The paper, as the title indicates, will be confined to a comparison and evaluation of Platonic love against love as articulated within Christianity. Both forms of love will be analyzed and I will attempt to show that although Plato, through Socrates （and Socrates through the Diotima character）, tries to redeem the traditional understanding of love in the ancient Greek society that he was living in, Platonic love is still very different from the Christian concept of love.展开更多
