Platonic love is a type of love that is chaste and non-sexual. The term is named after Plato, who philosophised about the nature of love. Platonic love in this original sense of the term is examined in Plato’s dialogue the Symposium, which has as its topic the subject of love or Eros generally. It explains the possibilities of how the feeling of love began, and how it has evolved—both sexually and non-sexually.
