“A landmark book in the science of emotions and its implications for ethics and human universals.”—Library Journal, starred review In this startling study of human emotion, Dacher Keltner investigates an unanswered question of human evolution: If humans are hardwired to lead lives that are “nasty, brutish, and short,” why have we evolved with positive emotions like gratitude, amusement, awe, and compassion that promote ethical action and cooperative societies? Illustrated with more than fifty photographs of human emotions, Born to Be Good takes us on a journey through scientific discovery, personal narrative, and Eastern philosophy. Positive emotions, Keltner finds, lie at the core of human nature and shape our everyday behavior—and they just may be the key to understanding how we can live our lives better.

Africa does not give up its secrets easily. Buried there lie answers about the origins of humankind and the dawn of civilisation. Through a century of archaeological investigation, scientists have transformed our understanding of the beginnings of human life, although vital clues still remain hidden. In Born in Africa, Martin Meredith follows the trail of discoveries about our human origins made by scientists over the last hundred years, as well as describing the history of scholarship in this incredibly exciting field. He relates the intense rivalries, personal feuds and fierce controversies that shaped the study and perception of Africa, and recounts the feats of skill and endurance that have illuminated thousands of years of human evolution. The results have been momentous. Scientists have identified more than twenty species of extinct humans and firmly established Africa as the birthplace not only of humankind, but also of our own species: homo sapiens, the modern human. Scientific study has revealed how early technology, language ability and artistic endeavour all originated in Africa, and scientists have shown how, in an exodus sixty thousand years ago, small groups of Africans left their birthplace to populate the rest of the world. We all have an African legacy, and in this fascinating and informative book Martin Meredith leads us back to the place where we have rediscovered our common human heritage.

“According to the words of Phaedrus in the Symposium of Plato, Love, sometimes named Eros, has no parents, no age, no history, and its origin remains unknown to anyone. Love, whose destiny is said to be unique amongst the gods and humans, perhaps embodies desire for a conjunction always in search of its happening. Love would represent a dynamism longing for the copula incarnating the transcendence of our being. As such, Love would remain the everlasting yearning for the accomplishment of the ecstatic destiny of humanity.” In this book, Luce Irigaray - philosopher, linguist, psychologist and psychoanalyst - proposes nothing less than a new way of conceiving what a human being is as well as a means to ensure our individual and relational development from birth. Unveiling the mystery of our origin is probably what most motivates our quests and plans. And yet such a disclosure proves to be impossible. Indeed we were born as one from a union between two, and we are forever deprived of an origin of our own. Hence our ceaseless search for roots: in our genealogy, in the place where we were born, in our culture, religion or language. But a human being cannot develop from its own roots as a tree does. As humans, we must take responsibility for our own being and existence without any given continuity with our origin and background. How can we achieve that? First by cultivating our breathing, which is more than a means to come into the world and to exist; breathing also allows us to transcend mere survival to secure for ourselves a spiritual becoming. Taking on our sexuate belonging is the second element which enables us to assume our natural existence. Indeed, this determination at once brings us energy and provides us with a structure which contributes to our individuation and our relations with other living beings and the world. Our sexuation can compensate for our absence of roots too by compelling us to unite with the other sex so that we freely approach the copulative conjunction from which we were born; that is, the mystery of our origin. This does not occur through a mere sexual instinct or drive, but requires us to cultivate desire and love with respect for our mutual difference(s). In this way we can give rise to a new human being, not only at a natural but also at an ontological level.

“If you’ve been looking for something different to level up your health, fitness, and personal growth, this is it.”—Melissa Urban, Whole30 CEO and New York Times bestselling author of The Book of Boundaries “Michael Easter’s genius is that he puts data around the edges of what we intuitively believe. His work has inspired many to change their lives for the better.”—Dr. Peter Attia, #1 New York Times bestselling author of Outlive Discover the evolutionary mind and body benefits of living at the edges of your comfort zone and reconnecting with the wild—from the author of Scarcity Brain, coming in September! In many ways, we’re more comfortable than ever before. But could our sheltered, temperature-controlled, overfed, underchallenged lives actually be the leading cause of many our most urgent physical and mental health issues? In this gripping investigation, award-winning journalist Michael Easter seeks out off-the-grid visionaries, disruptive genius researchers, and mind-body conditioning trailblazers who are unlocking the life-enhancing secrets of a counterintuitive solution: discomfort. Easter’s journey to understand our evolutionary need to be challenged takes him to meet the NBA’s top exercise scientist, who uses an ancient Japanese practice to build championship athletes; to the mystical country of Bhutan, where an Oxford economist and Buddhist leader are showing the world what death can teach us about happiness; to the outdoor lab of a young neuroscientist who’s found that nature tests our physical and mental endurance in ways that expand creativity while taming burnout and anxiety; to the remote Alaskan backcountry on a demanding thirty-three-day hunting expedition to experience the rewilding secrets of one of the last rugged places on Earth; and more. Along the way, Easter uncovers a blueprint for leveraging the power of discomfort that will dramatically improve our health and happiness, and perhaps even help us understand what it means to be human. The Comfort Crisis is a bold call to break out of your comfort zone and explore the wild within yourself.

The fight against child mortality that transformed parenting, doctoring, and the way we live. Only one hundred years ago, in even the world’s wealthiest nations, children died in great numbers—of diarrhea, diphtheria, and measles, of scarlet fever and tuberculosis. Throughout history, culture has been shaped by these deaths; diaries and letters recorded them, and writers such as Louisa May Alcott, W. E. B. Du Bois, and Eugene O’Neill wrote about and mourned them. Not even the powerful and the wealthy could escape: of Abraham and Mary Lincoln’s four children, only one survived to adulthood, and the first billionaire in history, John D. Rockefeller, lost his beloved grandson to scarlet fever. For children of the poor, immigrants, enslaved people and their descendants, the chances of dying were far worse. The steady beating back of infant and child mortality is one of our greatest human achievements. Interweaving her own experiences as a medical student and doctor, Perri Klass pays tribute to groundbreaking women doctors like Rebecca Lee Crumpler, Mary Putnam Jacobi, and Josephine Baker, and to the nurses, public health advocates, and scientists who brought new approaches and scientific ideas about sanitation and vaccination to families. These scientists, healers, reformers, and parents rewrote the human experience so that—for the first time in human memory—early death is now the exception rather than the rule, bringing about a fundamental transformation in society, culture, and family life.

A revelatory tale of how the human brain develops, from conception to birth and beyond By the time a baby is born, its brain is equipped with billions of intricately crafted neurons wired together through trillions of interconnections to form a compact and breathtakingly efficient supercomputer. Zero to Birth takes you on an extraordinary journey to the very edge of creation, from the moment of an egg’s fertilization through each step of a human brain’s development in the womb—and even a little beyond. As pioneering experimental neurobiologist W. A. Harris guides you through the process of how the brain is built, he takes up the biggest questions that scientists have asked about the developing brain, describing many of the thrilling discoveries that were foundational to our current understanding. He weaves in a remarkable evolutionary story that begins billions of years ago in the Proterozoic eon, when multicellular animals first emerged from single-cell organisms, and reveals how the growth of a fetal brain over nine months reflects the brain’s evolution through the ages. Our brains have much in common with those of other animals, and Harris offers an illuminating look at how comparative animal studies have been crucial to understanding what makes a human brain human. An unforgettable chronicle of one of nature’s greatest achievements, Zero to Birth describes how the brain’s incredible feat of orchestrated growth ensures that every brain is unique, and how breakthroughs at the frontiers of science are helping us to decode many traits that only reveal themselves later in life.

It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.
