Casti contemplates an imaginary evening of intellectual inquiry—a sort of “My Dinner with” not Andre, but five of the most brilliant thinkers of the twentieth century.Imagine, if you will, one stormy summer evening in 1949, as novelist and scientist C. P. Snow, Britain’s distinguished wartime science advisor and author of The Two Cultures, invites four singular guests to a sumptuous seven-course dinner at his alma mater, Christ’s College, Cambridge, to discuss one of the emerging scientific issues of the day: Can we build a machine that could duplicate human cognitive processes? The distinguished guest list for Snow’s dinner consists of physicist Erwin Schrodinger, inventor of wave mechanics; Ludwig Wittgenstein, the famous twentieth-century philosopher of language, who posited two completely contradictory theories of human thought in his lifetime; population geneticist/science popularizer J.B.S. Haldane; and Alan Turing, the mathematician/codebreaker who formulated the computing scheme that foreshadowed the logical structure of all modern computers. Capturing not only their unique personalities but also their particular stands on this fascinating issue, Casti dramatically shows what each of these great men might have argued about artificial intelligence, had they actually gathered for dinner that midsummer evening.With Snow acting as referee, a lively intellectual debate unfolds. Philosopher Wittgenstein argues that in order to become conscious, a machine would have to have life experiences similar to those of human beings—such as pain, joy, grief, or pleasure. Biologist Haldane offers the idea that mind is a separate entity from matter, so that regardless of how sophisticated the machine, only flesh can bond with that mysterious force called intelligence. Both physicist Schrodinger and, of course, computer pioneer Turing maintain that it is not the substance, but rather the organization of that substance, that makes a mind conscious.With great verve and skill, Casti recreates a unique and thrilling moment of time in the grand history of scientific ideas. Even readers who have already formed an opinion on artificial intelligence will be forced to reopen their minds on the subject upon reading this absorbing narrative. After almost four decades, the solutions to the epic scientific and philosophical problems posed over this meal in C. P. Snow’s old rooms at Christ’s College remains tantalizingly just out of reach, making this adventure into scientific speculation as valid today as it was in 1949.

    This work demonstrates Popper's importance across the whole range of philosophy and provides an introduction to the main themes of philosophy itself.

    It discusses new results, along with applications of probability theory to a variety of problems. The book contains many exercises and is suitable for use as a textbook on graduate-level courses involving data analysis. Aimed at readers already familiar with applied mathematics at an advanced undergraduate level or higher, it is of interest to scientists concerned with inference from incomplete information.

    The "Theory of Everything" that appears to be emerging includes everything but us: the feelings, meanings, consciousness, and purposes that make us (and many of our animal cousins) what we are. These most immediate and incontrovertible phenomena are left unexplained by the natural sciences because they lack the physical properties—such as mass, momentum, charge, and location—that are assumed to be necessary for something to have physical consequences in the world. This is an unacceptable omission. We need a "theory of everything" that does not leave it absurd that we exist.Incomplete Nature begins by accepting what other theories try to deny: that, although mental contents do indeed lack these material-energetic properties, they are still entirely products of physical processes and have an unprecedented kind of causal power that is unlike anything that physics and chemistry alone have so far explained. Paradoxically, it is the intrinsic incompleteness of these semiotic and teleological phenomena that is the source of their unique form of physical influence in the world. Incomplete Nature meticulously traces the emergence of this special causal capacity from simple thermodynamics to self-organizing dynamics to living and mental dynamics, and it demonstrates how specific absences (or constraints) play the critical causal role in the organization of physical processes that generate these properties.The book's radically challenging conclusion is that we are made of these specific absenses—such stuff as dreams are made on—and that what is not immediately present can be as physically potent as that which is. It offers a figure/background shift that shows how even meanings and values can be understood as legitimate components of the physical world.

    But what will this future look like? In 2062, world-leading researcher Toby Walsh considers the impact AI will have on work, war, economics, politics, everyday life and even death. Will automation take away most jobs? Will robots become conscious and take over? Will we become immortal machines ourselves, uploading our brains to the cloud? How will politics adjust to the post-truth, post-privacy digitised world? When we have succeeded in building intelligent machines, how will life on this planet unfold?Based on a deep understanding of technology, 2062 describes the choices we need to make today to ensure that the future remains bright.‘Clarity and sanity in a world full of fog and uncertainty – a timely book about the race to remain human.’—RICHARD WATSON, author of Digital Vs.

    These theories are not only untrue, it is not even science. It is fairy-tale physics: fantastical, bizarre and often outrageous, perhaps even confidence-trickery.This book provides a much-needed antidote. Informed, comprehensive, and balanced, it offers lay readers the latest ideas about the nature of physical reality while clearly distinguishing between fact and fantasy. With its engaging portraits of many central figures of modern physics, including Paul Davies, John Barrow, Brian Greene, Stephen Hawking, and Leonard Susskind, it promises to be essential reading for all readers interested in what we know and don't know about the nature of the universe and reality itself.

    Along the way, he offers simple and engaging science lessons, proving that you don't have to be a scientist to spot the fraudulent science that swirlsaround us. While remaining highly humorous, this hard-hitting account also tallies the cost: the billions spent on worthless therapies, the tax dollars squandered on government projects that are doomed to fail, the investors bilked by schemes that violate the most fundamental laws of nature. But thegreatest cost is human: fear of imaginary dangers, reliance on magical cures, and above all, a mistaken view of how the world works. To expose the forces that sustain voodoo science, Park examines the role of the media, the courts, bureaucrats and politicians, as well as the scientific community. Scientists argue that the cure is to raise general scientific literacy. But what exactly should a scientifically literate societyknow? Park argues that the public does not need a specific knowledge of science so much as a scientific world view--an understanding that we live in an orderly universe governed by natural laws that cannot be circumvented.

    Einstein considered Bergson's theory of time to be a soft, psychological notion, irreconcilable with the quantitative realities of physics. Bergson, who gained fame as a philosopher by arguing that time should not be understood exclusively through the lens of science, criticized Einstein's theory of time for being a metaphysics grafted on to science, one that ignored the intuitive aspects of time. The Physicist and the Philosopher tells the remarkable story of how this explosive debate transformed our understanding of time and drove a rift between science and the humanities that persists today.Jimena Canales introduces readers to the revolutionary ideas of Einstein and Bergson, describes how they dramatically collided in Paris, and traces how this clash of worldviews reverberated across the twentieth century. She shows how it provoked responses from figures such as Bertrand Russell and Martin Heidegger, and carried repercussions for American pragmatism, logical positivism, phenomenology, and quantum mechanics. Canales explains how the new technologies of the period--such as wristwatches, radio, and film--helped to shape people's conceptions of time and further polarized the public debate. She also discusses how Bergson and Einstein, toward the end of their lives, each reflected on his rival's legacy--Bergson during the Nazi occupation of Paris and Einstein in the context of the first hydrogen bomb explosion.The Physicist and the Philosopher reveals how scientific truth was placed on trial in a divided century marked by a new sense of time.Jimena Canales holds the Thomas M. Siebel Chair in the History of Science at the University of Illinois, Urbana-Champaign, and was previously associate professor of the history of science at Harvard University. She is the author of A Tenth of a Second: A History.Review:"In illuminating a historic 1922 debate between Albert Einstein and Henri Bergson about the nature of time, Canales marks a turning point in the power of philosophy to influence science."--Publishers Weekly"Sparks—both incendiary and illuminating—fly from the collision of two giants!"--Booklist, starred review"This fascinating, scholarly, readable look at physics and epistemology will interest readers of science, history, philosophy, and biography."--Library Journal, starred review"Whether or not you agree, this humane and melancholy account of how two talents misunderstood each other will linger in the mind."--New Scientist"[Canales] weaves a tale around Europe and to America. . . . [Her] subject raises important core philosophical issues, like the scope of philosophy itself."--Michael Ruse, The Chronicle of Higher Education"This fascinating book traces a debate about the nature of time. . . . Canales has done a masterful job of research and explication. Her account of the debate is lively, the background of it is interesting, and the debate’s ramifications as filtered through other minds are downright exciting. Anyone interested in physics or philosophy will have a field day with this book."--Kelly Cherry, The Smart Set"Canales does sterling work investigating these engagements . . . [A] stimulating book."--Graham Farmelo, Nature Endorsement: "The Physicist and the Philosopher explores the nature of time, the meaning of relativity, and the place of philosophical thought in a scientific age. Canales aims to reposition Einstein's work in a field of disputation and give Bergson back the significance he had in his contemporaries' minds."--Cathryn Carson, University of California, Berkeley

    Writing with his characteristic combination of passion and elegant simplicity, he explores the value of truth and finds it to be both less and more than we might imagine.Modern culture exhibits two attitudes toward truth: suspicion of being deceived (no one wants to be fooled) and skepticism that objective truth exists at all (no one wants to be naive). This tension between a demand for truthfulness and the doubt that there is any truth to be found is not an abstract paradox. It has political consequences and signals a danger that our intellectual activities, particularly in the humanities, may tear themselves to pieces.Williams's approach, in the tradition of Nietzsche's genealogy, blends philosophy, history, and a fictional account of how the human concern with truth might have arisen. Without denying that we should worry about the contingency of much that we take for granted, he defends truth as an intellectual objective and a cultural value. He identifies two basic virtues of truth, Accuracy and Sincerity, the first of which aims at finding out the truth and the second at telling it. He describes different psychological and social forms that these virtues have taken and asks what ideas can make best sense of them today. Truth and Truthfulness presents a powerful challenge to the fashionable belief that truth has no value, but equally to the traditional faith that its value guarantees itself. Bernard Williams shows us that when we lose a sense of the value of truth, we lose a lot both politically and personally, and may well lose everything.

    The first is the astonishing achievement of the Human Genome Project, which, it was anticipated, would identify the genetic basis of those characteristics that distinguish humans from their primate cousins. The second is the phenomenal advance in brain imaging that now permits neuroscientists to observe the brain 'in action' and thus account for the remarkable properties of the human mind.But that is not how it has turned out. It is simply not possible to get from the monotonous sequence of genes along the Double Helix to the near infinite diversity of the living world, nor to translate the electrical firing of the brain into the creativity of the human mind. This is not a matter of not knowing all the facts. Rather, science has inadvertently discovered that its theories are insufficient to conjure the wonder of the human experience from the bare bones of our genes and brains.We stand on the brink of a tectonic shift in our understanding of ourselves that will witness the rediscovery of the central premise of Western philosophy that there is 'more than we can know'. Lucid, compelling and utterly engaging, ‘Why Us?’ offers a convincing and provocative vision of the new science of being human.

    This book gives details of their research and investigations into the use of psychedelic drugs for the study of the human mind, and is also a love story. The second half of the book describes in detail a wealth of phenethlyamines, their physical properties, dosages used, duration of effects observed, and commentary on effects.
