William James

William James (1842–1910) was an American philosopher, psychologist, and physician whose work at Harvard helped establish psychology as an independent discipline and reshape how educated Americans thought about health, religion, and the mind. Trained in medicine, he suffered years of illness and depression before arriving at a philosophy of practical action that he called pragmatism: the view that ideas are true insofar as they help us get into satisfactory relations with the world. His Principles of Psychology (1890) placed consciousness and emotion squarely in the body, while his Varieties of Religious Experience (1902) gave academic respectability to the study of healing through faith and mind. James also coined the term “medical materialism” as a critique of reductive explanations of religious life. His concepts — the stream of consciousness, once-born versus twice-born personalities, healthy-mindedness — traveled through the twentieth century into medical anthropology, narrative medicine, and the history of emotion.

Medical Training and the Crisis of Vocation

James studied medicine at Harvard, receiving his MD in 1869, but never practiced. His 1860s were marked by years of profound illness, depression, and uncertainty about whether life was worth living — a personal crisis he eventually described through philosophical categories. His reading of the French neo-Kantian Charles Renouvier, who argued that free will was real and that one could simply decide to believe it, gave James a way to break free of the fatalism implied by the biophysical materialism then dominant in European science.

That materialism had a precise institutional face. The Berlin Physical Society, formed in 1847 by Du Bois-Reymond, Helmholtz, Brücke, and Ludwig, had declared that all of human life, including psychology, could be fully explained by chemical and physical processes alone, with no room for immaterial vital forces or causal mental events.(Makari, George, 2008) Their program, which treated psychic events as mere side-effects of reflex action incapable of themselves causing biological events, had spread into the Vienna of Meynert and into the training that the young Freud received. James was aware of this program and its clinical ramifications.

He honored Theodor Meynert — the Viennese neuroanatomist who attempted to ground all of psychology in a two-tiered reflex model — by placing his work at the beginning of the Principles of Psychology. But James rejected Meynert’s conclusions: any adequate psychology must preserve a causal role for ideas and feelings, which the biophysical model explicitly denied.(Makari, George, 2008) Translating Meynert’s system “back into pure psychology,” as James put it, recovered whatever psychological truth it contained without entangling the reader in what James saw as dubious anatomy.

This was not merely a technical dispute. If ideas and feelings could not cause anything — if they were mere epiphenomena of neural reflexes — then the clinical encounter had no room for the patient’s inner life as a causal factor in health and disease. James’s defense of psychic causation was, in this sense, a defense of a certain kind of medicine: one in which what the patient thinks and feels matters not just ethically but mechanically, as a real input into the biological processes that determine health.

The Principles of Psychology and the Body

The Principles of Psychology (1890) addressed the central question of how mind relates to body by locating mental life firmly in physiology without reducing it to mechanism. James’s contribution to emotion theory was especially consequential. He and the Danish physiologist Carl Lange, independently and simultaneously, proposed that bodily changes are not the effect of emotions but are the emotions themselves — what we call fear is the perception of racing heart and cold sweat, not an inner feeling that precedes these changes.(Maciocia, Giovanni, 2009) This reversal — we do not cry because we are sad; we are sad because we cry — placed the body at the center of emotional experience in a way that anticipated twentieth-century somatic therapies and the psychophysiology of stress.

The theory also carried philosophical weight. If emotional experience is essentially the perception of bodily state, then there is no sharp line between body medicine and mind medicine. The James-Lange account made healing interventions that act on the body also interventions that act on the emotions, and vice versa. Maciocia later noted that the James-Lange framework presents interesting parallels with Chinese medicine’s understanding of emotion as inseparable from movement of qi, in which anger makes qi rise and fear makes it descend.(Maciocia, Giovanni, 2009) The parallel is not incidental: both James and the classical Chinese tradition are committed to the inseparability of somatic and psychic change, against any model that treats emotion as a purely mental event that merely accompanies, or merely results from, bodily processes.

James also distinguished two fundamentally different kinds of thinking: reasoning on one hand, and what he called narrative, descriptive, and contemplative thinking on the other, arguing that rationality was larger than scientific hypothesis and verification.(Montgomery, 2006) This distinction proved useful in later philosophy of medicine: it implied that clinical thinking cannot be reduced to inference from evidence, and that the narrative rationality physicians use to make sense of cases belongs to a legitimate cognitive register — one that operates by rules of evidence and internal consistency, even if those rules are not the same as experimental logic.

Pragmatism and Medical Knowledge

James’s pragmatism argued that the truth of any belief is determined by its practical consequences — an idea has value insofar as it makes a difference to how we live. Applied to medicine, this orientation shifted the question from “Is this theory scientifically correct?” to “Does acting on this belief lead to better outcomes?” It also had a critical edge: the biophysical materialism of Meynert and Brücke was not simply wrong in James’s view, it was practically inadequate — a theory that could not account for the causal role of ideas and feelings could not guide clinicians who needed to actually help patients.

In the philosophy of clinical reasoning, physicians share narrative rationality with lawyers, detectives, and moral reasoners; in each field, a set of circumstances is called a ‘case,’ and the rational procedure determining what any case is a case of is neither induction nor deduction but C. S. Peirce’s abduction.(Montgomery, 2006) William James described rationality as larger than scientific hypothesis and verification, distinguishing ‘reasoning’ from ‘narrative, descriptive, contemplative thinking.’(Montgomery, 2006)

Jonsen notes that throughout the nineteenth century there was an almost total separation between moral philosophy and medicine in America, with moral philosophers rarely engaging medical problems directly.(Jonsen, 2000) [GAP: Claim that William James was an exception, with his engagements coming through psychology and philosophy of religion] [GAP: Claim that the gap began to close by James’s death and that his pragmatic framework made that closing possible]

The Varieties of Religious Experience and Healing

James’s Varieties of Religious Experience (1902) assembled first-person accounts of conversion, mystical states, saintliness, and the religion of healthy-mindedness to make a pragmatist argument: religious experience, whatever its metaphysical status, is real in its effects, and those effects sometimes include healing. The book was the most sustained academic engagement with faith healing and mind-cure in the American scholarly tradition.

James coined the term “medical materialism” for the debunking move that explains away religious experience by identifying its neurological or psychological substrate — diagnosing St. Paul’s vision on the road to Damascus as epilepsy, or St. Teresa’s ecstasy as hysteria.(Mary Douglas, 1966) For James, this move was fallacious: the medical cause of an experience tells us nothing about its value or its truth. The same logic would dismiss Beethoven’s deafness as evidence against his music.

James identified the religion of “healthy-mindedness” — the American New Thought tradition’s emphasis on positive thinking and the divinity of the mind — as “the only decidedly original contribution of the American people to the philosophy of life.”(Haller, 2014) Crucially, his attention to this tradition was pragmatic rather than credulous: these non-reductionist healing therapies sometimes worked, and that fact demanded explanation rather than dismissal. He also recognized the limits of healthy-mindedness, writing (as Douglas later quoted) that systematic healthy-mindedness, failing as it does to accord to sorrow, pain, and death any positive attention, is formally less complete than systems that try to include these elements in their scope.(Mary Douglas, 1966)

James used the categories “once born” and “twice born” to distinguish temperamental orientations toward the world. Once-born souls are native optimists for whom life is basically good and religion confirms that goodness; twice-born souls have passed through a dark period — the sick soul’s experience of meaninglessness or despair — and arrived at faith only through struggle. These were not merely religious types for James; they were phenomenological descriptions of how different people stand in relation to suffering and negativity. Kleinman adapted these categories directly for chronic illness, arguing that the experience of serious disease often converts once-born patients into twice-born ones: it teaches that beneath the facade of optimism there runs a darker stream of undeserved suffering that must be lived through, not explained away.(Kleinman, 1988) This is a claim about the moral education that chronic illness delivers, and it connects the clinical encounter to the long philosophical tradition — from the Psalms to Kierkegaard — of treating affliction as a school for deeper apprehension of reality.

Mind-Cure and the Will to Believe

James had personal experience with neurasthenia — the late nineteenth-century diagnosis of nervous exhaustion associated with the demands of modern civilization, which George Beard had identified shortly after the Civil War.(Kleinman, 1988) His Will to Believe (1897) argued that in certain forced, live, and momentous options — situations where one must act and where the evidence is insufficient to compel a choice — it is rationally permissible to let one’s hope and desire influence belief. Applied to health, this meant that choosing to believe in one’s recovery, or in the efficacy of a treatment, was not mere wishful thinking but a legitimate exercise of practical reason with genuine physiological consequences.

William James characterized the American New Thought healing tradition as “healthy-mindedness,” calling it the only decidedly original contribution of the American people to the philosophy of life because non-reductionist healing therapies sometimes worked.(Haller, 2014) He viewed disease as much the outcome of physical forces as the result of the mind and emotions.(Haller, 2014)

Shoma Morita, who developed a Japanese psychotherapy for anxiety disorders in the early twentieth century that engaged directly with James’s stream-of-consciousness concept, was a contemporary of James working from a very different tradition.(Shoma Morita (trans.), 1998) Morita challenged James’s stream of consciousness by contending that consciousness is transitory and ever-changing rather than a continuous flow — a disagreement that illustrates how widely James’s psychological concepts traveled across national and cultural boundaries.

James and Psychical Research

James took psychical research seriously throughout his career. His approach was consistent with his wider pragmatism: if extraordinary mental phenomena — telepathy, trance states, clairvoyance — had measurable effects in the world, they warranted serious investigation rather than dismissal on a priori grounds. James maintained careful agnosticism rather than either credulity or reflexive skepticism, a stance his medical contemporaries found uncomfortable. The psychologie nouvelle that had swept France in the 1880s — the school that combined associationalism, hereditary theory, and psychopathology and had drawn the young Freud to Paris — had emerged from precisely this intersection of mainstream medicine and the study of altered states, automatisms, and somnambulism.(Makari, George, 2008) James was in sustained conversation with this French tradition and with the researchers on its edges who were cataloguing the same phenomena under different labels.

The controversy over psychical research illustrated the broader tensions in James’s intellectual position. He believed that any psychology adequate to human experience had to be able to account for the full range of what human beings actually reported — including states that the materialist framework of his colleagues ruled out as impossible rather than merely unconfirmed.

Influence on Medical Thought

James spent his entire academic career at Harvard, where President Charles Eliot’s 1869 reforms had rebuilt medical education around laboratory science, extended training, and required examinations.(Starr, 1982) James taught in both the philosophy and psychology departments, and his presence at a school whose medical faculty was simultaneously becoming one of the leading centers of scientific medicine in America gave him continuous proximity to the tensions between humanistic and reductionist approaches to human beings. He was trained as a physician, he thought seriously about mind-body questions, and he maintained connections with the medical world throughout his life — but he wrote as a philosopher, which meant his medical influence was almost entirely indirect, transmitted through concepts that later clinicians and theorists found useful and appropriated.

James’s influence on twentieth-century medical thought operated through several indirect channels. Thomas Kuhn, writing in 1962 on paradigm-dependent perception, cited James’s phrase “a blooming buzzing confusion” to describe the state of perceptual experience before a paradigm provides categories for organizing it.(Kuhn, 1962) This appropriation was fitting: James had argued that perception is always shaped by prior concepts and expectations, a view that mapped directly onto Kuhn’s account of how scientists see differently depending on their theoretical commitments.

Arthur Frank, developing a narrative theory of illness at the end of the twentieth century, invoked James’s concept of the “really real” when describing what wounded storytellers accomplish: their accounts provide glimpses of underlying experience that reenchant a world that chronic illness and medical institutions have disenchanted.(Frank, 1995) The connection between James’s radical empiricism — his insistence that relations and conjunctions, not just discrete facts, are part of the given — and the phenomenological attention to lived experience that characterizes narrative medicine is philosophically coherent even when it is not explicitly acknowledged.

In the philosophy of clinical reasoning, James’s two-kinds-of-thinking distinction — reasoning versus narrative, descriptive, and contemplative thought — anticipated debates about whether evidence-based medicine exhausts the rational resources available to clinicians.(Montgomery, 2006) Montgomery’s account of clinical judgment as narrative rationality stands in a pragmatist tradition James helped establish.

Freud’s only academic honor in his lifetime was the honorary degree from Clark University in 1909, which he attended reluctantly and partly at Jung’s urging.(Andrew Scull, 2015) Despite his deep distrust of America, the United States became the country where psychoanalysis achieved its greatest and most lasting institutional foothold.(Andrew Scull, 2015)

James’s descriptions of melancholic subjectivity also entered psychiatric historiography. Radden notes that James’s account of the sick soul’s subjective experience — the world loathing rather than purely self-loathing that characterized the twice-born’s dark passage — aligns more closely with Kraepelin’s clinical descriptions of melancholia simplex than with Freud’s later emphasis on self-loathing and internalized loss in “Mourning and Melancholia.”(Radden, Jennifer (ed.), 2000) This alignment suggests that James was working from the same phenomenological terrain as the Kraepelinian nosologists, even though his goals were philosophical and religious rather than clinical.

The demedicalization of nostalgia, which accelerated in the 1880s and 1890s, depended partly on the shift James embodied. His 1884 essay on the physiological theory of emotion helped reframe emotional experiences like homesickness as naturalized instinctual drives rather than distinct clinical diseases — processes innate to human nature rather than pathological conditions requiring diagnosis and treatment.(Thomas Dodman, 2018) The demedicalization of nostalgia is therefore not merely an administrative change in psychiatric classification but a symptom of the broader shift toward physiological and psychological rather than strictly somatic accounts of emotion that James helped drive.
