A value system is very important for one’s behavior. A change of one’s value system means the change of one’s motivations and aspirations, perceptions and interpretations, meanings and satisfaction, and the revaluation of one’s criterion about existence and man. A value system acts as the primary factor in one’s attitudes and behaviors. One’s value system influences one’s existence and the development of the community. Especially, the value system of pure love is a core factor for the formation of a sense of what husbands and wives are. Since human sexuality is the root of human existence for the formation of the human community, the family community extends and continues into the social community. The human sexuality of pure love maintains public safety and order in the family and society. The purpose of this paper is to suggest the inclusion of the education of the value system of pure love in the sexuality education of the schools. This thesis presents the limitations of the absence of the education of the value system of pure love in the sexual education of the schools, and it emphasizes the significance of educating students in the value system of pure love. Moreover, this paper suggests educating students in the value system of pure love in the sexual education of the schools. This thesis discusses what kinds of roles in human life the value system of pure love has, and it explores how to apply it to human life and to the sexual education of the schools.
