Birth of Scientific Medicine: What Happened
In the late 5th century BC, the physician Hippocrates of Kos and his followers laid the foundations of medicine as a science. Before this, illness was widely seen as a punishment or intervention from the gods. The Hippocratic doctors argued instead that diseases had natural causes that could be studied and treated. They carefully observed their patients, recorded symptoms, and tracked how illnesses developed, emphasizing diet, exercise, rest and a healthy environment. They believed health depended on a balance of four bodily fluids, a theory that was wrong but shaped medicine for more than two thousand years. Their teachings survive in a large collection of texts known as the Hippocratic Corpus, written by several authors over time rather than by Hippocrates alone. These works cover everything from fractures and epidemics to medical ethics. The most famous is the Hippocratic Oath, in which doctors pledged to act for the benefit of patients and do no harm. Versions of the oath are still recited by medical graduates today, and Hippocrates is widely known as the Father of Medicine.
