The contribution aims to analyze the pathology of leprosy (al-ǧuḏām) and smallpox (al-ǧudarī) in the Arabic medical encyclopedia Kitāb al-Malakī, composed by the physician ʿAlī ibn al-ʿAbbas al-Maǧūsī, and in its two Latin translations, the Pantegni by Constantine the African and the Liber Regalis by Stephen of Antioch. The study of the Arabic text shows that the etiology of these diseases involves an interplay of different factors, including contagion, and explains to what extent the Kitāb al-Malakī presents original doctrines. (...) Secondly, by taking into account similarities and shifts in comparison with the Arabic original, the contribution shows how the two Latin translators faced the challenge of creating a new lexicon as a vehicle for the innovative translated ideas.

Why scientists reach an agreement on new experimental methods when there are conflicts of interest about the evidence they yield? I argue that debiasing methods play a crucial role in this consensus, providing a warrant about the impartiality of the outcome regarding the preferences of different parties involved in the experiment. From a contractarian perspective, I contend that an epistemic pre-requisite for scientists to agree on an experimental method is that this latter is neutral regarding their competing interests. I present (...) two medical experiments (on smallpox inoculation and Mesmerism) in which debiasing procedures such as blinding and data tabulation provided warrants of impartiality that made people agree on the experimental design even if they disagreed on the outcome.

Kant and Medicine - the Philosopher as Anthropologist, Physician and Patient. It remains uncertain whether the student Immanuel Kant (1724-1804) truly wanted to become a physician or only said this in order to please a sponsor. Due to his narrow chest and other typical weaknesses of a scholar he considered himself a hypochondriac and cautiously kept his distance from dangerous illnesses, especially those of the mind. He inspired his students - including Herder, Herz, Lenz and Hoffmann - far less with (...) logic and metaphysics than with exciting findings about far away countries, their alien inhabitants and the health dangers lurking in exotic parts of the world. He called for philosophical treatment of physical illnesses beyond the limited "veterinary" approach of medicine. He claimed the responsibility of the philosophy faculty for forensic questions. Kant developed original ideas about the seat of the soul, which led to the construction of a first model of the brain including functioning synapses. He was unable to overcome reservations about smallpox vaccination because he feared a change in the germ line. He wanted to see "how long the stuff would last" and during his later decades used all the classic dietetics to successfully extend his life. These sex res non-naturales continue to play a significant role in the prevention of widespread diseases today. Then an "electric revolution of the air strata" took its toll on him. Towards the end, his confidants were to look at him like a child, who, however, left posterity an extensive work with deep insights into his thinking, the Opus postumum. (shrink)

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.
