The theory of medicine, therefore, presents what is useful in thought, but does not indicate how it is to be applied in practice-the mode of operation of these principles. The theory, when mastered, gives us a certain kind of knowledge. Thus we say, for example, there are three forms of fevers and nine constitutions. The practice of medicine is not the work which the physician carries out, but is that branch of medical knowledge which, when acquired, enables one to form an opinion upon which to base the proper plan of treatment.
Avicenna

The fact that the patients were complex human beings with a rich life beyond the hospital never really sank into the consciousness of the residents. Because they had no rich lives beyond the hospital, they assumed no one else did, either. In the end, what they lacked was not medical knowledge but ordinary life experience.
Michael Crichton
