Homϗpathy, and its kindred delusions; Two lectures delivered before the Boston Society for the Diffusion of Useful Knowledge, Oliver Wendell Holmes, Boston, 1842
A faculty member at Harvard Medical School from 1847 to 1882, physician and poet Oliver Wendell Holmes (1809-1894) had no patience with homeopathy, the leading mid-century sectarian challenge to "regular" medicine. He thought that homeopathy, derived from the late 18th-century writings of German physician Samuel Hahnemann, whose practitioners believed a disease could be cured by a substance that produces symptoms similar to the disease in healthy people, represented a backwards-sliding regression in medicine, not an advance of any sort in either theory or therapy.
