This study reveals the conceptualization of ‘education’ in Lee Hongwoo’s theory of
knowledge-education and critically investigates it. For this purpose, this study reveals the
conceptualization of ‘education’ in Lee Hongwoo’s theory of knowledge-education such as
functional-based conceptualization, institutional conceptualization, conceptualization by syncretism and
juxtaposition, and discusses its limitations. First, it is discussed that Lee Hongwoo’s theory of
knowledge-education conceptualizes ‘education’ by functional conceptualization on the perspective of
science in its own context. And the limitations that the boundaries between ‘education’ and science
became unclear, that academic value is defined as an intrinsic value of ‘education', that there is no
fair discussion of the external value of education, and that there is a distortion of the task of the
study of education and the educationalist are discussed. Second, it is discussed that Lee Hongwoo's
theory of knowledge-education shows a form of institutional conceptualization of ‘education’, and
the conceptual universality of education as an aspect of human life is not fully satisfied respectively.
Thirdly, it is discussed that Lee Hongwoo’s theory of knowledge-education follows the method of
conceptualizing ‘education’ in a way that blends and juxtaposes the other branches of Psychology,
Philosophy, and disciplines. And it is also discussed that it is causing the dependence on other
disciplines along with the confusion of the educational context and raising the possibility of
voluntary reduction of study of education to other academic disciplines.
