Someone who has thought rationally and deeply about how the body works is likely to arrive at better ideas about how to be healthy than someone who has followed a hunch. Medicine presupposes a hierarchy between the confusion the layperson will be in about what is wrong with him, and the more accurate knowledge available to doctors reasoning logically.
