Erōs is passionate love. In the Symposium, Diotima teaches Socrates that love is the desire to possess the good forever, and that it leads the lover up a ladder from one beautiful body to the beauty of souls, laws and knowledge, and finally to Beauty itself. Plotinus and the Christian mystics took up the theme.
Eros
Desiring love: in Plato, the longing that draws the soul from beautiful bodies to Beauty itself.
