The word “epistemology” etymologically comes from two Greek words: epistēmē (knowledge) and logos (study) and is conventionally defined as “Theory of Knowledge.” Was first introduced by James F. Ferrier (1808–1864), English philosopher and based on thoughts of Georg Berkeley introduced the term epistemology, begins the development of his thought with the axiom: “Along with whatever any intelligence knows, it must, as the ground or condition of its knowledge, have some cognisance of itself.” And will conclude by stating: “All absolute existences are contingent except one; in other words, there is One, but only one, Absolute Existence, which is strictly necessary; and that existence is a supreme and infinite and everlasting Mind in synthesis with all things” [1].
