Vico’s theory of poetic origins greatly influenced Harold Bloom’s theory of poetry, called “the anxiety of influence.” Neither simple acceptance nor rejection, the complex influence is explained at main stages of Bloom’s career. In Bloom’s early writings, Vico’s ideas are virtually ignored. Starting with The Anxiety of Influence, Vico’s influence is acknowledged to be strong but it is repressed; Vico’s ideas are mentioned in only a few brief passages and usually presented through those of other thinkers, or are interpreted to (...) be the same. In subsequent works, Bloom does discuss Vico’s ideas more. Finally, in Bloom’s Western Canon, Vico’s importance seems to be the greatest, since all the literature is categorized according to Vico’s idea of a cycle of three ages, although, once again, his ideas are not analyzed.

The relationship between William James and Ludwig Wittgenstein (1889-1951) has recently been the subject of intense scholarly research. We know for instance that the later Wittgenstein's reflections on the philosophy of psychology found in James a major source of inspiration. Not surprisingly therefore, the pragmatist nature of the philosophy of the later Wittgenstein is increasingly acknowledged, in spite of Wittgenstein’s adamant refusal of being labeled a “pragmatist”. In this brief paper I merely want to piece together some of the (...) available evidence of Wittgenstein’s high regard for William James, not only for his thoughts, but even more so for his character.

In this short paper I try to present William James’s connection with the Argentinian writer Macedonio Fernández (1874-1952), who was in some sense a mentor of Borges and might be considered the missing link between Borges and James.
The year of the centennial of the Argentinean writer Jorge Luis Borges is probably the right time to exhume one of the links that this universal writer had with William James. In 1945, Emece, a publisher from Buenos Aires, printed a Spanish translation of William James’s book Pragmatism, with a foreword by Jorge Luis Borges.
The original 1907 text of James' Pragmatism is accompanied with a series of critical essays from scholars including Moore and Russell. In the introduction Olin evaluates the strength of the criticisms made against James.
William James's theory of emotion is often criticized for placing too much emphasis on bodily feelings and neglecting the cognitive aspects of emotion. This paper suggests that such criticisms are misplaced. Interpreting James's account of emotion in the light of his later philosophical writings, I argue that James does not emphasize bodily feelings at the expense of cognition. Rather, his view is that bodily feelings are part of the structure of intentionality. In reconceptualizing the relationship between cognition and affect, (...) James rejects a number of commonplace assumptions concerning the nature of our cognitive relationship with the world, assumptions that many of his critics take for granted. (shrink)
This book is my new scholarly edition of William James, A Pluralistic Universe. The original text has been recovered, annotations to the text added to identify James' authors and events of interest, there is a new bibliography chiefly based on James' sources, a brief chronology of James' career, and I have added an expository and critical Introduction and a comprehensive analytical index.
As suggested in the subtitle, A New Philosophical Reading, the editor aspires in his Introduction and his notes to “facilitate a deeper understanding and a critical evaluation (...) of this crucial and difficult philosophical work” (p. ix). This was the last important book which James published during his lifetime. With it James aims at a critical evaluation of Hegelian monism and an exploration of the philosophical and theological alternatives. “Our world of some one hundred years on”—the editor says (p. ix)—“is (...) much the better for James’ contribution, and understanding William James on pluralism deeply contributes even now to America’s self-understanding.”.

In 1907 William James was invited to give the Hibbert Lectures at Manchester College, Oxford. Initially he was reluctant to do so since he feared undertaking them would divert him from developing rigorously and systematically some metaphysical ideas of his own that had preoccupied him for some time. In the end, however, he relented and in the spring of 1908 gave the lectures which were subsequently published as A Pluralistic Universe. As it happened, though, in the course of these (...) lectures James presented some of those metaphysical ideas, though in a popular and informal style appropriate to lecturing. Later on he did get down to working out a systematic metaphysics in proper academic style, but the project was cut short by his untimely death in 1910. The incomplete Some Problems of Philosophy, posthumously published in 1911, recapitulates some major themes of A Pluralistic Universe. (shrink)
This new edition of William James’s 1909 classic, A Pluralistic Universe reproduces the original text, only modernizing the spelling. The books has been annotated throughout to clarify James’s points of reference and discussion. There is a new, fuller index, a brief chronology of James’s life, and a new bibliography—chiefly based on James’s own references. The editor, H.G. Callaway, has included a new Introduction which elucidates the legacy of Jamesian pluralism to survey some related questions of contemporary American society. -/- (...) A Pluralistic Universe was the last major book James published during his life time. It is a substantial philosophical work, devoted to a thorough-going criticism of Hegelian monism and Absolutism—and the exploration of philosophical and social-theological alternatives. Our world of some one hundred years on is much the better for James’s contributions; and understanding James’s pluralism deeply contributes even now to America’s self-understanding. At present, we are more certain that American is, and is best, a pluralistic society, than we are of what particular forms our pluralism should take. Keeping an eye out for social interpretations of Jamesian pluralism, this new philosophical reading casts light on our twenty-first century alternatives by reference to prior American experience and developments. -/- .

: William James's "The Will to Believe" has been criticized for offering untenable arguments in support of belief in unvalidated hypotheses. Although James is no longer accused of suggesting we can create belief ex nihilo, critics continue to charge that James's defense of belief in what he called the "religious hypothesis" confuses belief with hypothesis adoption and endorses willful persistence in unvalidated beliefs—not, as he claimed, in pursuit of truth, but merely to avoid the emotional stress of abandoning them. (...) I argue that James's position in "The Will to Believe" can be defended provided we give up thinking of it as ethics of belief and think of it instead as an ethics of self-experimentation. Subjective data (including wants, needs, and desires) are relevant to rational consent to participation in research. (shrink)
William James is remembered as the philosopher of pragmatism, but he was principally the founder of modern scientific psychology. During the period of his most intense scientific involvement James developed a trenchant critique of science. This was not a rejection of science but an attempt to identify limitations of the contemporary conceptualization of science. In particular, James emphasized the failure of science to understand its basis in human emotions. James developed a scientific theory of emotions in which the importance (...) of emotion in cognition and decision-making is central. James’ appreciation of the significance of emotions in science has continuing value. Nevertheless, his characterization of science in terms of its method introduces tensions in his account that an emphasis on the social dimensions of science, which he implicitly acknowledged, tends to resolve.

This book explores Wittgenstein's long engagement with the work of the pragmatist William James. In contrast to previous discussions Russell Goodman argues that James exerted a distinctive and pervasive positive influence on Wittgenstein's thought. For example, the book shows that the two philosophers share commitments to anti-foundationalism, to the description of the concrete details of human experience, to the priority of practice over intellect, and to the importance of religion in understanding human life. Considering in detail what Wittgenstein learnt (...) from his reading of Principles of Psychology and Varieties of Religious Experience the author provides considerable evidence for Wittgenstein's claim that he is saying 'something that sounds like pragmatism'. This provocative account of the convergence in the thinking of two major philosophers usually considered as members of discrete traditions will be eagerly sought by students of Wittgenstein, William James, pragmatism and the history of twentieth-century philosophy.

William James (1842-1910) was both a philosopher and a psychologist, nowadays most closely associated with the pragmatic theory of truth. The essays in this Companion deal with the full range of his thought as well as other issues, including technical philosophical issues, religious speculation, moral philosophy and political controversies of his time. The relationship between James and other philosophers of his time, as well as his brother Henry, are also examined. By placing James in his intellectual landscape the volume (...) will be particularly useful to teachers and students outside philosophy in such areas as religious studies, history of ideas, and American studies. New readers and nonspecialists will find this the most convenient and accessible guide to James currently available. Advanced students and specialists will find a conspectus of recent developments in the interpretation of James. (shrink)
ABSTRACT. May scientists rely on substantive, a priori presuppositions? Quinean naturalists say "no," but Michael Friedman and others claim that such a view cannot be squared with the actual history of science. To make his case, Friedman offers Newton's universal law of gravitation and Einstein's theory of relativity as examples of admired theories that both employ presuppositions (usually of a mathematical nature), presuppositions that do not face empirical evidence directly. In fact, Friedman claims that the use of such presuppositions is (...) a hallmark of "science as we know it." But what should we say about the special sciences, which typically do not rely on the abstruse formalisms one finds in the exact sciences? I identify a type of a priori presupposition that plays an especially striking role in the development of empirical psychology. These are ontological presuppositions about the type of object a given science purports to study. I show how such presuppositions can be both a priori and rational by investigating their role in an early flap over psychology's contested status as a natural science. The flap focused on one of the field's earliest textbooks, William James's Principles of Psychology. The work was attacked precisely for its reliance on a priori presuppositions about what James had called the "mental state," psychology's (alleged) proper object. I argue that the specific presuppositions James packed into his definition of the "mental state" were not directly responsible to empirical evidence, and so in that sense were a priori; but the presuppositions were rational in that they were crafted to help overcome philosophical objections (championed by neo-Hegelians) to the very idea that there can be a genuine science of mind. Thus, my case study gives an example of substantive, a priori presuppositions being put to use—to rational use—in the special sciences. In addition to evaluating James's use of presuppositions, my paper also offers historical reflections on two different strands of pragmatist philosophy of science. One strand, tracing back through Quine to C. S. Peirce, is more naturalistic, eschewing the use of a priori elements in science. The other strand, tracing back through Kuhn and C. I. Lewis to James, is more friendly to such presuppositions, and to that extent bears affinity with the positivist tradition Friedman occupies. (shrink)
This article by John Dewey is an early appreciation of William James, written at the time of James' death. Dewey would write much more on James in later years.
The project method became a famous teaching method when William Heard Kilpatrick published his article ‘Project Method’ in 1918. The key idea in Kilpatrick's project method is to try to explain how pupils learn things when they work in projects toward different common objects. The same idea of pupils learning by work or action in an environment with objects also belongs to John Dewey's problem-solving method. Are Kilpatrick's project method and Dewey's problem-solving method the same thing? The aim of (...) this article is to analyze and prove that Kilpatrick's project method differs radically from Dewey's problem-solving method. (shrink)
: It is part of the conventional wisdom about the James family that the elder Henry James (1811–82) had a large influence on his son, William James (1842–1910), in the direction of religious interests. But William neither adopted his father's spirituality nor did he regard it as a foil to his own secularity. Instead, after first rejecting the elder James's idiosyncratic faith, he became increasingly intrigued with his insights into the natural world, which were in turn shaped by (...) the Swedenborgian philosophy of correspondences and use, which depict worldly facts as vessels of the spirit. The young science student drew upon this approach to nature as a resource for finding the operation of immaterial aspects within the world. The influence of the father emerges in William's emphasis on the will in human psychology, his eagerness to punctuate the striving of "the will to believe" with sessions of comforting conviction, his readiness to find "'piecemeal' supernaturalism" in subliminal psychology, his incorporation of idealism into his radical empiricism, and his openness to psychical experience. Without accepting the particulars of Henry James's faith, William James shared with his father a conviction that providential action in the universe, usually understood as the work of transcendental forces, was embedded within the natural world and within humankind.

William James undertook to steer his way between a rationalistic system that was not empirical enough and an empirical system so materialistic that it could not account for the value commitments on which it rested. In arguing against both the absolutists (gnostics) and the empiricists (agnostics), he defined a position of pluralistic moralism that seemed equally distant from both, leaving himself vulnerable to the criticism that he had rescued morality from scientism only by reducing religion to morals. Such criticism, (...) however, ignores distinctions James made between religion and theology and between monistic theology and dualistic theology. When these distinctions are taken into account, it becomes evident that James can be criticized for reducing religion to morality only from the point of view of either absolute monism or religious humanism and that radical empiricism not only embraces a significant number of nonmoral religious experiences but also leaves open the possibility of belief in the particular historical God of traditional Christianity.

This book offers a new interpretation of William James's ethical and religious thought. Michael Slater shows that James's conception of morality, or what it means to lead a moral and flourishing life, is intimately tied to his conception of religious faith, and argues that James's views on these matters are worthy of our consideration. He offers a reassessment of James's 'will to believe' or 'right to believe' doctrine, his moral theory, and his neglected moral arguments for religious faith. And (...) he argues that James's pragmatic account of religion is based on an ethical view of the function of religion and a realist view of the objects of religious belief and experience, and is compatible with his larger conception of pragmatism. The book will appeal to readers interested in the history of modern philosophy, especially pragmatism, as well as those interested in moral philosophy, religion, and the history of ideas. (shrink)
With this book, Jacques Barzun pays what he describes as an "intellectual debt" to William James—psychologist, philosopher, and, for Barzun, guide and mentor. Commenting on James's life, thought, and legacy, Barzun leaves us with a wise and civilized distillation of the great thinker's work.
Every scholar and reader of William James is aware of his frequent uses of "energy," especially in his discussions of ethics and most notably in his 1906 Presidential Address to the American Philosophical Association, "The Energies of Men".[1] But while other interpretations treat James's use of "energy" as merely one of his several folksy metaphors, The Ethics of Energy: William James's Moral Philosophy in Focus is the first monograph, as its author, Sergio Franzese, rightly claims, to focus upon (...) "energy" as a central concept in James's ethics. Ethics, for James, is not about values, goods, or principles but about the organization of energy, especially into habits, in the service of personal, aesthetic ideals. As such this book is an original and valuable addition to the literature on James, and it does much to bring James into closer dialogue with other recent efforts to rethink ethics without appeal to some rule of reason, whether it be in the form of an utilitarian calculus or a categorical imperative. Such efforts include those of Friedrich Nietzsche, whom Franzese discusses extensively, Max Scheler, whom he mentions only briefly (51-52), and especially Michel Foucault, whom he does not mention at all.

William James is notorious for the large number of inconsistencies and at least apparent contradictions in his writings. Many readers conclude that he should be appreciated more for his profound but erratic insights than for any coherent philosophical perspective. Ellen Kappy Suckiel disagrees. She argues that James is far more careful and systematic than many readers realize. Her work on James is guided by the attempt to lay bare his coherent philosophical vision and the consistent philosophical methodology underlying it. (...) As a result of this approach, Suckiel's work on James is both sympathetic to his philosophical insights and carefully argued. In her first book, The Pragmatic Philosophy of William James (1982), Suckiel applies this approach to James's philosophy as a whole. The result is a work of remarkable clarity and insight that serves as a wonderful introduction to James's thought. In her more recent book, Suckiel applies this approach specifically to James's philosophy of religion, with similar felicitous results. Heaven's... (shrink)

The radical empiricism of William James was first formally presented in his seminal papers of 1904, 'Does Consciousness Exist?' and 'A World of Pure Experience'. In James's view, pure experience was to serve as the source for psychology's primary data and radical empiricism was to launch an effective critique of experimentalism in psychology, a critique from which the problem of experimentalism within science could be addressed more broadly. This collection of papers presents James's formal statements on radical empiricism and (...) a representative sample of contemporary responses from psychologists and philosophers. With only a few exceptions, these responses indicate just how badly James was misread - psychologists ignoring the heart of James's message and philosophers transforming James's metaphysics into something quite unintelligible to the emerging generation of experimental psychologists.

I should like to convey to you some doubts which have occurred to me on the subject of the notion of consciousness that prevails in all our treatises on psychology.
It was important to James's philosophy, especially his doctrine of the will to believe, that we could believe at will. Toward this end he argues in The Principles of Psychology that attending to an idea is identical with believing it, which, in turn, is identical with willing that it be realized. Since willing is identical with believing and willing is an intentional action, it follows by Leibniz's Law that believing also is an intentional action. This paper explores the problems with (...) James's thesis that attending=will=belief. An attempt is made to show that it has a salvageable core that is of considerable philosophical interest and importance. (shrink)
The concept of empiricism evokes both a historical tradition and a set of philosophical theses. The theses are usually understood to have been developed by Locke, Berkeley, and Hume. But these figures did not use the term “empiricism,” and they did not see themselves as united by a shared epistemology into one school of thought. My dissertation analyzes the debate that elevated the concept of empiricism (and of an empiricist tradition) to prominence in English-language philosophy. -/- In the 1870s and (...) ’80s a lively debate about psychology emerged. Neo-Kantian idealists criticized the very idea that the mind can be studied scientifically. A group of philosopher-psychologists responded, often in Mind. They were among the first to call themselves “empiricists,” arguing that psychology could provide a scientific basis for philosophical progress. Idealists held that empirical psychology depended on premises developed by Locke, Berkeley, and Hume. These premises were allegedly absurd because they rendered ideas of extension, as well as other ideas crucial to natural science, unreal. Those who wanted to advance psychology towards becoming a legitimate science were forced to engage these philosophical attacks, while at the same time to develop empirical theories that could successfully explain some characteristics of experience. I show how James’s theory of space perception accomplished both tasks. -/- In developing this theory, James found he had to reject the Lockean notion that reality is associated with passively-registered sensations. James also abandoned Berkeley and Hume’s claim that ideas are ultimately derived from atomic sensations. Instead, James presented experimental evidence that sensation is a continuous stream. The mind must actively parse this stream if it is to gain a coherent representation of its environment. I argue that James’s stream-of-thought thesis served as a presupposition of his entire psychology. The thesis showed how the labor of investigating the mind could be divided between philosophers and scientists, and in a manner sensitive to the concerns of both. The stream thesis also provided a scientific basis for a new philosophical empiricism that, I argue, has a hidden legacy in the history of analytic philosophy. (shrink)
One way to understand philosophy as a form of therapy is this: it involves a philosopher who is trying to cure himself. He has been drawn into a certain philosophical frame of mind—the ‘disease’—and has thus infected himself with this illness. Now he is sick and trying to employ philosophy to cure himself. So philosophy is both: the ailment and the cure. And the philosopher is all three: pathogenic agent, patient, and therapist.
A brief (10,000 word) introduction to James's philosophy with particular focus on the relation between James's naturalism and his account of various normative notions like rationality, goodness and truth.

According to William Craig, the notion of explanatory priority is the Achilles' heel of Robert Adams' argument against Molinism. Specifically, Craig contends that (1) the notion of explanatory priority is employed equivocally in the argument; (2) Adams is guilty of conflating reasons and causes; and (3) one of the intermediate conclusions of the argument is invalidly inferred, as can be seen by a counterexample. I argue that Craig is mistaken on all counts, and that Adams' argument emerges unscathed.

Conclusion: "For Bergson, it will be remembered, there is a conclusion,...The conquest of death is implied metaphysically, not to be verified experimentally. Man is born at home in the world, a microcosm essentially at one with it. For James the difference of man from the world is the fundamental thing. He is not born at home in it, he makes a home of it.
A Pluralistic Universe is America's favourite philosopher's last complete work before he died in 1910. Nevertheless, it has been somewhat neglected as a final self-reckoning. Indeed the term "pragmatism" occurs pretty rarely in it, while "experience" and "pluralism" abound. As introduced and annotated by H.G.

The book focuses in particular on three key areas of his thinking: Democracy: his work in democratic theory - through his critical challenges to the (...) traditions of Rawlsian theories of justice and Habermasian theories of deliberative democracy - has spurred the creation of a fertile and powerful new literature Pluralism - Connolly's work utterly transformed the terrain of the field by helping to resignify pluralism: from a conservative theory of order based on the status quo into a radical theory of democratic contestation based on a progressive political vision The Terms of Political Theory - Connolly has changed the language in which Anglo-American political theory is spoken, and entirely shuffled the pack with which political theorists work.
