Epistemology
The word "epistemology" is derived from the ancient Greek "epistēmē" meaning "knowledge" and the suffix "-logy", meaning "logical discourse" (derived from the Greek word "logos" meaning "discourse"). It is analogue to the German "Wissenschaftslehre" (literally, theory of science) which was introduced by philosophers Johann Fichte and Bernard Bolzano in the late 18th century. The word first appeared in English in 1847 as a translation of the German in New York's "Eclectic Magazine" review of a philosophical novel by German author Jean Paul:
Eclectic medicine
The term was coined by Constantine Samuel Rafinesque (1784–1841), a botanist and Transylvania University professor who had studied Native American use of medicinal plants, wrote and lectured extensively on herbal medicine, and advised patients and sold remedies by mail. Rafinesque used the word "eclectic" to refer to those physicians who employed whatever was found to be beneficial to their patients (eclectic being derived from the Greek word "eklego", meaning "to choose from").
