Scientific Revolution

The Scientific Revolution abandoned medicine based on the Greek idea of the four humors and made important discoveries regarding the humans body that led to a new theory of medicine.  It suggested materialist, non-religious explanations for disease based on observation and experimentation.  Some new medicines were discovered and employed, for example quinine.  New initiatives in public health such as the keeping of vital statistics and government-run “poor houses” and hospitals were undertaken.  What evidence is there that the health conditions of ordinary people did not change much as a result and why do you think that?
