This final volume of "The Works of William James" provides a full record of James's teaching career at Harvard from 1872 to 1907. It includes extensive working notes for lectures in more than twenty courses. Some of the notes contain summary statements of views of James's that have never been published before, such as his treatment of the question of proof in ethics, in the only course he ever taught in that subject; others reflect contemporary controversies in philosophy, notably the famous debate on Idealism and the nature of the Absolute; still others illuminate early stages of James's thinking on crucial problems in what was to become his philosophy of radical empiricism. Often the notes yield information about his sources that is not to be found in the published writings. Because James's teaching was so closely involved with the development of his thought, this unpublished material adds a new dimension to our understanding of his philosophy.

James's public lectures gained him world renown, and most of them were subsequently published. There are, however, several sets of notes for and drafts of important lectures that he never wrote out for publication; these are included in the present volume. Among them are his two series of lectures in 1878 on the physiology of the brain and its relation to the mind; the Lowell Lectures of 1896 on exceptional mental states; and the lectures of 1902 on intellect and feeling in religions, which were designed to supplement "Varieties of Religious Experience" and were intended to be his last word on the psychology of religion.

"It is absolutely the only philosophy with no humbug in it," an exhilarated William James wrote to a friend early in 1907. And later that year, after finishing the proofs of his "little book," he wrote to his brother Henry: "I shouldn't be surprised if ten years hence it should be rated as 'epoch-making, ' for of the definitive triumph of that general way of thinking I can entertain no doubt whatever--I believe it to be something quite like the protestant reformation."

Both the acclaim and outcry that greeted "Pragmatism: A New Name for Some Old Ways of Thinking" helped to affirm James's conviction. For it was in "Pragmatism" that he confronted older philosophic methods with the "pragmatic" method, demanding that ideas be tested by their relation to life and their effects in experience. James's reasoning and conclusions in "Pragmatism" have exerted a profound influence on philosophy in this century, and the book remains a landmark.

"The Will to Believe" addresses several of the most important and perplexing problems of philosophy. In ten lucid essays James deals with such subjects as causality and free will, the definition of the good life and the Good itself, the importance of the individual in society, and the intellectual claims of scientific method. Linking all these essays, most of which were delivered as lectures to popular audiences, is James's deep belief that philosophy does not operate in a vacuum but is influenced by our passional and volitional natures.

As Edward H. Madden points out in his substantial introduction, these essays, written over a span of seventeen years, represent not so much a fixed system of ideas as a patient searching, an organic development of James's thought in response to his own criticism and that of others.

This is the sixth volume to be published in "The Works of William James," an authoritative edition sponsored by the American Council of Learned Societies.

"Essays in Philosophy" brings together twenty-one essays, reviews, and occasional pieces published by James between 1876 and 1910. They range in subject from a concern with the teaching of philosophy and appraisals of philosophers to analyses of important problems.

Several of the essays, like "The Sentiment of Rationality" and "The Knowing of Things Together," are of particular significance in the development of the views of James's later works. All of them, as John McDermott says in his Introduction, are in a style that is "engaging and personal...witty, acerbic, compassionate, and polemical." Whether he is writing an article for the "Nation" of a definition of "Experience" for Baldwin's "Dictionary" or "The Mad Absolute" for the "Journal of Philosophy," James is always unmistakably himself, and always readable.

In "Pragmatism" James attacked the transcendental, rationalist tradition in philosophy and tried to clear the ground for the doctrine he called radical empiricism. The hook caused an uproar; it was greeted with praise, hostility, ridicule. Determined to clarify the pragmatic conception of truth, James collected nine essays he had written on this subject before he wrote "Pragmatism" and six written later in response to criticisms of that volume by Bertrand Russell and others. He published the collection under the title "The Meaning of Truth" in 1909, the year before his death.

"The Meaning of Truth" shows James at his best--clear and readable as always, and full of verve and good humor. Intent upon making difficult ideas clear, he is also forceful in his effort to make them prevail.

In May 1908 William James, a gifted and popular lecturer, delivered a series of eight Hibbert lectures at Manchester College, Oxford, on "The Present Situation in Philosophy." These were published a year later as "A Pluralistic Universe,"

During the preceding decade James, as he struggled with deep conflicts within his own philosophic development, had become increasingly preoccupied with epistemological and metaphysical issues. He saw serious inadequacies in the forms of absolute and monistic idealism dominant in England and the United States, and he used the lectures to attack the specific form that "vicious intellectualism" had taken.

In "A Pluralistic Universe" James captures a new philosophic vision, at once intimate and realistic. He shares with his readers a view of the universe that is fresh, active, and novel. The message conveyed is as relevant today as it was in his time.

Supervised by a team of scholars, each a specialist in his field, "The Works of William James" fills the long-standing need for an authoritative, standard edition of the philosopher's works. The General Editor and supervisor of the project is Frederick Burkhardt. Mr. Burkhardt, formerly a professor of philosophy and then a college president, is President Emeritus of the American Council of Learned Societies. The Textual Editor, Fredson Bowers, Linden Kent Professor of English at the University of Virginia, is in charge of the establishment of the text and its production according to standards of the Center for Editions of American Authors. Gold Medalist of the Bibliographical Society, Fellow of the American Academy of Arts and Sciences, and Corresponding Fellow of The British Academy, Mr.Bowers is the author of two books on the theory and practice of textual criticism and editor of several multivolume critical editions. Ignas K. Skrupskelis, the Associate Editor, contributes the substantive notes. He is Associate Professor of Philosophy at the University of South Carolina and has conducted extensive research in the James collection.

A pioneer in early studies of the human mind and founder of that peculiarly American philosophy called Pragmatism, William James remains America's most widely read philosopher. Generations of students have been drawn to his lucid presentations of philosophical problems. His works, now being made available for the first time in a definitive edition, have a permanent place in American letters and a continuing influence in philosophy and psychology.

The essays gathered in the posthumously published "Essays in Radical Empiricism" formulate ideas that had brewed in James's mind for thirty years as he sought a way out of the philosophical dilemmas generated by the new psychology of the late nineteenth century. They constitute the explanatory core of his doctrine of radical empiricism, a doctrine that charts his course between the absolute idealism he could not accept and, at the other extreme, the law of associationism, which reduces knowledge to sheer contiguity of ideas. In his introduction John J. McDermott describes the historical background and the genesis of James's theory and considers the objections raised by its opponents.
