Understanding epistemology and its key approaches in research

Abstract

Epistemology is a branch of philosophy that concerns itself with the theory of knowledge. It is regarded as a core area of philosophy because it deals with the nature of our knowledge. Drawing on the literature on epistemology, this article provides some basic definitions of the term epistemology and answers some key epistemological questions such as: “what is knowledge?” “what are the sources of our knowledge?” “what do we know?” and “what differentiates knowledge from wisdom and opinion?” The article also discusses key epistemological approaches, namely positivism, interpretivism, and pragmatism, which are central to research. The article concludes that a high degree of epistemic justification is required for knowledge claims and for the conduct of research.
