His book must be read three times: the first in anger, the second in laughter, the third in respect....The wisdom is expressed with a certain ruthlessness. Scarcely a major historian escapes unscathed. Ten thousand members of the American Historical Association will rush to the index and breathe a little easier to find their names absent.

    Here he explains how our image of the world has changed throughout centuries. Fom Aristotle to Albert Einstein, Michael Faraday to the Higgs boson, he takes us on a wondrous journey to show us that beyond our ever-changing idea of reality is a whole new world that has yet to be discovered.

    The material of this book is indispensable for anyone who wishes to understand the real spiritual roots of Western civilization.

    Part 1, on propositional logic, is the old Introduction, but contains much new material. Part 2 is entirely new, and covers quantification and identity for all the logics in Part 1. The material is unified by the underlying theme of world semantics. All of the topics are explained clearly using devices such as tableau proofs, and their relation to current philosophical issues and debates are discussed. Students with a basic understanding of classical logic will find this book an invaluable introduction to an area that has become of central importance in both logic and philosophy. It will also interest people working in mathematics and computer science who wish to know about the area.

    A timeless introduction to the field and a landmark in symbolic logic, showing that classical logic can be treated algebraically.

    As a student and young researcher in the 1980s, Gelernter hoped to build a program with a dial marked "focus." At maximum "focus," the program would "think" rationally, formally, reasonably. As the dial was turned down and "focus" diminished, its "mind" would start to wander, and as you dialed even lower, this artificial mind would start to free-associate, eventually ignoring the user completely as it cruised off into the mental adventures we know as sleep.While the program was a only a partial success, it laid the foundation for The Tides of Mind, a groundbreaking new exploration of the human psyche that shows us how the very purpose of the mind changes throughout the day. Indeed, as Gelernter explains, when we are at our most alert, when reasoning and creating new memories is our main mental business, the mind is a computer-like machine that keeps emotion on a short leash and attention on our surroundings. As we gradually tire, however, and descend the "mental spectrum," reasoning comes unglued. Memory ranges more freely, the mind wanders, and daydreams grow more insistent. Self-awareness fades, reflection blinks out, and at last we are completely immersed in our own minds.With far-reaching implications, Gelernter’s landmark "Spectrum of Consciousness" finally helps decode some of the most mysterious wonders of the human mind, such as the numinous light of early childhood, why dreams are so often predictive, and why sadism and masochism underpin some of our greatest artistic achievements. It’s a theory that also challenges the very notion of the mind as a machine—and not through empirical studies or "hard science" but by listening to our great poets and novelists, who have proven themselves as humanity's most trusted guides to the subjective mind and inner self.In the great introspective tradition of Wilhelm Wundt and René Descartes, David Gelernter promises to not only revolutionize our understanding of what it means to be human but also to help answer many of our most fundamental questions about the origins of creativity, thought, and consciousness.

    This book examines how science comes to be used as a substitute for religion and points out how badly that role distorts it. Her argument is flawlessly insightful: a punch, compelling, lively indictment of these misuses of science. Both the book and its author are true classics of our time.

    Happiness, he says, is not 'out there' but within, a state of mind that is independent of circumstance: 'If you begin to see that your thoughts are not the real thing – they're just thoughts and as thoughts they can't hurt you – your entire life will begin to change today.'Carlson's step-by-step guide explains:• How your thoughts determine how you feel.• Why thinking about problems only makes them worse.• That thoughts come and go – you are free to choose at any moment which to hold on to and which to let go.• Straightforward methods for conquering depression.• How to dismiss negative thoughts and discover inner contentment.• How to overcome lifelong pessimism and start really living.

    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.

    Perhaps ideas have us. After all, ideas do appear to have a life of their own. And it is they, not us, that benefit most when they are spread. Many biologists have already come to the opinion that our genes are selfish entities, tricking us into helping them to reproduce. Is it the same with our ideas?     Jonnie Hughes, a science writer and documentary filmmaker, investigates the evolution of ideas in order to find out. Adopting the role of a cultural Charles Darwin, Hughes heads off, with his brother in tow, across the Midwest to observe firsthand the natural history of ideas—the patterns of their variation, inheritance, and selection in the cultural landscape. In place of Darwin’s oceanic islands, Hughes visits the “mind islands” of Native American tribes. Instead of finches, Hughes searches for signs of natural selection among the tepees.     With a knack for finding the humor in the quirks of the American cultural landscape, Hughes takes us on a tour from the Mall of America in Minneapolis to what he calls the “maul” of America—Custer’s last stand—stopping at road-sides and discoursing on sandwiches, the shape of cowboy hats, the evolution of barn roofs, the wording of jokes, the wearing of moustaches, and, of course, the telling features from tepees of different tribes. Original, witty, and engaging, On the Origin of Tepees offers a fresh way of understanding both our ideas and ourselves.

    In this treatise, he argues that the core intellectual errors of statism, socialism, protectionism, racism, irrationalism can be found in a revolt against economic logic and its special character. Epistemological Problems of Economics was original published in 1933, a period when the social sciences and economic policy were undergoing upheaval. The classical view of economics as a deductive science, along with the laissez-faire policies implied by that view, were being displaced by positivism and economic planning. Mises set out to put the classical view on a firmer foundation. In so doing, he examines a range of philosophical problems associated with economics. He goes further to delineate the scope of the general science of human action. This treatise, out of print for many years, is now brought back by the Mises Institute in a 3rd edition, with a comprehensive introduction by Jörg Guido Hülsmann, senior fellow of the Mises Institute. He observes that "the great majority of contemporary economists, sociologists, political scientists, and philosophers are either completely unaware of Mises's contributions to the epistemology of the social sciences or think they can safely neglect dealing with them. They are in error. One can ignore a thinker, but the fundamental problems of social analysis remain. There will be no progress in these disciplines before the mainstream has fully absorbed and digested Mises's ideas."
