Ancient Rabbinic Medical Concepts and Taxonomies

Although the rabbis were interested in human physiology, opportunities to study human anatomy were extremely limited for most of antiquity because of nearly universal taboos against autopsy and dissection, including vivisection of animals. As a result, rabbis and non-Jewish contemporaries shared a vague concept of internal human anatomy that often became the object of analogical reasoning or imagery inspired by broader cultural or exegetical ideas. Rabbinic medicine had only rudimentary concepts of disease, and many disease-related terms in the Talmud remain obscure to us. Although rabbinic sources often mention only a disease name or a few symptoms, at times there are more elaborate descriptions of symptoms, etiologies, prognoses, and therapies in the form of lists or taxonomic discourse.

One of the clearer issues, however, was the concept of mental disease or disability, as encapsulated in the rather brutal nomenclature of the shoteh (“fool”), which became a general term for someone with any kind of mental incapacity. This condition was particularly important for its legal and halakhic ramifications. Equally important—for its many halakhic implications regarding a person’s ability to fulfill legal obligations or to act as a reliable witness—was the condition named qordiaqos, which probably had both physical and psychological manifestations.
