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:
Peripatetic school
The term "Peripatetic" is a transliteration of the ancient Greek word "περιπατητικός" ("peripatêtikos"), which means "of walking" or "given to walking about". The Peripatetic school, founded by Aristotle, was actually known simply as the "Peripatos". Aristotle's school came to be so named because of the "peripatoi" ("colonnades" or "covered walkways") of the Lyceum where the members met. The legend that the name came from Aristotle's alleged habit of walking while lecturing may have started with Hermippus of Smyrna.
