Scholars looking back to the earliest stirrings of the philosophical tradition in ancient Greece have often seen a rational approach to nature cleaving itself off from an older approach, that of the mythographer. If this account were right, we would have here a major (and perhaps the ?rst major) drawing of an epistemic boundary. There are, however, mounting reasons to question this narrative that have been accumulating across several modern disciplines. This paper explores the most important challenges to the myth-to-science (...) narrative and suggests that the different ways of framing the ancient debates have much to do with the boundaries between modern disciplines and/or academic cultures.

ArgumentAt the end of the seventeenth and beginning of the eighteenth century, ageing was specifically a medical issue. Indeed, on the one hand, ageing is a normal process of living; on the other hand, old age often entails specific pathologies. Is it really possible to dissociate old age from pathology? If so, how can we think of old age and explain both the necessity and the normality of it? If not, what is the cause of this dysfunction? Modern medical controversies (...) argue along the lines of the respective partisans ofiatromecanism, empirical medicine, and animist medicine. Furthermore, it progressively appears that the issue of aging must also be addressed within the social field, where old age is affected by sanitary, economic, and strategic conditions. Indeed, doctors, economists, and philosophers even tried to assess old age quantitatively with new methods of arithmetic. Thus, in this paper, we want to draw what constitutes the systems of knowledge of old age as a medical category located at the borderlines between epistemological, practical, and social challenges.

This paper deals with the two notions of aition or aitia and prophasis in the Greek medical texts and asks the question of whether these words are synonymous or not. Therefore, it explores their different meanings in different contexts both in the Hippocratic and in the Galenic corpus. It also investigates how Galen understands these two notions when he reads them in the Hippocratic treatises and how he explains them in his commentaries to Hippocrates, and in particular, if he gives (...) the same meaning to these words in his own treatises or if he uses them in a different way.

Humoralism, the view that the human body is composed of a limited number of elementary fluids, is one of the most characteristic aspects of ancient medicine. The psychological dimension of humoral theory in the ancient world has thus far received a relatively small amount of scholarly attention. Medical psychology in the ancient world can only be correctly understood by relating it to psychological thought in other fields, such as ethics and rhetoric. The concept that ties these various domains together is (...) character (êthos), which involves a view of human beings focused on clearly distinguishable psychological types that can be recognized on the basis of external signs. Psychological ideas based on humoral theory remained influential well into the early modern period. Yet, in 17th-century medicine and philosophy, humoral physiology and psychology started to lose ground to other theoretical perspectives on the mind and its relation to the body. This decline of humoralist medical psychology can be related to a broader reorientation of psychological thought in which the traditional concept of character lost its central position. Instead of the focus on types and stable character traits, a perspective emerged that was primarily concerned with individuality and transient passions. (shrink)

Galen's stories about his successes in predicting the development of an illness belong to the best-known anecdotes drawn from his writings. Brilliant pieces of self-presentation, they set Galen apart from his peers, who tried to cover up their ignorance by levelling accusations of magic and divination against their superior colleague. These accusations are usually interpreted as very real threats, as Roman law punished illicit magic and divination. Pointing out that Galen sometimes likes to present himself as amantisand a prophet, others (...) have suggested that the accusations against Galen and his own self-presentation indicate that the border line between medicine and religion was still fluid. Both approaches correctly draw attention to the social reality that the accusations betray: they suggest that Galen belongs to a group of healers of dubious standing that populated the empire and thus show that medicine did not have a monopoly on healing. Yet such a socio-historical approach may not be sufficient. For one thing, both explanations have their limitations. Regarding the former, it can be said that Augustus' prohibition of divination aimed at controlling prediction about the emperor and one can doubt that a widespread clampdown of all forms of divination ever was intended. A possible objection to the second view is that throughout hisoeuvreGalen emphasizes his medicine as a rational undertaking, even as a science (epistêmê). If one takes his self-presentation as amantisto be more than metaphorical and to indicate the not yet fully crystallized identity of medicine as a separate scientific discipline, then Galen's usual way of understanding his own craft as a ‘science’ is in need of explanation. Besides such possible objections, a different set of questions still needs to be asked: why precisely were accusations of practising magic and divination levelled against Galen and why do they recur so frequently in his writings? Why divination and not, say, poisoning? (shrink)

The author deals with the lost works of Empedocles, an often neglected subject, in the frame of the discussion concerning the number of the poems and their main features. He reviews the traces of the Passage of Xerxes, of the Medical Discourse, and of the Proem to Apollo among the fragments and witnesses, taking his cue from textual aspects and dealing with the contents, the significance of each of these writings in Empedocles’ culture and thought and their multifarious relationships with (...) his times. As to the Passage, he tries to reconcile the contrasting interpretations so far proposed (historical or religious poem). Concerning B111, the only relic from the Medical Discourse, he explains why its contents are incompatible with the Physical Poem and the Purifications. He analyzes the Proem to Apollo in several perspectives (text, witnesses, contents also from the epistemological point of view, literary genre). He assigns fragments 131–134 and 142 to the Proem, drawing one of his arguments from the comparison with the third Homeric Hymn to Apollo, and also suggesting a relationship with an intellectual cult of the sun. Formal features help to ascribe each fragment to the relevant poem. Close similarities between fragments do not necessarily mean that they come from the same writing: Empedocles is wont to allude to one poem of his while composing another. The author concludes that the striving for a reductio ad unum of the Acragantine’s output, also evident in the attempt by a number of scholars to make only one poem out of the Περὶ φύσεως and the Καθαρμοί, has often led researchers to take for granted that none of the fragments preserved might belong to the lost works.

Alcmaeon, a philosopher-cum-doctor from Croton, offers the earliest known definition of health and disease. The aim of this paper is to examine the formulation of his medical theory in terms of political organization, namely the polarity between one-man rule and egalitarianism , by taking into account contemporary philosophical and medical texts, as well as the historical context. The paper is divided into four sections. I first overview the compendium in which this medical theory is reported, trace the doxographical layers, and (...) analyse the terminology employed . I then focus on the key aspects of this medical theory, including the constitution of the body, the interaction of opposites, and the aetiology of disease . I suggest that Alcmaeon's notion of equality can be understood in various ways, and discuss the possible interpretations in the light of early Greek philosophy and medicine. The most likely interpretations are that there exists a kind of equilibrium between pairs .. (shrink)

In his accounts of plant and animal generation Pierre Gassendi offers a mechanist story of how organisms create offspring to whom they pass on their traits. Development of the new organism is directed by a material “soul” or animula bearing ontogenetic information. Where reproduction is sexual, two sets of material semina and corresponding animulae meet and jointly determine the division, differentiation, and development of matter in the new organism. The determination of inherited traits requires a means of combining or choosing (...) among each parent's contributions, and towards this end, Gassendi outlines the nature of competition and dominance among animulae. Unlike his fellow mechanists, Gassendi can extend his mechanism to his heredity account, because his proposed vehicle for ontogenetic transmission is material. That proposal in turn relies on his atomist hypothesis. The relative uniformity of atoms allows animulae to operate equivalently across different modes of generation, spontaneous or otherwise. Further, his molecular model of atomic structures allows a material means of storing ontogenetic information received from the souls of parent organisms. These accounts—flawed and sketchy—unsurprisingly fail to specify how hereditary information might be borne physically, and in any case do not meet Gassendi's own empiricist standards. Yet this generation theory with pretensions to a materialist mechanism establishes Gassendi's firm commitment to a unity of the sciences through an atomist ontology that underlies all physical phenomena, including the organic.

In Sophistical Refutations 8 Aristotle claims that every sophistical refutation depends on a false belief which is implicitly held by the victim of the fallacy and can normally be elicited from him as an explicit additional premiss. In this case the fallacious argument will be turned into a valid one, albeit with a false premiss. The paper discusses the nature of the FVP and tries to discover how it works when it tacitly causes the false appearance of a fallacious argument.

This article considers the prospects of inference to the best explanation as a method of confirming causal claims vis-à-vis the medical evidence of mechanisms. I show that IBE is actually descriptive of how scientists reason when choosing among hypotheses, that it is amenable to the balance/weight distinction, a pivotal pair of concepts in the philosophy of evidence, and that it can do justice to interesting features of the interplay between mechanistic and population level assessments.

Although there is consensus on the fact that ionizing radiation used in radiological examinations can affect health, the stochastic nature of risk makes it difficult to anticipate and assess specific health implications for patients. The issue of radiation protection is peculiar as any dosage received in life is cumulative, the sensitivity to radiation is highly variable from one person to another, and between 20 % and 50 % of radiological examinations appear not to be necessary. In this context, one might (...) reasonably assume that information and patient consent would play an important role in regulating radiological practice. However, there is to date no clear consensus regarding the nature and content of—or even need for—consent by patients exposed to ionizing radiation. While law and ethics support the same principles for respecting the dignity of the person, in the context of radiology practice, they do not provide a consistent message to guide clinical decision-making. This article analyzes the issue of healthcare professionals’ duty to inform and obtain patient consent for radiological examinations. Considering that both law and ethics have as one of their aims to protect vulnerable populations, it is important that they begin to give greater attention to issues raised by the use of ionizing radiation in medicine. While the situation in Canada serves as a backdrop for a reflective analysis of the problem, the conclusions are pertinent for professional practice in other jurisdictions because the principles underlying health law and jurisprudence are fairly general.
