Protagoras' opening is not just the prologue of the main content of this book but also the prologue of Socrates' political philosophy career.Taking the educational dialogues between Socrates and Hippocrates as a sample, the article analyzes the educational implication of Socratic dialogues through close reading. In Socratic education, the starting point is the careful reflection on individual's self-mind and the limit, as well as the establishment of spiritual connection of teacher-student relationship. The specific path of education is the realization of individual self-awareness through dialectical dialogues, and leisure is a prerequisite for education to happen. As a model teacher, Socrates' typical significance lies not only in his superb educational skills, but also his love for the polis and its youth.
