Summary
Owsei Temkin (1902–2002) was a German-born American historian of medicine who spent most of his career at Johns Hopkins, where he shaped the modern discipline of medical historiography. His major works—on Galenism, on Hippocrates in late antiquity, and on the philosophy of medicine—argued that medicine’s past can only be understood as intellectual and cultural history, not as a march toward scientific progress. His central contribution was to show that great medical authorities like Galen survived not through passive transmission but through continuous active reinterpretation across radically different cultures. Temkin also insisted that the historian of medicine occupies a double position—looking backward at the past and forward toward medicine’s present obligations—a tension he called the “double face of Janus.” He lived for a century, his scholarly life spanning from Weimar Leipzig to twenty-first-century Baltimore.
Life and Career
Owsei Temkin argued that the humanistic study of history, oriented toward man and his values, is needed in medical schools to complement the scientific education that deals with man statistically.(Temkin, 1977) He also described the history of medicine as a Janus head: one face looks backward with the historian’s eye to illuminate the past, the other looks forward with the physician’s eye toward practical utility.(Temkin, 1977) Temkin traced his own move from philosophy of medicine toward history of medicine to the influence of Ludwig Edelstein’s 1930 lecture on Hippocrates, which demonstrated that deep historical scholarship in one period was prerequisite to sound historiography of any period.(Temkin, 1977)
The intellectual encounter that decisively shaped his method was Ludwig Edelstein’s 1930 lecture on Hippocrates. Edelstein, a rigorous classical scholar, convinced Temkin “that interest in medicine could not substitute for sound historical scholarship, which was not to be acquired by ranging over the whole past. Exploration of one period in depth was needed, even if only to make one aware of the craftsmanship necessary for dealing with other periods.”(Temkin, 1977) Temkin took this lesson to heart: his three major monographs each engage their subject at uncommon depth.
After the Nazi rise to power, Temkin followed Sigerist to the Johns Hopkins Institute of the History of Medicine, where he spent the remainder of his working life. His first major monograph, The Falling Sickness (1945), traced the history of epilepsy from antiquity to the twentieth century. His four Messenger Lectures at Cornell in 1970 became Galenism (1973).(Temkin, 1973) Hippocrates in a World of Pagans and Christians (1991) appeared when Temkin was approaching ninety. He was an active presence in the field for most of the century. He feared, near the end of his career, that the professionalization of medical historiography into an autonomous academic discipline risked “the alienation of the medical professions” — producing communication for historians only and losing the discipline’s critical function toward medicine itself.(Temkin, 1977)
Intellectual Contributions
The Janus Metaphor and the Meaning of Medical History
The title essay of The Double Face of Janus (1977) takes its organizing image from Henry Sigerist’s preface to Kyklos: “The history of medicine has a Janus-head. One face looks to the future with the eyes of the physician, the other one is turned backward. With the eyes of the historian it tries to light up the darkness of the past.”(Temkin, 1977) Temkin adopted this as a genuine methodological problem. The medical historian occupies two roles simultaneously, and their tension is productive rather than resolvable. If one yields entirely to historicism—insisting that past events can only be understood within their own conceptual framework—the result is “the end of all communication between the ages and a surrender of the invariance of scientific laws.”(Temkin, 1977) If one imports modern categories without care, the past becomes merely a distorted mirror of the present.
Temkin resolved the tension through a deliberately broad definition of medicine: not applied biology, not applied science, but “healing (and prevention) based on such knowledge as is deemed requisite. Such knowledge may be theological, magic, empirical, rationally speculative, or scientific.”(Temkin, 1977) This opened the historical record to forms of healing that narrower definitions would exclude, and it allowed Temkin to argue that the “meaning of medicine in historical perspective” could not be reduced to the history of correct theories. Medicine has been meaningful to society even when it could not cure disease, functioning as “a social institution, a response, in other than purely spiritual forms, to the need for aiding the sick and protecting the healthy. Radical cure is an ideal that may or may not be realized.”(Temkin, 1977)
Across his essays, Temkin described three historically distinct roles that the physician had occupied: the Hippocratic healer responsible to the individual patient; the physician-scientist seeking universal knowledge for all mankind; and the public-minded physician concerned with community health. These roles were “not necessarily in complete harmony,” Temkin noted, but they shared the common aim of health.(Temkin, 1977) He connected this to the history of therapeutic nihilism in the mid-nineteenth century, which he read as a development that “helped to undermine the notion that medicine was the domain of physicians only” by making the life of a medical scientist — one who treats no patients — socially legitimate.(Temkin, 1977)
Galenism: Authority Through Adaptation
In Galenism (1973), Temkin argues that Galen exercised medical authority for more than thirteen hundred years.(Temkin, 1973) Temkin’s method was explicitly reception-historical: his aim was “to present those aspects of Galen that will make the reactions of later centuries understandable,” treating Galen “in the light of what was to come.”(Temkin, 1973)
His physiology centered on a four-element scheme linked to four humors; his doctrine of temperaments enumerated nine possible qualitative mixtures organized around deviations from an ideal balance.(Temkin, 1973)(Temkin, 1973) His method combined rational deduction with insistence on experience: pure empiricism was unreliable because its allegedly constant results were “due to chance,” but pure rationalism without experience was equally insufficient.(Temkin, 1973) Galen also found the highest form of piety in anatomical investigation itself, holding that nature had arranged matter in a fashion that human thought could not improve upon.(Temkin, 1973)
By around A.D. 350, Galen’s position as the leading medical authority was “clearly established,” with Alexandria as the center of Galenic teaching.(Temkin, 1973) The Alexandrian iatrosophists established a canon of sixteen Galenic writings to be read and commented upon.(Temkin, 1973) This canon shaped all subsequent reception: medieval Western Galenism received not Galen as he wrote but “a medical philosophy twice removed from him, viz., through the activities of Byzantines and Arabs.”(Temkin, 1973)
In the Arabic world, Temkin traced a consistent pattern: Galen was accepted as supreme medical authority while his philosophical authority—in logic, physics, metaphysics—was contested.(Temkin, 1973) Maimonides catalogued doubts about Galenic statements in twenty-five aphorisms, arguing that Galen “has to be followed” in medicine “but his opinions ought to be followed only in medicine and in nothing else.”(Temkin, 1973) Rhazes justified his own departures from Galen by appealing to Galen’s own insistence on truth: “it is more in the spirit of Galen to follow his exhortation to search for truth than it is to swear by his opinions.”(Temkin, 1973) Temkin read this Razian move as exemplary—Galenism was resilient because it contained within itself the resources for self-criticism.
The fall, when it came, was processual rather than sudden. “Galenism as a science could hardly have survived past the middle of the seventeenth century, but as a guide to medical practice Galenism did survive in spite of the new philosophy.”(Temkin, 1973) Vesalius’s Fabrica (1543) broke Galen’s anatomical supremacy by demonstrating that his anatomy was based on animal dissection.(Temkin, 1973) Harvey’s demonstration of the circulation of the blood in 1628 proved Galen’s medical science untenable at its foundation.(Temkin, 1973) Yet Galenic practice—bleeding, purging, dietetics, galenicals—outlasted the theoretical refutations because practitioners had no reason to think it had “stopped preventing and curing diseases.”(Temkin, 1973) By 1870, Galen was “gently and quietly, but none the less resolutely, handed over to classicists, Arabists, and historians for disposal in the cemetery of the great dead.”(Temkin, 1973)
One of Temkin’s subtler arguments concerned how Galenism was destroyed from within. Sanctorius’s use of the thermometer to measure Galenic qualities inadvertently destroyed them by substituting quantitative degree for objective hot and cold. Temkin called this — borrowing from Hegel — “the cunning of the concept, whereby a harmless-looking device effects the downfall of the subject.”(Temkin, 1973)
The Layered Hippocrates
In Hippocrates in a World of Pagans and Christians (1991), Temkin defined “Hippocrates” broadly to include the historical person, any author of the Hippocratic Corpus, and the entire tradition of medicine looking to Hippocrates for inspiration.(Temkin, 1991)
Temkin defined “Hippocrates” deliberately broadly: the historical person born on Cos around 460 BCE, the authors of the approximately sixty works in the Hippocratic Corpus, and the entire tradition of medicine looking to Hippocrates for inspiration.(Temkin, 1991) By the first century CE, Hippocratic followers had split into two main sects: Dogmatists (or Logicians), who saw Hippocrates as the founder of a scientific medicine grounded in hidden causes, and Empiricists, who saw him as a great clinical teacher relying on experience rather than speculation.(Temkin, 1991) Galen’s major historical contribution was to reject sectarianism in favor of “a single medical science, guided exclusively by the search for what reason and experience proved to be true”(Temkin, 1991) — a synthesis that fixed Hippocrates-as-seen-through-Galen as the authoritative image in the later Empire.
The epilogue traces how this image changed under Christianity. Hippocrates “maintained his authority, yet his cultural significance diminished. Neither in the East nor in the West did Christians need a pagan culture hero.”(Temkin, 1991) An anonymous late preface to the Aphorisms presented Hippocrates as “nature incarnate” fulfilling a divine mission to save mankind — an unintentional parallel to the Johannine Word made flesh, creating “a christianized Hippocrates.”(Temkin, 1991) Temkin’s concluding claim carried wide reach: “Throughout the world of pagans and Christians, Hippocrates represented the autonomy of medicine as a sphere of life. Naturalistic medicine sided with the majority of people — for whom eating, drinking, procreating, and the other activities were part of normal life.”(Temkin, 1991) The Hippocratic doctor’s traditional science remained intact after Christian conversion; what shook the world “did not shake everything in it in equal measure.”(Temkin, 1991)
Byzantine Medicine and the Structure of Scholastic Galenism
The essay “Byzantine Medicine: Tradition and Empiricism” (1962), collected in the Double Face volume, provides Temkin’s most detailed account of how Galenism became an institutional teaching system.(Temkin, 1977) The Alexandrian iatrosophists — teachers of medicine who were also Neoplatonist philosophers — selected sixteen Galenic texts for commentary and systematized them following the Neoplatonic pedagogical model of beginning with Porphyry and Aristotle. Their commentaries introduced Galen to the Islamic world through Syriac and Arabic intermediaries, and to the Latin West through independent translations.(Temkin, 1977) Galen’s On the Use of Parts became central because it could be read as natural theology praising the divine perfection of the human body, making it acceptable to Neoplatonists and Christians alike.(Temkin, 1977) The result was that Galenism entered the medieval world not as a set of observations about nature but as a scholastic system — selecting, commenting on, and summarizing a fixed canon.
Reception and Legacy
Temkin is generally recognized as one of the architects of medical historiography as an academic discipline in the United States. His reconstruction of Galenism as a living, adaptive tradition—not a dead weight of authority that scientists eventually threw off—influenced subsequent scholarship on the sociology of scientific knowledge and the reception of canonical texts. Vivian Nutton’s Ancient Medicine (2023) takes for granted the methodological priority Temkin established: that the triumph of Galenism in late antiquity led to the marginalization and eventual loss of competing traditions, including the Empiricists and Erasistrateans, “which had flourished from 250 BCE for almost 500 years.”(Nutton, 2023) Galenism itself remains the standard treatment of its subject and is cited in virtually every subsequent account of the long-term fate of Galenic medicine.
The contested dimension of Temkin’s legacy lies in its relation to structuralist and poststructuralist approaches to medical history. Foucault’s Birth of the Clinic (1963) analyzed the same epistemological transformations Temkin tracked—the rise of pathological anatomy, the new relation between disease and death—but from a perspective concerned with power relations and discursive formations rather than intellectual transmission. These approaches are not simply alternative frameworks but constitute a genuine disagreement about what counts as an explanation in the history of medicine.
Temkin’s argument that medicine cannot be defined as applied biology also remains live. His broader conception—medicine as healing based on whatever knowledge is deemed requisite—defines the subject broadly enough to include traditions that laboratory-based medicine has systematically excluded. Whether this breadth is intellectual generosity or a category error remains a point of contention.
