Although scholars acknowledged that Avicenna’s science of the soul stands at the crossroads between natural philosophy and metaphysics, thus combining an overall physical investigation of all sublunary souls with a trans-physical (or proto-metaphysical) inquiry into the human rational soul, this paper aims to show a further disciplinary entanglement within Avicenna’s science of the soul, which features in the aforementioned physical investigation and helps to frame it, that is, the interaction between natural philosophy and medicine. Despite the strict division between these (...) two disciplines in Avicenna’s system of science, medicine seems to decisively contribute to accounting for the bodily functions of living beings. For this reason, Avicenna refers to medicine several times in his exposition on the soul. This paper approaches the disciplinary entanglement between natural philosophy and medicine in psychology by focusing on the medical concept of pneuma (rūḥ), which prominently features in the exposition of three main issues in psychology, i.e., body ensoulment, powers differentiation, and emotions.

During the Middle Ages, physicians, philosophers, and theologians developed a complex and rich discourse on the concept of sickness. Illness (infirmitas) was perceived as the natural state of existential imperfection for homo viator, fallen due to sin and impaired in his bodily integrity. Leprosy, smallpox, plague and the other collective diseases that constantly plagued medieval societies prompted reflections on etiology and modes of transmission of epidemics. Building on Galenic teachings, medieval medicine – both Arabic and Latin – delved into the (...) study of fevers. Key concepts in medical pathology, such as the humors, humidum radicale, and spiritus, were assimilated and reinterpreted within philosophical and theological frameworks. The ten contribution collected in this volume explore this rich array of concepts and themes by closely examining the theories and works of prominent and lesser-known figures in medicine, theology, and philosophy active across Latin Christendom, the Islamic context, and the Jewish world: from Augustine to ʿAlī ibn al-ʿAbbas al-Maǧūsī, from Avicenna to Constantine the African, from Maimonides to Albert the Great, from Arnau de Vilanova to Gentile da Foligno, from Henry of Herford to Michele Savonarola.

The first part of the essay examines the different premises, of Aristotelian and Galenic origin, for the idea of an inherent consumption of the natural heat of every living body, discussing the contributions of Isaac Israeli, Avicenna and Averroes to the reflection on the relationship between the secondary humours (or moistures) and the peculiar category of fevers called ‘hectic’. The second part of the article discusses how the link between moisture, heat and food was taken up and elaborated by Latin (...) Scholastic masters (in particular Thomas Aquinas), and considers the use of the notion of ‘radical moisture’ in the field of theology. Aquinas does not follow the previous theological tradition, originating with Peter Lombard, which denies the possibility that the matter assimilated through food is part of the bodily core that belongs to every human being from birth. The moisture provided by food is, in fact, inseparable from the (radical) moisture that originally belongs to each individual; as such, it is part of the ‘truth of human nature’ (veritas humanae naturae) that will be restored at the moment of the resurrection of the body.

This is the first French translation of Galen’s De optima doctrina, which articulates his view “On the Best Teaching”. The translation is preceded by an introduction on the context in which this text was written, especially on the relationship of Galen towards scepticism in general and Favorinus of Arles in particular. Although it is hard to characterize this “treatise” in terms of its date of redaction and its form, nonetheless it yields clear information on Galen’s critiques with regards to the (...) “Platonists” and the “Pyrrhonists”.

This volume explores the versatility of the concept of pneuma in philosophical and medical theories in the wake of Aristotle’s physics. It offers fourteen separate studies of how the concept of pneuma was used in a range of physical, physiological, psychological, cosmological and ethical inquiries. The focus is on individual thinkers or traditions and the specific questions they sought to address, including early Peripatetic sources, the Stoics, the major Hellenistic medical traditions, Galen, as well as Proclus in Late Antiquity and (...) John Zacharias Aktouarios in the early 14th century. Building on new scholarly approaches and on recent advancements in our understanding of Graeco-Roman philosophy and medicine, the volume prompts a profound re-evaluation of this fluid and adaptable, but crucially important, substance, in antiquity and beyond.

The Pneumatist school of medicine has the distinction of being the only medical school in antiquity named for a belief in a part of a human being. Unlike the Herophileans or the Asclepiadeans, their name does not pick out the founder of the school. Unlike the Dogmatists, Empiricists, or Methodists, their name does not pick out a specific approach to medicine. Instead, the name picks out a belief: the fact that pneuma is of paramount importance, both for explaining health and (...) disease, and for determining treatments for the healthy and sick. In this paper, we re-examine what our sources say about the pneuma of the Pneumatists in order to understand what these physicians thought it was and how it shaped their views on physiology, diagnosis and treatment.

In late Renaissance medicine, the example of digestion was frequently invoked to prove the elemental composition of the human body. Food was considered as being decomposed in its first elements by the stomach, and digested into a thick juice, which was assimilated by the liver and the body parts. Such a process points to the structure of the human body into four elements that are transformed into different types of humors during several stages of “concoction”. This chapter examines the Galenic (...) interpretation of digestion expounded by the French physician Jean Fernel (1497–1558) in his Physiologia (1567). In this treatise, Fernel states the body composition into elemental portions, while stressing the role of the “innate heat” as the physiological counterpart of the body’s essence or “substantial form”. He applies this view in his account of digestion, where he states that the conversion of food follows the rule of “mixture”. This chapter aims to explore how Fernel applies his interpretation of elements and innate heat to the process of digestion, as well as his sources in Galen’s De facultatibus naturalibus, Avicenna’s Canon and Aristotle’s Meteorologica. It first examines the role of the natural soul and its “nourishing” faculties in nutrition as a physiological function. It then considers the role of elements, humors and innate heat during the “concoction” of food in the stomach, liver and veins. (shrink)

Athenaeus of Attalia distinguishes two types of exercise or training (γυμνασία) that are required at each stage of life: training of the body and training of the soul. He says that training of the body includes activities like physical exercises, eating, drinking, bathing and sleep. Training of the soul, on the other hand, consists of thinking, education, and emotional regulation (in other words, 'philosophy'). The notion of 'training of the soul' and the contrast between 'bodily' and 'psychic' exercise is common (...) in the Academic and Stoic traditions Athenaeus is drawing from; however, he is the earliest extant medical author to distinguish these kinds of training and to treat them as equally important aspects of regimen. In this paper, I propose some reasons why he found this distinction useful, and I examine how he justified incorporating it into his writings on regimen, namely by attributing Plato's beliefs about regimen to Hippocrates, a strategy Galen would adopt well over a century later.

ABSTRACT: Galen’s Institutio Logica is the only introduction to logic in Greek that has survived from antiquity. In it we find a theory that bears some resemblance to propositional logic. The theory is commonly understood as being essentially Stoic. However, this understanding of the text leaves us with a large number of inconsistencies and oddities. In this paper I offer an comprehensive alternative interpretation of the theory. I suggest that it is Peripatetic at base, and has drawn on Stoic elements, (...) but adapted them to an overall decidedly non-Stoic conception of logic and language, a conception indebted to Aristotelian logic in many respects. This interpretation makes it possible to reduce the seeming inconsistencies dramatically. The Peripatetic theory on which Galen draws was possibly developed in the first century BCE. Importantly, it differs from Stoic logic in that it shuns the latter’s syntactic approach, and considers certain linguistic assumptions and language conventions as part of the logical theory itself. My reconstruction of the theory results in a logic of propositions which differs wildly both from Stoic logic and from the ‘classical’ propositional logic of the 20th century. Interestingly, though, the theory in Galen shows that the ancients grappled with a number of logico-linguistic problems that over the last two decades have again become a matter of debate among contemporary logicians and linguists.

This article explores Galen's analysis of and response to the Rationalist and Empiricist medical sects. It argues that his interest in their debate concerning the epistemology of medicine and anatomy was key to his advancement of an experimental methodology.

The Predynastic Period in Ancient Egypt is the time before recorded history from the Paleolithic to the Neolithic Age and on to the rise of the First Dynasty and is generally recognized as spanning the era from c. 6000-3150 BCE (though physical evidence argues for a longer history). While there are no written records from this period, archaeological excavations throughout Egypt have uncovered artifacts which tell their own story of the development of culture in the Nile River Valley. The periods (...) of the Predynastic Period are named for the regions/ancient city sites in which these artifacts were found and do not reflect the names of the cultures who actually lived in those areas. The Predynastic Period was given its name in the early days of archaeological expeditions in Egypt before many of the most important finds were discovered and catalogued which has led some scholars to argue over when, precisely, the Predynastic Period begins and, more importantly, ends. These scholars suggest the adoption of another designation, 'Protodynastic Period', for that span of time closer to the Early Dynastic Period (c. 3150-2613 BCE) or 'Zero. (shrink)
