Wilson Literary Science Writing Award Harvard's top astronomer lays out his controversial theory that our solar system was recently visited by advanced alien technology from a distant star. "Provocative and thrilling ... Loeb asks us to think big and to expect the unexpected."--Alan Lightman, New York Times bestselling author of Einstein's Dreams and Searching for Stars on an Island in Maine In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard's top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization. In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his controversial theory and its profound implications: for science, for religion, and for the future of our species and our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars--and to think critically about what's out there, no matter how strange it seems.

This book is intended for those who wish to assume the responsibility of becoming the new intellectuals. It contains the main philosophical passages from my novels and presents the outline of a new philosophical system.The full system is implicit in these excerpts (particularly in Galt’s speech), but its fundamentals are indicated only in the widest terms and require a detailed, systematic presentation in a philosophical treatise. I am working on such a treatise at present; it will deal predominantly with the issue which is barely touched upon in Galt’s speech: epistemology, and will present a new theory of the nature, source and validation of concepts. This work will require several years; until then, I offer the present book as a lead or a summary for those who wish to acquire an integrated view of existence. They may regard it as a basic outline; it will give them the guidance they need, but only if they think through and understand the exact meaning and the full implications of these excerpts.-- from Preface

2017 Reprint of 1931 Edition. Full facsimile of the original edition, not reproduced with Optical Recognition software. Widely regarded as the principal founder of phenomenology, one of the most important movements in twentieth century philosophy, Edmund Husserl's Ideas is one of his most important works and a classic of twentieth century thought. Husserl's early thought conceived of phenomenology - the general study of what appears to conscious experience - in a relatively narrow way, mainly in relation to problems in logic and the theory of knowledge. The publication of Ideas in 1913 witnessed a significant and controversial widening of Husserl's thought, changing the course of phenomenology decisively. Husserl argued that phenomenology was the study of the very nature of what it is to think, "the science of the essence of consciousness" itself. Husserl's arguments ignited a heated debate regarding the nature of consciousness and experience that has endured throughout the twentieth and continues in the present day. No understanding of twentieth century philosophy is complete without some understanding of Husserl, and his work influenced some of the great philosophers of the twentieth century, such as Martin Heidegger and Jean-Paul Sartre.

Why do 70 percent of Americans believe in angels, while others are convinced that they were abducted by aliens? What makes people believe in improbable things when all the evidence points to the contrary? And don't almost all of us, at some time or another, engage in magical thinking? In Six Impossible Things Before Breakfast, evolutionary biologist Lewis Wolpert delves into the important and timely debate over the nature of belief, looking at its psychological foundations to discover just what evolutionary purpose it could serve. Wolpert takes us through all that science can tell us about the beliefs we feel are instinctive. He deftly explores different types of belief those of children, of the religious, and of those suffering from psychiatric disorders and he asks whether it is possible to live without belief, or whether it is a necessary component of a functioning society."

In this collection of essays, Bromberger explores the centrality of questions and predicaments they create in scientific research. He discusses the nature of explanation, theory, and the foundations of linguistics.

"Jason Stanley presents a startling and provocative claim about knowledge: that whether or not someone knows a proposition at a given time is in part determined by his or her practical interests. Whether a true belief is knowledge is not merely a matter of supporting beliefs or reliability; in the case of knowledge, practical rationality and theoretical rationality are intertwined. Stanley defends this thesis against alternative accounts of the phenomena that motivate it, such as the claim that knowledge attributions are linguistically context-sensitive (contextualism about knowledge attributions), and the claim that the truth of a knowledge claim is somehow relative to the person making the claim (relativism about knowledge)."--BOOK JACKET.

"This is the complete philosophical correspondence between two of the leading analytic philosophers of the late twentieth century, David Armstrong and David Lewis. Ranging from 1968 until Lewis' untimely death in 2001, this volume is an extraordinary philosophical repository of the highest order. It contains the backstory to some of the most important recent works of analytic metaphysics as well as documenting the formation of a deep philosophical friendship"--

" Time Maps extends beyond all of the old clichés about linear, circular, and spiral patterns of historical process and provides us with models of the actual legends used to map history. It is a brilliant and elegant exercise in model building that provides new insights into some of the old questions about philosophy of history, historical narrative, and what is called straight history."-Hayden White, University of California, Santa Cruz Who were the first people to inhabit North America? Does the West Bank belong to the Arabs or the Jews? Why are racists so obsessed with origins? Is a seventh cousin still a cousin? Why do some societies name their children after dead ancestors? As Eviatar Zerubavel demonstrates in Time Maps , we cannot answer burning questions such as these without a deeper understanding of how we envision the past. In a pioneering attempt to map the structure of our collective memory, Zerubavel considers the cognitive patterns we use to organize the past in our minds and the mental strategies that help us string together unrelated events into coherent and meaningful narratives, as well as the social grammar of battles over conflicting interpretations of history. Drawing on fascinating examples that range from Hiroshima to the Holocaust, from Columbus to Lucy, and from ancient Egypt to the former Yugoslavia, Zerubavel shows how we construct historical origins; how we tie discontinuous events together into stories; how we link families and entire nations through genealogies; and how we separate distinct historical periods from one another through watersheds, such as the invention of fire or the fall of the Berlin Wall. Most people think the Roman Empire ended in 476, even though it lasted another 977 years in Byzantium. Challenging such conventional wisdom, Time Maps will be must reading for anyone interested in how the history of our world takes shape.

Philosophers have not taken the evolution of human beings seriously enough. If they did, argues Peter Munz, many long standing philosophical problems would be resolved. One of philosophical concequences of biology is that all the knowledge produced in evolution is a priori , i.e., established hypothetically by chance mutation and selective retention, not by observation and intelligent induction. For organisms as embodied theories, selection is natural and for theories as disembodied organisms, it is artificial. Following Popper, the growth of knowledge is seen to be continuous from the amoeba to Einstein'. Philosophical Darwinism throws a whole new light on many contemporary debates. It has damaging implications for cognitive science and artificial intelligence, and questions attempts from within biology to reduce mental events to neural processes. More importantly, it provides a rational postmodern alternative to what the author argues are the unreasonable postmodern fashions of Kuhn, Lyotard and Rorty.

Professor C. G. Hempel (known to a host of admirers and friends as 'Peter' Hempel) is one of the most esteemed and best loved philosophers in the If an Empiricist Saint were not somewhat of a Meinongian Impos world. sible Object, one might describe Peter Hempel as an Empiricist Saint. In deed, he is as admired for his brilliance, intellectual flexibility, and crea tivity as he is for his warmth, kindness, and integrity, and does not the presence of so many wonderful qualities in one human being assume the dimensions of an impossibility? But Peter Hempel is not only possible but actual! One of us (Hilary Putnam) remembers vividly the occasion on which he first witnessed Hempel 'in action'. It was 1950, and Quine had begun to attack the analytic/synthetic distinction (a distinction which Carnap and Reichenbach had made a cornerstone, if not the keystone, of Logical Em piricist philosophy). Hempel, who is as quick to accept any idea that seems to contain real substance and insight as he is to demolish ideas that are empty or confused, was one of the first leading philosophers outside of Quine's immediate circle to join Quine in his attack. Hempel had come to Los Angeles (where Reichenbach taught) on a visit, and a small group consisting of Reichenbach and a few of his graduate students were gath ered together in Reichenbach's home to hear Hempel defend the new posi tion.

This volume presents, for the first time in English, Husserl’s seminal 1923/24 lecture course First Philosophy ( Erste Philosophie ) together with a selection of material from the famous research manuscripts of the same time period. The lecture course is divided into two systematic, yet interrelated parts (“Critical History of Ideas” and “Theory of the Phenomenological Reduction”). It has long been recognized by scholars as among the most important of the many lecture courses he taught in his career. Indeed it was deemed as crucially important by Husserl himself, who composed it with a view toward eventual publication. It is unsurprising, then, that First Philosophy is the only lecture course that is consistently counted among his major works. In addition to furnishing valuable insights into Husserl’s understanding of the history of philosophy, First Philosophy is his most sustained treatment of the phenomenological reduction,the central concept of his philosophical methodology. The selection of supplemental texts expands on the topics treated in the lectures, but also add other themes from Husserl’s vast oeuvre. The manuscript material is especially worthwhile, because in it, Husserl offers candid self-criticisms of his publicly enunciated words, and also makes forays into areas of his philosophy that he was loath to publicize, lest his words be misunderstood. As Husserl’s position as a key contributor to contemporary thought has, with the passage of time, become increasingly clear, the demand for access to his writings in English has steadily grown. This translation strives to meet this demand by providing English-speaking readers access to this central Husserlian text. It will be of interest to scholars of Husserl’s work, non-specialists, and students of phenomenology.

In this incisive new book one of Britain's most eminent philosophers explores the often overlooked tension between voluntariness and involuntariness in human cognition. He seeks to counter the widespread tendency for analytic epistemology to be dominated by the concept of belief. Is scientific knowledge properly conceived as being embodied, at its best, in a passive feeling of belief or in an active policy of acceptance? Should a jury's verdict declare what its members involuntarily believe or what they voluntarily accept? And should statements and assertions be presumed to express what their authors believe or what they accept? Does such a distinction between belief and acceptance help to resolve the paradoxes of self-deception and akrasia? Must people be taken to believe everything entailed by what they believe, or merely to accept everything entailed by what they accept? Through a systematic examination of these problems, the author sheds new light on issues of crucial importance in contemporary epistemology, philosophy of mind, and cognitive science.

Wittgenstein's later writings generate a great deal of controversy and debate, as do the implications of his ideas for such topics as consciousness, knowledge, language and the arts. Oswald Hanfling addresses a widespeard tendency to ascribe to Wittgenstein views that go beyond those he actually held. Separate chapters deal with important topics such as the private language argument, rule-following, the problem of other minds, and the ascription of scepticism to Wittgenstein. Describing Wittgenstein as a 'humanist' thinker, he contrasts his views on language, art humanity and philosophy itself with those of scientifically minded philosophers. He argues that 'the human form of life' calls for a kind of understanding that cfannot be achieved by the methods of emirical science; that consiousness, for example, cannot properly be regarded as a property of the bran; and that the resulting 'problem of consoiusness is an illusion. Wittgenstein and the Human Form of Life is essential reading for anyone interested in Wittgenstein's approach to what it means to be human. It will be invaluable to all Wittgenstein scholars, and all who are interested in the philosophy of mind, language and aesthetics.

In this important and broad-ranging book, Israel Scheffler explores the various ways in which the mind functions symbolically. This involves considering not only the worlds of the sciences and the arts, but also such activities as religious ritual and child's play. The book offers an integrated treatment of ambiguity and metaphor, analyses of play and ritual, and an extended discussion of the relations between scientific symbol systems and reality. What emerges is a picture of the basic symbol-forming character of the mind.

A reprint of the popular 1969, Prentice-Hall edition, the principal innovation of this philosophical introduction to value theory is its focus upon values as they are dealt with in everyday life situations, and have sometimes been studied by sociologists and social psychologists, rather than upon value as has been standard in the philosophical tradition. The treatment of values is developed in the light of relevant work in the social sciences, particularly economics. The result is a book suitable as a textbook for upper-class and graduate courses in the theory of values and as supplementary material for both courses in normative ethics and foundations-oriented courses in economic theory.

With this first of eight volumes, the eminent economist Fritz Machlup launches his monumental inquiry into the production of knowledge as an economic activity. Volume I presents the conceptual framework for this inquiry and falls into three parts: Types of Knowledge, Qualities of Knowledge, and Knowledge as a Product. Originally published in 1981. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
