Method of Medicine, a systematic and comprehensive account of the principles of treating injury and disease and one of Galen's greatest and most influential works.

Galen dominated medicaltheory and practice until the scientific revolution and beyond, through the medieval Schools, and through his influence on Muslim medicine.This is the first major selection of Galen's work in English.

'A fascinating book. It contains a sweeping survey of approaches to causation and explanation from the Presocratic philosophers to the Neo-platonist philosophers. Hankinson pays a visit to every major figure and movement in between: the sophists, Plato, Aristotle, the Stoics, the Sceptics, the Epicureans and a variety of medical writers, early and late... impressive... Hankinson's observations are regularly intriguing, at times refreshingly trenchant, and in some cases straightforwardly arresting... the history itself is excellent: clear, intelligently conceived and executed, and broadly (...) accessible. Those in search of a philosophically astute history of clasical philosophy given in terms of one of its own central unifying obsessions will delight in reading R. J. Hankinson's work.' -Christopher Sheilds, Times Literary SupplementR. J. Hankinson traces the history of ancient Greek thinking about causation and explanation. He examines how the Greeks dealt with questions about how and why things happen as and when they do, about the basic constitution and structure of things, about function and purpose, laws of nature, chance, coincidence, and responsibility. Such diverse questions are unified by the fact that they are all demands for explanation, for an account of the world that will render it amenable to prediction and control. (shrink)

This article is an attempt to present the critics that Galen made against ancient atomist theory based largely on his theory of elements. For Galen, the problem of irreducible complexity in nature can’t be explained by the atomist theory, especially when the issue is concerned with a metaphysical discussion in the context of philosophy of nature. Yet for him the subject of change in nature was not explicitly formulated by proponents of atomism. For this being the case, by (...) criticizing atomism, Galen tries to formulate a syncretic theory which is mostly an amalgamation of Aristotle and Hippocrates’ views. His theory is a frame in which like-elements affect the likes through a presupposed ‘leap’ between them that is largely related to krasis; which eventually makes the change, bodily sensibility and lastly the pain possible. Therefore, it is imperative that one embraces a transient theory like that of the combination of Aristotle-Hippocrates’s, instead of a closed-theory such as atomism. Taken into consideration from the point of philosophy of nature, Galen would come to the terms with a teleological causality instead of mechanical one. All combined, Galen’s mentioned understandings has led him to bring serious criticism against the atomist theory which can be seen as the extension of his medical-philosophy project. (shrink)

Determining what has gone wrong in a malfunctioning body and proposing an effective treatment requires expertise. Since antiquity, philosophers and doctors have wondered what sort of knowledge this expertise involves, and whether and how it can warrant its conclusions. Few people were as qualified to deal with these questions as Galen of Pergamum. A practising doctor with a keen interest in logic and natural science, he devoted much of his enormous literary output to the task of putting medicine on firm (...) methodological grounds. At the same time he reflected on philosophical issues entailed by this project, such as the nature of experience, its relation to reason, the criteria of truth, and the methods of justification. This volume explores Galen's contributions to epistemology, as they arise in the specific inquiries and polemics of his works, as well as their legacy in the Islamic world. (shrink)

Moulages are contact media – images made by contagion in the most literal sense: their production relies on a process in which the object to be reproduced is touched by the reproducing material. In the case of dermatological moulages, the plaster touches the infected skin of the sick and, once dried, serves as the negative form for the waxen image of a disease. Focussing on the collection of the Hôpital Saint-Louis in Paris, the article situates the production of dermatological (...) moulages within the visual culture of 19th-century medicine and raises the question how an ancient technique of image production could become such a prevalent tool for the documentation of skin diseases during a period usually associated with the rise of scientific medicine and a reconsideration of theories of contagion in medical aetiology.

The outbreak of syphilis in Europe elicited a variety of responses concerning the disease's origins and cure. In this essay, I examine the theory of the origins of syphilis advanced by the 16th-century Italian surgeon Leonardo Fioravanti. According to Fioravanti, syphilis was not new but had always existed, although it was unknown to the ancients. The syphilis epidemic, he argued, was caused by cannibalism among the French and Italian armies during the siege of Naples in 1494. Fioravanti's strange and novel (...) theory is connected with his view of disease as corruption of the body caused by eating improper foods. His theory of bodily pollution, a metaphor for the corruption of society, coincided with Counter-Reformation concepts about sin and the social order. (shrink)

An ancient doctor who advocated the therapeutic benefits of wine and passive exercise was bound to be successful. However, Asclepiades of Bithynia did far more than reform much of traditional Hippocratic therapeutic practice; he devised an extraordinary physical theory which he used to explain all biological phenomena in uniformly simple terms. His work laid the theoretical basis for the anti-theoretical medical sect called Methodism. For his trouble he was despised by his intellectual progeny and, more importantly perhaps, by Galen. (...) None of his work survives intact, but copious ancient testimonia relating to him allow us to reconstruct many details of the theory. His ideas offer us a fascinating glimpse of how Hellenistic philosophy and medicine interacted, and provide an introduction to one of the most intriguing doctrinal disputes in Greek science.

Epicureanism is not only a defence of pleasure: it is also a philosophy of science and knowledge. This edited collection explores new pathways for the study of Epicurean scientific thought, a hitherto still understudied domain, and engages systematically and critically with existing theories. It shows that the philosophy of Epicurus and his heirs, from antiquity to the classical age, founded a rigorous and coherent conception of knowledge. This first part of a two-volume set examines more specifically the contribution of Epicureanism (...) in the fields of language, medicine, and meteorology (i.e., celestial, geological and atmospheric phenomena). Offering a renewed image of Epicureanism, the book includes studies on the nature of human language and on the linguistic aspects of scientific discourse; on the relationship between Epicureanism and ancient medicine, from Hippocrates to Galen; on meteorological phenomena and the method of explaining them; and on the reception of Epicurus's legacy in Gassendi.

The issue of humoral temperament (mizāj) is mainly a subject of the field of medicine, but it has also been a subject of psychology, philosophy and moral philosophy during time. As the issue is ontologically related to the human nature, it has been dealt from many different perspectives. Within these disciplines, it has been expanded and developed during the historical process. It holds a wide range of literature as it is a rooted and ancient subject analysed within different disciplines. (...) Stretching out to the time of ancient Egypt, this theory was developed in the field of medicine by Hippocrates and by Galen in biology and it was a subject of some of the works of many Muslim scholars, first and foremost Jāḥiẓ, The issue of mizāj, first of all was explained by the theory of four composition (blood, mucus, yellow bile and black bile) Whether the amount of these liquids change within the body has always been an issue of debate according to the conditions of time and the place. Jāḥiẓ, impressed by the views of Galen, has no distinct piece of work on the issue of mizāj. However, he had put forward his views on the changes of the mizāj in some of his works but as he had unarranged writing style, he did not deal with these issues systematically. In this article, we have aimed at systematizing his views, determined in some of his own works and the studies on them, in two stages. What we mean by the change in mizāj is the point of disappearing of the ill temper and bringing good nature instead. Jāḥiẓ, considers the person as the subject of the effort to change the mizāj and evaluates this in two stages. For him, first of all, the person sinks herself into a mental effort. In this process, the person passes through the processes of remembrance, undertaking a task and suggestion. On this point, for abandoning the evilness and adopting the goodness in character, he underlines the importance of reason. Then, are these processes to change the mizāj for Jāḥiẓ are enough? Jāḥiẓ, invites the person to a second effort, accepting the person could feel hardship on the process, based on the analyses of observation and experiment. For this reason, getting a support from outside is proper for him. According to Jāḥiẓ, religion, education, being within the society and political authority are the factors affecting the change in the mizāj. Jāḥiẓ, brings forward views in an approach of taking away almost a general taboo within the society like “once a something always a something”. In an understandable and open wording, he conveys us the stance that the mizāj can change and its applicable within the daily life. In this study, the views of Jāḥiẓ, on the mizāj was evaluated in two stages, the temperament of the person was evaluated on the ground of the change of morality and was considered according to the contributions to the field of Kalam.

This lucid book is the first to be wholly dedicated to Hume's theory of personal identity, and presents a bold new interpretation which bears directly on ...

In this revised and updated edition of The Secret Connexion, Galen Strawson explores one of the most discussed subjects in all philosophy: David Hume's work on causation. Strawson challenges the standard view of Hume, according to which he thinks that there is no such thing as causal influence, and that there is nothing more to causation than things of one kind regularly following things things of another kind. He argues that Hume does believe in causal influence, but insists that we (...) cannot know its nature. The regularity theory of causation is indefensible, and Hume never adopted it in any case.

The intellectual history of evolutionary theory really does not begin in earnest until the late seventeenth/early eighteenth century. Prior to that, the idea that species might have evolved over time was not a serious possibility for most naturalists and philosophers. There is certainly no substantive debate in antiquity about evolution in the modern sense. There were really only two competing explanations for how living things came to have the parts they do: design or blind chance. Ancient Greek Atomism, (...) for example, taught that all composite bodies, including living things, are generated through the random collision of atoms as they rebel and move in the void. Plato and Aristotle both dismissed this possibility on the grounds that living things are too complex and too well-adapted to be products of chance. This eventually became the central premise in Galen’s own Argument from Design. That species forms might have gradually evolved over time by a process of natural selection was not seen as a plausible alternative. Of course, such a theory had been proposed by Empedocles in the fifth century BCE. But because his theory still relied heavily on chance, it was not taken seriously by any of the later ancient Greek or Roman thinkers. My aim in this paper is to investigate the reasons why evolutionary thinking failed to gain momentum in antiquity after its introduction by Empedocles. (shrink)

Clarendon Later Ancient Philosophers General Editors: Professor Jonathan Barnes, Balliol College, Oxford, and Professor A. A. Long, University of California, Berkeley This series, which is modelled on the familiar Clarendon Aristotle and Clarendon Plato Series, is designed to encourage philosophers and students of philosophy to explore the fertile terrain of later ancient philosophy. The texts will range in date from the first century BC to the fifth century AD, and they will cover all the parts and all the (...) schools of philosophy. Each volume will contain a substantial introduction, an English translation, and a critical commentary on the philosophical claims and arguments of the text. The translations will aim primarily at accuracy and fidelity; but they will also be readable and accompanied by notes on textual problems that affect the philosophical interpretation. No knowledge of Greek or Latin will be assumed. Galen's On the Therapeutic Method, written late in his life, represents the distillation in its most complete form of Galen's views on the nature, genesis, proper classification, and treatment of disease. It was one of the most widely read of all classical texts during the Middle Ages and the Renaissance, and formed the core of the medical curriculum until the seventeenth century. Although still deeply influential in the nineteenth century, it has been unjustly neglected in modern times. The work contains a fascinating collection of views on scientific terminology and taxonomy, the application of the logical methods of collection and division to science, the axiomatization of science, and the structure of causation. Consequently it is a key text in later Greek philosophy of science. R. J. Hankinson provides here the first translation into any modern language of the first two books, together with an introduction and a philosophical commentary. (shrink)

It is widely supposed that David Hume invented and espoused the "regularity" theory of causation, holding that causal relations are nothing but a matter of one type of thing being regularly followed by another. It is also widely supposed that he was not only right about this, but that it was one of his greatest contributions to philosophy. Strawson here argues that the regularity theory of causation is indefensible, and that Hume never adopted it in any case. Strawson maintains that (...) Hume did not claim that causation in the natural world is just a matter of regular succession, that such a dogmatic metaphysical claim about the nature of reality would have been utterly contrary to his fundamental philosophical principles, and that he rightly took it for granted that there was more to causation than regularity of succession, claiming only that regularity of succession was all that we could ever know of causation.

In a long-forgotten essay, Alvin Gouldner defended the distinctive contributions of Romantic social science. Today, half a century later, very few would risk making a similar plea. Owing to its deconstruction, the discourse of Romanticism has increasingly fallen out of favor in the social sciences, meaning social scientists have progressively come to see Romanticism as less a resource for critique than a bourgeois ideology warranting critical scrutiny. Yet the truth is quite a bit more complicated. For despite its disapproval at (...) the level of social science's explicit culture, Romanticism continues to serve, at the level of implicit culture, as a potent resource for social analysis. We start with a clarification of what we mean by Romanticism. While Romanticism may be an amorphous and multifaceted structure of thought and feeling, like Gouldner, we do not think it lacks coherence. Thus, we outline what we take to be the core dimensions of the ‘Romantic syndrome’, and then survey some of its key figures in Western social thought. Next, we move to a discussion of three select studies about the infiltration of Romanticism into the capitalist heartland—the sphere of work. We demonstrate how, consistent with our argument that Romanticism has become increasingly symbolically polluted within social science, each of these studies critiques the Romantic turn at work, while nevertheless anchoring their critiques in Romanticism, albeit in increasingly implicit fashion. We conclude by offering some reflections on why Romanticism continues to haunt contemporary social science—and why this matters. (shrink)

It’s opposed to separatism, which mistakes natural conceptual distinctions for ground-floor ontological differences.

Plato’s partition argument infers that the soul has parts from the fact that the soul experiences mental conflict. We consider an ambiguity in the concept of mental conflict. According to the first sense of conflict, a soul is in conflict when it has desires whose satisfaction is logically incompatible. According to the second sense of conflict, a soul is in conflict when it has desires which are logically incompatible even when they are unsatisfied. This raises a dilemma: if the mental (...) conflict is supposed to be the latter kind of conflict, then the partition argument is valid but is likely unsound; if it’s supposed to be the former kind, then the partition argument has true premises but is invalid. We explain this dilemma in detail and defend a dispositionalist solution to it. (shrink)

Aristotle, Dignāga, Descartes, Arnauld, Locke, Brentano, Sartre and many others are right about the nature of conscious awareness: all such awareness comports—somehow carries within itself—awareness of itself . This is a necessary condition of awareness being awareness at all: no ‘higher-order’ account of what makes conscious states conscious can be correct. But is very paradoxical: it seems to require that awareness be somehow already present, in such a way as to be available to itself as object of awareness, in order (...) to be constituted as awareness in the first place. Can anything relate to itself in this way? Can there be a relation that is necessarily one-term, reflexive, non-logical , concretely realizable, dynamically real, such that its holding is a necessary condition of the existence of the thing it holds of? It helps to consider the thought this very thought is puzzling. Many accept the reality of the kind of awareness of awareness posited in and , and think it must be not only ‘pre-reflective’ and ‘non-positional’, but also irrelational or non-intentional. But perhaps such awareness of awareness can be fully relational and fully intentional, and can be legitimately said to be its own object or content, even while being pre-reflective and non-positional.

This article begins with some brief reflexions on the definition of determinism (II), on the notion of the subject of experience (III), and on the relation between conscious experience and brain events (IV). The main discussion (V?XIII) focuses on the traditional view, endorsed by Honderich in his book A Theory of Determinism, that the truth of determinism poses some special threat to our ordinary conception of ourselves as morally responsible free agents (and also to our ?life?hopes'). It is argued that (...) this is half right: the truth of determinism does indeed threaten certain vital parts of our ordinary conception of ourselves as morally responsible free agents. The trouble is that the falsity of determinism does not diminish the threat in any useful way. The old, natural, and recurrent mistake is to think that we would really be better off, so far as free will and moral responsibility (and our ?life?hopes') were concerned, if determinism were false. It is argued that there is no important sense in which this is true, and that the question of whether determinism is true or false is therefore of no real importance, so far as the free will debate is concerned.

Panpsychism is a plausible theory of the fundamental nature of reality. It is fully compatible with everything in current physics, and with physicalism. It is an error to think that being physical excludes being mental or experiential. Anyone who endorses the following three views – [i] materialism or physicalism is true, [ii], consciousness is real, [iii] there is no ‘radical emergence’ – should at least endorse ‘micropsychism’ or psychism, the view that [iv] mind or consciousness is a fundamental feature of (...) concrete reality, already present in the most basic forms of concrete reality. And given [v] the interconvertibility (fungibility) of all fundamental forms of physical stuff, panpsychism appears to be the most plausible form of psychism. (shrink)

Nicholas Everitt's objection to my discussion of the regularity theory of causation is a common one. Ithink it misses the point, but the point it misses is in a way a delicate one, and hard to express, and the general worry he expresses is a natural one. For that reason it is important, and its importance is reflected in the fact that it is very difficult to find a satisfyingly substantive way of stating the difference between regularity theories of causation (...) and non-regularity theories of causation. I have had no new ideas about how to do this [...], but I will restate some of [my older] ideas [...], in order to try to answer Everitt [...]. (shrink)

Intentionality is an essentially mental, essentially occurrent, and essentially experiential phenomenon. Any attempt to characterize intentionality that detaches it from conscious experience faces two insuperable problems. First, it is obliged to concede that almost everything has intentionality—all the way down to subatomic particles. Second, it has the consequence that everything that has intentionality has far too much of it—perhaps an infinite amount. The key to a satisfactory and truly naturalistic theory of intentionality is a realistic conception of naturalism and a (...) properly developed understanding of the phenomenon of cognitive experience.

The aim of this article is to examine some of the anatomical implications of Campanella's theory of magic, focusing in particular on his crìtique of Aristotle's and Galen's anatomical views. By magic Campanella meant first and foremost communication of energy and knowledge. It is no accident that he viewed both medicine and rhetoric as constitutive disciplines of magic. In doing so, he appealed to the time-honoured notion of the magic of the word theorised in ancient times by the sophist (...) Gorgias. The distinctive feature in Campanella's system of magic is that the word is both a symbolic and a physical entity. Meaning flows from nature to the mind and from the mind to nature. Words are both carriers of meanings and physical agents of psychosomatic transformation. As can be demonstrated by pointing to such paradigmatic cases as natural divination and prophecy, the force of the imagination, the patient's trust in the power of the physician or the healer, and the many influences that air exercises on the body, Campanella's theory of magic rests on a definite anatomo-physiological basis. The most original aspect, though, is the way in which Campanella reinterpreted Arìstotle's and Galen's prìnciples of anatomy so that he could adapt his medical views to the broader framework of his theory of magic (practice), on the one hand, and metaphysics (theory), on the other. In addition, Campanella's onginal account of emotions and passions supported a comprehensive system of magical practice that dispensed with the basic principles of both Aristotle's and Galen's physiology. Campanella was convinced that the vital operations of the body could not be explained by simply relying on the unsentient functions of the vegetative soul (Aristotle) or on the natural faculties of the body (Galen), nor could they be accounted for by assuming the existence of incorporeal souls (Aristotle) or bodily temperaments (Galen). By circumventing both Aristotle's hylomorphism and Galen's vital matenalism of the temperaments, and by appropriating the Stoic view of rational pneuma, he managed to produce a physiological model that was more flexible in dealing with the complex interplay of knowledge, action and appetite, and above all, better suited to account for a universe in which the flow of life and meaning encompassed varìous levels of communication.

This paper considers Hume’s account of personal identity in his Treatise of Human Nature. It argues for three connected claims. Hume does not endorse a “bundle theory” of mind, according to which the mind or self is simply a “bundle” of perceptions; he thinks that “the essence of the mind [is] unknown to us.” Hume does not deny the existence of subjects of experience; he does not endorse a “no self” or “no ownership” view. Hume does not claim that the (...) subject of experience is not encountered in experience. The paper also examines Hume’s phenomenological account of self-experience—of what he comes across when he engages in mental self-examination by “entering intimately into what I call myself”—and his psychological account of how we come to believe in the existence of a persisting self as a result of the mind’s “sliding easily” along certain series of perceptions.

A spate of social scientific literature gives the impression that societies in the twenty-first century are overrun with ‘neoliberal subjects’. But what does it actually mean to be a neoliberal subject? And in what ways does this concept relate to ‘neoliberalism’, more generally? In this article, I distinguish between four common ways of thinking about ‘neoliberalism’: as a set of economic policies, as a hegemonic ideological project, as a political rationality and form of governmentality and as a specific type of (...) embodied subjectivity. I argue that while neoliberalisms, and potentially hold clear conceptual connections to one another – notwithstanding the quite real tensions between them – their relationship to neoliberalism is often tenuous at best. That is, the evidence routinely offered to demonstrate the existence of neoliberalism bears almost no necessary relationship to neoliberalisms, or. I conclude that, for both academic and political reasons, scholars should be more careful when invoking the monolithic notion of a ‘neoliberal subject’. (shrink)

As a result of this case study, additional questions arise. These can be cast into at least three groups. The first concerns the development of critical empiricism in the ancient world: a topic of much interest in our own century, expecially with regard to the work of the logical empiricists. Many of the same arguments are present in the ancient world and were hotly debated from the Hippocratic writers through and beyond Galen. Some of the ways in which (...) Galen reacts to Hippocratic and Aristotelian influences may, in part, be explained by Galen's own posture as a so-called Dogmatist. Both the Empirics and the Methodists offered alternative viewpoints on the place, role, and limits of observation in biomedical research. Though I have written on this relationship in the Hippocratic writers and Aristotle,44 it remains to be discussed in detailed fashion just how critical empiricism acted in Galen's evaluation of biomedical problems (aporiai). Contrasts between Galen and his predecessors might further clarify this issue both as a historical question and as it affects the construction of biological theory.The second area explores the question of how one develops comprehensive theories. In this respect Galen follows Aristotle's methodology rather closely. Both look at what theories are available to them and then systematically review the problems raised, at the same time refuting what they find inadequate. This is an effective strategy, for it permits utilizing the best features of earlier work to fashion a new whole. Indeed, Galen himself seems to attribute his use of such a methodology to his “ecletic” medical and philosophical training. Both Aristotle and Galen endeavor to employ techniques of theory integration. That is, they use aspects of theories they have already espoused to deal with new problems. This suggests the emergence of formal, logical coherence as an element in theory evaluation. The obvious drawback is that it can cause mistakes in one area to be repeated and ingrained in other areas. Such errors, because they are at the very core of an explanatory framework, may take centuries to correct. Future studies may shed light on how theory integration acts both in a positive and in a negative way.Finally, this case study offers a glimpse of how science progresses. Even though the advances in medical technology were comparatively minor, there is a great deal more sophistication in the conception theoreis of Aristotle and Galen than was present in the Hippocratic writers. Some of this (in Galen's case) had to do with increased anatomic and physiological knowledge, but most, I believe, is due to the evolution of scientific knowledge. If further work were done specifically on this question, it might document more completely how scientific knowledge on a specific topic evolves. The mode of advancement is primarily through gradual refinement of the types of questions being asked by these ancient authors, and the ramifications of their answers.Ancient theories of conception offer a fine case study in the history and philosophy of how a theory begins the develops. I have tried to suggest some interrelationships among the more important theories, as they focused upon Aristotle's own conception theory. There has been renewed interest in such cases in recent years. It is my hope that future specialized studies will increase our knowledge of method and practice in these important case studies and thereby augment our understanding of the genesis and application of biological theories.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:A Philosophical Path for Paracelsian Medicine: The Ideas, Intellectual Context, and Influence of Petrus Severinus (1540–1602)Dane T. DanielJole Shackelford. A Philosophical Path for Paracelsian Medicine: The Ideas, Intellectual Context, and Influence of Petrus Severinus (1540–1602). Copenhagen: Museum Tusculanum Press, 2004. Pp. 519. Cloth, $83.00.The Paracelsian and Danish royal physician Petrus Severinus complained, "If we can make more potent [drugs], extracted from metals and minerals,... I ask, what age (...) except this one will oppose our efforts?" (115). Indeed, early modern attempts to prepare and prescribe drugs forged in the alchemical laboratory often faced vehement opposition by the university-trained physicians who were weaned on the humoral theory and herbal materia medica of Galen. The orthodox Galenists disdained not only the "chemical poisons" of the Paracelsians, but also their theoretical speculations. After all, the Paracelsians dismissed the belief that disease was the result of humoral imbalances, and promoted both the analogy of microcosm (the human) and macrocosm (the natural world, including the stars), and the idea that diseases were essences or actual beings.Severinus was prescient in his prediction that chemical medicine would become popular, but—as Jole Shackelford notes in the introduction to his A Philosophical Path for Paracelsian Medicine—the concepts of Paracelsus and his followers continue to remain peripheral to the grand narratives of early modern intellectual history. This remains the case despite the illuminating studies of such scholars as the late-Enlightenment medical historian Kurt Polycarp Sprengel, Walter Pagel, and Allen Debus. Thus, Shackelford sheds much needed light on this significant strand of sixteenth- and seventeenth-century science and medicine. Via text-oriented study, particularly of Severinus's Idea medicinæ philosophicæ (Ideal of Philosophical Medicine), Shackelford provides a long-awaited and meticulous biographical account of Severinus and explains with refreshing clarity the sources and speculative theory behind his brand of chemical medicine. Like such recent scholars as Michael Walton and Charles Gunnoe, Shackelford presents Paracelsianism as an ideology, duly noting that the ideas of Severinus, reflecting the reception of Paracelsus in general, were frequently accepted or rejected on religious grounds.To begin, Shackelford establishes Severinus's importance, noting that the medical author and Wittenberg professor Daniel Sennert wrote in 1619 that most iatrochemists followed in the steps of Severinus, who had molded Paracelsus's ideas into a coherent philosophy. Shackelford then traces the story of how Severinus—after studying at such universities as Padua and Paris—joined his friend Pratensis (a recognized Paracelsian) and Tycho [End Page 488] Brahe in bringing an increasingly eclectic Denmark up to continental cultural and intellectual standards. Unfortunately, Severinus's appointment as physician to the king distracted him from completing most of his research projects, but he had already left for posterity his Idea medicinæ, published in 1571.As Shackelford writes, the Idea medicinæ promoted Severinus's belief that Paracelsian medicine was not only an alternative to humoral medicine, but also promised to cope better with "new" fevers. Also, Severinus invested Paracelsianism with authority by emphasizing its ancient forebears and by arguing that Paracelsus was the latest in the line of prisca theologia—one of the few to "ascend to the inner chambers of the Mosaic mysteries" (57). In his amalgamation of Neoplatonism, the Hippocratic tradition, and Paracelsus, Severinus's featured doctrine was efficient causation, or "semina theory." Unlike Robert Boyle's inertial, material corpuscles and their active principles, Severinus's semina were "intrinsically formal and immaterial, and were logically and ontologically prior to matter" (17).
