"The Evolution of Modern Medicine "consists of a series of historic lectures delivered by William Osler at Yale University in 1913. In these lectures, of which exists only one in-print edition, the renowned physician and medical historian Osler chronicles the history of medical science from its most ancient origins to the rise of modern medicine, in which he played an important role.
There were certain sections which were obviously and demonstrably false which the author purported to be fact. It therefore made it impossible for me to feel educated on sections of which I had no knowledge, since I could no longer trust the author's veracity by his previous false statements on subjects upon which I did have knowledge. The author is also extremely anti-religious to the point of belligerent fanaticism, and so I would just encourage you to seek this knowledge elsewhere and from a less biased source.
The book "The evolution of Modern medicine" drives back to 10th century around how the medicine started getting evolved in the world and how each thesis added up to the current modern medicine. When we say medicine it doesn't mean the theories that are in scientific means. It means also how it evolved from astronomy, astrology and black magic. It gives good idea on people who are still the foundation for the modern medicine built such as galen, hippocrates, vaselius, fabricius and all. Had great insight on the advent and spread of medicine culture. Altogether Great read.
