epistemology

Etymology

It is formed from English epistemo- + -logy,^[2][3][4] the first element being the combining form of Ancient Greek ἐπιστήμη (epistḗmē, “knowledge, understanding”),^[5][6][7][8] from ἐπίσταμαι (epístamai, “to know, know how to do, understand”),^[7][9][3] itself from ἐπί (epí, “upon, over”) and ἵσταμαι (hístamai, “to stand”),^[7][9][8] from Proto-Indo-European *stā- (“to stand”).^[9][8] Etymonline glosses the Greek verb literally as "overstand", and Klein compares the sense development of understand.^[9][7] The OED models the English word on German Wissenschaftslehre, used from 1793 in the titles of several works by J. G. Fichte.^[5] Etymonline, Barnhart and Klein credit the coinage to the Scottish philosopher James Frederick Ferrier, Klein in his “Institutes of Metaphysics” of 1854;^[9][7][3] the OED, revised in 2014, has an earlier record of 1847.^[5]

Earliest recorded meaning

The theory of knowledge and understanding, its methods, validity and scope: 1847, in the Eclectic Magazine.^[5][10] Etymonline, Barnhart and Merriam-Webster Unabridged date the word to 1856, and Klein to Ferrier's book of 1854.^[9][3][2][7]

Semantic evolution

The word has kept its philosophical sense, the branch of philosophy that deals with the grounds and validity of knowledge.^[6][5][11] The adjective epistemological followed in the late 19th century,^[6] and epistemics, the scientific rather than philosophical study of knowledge, in 1969.^[9]
