Word History: Plato did not invent the term or the concept that bears his name, but he did see sexual desire as the germ for higher loves. Marsilio Ficino, a Renaissance follower of Plato, used the terms amor socraticus and amor platonicus interchangeably for a love between two humans that was preparatory for the love of God. From Ficino's usage, Platonic (already present in English as an adjective to describe what related to Plato and first recorded in 1533) came to be used for a spiritual love between persons of opposite sexes. In our own century Platonic has been used of relationships between members of the same sex. Though the concept is an elevated one, the term has perhaps more often been applied in ways that led Samuel Richardson to have one of his characters in Pamela say, "I am convinced, and always was, that Platonic love is Platonic nonsense."
