Introduction
Hippocratic medicine remains one of Ancient Greece's lasting contributions to the field of science. Lacking the equipment physicians today take for granted when diagnosing and healing their patients, Hippocratic physicians were forced to create a novel system for explaining and curing disease based upon the prevalent scientific theories of their era. This system became known as the humoral theory of disease. Humoral theory incorporated the theories of Presocratic philosophers in order to explain disease and offer help for a cure. Two themes characterizing Presocratic philosophical thought dramatically influenced humoral theory. The humoral theory approach of Hippocratic medicine was based upon Presocratic philosophical musings about the relationship of man to the world. By the time humoral theory was vogue, philosophers had concluded that both man and the world were governed by the same natural laws. Humoral theory also was based upon Presocratic theories about change and how it occurred in the world; humoral theory depended upon the assertion that contrasting elements constantly contradicted each other, leading to continuous change on one level and stability on another. These two Presocratic theories shaped humoral theory and allowed the physician to develop a rational and empirically based approach to medicine.

Most of what is known about the historical figure Hippocrates, the supposed founder of the Hippocratic medical approach, must be evaluated with caution. Hippocrates lived c. 460-370 BC, but further reliable information about his life is difficult to obtai ...
