In terminology, epistemology (TR:33), from the Greek episteme (knowledge) + -logy (doctrine; theory; science), is the study or a theory of the nature and grounds of knowledge especially with reference to its limits and validity. [1]
In 1854, Scottish German-idealism philosopher James Ferrier (1808-1864) coined the term “epistemology”, referring, supposedly, to the study of knowledge, in explicit contrast to the common-sense tradition of how one knows about something. (Ѻ)
