One of the challenges in substantiating deliberative democracy as a normative theory is the educational challenge of how to cultivate civic virtue, especially mutual respect and civility, in children. The cultivation of civic virtue is not limited to school education, but is also an activity related to family education. However, liberal theorists who advocate the theory of deliberative democracy, based on the dualism of public and private, have limited their discussions to the issue of civic development in the field of public education. This article proposes to understand and compare the many competing theories on public-private dualism, particularly in liberal and feminist spaces. Beginning with an analysis of the work of liberal theorists such as David Archard as well as Harry Brighouse and Adam Swift, and moving on to that of feminist theorists such as Susan Okin, this article examines competing theories on education in school and in the family, to whom the responsibility of education belongs, and where feminist and liberal thought enlighten these debates. This article will clarify the theoretical tendencies and principles of liberal arguments aimed at overcoming the public-private dualism in education, and present a strategy for overcoming the challenges that this theory encompasses by seeking reference points in feminist thought, especially with attention to conception of relational autonomy.
