Abstract: | The problem of ‘reality’ and ‘realism’ is rarely discussed in medieval medical texts, although medieval medicine is based on objectivity. There are three reasons why medieval physicians were so sure about their image of human nature: the convincing model of humoral pathology, the undoubted truth of tradition, and the suggestive similarities between worldly things and their presumed divine purpose. Thus, individual cases were only examples of the common theory of medicine and were by no means able to change it. |
