If philosophy has any business in the world, it is the clarification of our thinking and the clearing away of ideas that cloud the mind. In this book, one of the world's preeminent philosophers takes issue with an idea that has found an all-too-prominent place in popular culture and philosophical thought: the idea that while factual claims can be rationally established or refuted, claims about value are wholly subjective, not capable of being rationally argued for or against. Although it is on occasion important and useful to distinguish between factual claims and value judgments, the distinction becomes, Hilary Putnam argues, positively harmful when identified with a dichotomy between the objective and the purely "subjective."

Putnam explores the arguments that led so much of the analytic philosophy of language, metaphysics, and epistemology to become openly hostile to the idea that talk of value and human flourishing can be right or wrong, rational or irrational; and by which, following philosophy, social sciences such as economics have fallen victim to the bankrupt metaphysics of Logical Positivism. Tracing the problem back to Hume's conception of a "matter of fact" as well as to Kant's distinction between "analytic" and "synthetic" judgments, Putnam identifies a path forward in the work of Amartya Sen. Lively, concise, and wise, his book prepares the way for a renewed mutual fruition of philosophy and the social sciences.

In this brief book one of the most distinguished living American philosophers takes up the question of whether ethical judgments can properly be considered objective—a question that has vexed philosophers over the past century. Looking at the efforts of philosophers from the Enlightenment through the twentieth century, Hilary Putnam traces the ways in which ethical problems arise in a historical context.

Putnam’s central concern is ontology—indeed, the very idea of ontology as the division of philosophy concerned with what (ultimately) exists. Reviewing what he deems the disastrous consequences of ontology’s influence on analytic philosophy—in particular, the contortions it imposes upon debates about the objective of ethical judgments—Putnam proposes abandoning the very idea of ontology. He argues persuasively that the attempt to provide an ontological explanation of the objectivity of either mathematics or ethics is, in fact, an attempt to provide justifications that are extraneous to mathematics and ethics—and is thus deeply misguided.

Here, in a new edition, is Nelson Goodman’s provocative philosophical classic—a book that, according to Science, “raised a storm of controversy” when it was first published in 1954, and one that remains on the front lines of philosophical debate.

How is it that we feel confident in generalizing from experience in some ways but not in others? How are generalizations that are warranted to be distinguished from those that are not? Goodman shows that these questions resist formal solution and his demonstration has been taken by nativists like Chomsky and Fodor as proof that neither scientific induction nor ordinary learning can proceed without an a priori, or innate, ordering of hypotheses.

In his new foreword to this edition, Hilary Putnam forcefully rejects these nativist claims. The controversy surrounding these unsolved problems is as relevant to the psychology of cognitive development as it is to the philosophy of science. No serious student of either discipline can afford to misunderstand Goodman’s classic argument.

Hilary Putnam’s ever-evolving philosophical oeuvre has been called “the history of recent philosophy in outline”—an intellectual achievement, nearly seventy years in the making, that has shaped disciplinary fields from epistemology to ethics, metaphysics to the philosophy of physics, the philosophy of mathematics to the philosophy of mind. Naturalism, Realism, and Normativity offers new avenues into the thought of one of the most influential minds in contemporary analytic philosophy.

The essays collected here cover a range of interconnected topics including naturalism, commonsense and scientific realism, ethics, perception, language and linguistics, and skepticism. Aptly illustrating Putnam’s willingness to revisit and revise past arguments, they contain important new insights and freshly illuminate formulations that will be familiar to students of his work: his rejection of the idea that an absolute conception of the world is obtainable; his criticism of a nihilistic view of ethics that claims to be scientifically based; his pathbreaking distinction between sensations and apperceptions; and his use of externalist semantics to invalidate certain forms of skepticism. Above all, Naturalism, Realism, and Normativity reflects Putnam’s thinking on how to articulate a theory of naturalism which acknowledges that normative phenomena form an ineluctable part of human experience, thereby reconciling scientific and humanistic views of the world that have long appeared incompatible.

Hilary Putnam’s unceasing self-criticism has led to the frequent changes of mind he is famous for, but his thinking is also marked by considerable continuity. A simultaneous interest in science and ethics—unusual in the current climate of contention—has long characterized his thought. In Philosophy in an Age of Science, Putnam collects his papers for publication—his first volume in almost two decades.

Mario De Caro and David Macarthur’s introduction identifies central themes to help the reader negotiate between Putnam past and Putnam present: his critique of logical positivism; his enduring aspiration to be realist about rational normativity; his anti-essentialism about a range of central philosophical notions; his reconciliation of the scientific worldview and the humanistic tradition; and his movement from reductive scientific naturalism to liberal naturalism. Putnam returns here to some of his first enthusiasms in philosophy, such as logic, mathematics, and quantum mechanics. The reader is given a glimpse, too, of ideas currently in development on the subject of perception.

Putnam’s work, contributing to a broad range of philosophical inquiry, has been said to represent a “history of recent philosophy in outline.” Here it also delineates a possible future.

Throughout his diverse and highly influential career, Hilary Putnam was famous for changing his mind. As a pragmatist he treated philosophical “positions” as experiments in deliberate living. His aim was not to fix on one position but to attempt to do justice to the depth and complexity of reality. In this new collection, he and Ruth Anna Putnam argue that key elements of the classical pragmatism of William James and John Dewey provide a framework for the most progressive and forward-looking forms of philosophy in contemporary thought. The Putnams present a compelling defense of the radical originality of the philosophical ideas of James and Dewey and their usefulness in confronting the urgent social, political, and moral problems of the twenty-first century.

Pragmatism as a Way of Life brings together almost all of the Putnams’ pragmatist writings—essays they wrote as individuals and as coauthors. The pragmatism they endorse, though respectful of the sciences, is an open experience-based philosophy of our everyday lives that trenchantly criticizes the fact/value dualism running through contemporary culture. Hilary Putnam argues that all facts are dependent on cognitive values, while Ruth Anna Putnam turns the problem around, illuminating the factual basis of moral principles. Together, they offer a shared vision which, in Hilary’s words, “could serve as a manifesto for what the two of us would like philosophy to look like in the twenty-first century and beyond.”

The time has come to reform philosophy, says Hilary Putnam, one of America’s great philosophers. He calls upon philosophers to attend to the gap between the present condition of their subject and the human aspirations that philosophy should and once did claim to represent. Putnam’s goal is to embed philosophy in social life.

The first part of this book is dedicated to metaphysical questions. Putnam rejects the contemporary metaphysics that insists on describing both the mind and the world from a God’s-eye view. In its place he argues for pluralism, for a philosophy that is not a closed systematic method but a human practice connected to real life. Philosophy has a task, to be sure, but it is not to provide an inventory of the basic furniture of the universe or to separate reality in itself from our own projections. Putnam makes it clear that science is not in the business of describing a ready-made world, and philosophy should not be in that business either.

The author moves on to show that the larger human context in which science matters is a world of values animated by ethics and aesthetic judgments. No adequate philosophy should try to explain away ethical facts. The dimension of history is added in the third part of the book. Here Putnam takes up a set of American philosophers, some firmly within and others outside the canon of analytic philosophy, such as William James and C. S. Peirce, and he explores the pragmatist contribution to philosophy from James to Quine and Goodman.

This book connects issues in metaphysics with cultural and literary issues and argues that the collapse of philosophical realism does not entail a fall into the abyss of relativism and postmodern skepticism. It is aimed primarily at philosophers but should appeal to a wide range of humanists and social scientists.

Charles Sanders Peirce (1839–1914) was an American philosopher, physicist, mathematician, and the founder of pragmatism. Despite his importance in the history of philosophy, a unified statement of his thought has been unavailable. With this publication, readers at long last are offered the philosopher’s only known, complete, and coherent account of his own work. Originally delivered as the Cambridge Conferences Lectures of 1898, Reasoning and the Logic of Things is the most accessible and thorough introduction to Peirce’s mature thought to be found within the compass of a single book.

Beginning with an explanation of the nature of philosophy, Peirce proceeds to illustrate his claim that mathematics provides the foundation of our logic and metaphysics. We find here the clearest formulation of an idea present in Peirce’s thought since the 1860s, the distinction between three kinds of reasoning: induction, deduction, and retroduction. Then follows an introduction to Peirce’s chief logical doctrines, as well as his attempts to provide a classification of the sciences, a theory of categories, and a theory of science. In conclusion, turning from “reasoning” to the “logic of things,” Peirce called for an evolutionary cosmology to explain the reality of laws and described the kinds of reasoning he employed in developing this cosmology.

At the urging of his friend William James, Peirce made an uncharacteristic effort in these lectures to present his ideas in terms intelligible to a general audience—those without advanced training in logic and philosophy. The introductory materials by Kenneth Ketner and Hilary Putman add to the volume’s lucidity. Consequently, this book will be a valuable source for readers outside of the circle of Peirce specialists.

Franz Rosenzweig, one of the century’s great Jewish thinkers, wrote his gem of a book in 1921 as a more accessible précis of his famous Star of Redemption. An elegant introduction to Rosenzweig’s “new thinking,” Understanding the Sick and the Healthy was written for a lay audience and takes the form of an ironic narrative about convalescence. With superb simplicity and beauty, it puts forth an important critique of the nineteenth-century German Idealist philosophical tradition and expresses a powerful vision of Jewish religion. Harvard’s Hilary Putnam provides a new introduction to this classic work for a contemporary audience.

“Today, more than three-quarters of a century after it was written, the critique of philosophy in this book is what makes it of such great interest. Critique of philosophy has been a central theme of twentieth-century philosophy, and many philosophers have attacked some of the targets that Rosenzweig attacked in his little book. Yet this early attack by a profound religious thinker is far more powerful and far more interesting than most.”—From the new Introduction by Hilary Putnam

Hilary Putnam has been convinced for some time that the present situation in philosophy calls for revitalization and renewal; in this latest book he shows us what shape he would like that renewal to take. Words and Life offers a sweeping account of the sources of several of the central problems of philosophy, past and present, and of why some of those problems are not going to go away. As the titles of the first four parts in the volume—“The Return of Aristotle,” “The Legacy of Logical Positivism,” “The Inheritance of Pragmatism,” and “Essays after Wittgenstein”—suggest, many of the essays are concerned with tracing the recent, and the not so recent, history of these problems.

The goal is to bring out what is coercive and arbitrary about some of our present ways of posing the problems and what is of continuing interest in certain past approaches to them. Various supposedly timeless philosophical problems appear, on closer inspection, to change with altered historical circumstances, while there turns out to be much of permanent value in Aristotle’s, Peirce’s, Dewey’s, and Reichenbach’s work on some of the problems that continue to exercise us.

A unifying theme of the volume as a whole is that reductionism, scientism, and old-style disenchanted naturalism tend to be obstacles to philosophical progress. The titles of the final three parts of the volume—“Truth and Reference,” “Mind and Language,” and “The Diversity of the Sciences”—indicate that the sweep of the problems considered here comprehends all the fundamental areas of contemporary analytic philosophy. Rich in detail, the book is also grand in scope, allowing us to trace the ongoing intellectual evolution of one of the most significant philosophers of the century.
