The purpose of this paper is to investigate the happiness and education principles of St. Augustine and Mozi through the primary and the secondary language resources. To review the paper logically, three research questions are addressed. First, what are the happiness principles of Augustine and Mozi? Second, what are the educational principles of Augustine and Mozi? Third, what are significant similarities and differences between the two sages? In order to defend the research questions, a descriptive content analysis method will be used with a culturally comparative approach. As for the limitations of the paper, the principle of education is mainly discussed from a viewpoint of educational philosophy. The principle of happiness is also reviewed in terms of moral and political theories. This academic paper is mainly focused on "The Canon of Mozi," on "The City of God," and "On Christian Teaching" of St. Augustine. The author in the paper intends to utilize modern English second resources as well as the classical Chinese and Latin primary languages. Finally, the author concludes this position paper with the suggestion of future research. The significance of the study is to provide the basic theories and the valuable resources of contemporary and future education, especially happiness, moral, religion, pragmatic, or multicultural education, for educational theorists and practitioners in the world in the aspect of the mutual understanding of the Eastern and the Western cultures.
