It features essays on life and consciousness, soul and body, mind and brain, and on dreams, memory and the phenomenon of false recognition; the insights Bergson develops in them remain highly pertinent to contemporary work in the philosophy of mind.

    As we enter the year 2000, zero is once again making its presence felt. Nothing itself, it makes possible a myriad of calculations. Indeed, without zero mathematicsas we know it would not exist. And without mathematics our understanding of the universe would be vastly impoverished. But where did this nothing, this hollow circle, come from? Who created it? And what, exactly, does it mean? Robert Kaplan's The Nothing That Is: A Natural History of Zero begins as a mystery story, taking us back to Sumerian times, and then to Greece and India, piecing together the way the idea of a symbol for nothing evolved. Kaplan shows us just how handicapped our ancestors were in trying to figurelarge sums without the aid of the zero. (Try multiplying CLXIV by XXIV). Remarkably, even the Greeks, mathematically brilliant as they were, didn't have a zero--or did they? We follow the trail to the East where, a millennium or two ago, Indian mathematicians took another crucial step. By treatingzero for the first time like any other number, instead of a unique symbol, they allowed huge new leaps forward in computation, and also in our understanding of how mathematics itself works. In the Middle Ages, this mathematical knowledge swept across western Europe via Arab traders. At first it was called dangerous Saracen magic and considered the Devil's work, but it wasn't long before merchants and bankers saw how handy this magic was, and used it to develop tools likedouble-entry bookkeeping. Zero quickly became an essential part of increasingly sophisticated equations, and with the invention of calculus, one could say it was a linchpin of the scientific revolution. And now even deeper layers of this thing that is nothing are coming to light: our computers speakonly in zeros and ones, and modern mathematics shows that zero alone can be made to generate everything.Robert Kaplan serves up all this history with immense zest and humor; his writing is full of anecdotes and asides, and quotations from Shakespeare to Wallace Stevens extend the book's context far beyond the scope of scientific specialists. For Kaplan, the history of zero is a lens for looking notonly into the evolution of mathematics but into very nature of human thought. He points out how the history of mathematics is a process of recursive abstraction: how once a symbol is created to represent an idea, that symbol itself gives rise to new operations that in turn lead to new ideas. Thebeauty of mathematics is that even though we invent it, we seem to be discovering something that already exists.The joy of that discovery shines from Kaplan's pages, as he ranges from Archimedes to Einstein, making fascinating connections between mathematical insights from every age and culture. A tour de force of science history, The Nothing That Is takes us through the hollow circle that leads to infinity.

    Daniel Dennett, whose previous books include "Brainstorms "and (with Douglas Hofstadter) "The Mind's I, " tackles the free will problem in a highly original and witty manner, drawing on the theories and concepts of several fields usually ignored by philosophers; not just physics and evolutionary biology, but engineering, automata theory, and artificial intelligence.In "Elbow Room," Dennett shows how the classical formulations of the problem in philosophy depend on misuses of imagination, and he disentangles the philosophical problems of real interest from the "family of anxieties' they get enmeshed in - imaginary agents, bogeymen, and dire prospects that seem to threaten our freedom. Putting sociobiology in its rightful place, he concludes that we can have free will and science too. "Elbow Room" begins by showing how we can be "moved by reasons" without being exempt from physical causation. It goes on to analyze concepts of control and self-control-concepts often skimped by philosophers but which are central to the questions of free will and determinism. A chapter on "self-made selves" discusses the idea of self or agent to see how it can be kept from disappearing under the onslaught of science. Dennett then sees what can be made of the notion of acting under the idea of freedomdoes the elbow room we think we have really exist? What is an opportunity, and how can anything in our futures be "up to us"? He investigates the meaning of "can" and "could have done otherwise," and asks why we want free will in the first place.We are wise, Dennett notes, to want free will, but that in itself raises a host of questions about responsibility. In a final chapter, he takes up the problem of how anyone can ever be guilty, and what the rationale is for holding people responsible and even, on occasion, punishing them."Elbow Room "is an expanded version of the John Locke Lectures which Dennett gave at Oxford University in 1983.

    Heath's translation of the thirteen books of Euclid's Elements. In keeping with Green Lion's design commitment, diagrams have been placed on every spread for convenient reference while working through the proofs; running heads on every page indicate both Euclid's book number and proposition numbers for that page; and adequate space for notes is allowed between propositions and around diagrams. The all-new index has built into it a glossary of Euclid's Greek terms.Heath's translation has stood the test of time, and, as one done by a renowned scholar of ancient mathematics, it can be relied upon not to have inadvertantly introduced modern concepts or nomenclature. We have excised the voluminous historical and scholarly commentary that swells the Dover edition to three volumes and impedes classroom use of the original text. The single volume is not only more convenient, but less expensive as well.

    More than two centuries after Euler's death, it is still regarded as a conceptual diamond of unsurpassed beauty. Called Euler's identity or God's equation, it includes just five numbers but represents an astonishing revelation of hidden connections. It ties together everything from basic arithmetic to compound interest, the circumference of a circle, trigonometry, calculus, and even infinity. In David Stipp's hands, Euler's identity formula becomes a contemplative stroll through the glories of mathematics. The result is an ode to this magical field.

    More accessible than his other books, Introduction to Logic lays the foundation for his writings with a clear discussion of each of his philosophical pursuits. For more advanced Kantian scholars, this book can bring to light some of the enduring issues in Kant's repertoire, and for the beginner, it can open up the philosophical ideas of one of most influential thinkers on modern philosophy. This edition comprises two parts, including the first Introduction to Logic and the second an essay titled The False Subtlety of the Four Syllogistic Figures, in which Kant analyzes Aristotelian logic. Immanuel Kant was a Prussian philosopher, physicist, and mathematician whose contributions to the study of logic, epistemology, metaphysics, aesthetics, and moral reasoning have had a lasting influence on philosophical scholarship. Born in K�nigsberg, East Prussia in 1724 to a modest family, Kant was raised Pietist, and initially went to the University of K�nigsberg to study theology. He later abandoned theology for mathematics and physics after becoming interested in the work of Sir Isaac Newton. He was appointed chair of logic and metaphysics at the University of K�nigsberg and, at the height of the Enlightenment, began publishing his most famous philosophical texts, including his most important work, Foundations of the Metaphysics of Morals. Kant has had a tremendous impact on modern philosophy, influencing scholars throughout history, including Karl Marx and G. W. F. Hegel, and he continues to be read and studied today.

    

    Ryle's linguistic analysis remaps the conceptual geography of mind, not so much solving traditional philosophical problems as dissolving them into the mere consequences of misguided language. His plain language and esstentially simple purpose place him in the traditioin of Locke, Berkeley, Mill, and Russell.

    H. Hardy was one of this century's finest mathematical thinkers, renowned among his contemporaries as a 'real mathematician ... the purest of the pure'. He was also, as C. P. Snow recounts in his Foreword, 'unorthodox, eccentric, radical, ready to talk about anything'. This 'apology', written in 1940 as his mathematical powers were declining, offers a brilliant and engaging account of mathematics as very much more than a science; when it was first published, Graham Greene hailed it alongside Henry James's notebooks as 'the best account of what it was like to be a creative artist'. C. P. Snow's Foreword gives sympathetic and witty insights into Hardy's life, with its rich store of anecdotes concerning his collaboration with the brilliant Indian mathematician Ramanujan, his aphorisms and idiosyncrasies, and his passion for cricket. This is a unique account of the fascination of mathematics and of one of its most compelling exponents in modern times.

    This work represents, along with Existence and Existents (1947), the first formulation of Emmanuel Levinas's own philosophy, later more fully developed in Totality and Infinity (1961) and Otherwise than Being, or Beyond Essence (1974).Beginning with an analysis of existence without existents, Time and the Other then describes the origination of the subject, and moves through its encounter with another person. It is in this encounter rather than in the world that Levinas discovers time in its full sense. The progression of Levinas's phenomenology moves towards alterity, not toward totality. Levinas connects the alterity of the Other with temporality; the Other who is encountered is not contemporary, not met "at the same time." The time of the Other disrupts or interrupts the self's own temporality.This is essential reading for all those interested in Levinas, and an excellent starting point for understanding the nature of Levinas's philosophical project and thought.

    Petr Beckmann holds up this mirror, giving the background of the times when pi made progress -- and also when it did not, because science was being stifled by militarism or religious fanaticism.

    In recent years, however, the concept of information has gained importance. Why? In this book, eminent scientists, philosophers and theologians chart various aspects of information, from quantum information to biological and digital information, in order to understand how nature works. Beginning with a historical treatment of the topic, the book also examines physical and biological approaches to information, and its philosophical, theological and ethical implications.

    While many of the mathematicians and software engineers on Wall Street failed when their abstractions turned ugly in practice, a special breed of physicists has a much deeper history of revolutionizing finance. Taking us from fin-de-siècle Paris to Rat Pack-era Las Vegas, from wartime government labs to Yippie communes on the Pacific coast, Weatherall shows how physicists successfully brought their science to bear on some of the thorniest problems in economics, from options pricing to bubbles.The crisis was partly a failure of mathematical modeling. But even more, it was a failure of some very sophisticated financial institutions to think like physicists. Models—whether in science or finance—have limitations; they break down under certain conditions. And in 2008, sophisticated models fell into the hands of people who didn’t understand their purpose, and didn’t care. It was a catastrophic misuse of science.The solution, however, is not to give up on models; it's to make them better. Weatherall reveals the people and ideas on the cusp of a new era in finance. We see a geophysicist use a model designed for earthquakes to predict a massive stock market crash. We discover a physicist-run hedge fund that earned 2,478.6% over the course of the 1990s. And we see how an obscure idea from quantum theory might soon be used to create a far more accurate Consumer Price Index.Both persuasive and accessible, The Physics of Wall Street is riveting history that will change how we think about our economic future.
