Fukuyama sketches a brief history of man's changing understanding of human nature: from Plato and Aristotle to the modernity's utopians and dictators who sought to remake mankind for ideological ends. Fukuyama argues that the ability to manipulate the DNA of all of one person's descendants will have profound, and potentially terrible, consequences for our political order, even if undertaken with the best of intentions. In Our Posthuman Future, one of our greatest social philosophers begins to describe the potential effects of genetic exploration on the foundation of liberal democracy: the belief that human beings are equal by nature.

    We cannot choose to avoid philosophy, we can only choose whether we understand it or not. Stefan Molyneux, host of Freedomain Radio – the largest and most popular philosophy show in the world, with over 600 million views and downloads – takes you on a spectacular journey through the most foundational philosophical questions of the ages, clearing up and clarifying the most thorny problems posed by philosophers throughout history: -How do we know what is real? -How do we know what is true? -How do we know what is right? -How do we know what is good? -How do we know we even have a choice? -How do we convince others? These are all questions that we – as individuals and societies – wrestle with every day. These questions have challenged, motivated and plagued mankind for thousands of years. “Essential Philosophy” answers these questions with rigourous, illuminating and entertaining logic, reasoning from deep first principles to spectacular final conclusions. There is no need for confusion, there is no need for despair, there is no need for fear – pick up this book now, absorb the true power of philosophy, and live a rational moral life to the fullest. And then, give “Essential Philosophy” to others, so that the world may one day live in reason and peace.

    Written for both the casual reader and the science buff hungry for new information, The Vision Revolution is a resource that dispels commonly believed perceptions about sight and offers answers drawn from the field’s most recent research.Changizi focuses on four “why” questions:1. Why do we see in color?2. Why do our eyes face forward?3. Why do we see illusions?4. Why does reading come so naturally to us?Why Do We See in Color?It was commonly believed that color vision evolved to help our primitive ancestors identify ripe fruit. Changizi says we should look closer to home: ourselves. Human color vision evolved to give us greater insights into the mental states and health of other people. People who can see color changes in skin have an advantage over their color-blind counterparts; they can see when people are blushing with embarrassment, purple-faced with exertion or the reddening of rashes. Changizi’s research reveals that the cones in our eyes that allow us to see color are exquisitely designed exactly for seeing color changes in the skin. And it’s no coincidence that the primates with color vision are the ones with bare spots on their faces and other body parts; Changizi shows that the development of color vision in higher primates closely parallels the loss of facial hair, culminating in the near hairlessness and highly developed color vision of humans.Why Do Our Eyes Face Forward?Forward-facing eyes set us apart from most mammals, and there is much dispute as to why we have them. While some speculate that we evolved this feature to give us depth perception available through stereo vision, this type of vision only allows us to see short distances, and we already have other mechanisms that help us to estimate distance. Changizi’s research shows that with two forward-facing eyes, primates and humans have an x-ray ability. Specifically, we’re able to see through the cluttered leaves of the forest environment in which we evolved. This feature helps primates see their targets in a crowded, encroached environment. To see how this works, hold a finger in front of your eyes. You’ll find that you’re able to look “through” it, at what is beyond your finger. One of the most amazing feats of two forward-facing eyes? Our views aren’t blocked by our noses, beaks, etc.Why Do We See Illusions?We evolved to see moving objects, not where they are, but where they are going to be. Without this ability, we couldn’t catch a ball because the brain’s ability to process visual information isn’t fast enough to allow us to put our hands in the right place to intersect for a rapidly approaching baseball. “If our brains simply created a perception of the way the world was at the time light hit the eye, then by the time that perception was elicited—which takes about a tenth of a second for the brain to do—time would have marched on, and the perception would be of the recent past,” Changizi explains. Simply put, illusions occur when our brain is tricked into thinking that a stationary two-dimensional picture has an element that is moving. Our brains project the “moving” element into the future and, as a result, we don’t see what’s on the page, but what our brain thinks will be the case a fraction of a second into the future.Why Does Reading Come So Naturally to Us?We can read faster than we can hear, which is odd, considering that reading is relatively recent, and we’ve evolved to process speech for millions of years. Changizi’s research reveals that language has been carefully designed to tap in to elements of the visual processing center that have evolved for tens of millions of years. Visual signs of all languages are shaped like objects in nature, Changizi says, because we have evolved to see nature easily. “People have noticed letters in nature for some time, and there are artists who have a spent a lot of time photographing Latin letters in natural scenes or on butterfly wings,” Changizi says. “For example, if you look at an upper corner of the room you are in, you will see three contours meeting at a point, making a shape close to that of a ‘Y.’“ The Vision Revolution expands upon how our ancestors found the shapes of Latin letters and delves into how visual signs can have similar shapes even though their inspirations come from very different environments.In addition to these four areas, The Vision Revolution explores other phenomena such as cyclopses, peeking and many more you hadn’t even thought to wonder about. Changizi shows how deeply involved these evolutionary aspects of our vision are in why we see the way we do—and what the future holds for us.“…to understand how culture interacts with vision, one must understand not just the eye’s design, but the actual mechanisms we have evolved,” Changizi says, “for culture can tap in to both the designed responses of our brains and the unintended responses.”The Vision Revolution is a book that finally gives attention to what before has been largely neglected by other works on human vision—a book that looks at the “why.”

    Michael Baden's first-person, no-holds-barred account of his distinguished career in forensic pathology. In determining the causes of tens of thousands of deaths, from those of presidents and rock stars to victims of serial killings, exotic sex rituals, mass disasters, child abuse and drug abuse, Baden has come to the unavoidable conclusion that the search for scientific truth is often sullied by the pressures of expediency. He produces dramatic evidence to demonstrate that political intrigue, influence peddling, and professional incompetence have created a national crisis in forensic medicine.

    But things didn't turn out that way. For a start, we turned out to have far fewer genes than originally thought - just over 20,000, the same sort of number as a fruit fly or worm. What's more, the proportionof DNA consisting of genes coding for proteins was a mere 2%. So, was the rest of the genome accumulated 'junk'?Things have changed since those early heady days of the Human Genome Project. But the emerging picture is if anything far more exciting. In this book, John Parrington explains the key features that are coming to light - some, such as the results of the international ENCODE programme, still much debated and controversial in their scope. He gives an outline of the deeper genome, involving layers of regulatory elements controlling and coordinating the switching on and off of genes; the impact ofits 3D geometry; the discovery of a variety of new RNAs playing critical roles; the epigenetic changes influenced by the environment and life experiences that can make identical twins different and be passed on to the next generation; and the clues coming out of comparisons with the genomes ofNeanderthals as well as that of chimps about the development our species. We are learning more about ourselves, and about the genetic aspects of many diseases. But in its complexity, flexibility, and ability to respond to environmental cues, the human genome is proving to be far more subtle than we ever imagined.

    Supersized life spans are going to radically alter society, and present an unprecedented opportunity to change our approach not only to old age but to all of life’s stages. The ramifications are just beginning to dawn on us.... yet in the meantime, we keep thinking about, and planning for, life as it used to be lived. In A Long Bright Future, longevity and aging expert Laura Carstensen guides us into the new possibilities offered by a longer life. She debunks the myths and misconceptions about aging that stop us from adequately preparing for the future both as individuals and as a society: that growing older is associated with loneliness and unhappiness, and that only the genetically blessed live well and long. She then focuses on other important components of a long life, including finances, health, social relationships, Medicare and Social Security, challenging our preconceived notions of “old age” every step of the way.

    However, in a country of more than 325 million people, addressing everyone's issues is challenging. How can we effect beneficial change for everyone so we all can thrive? What is the great equalizer?In this book, Daniel E. Dawes argues that political determinants of health create the social drivers--including poor environmental conditions, inadequate transportation, unsafe neighborhoods, and lack of healthy food options--that affect all other dynamics of health. By understanding these determinants, their origins, and their impact on the equitable distribution of opportunities and resources, we will be better equipped to develop and implement actionable solutions to close the health gap.Dawes draws on his firsthand experience helping to shape major federal policies, including the Affordable Care Act, to describe the history of efforts to address the political determinants that have resulted in health inequities. Taking us further upstream to the underlying source of the causes of inequities, Dawes examines the political decisions that lead to our social conditions, makes the social determinants of health more accessible, and provides a playbook for how we can address them effectively. A thought-provoking and evocative account that considers both the policies we think of as health policy and those that we don't, The Political Determinants of Health provides a novel, multidisciplinary framework for addressing the systemic barriers preventing the United States from becoming the healthiest nation in the world.

    It follows that the belief that there is a significant chance that we will one day become posthumans who run ancestor-simulations is false, unless we are currently living in a simulation. A number of other consequences of this result are also discussed.

    Bernard Haisch contends that there is a purpose and an underlying intelligence behind the Universe, one that is consistent with modern science, especially the Big Bang and evolution. It is based on recent discoveries that there are numerous coincidences and fine-tunings of the laws of nature that seem extraordinarily unlikely.A more rational concept of God is called for. As astrophysicist Sir James Jeans wrote, "the Universe begins to look more like a great thought than like a great machine."Despite bestsellers by Christopher Hitchens, Richard Dawkins, and Sam Harris that have denounced the evils of religion and proclaimed that science has shown that there is no God, The Purpose-Guided Universe shows how one can believe in God and science.

    But Maurice Hilleman came close. Maurice Hilleman is the father of modern vaccines. Chief among his accomplishments are nine vaccines that practically every child gets, rendering formerly deadly diseases — including mumps, rubella, and measles — nearly forgotten. Author Paul A. Offit's rich and lively narrative details Hilleman's research and experiences as the basis for a larger exploration of the development of vaccines, covering two hundred years of medical history and traveling across the globe in the process. The history of vaccines necessarily brings with it a cautionary message, as they have come under assault from those insisting they do more harm than good. Paul Offit clearly and compellingly rebuts these arguments, and, by demonstrating how much the work of Hilleman and others has gained for humanity, shows us how much we have to lose.
