Based on Martha Nussbaum's "capacities approach theory" and "poetic justice" argument, this article analyzed the practical values of different public emotions, including love, compassionate, and anger, to demonstrate Nussbaum's attempt of developing a compassionate citizenship education foundation. In addition to the concepts developed in her earlier works, such as "Love's Knowledge: Essays on philosophy and literature", "Poetic justice: The literary, imagination and public life", "Upheavals of thought: the intelligence of emotions", or "Cultivating humanity: a classical defense of reform in liberal education", the viewpoints of her recent works "Political emotions: Why love matters for justice" and "Anger and forgiveness: Resentment, generosity, justice" are included in the discussion of this article as well. The purposes of this article are to firstly explain the argument of Nussbaum's social justice incorporating "emotional intelligence", and to analyze the metaphorical meaning of public emotion "between Scylla and Charybdis". Secondly, the article intended to expound Nussbaum's advocates of "poetic justice" and the educational value of her view "public emotions". Thirdly, this article discussed a different definition of public emotions and justice made by John Rawls, and put forward critics for Nussbaum made by some scholars. Finally, through examining the positive value of political emotions, this article would propose an education that is awakened by rich emotions and a way out for educational dilemmas and moral issues.
