ABSTRACT: This philosophical essay explores the epistemological foundations of knowledge organization and discusses im- plications for classification research. The study defines the concept of “knowledge,” distinguishes between subjective knowl- edge (i.e., knowledge as a thought in the individual’s mind) and objective knowledge (i.e., knowledge as an independent ob- ject), establishes the necessity of knowledge organization in the construction of knowledge and its key role in the creation, learning, and dissemination of knowledge, and concludes with implications for the development of classification schemes and knowledge maps. Overview second stage, I will discuss the relationship between subjective knowledge and objective knowledge.
