"Still more harm is caused by the extreme specialization of the physicians. Medicine has separated the sick human being into small fragments and each fragment has its specialist. When a specialist, from the beginning of his career, confines himself to a minute part of the body, his knowledge of the rest is so rudimentary that he is incapable of thoroughly understanding even that part in which he specializes. A similar thing happens to educators, clergymen, economists, and sociologists who, before limiting themselves entirely to their particular domain, have not taken the trouble to acquire a general knowledge of man. The more eminent the specialist, the more dangerous he is."
