gland, facilitates the soul's movement in and out of the body and is an integral part of the birth and death experiences, as well as the highest states of meditation and even sexual transcendence. Strassman also believes that alien abduction experiences are brought on by accidental releases of DMT. If used wisely, DMT could trigger a period of remarkable progress in the scientific exploration of the most mystical regions of the human mind and soul.
