"Episteme" is a philosophical term derived from the Ancient Greek word ἐπιστήμη "epistēmē", which can refer to knowledge, science or understanding, and which comes from the verb , meaning "to know, to understand, or to be acquainted with".
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.
