Platonic love is a type of love in which sexual desire or romantic features are nonexistent or have been suppressed or sublimated, but it means more than simple friendship.
The term is derived from the name of Greek philosopher Plato, though the philosopher never used the term himself. Platonic love, as devised by Plato, concerns rising through levels of closeness to wisdom and true beauty, from carnal attraction to individual bodies to attraction to souls, and eventually, union with the truth.
Platonic love is contrasted with romantic love.
Platonic love is examined in Plato's dialogue, the Symposium, which has as its topic the subject of love, or more generally the subject of Eros. It explains the possibilities of how the feeling of love began and how it has evolved, both sexually and non-sexually, and defines genuine platonic love as inspiring a person's mind and soul and directing their attention towards spiritual matters. Of particular importance is the speech of Socrates, who attributes to the prophet Diotima an idea of platonic love as a means of ascent to contemplation of the divine, an ascent known as the "Ladder of Love". For Diotima and Plato generally, the most correct use of love of human beings is to direct one's mind to love of divinity. Socrates defines love based on separate classifications of pregnancy (to bear offspring); pregnancy of the body, pregnancy of the soul, and direct connection to existence. Pregnancy of the body results in human children. Pregnancy of the soul, the next step in the process, produces "virtue"—which is the soul (truth) translating itself into material form. "... virtue for the Greeks means self-sameness ... in Plato's terms, Being or idea."(106)
Pausanias, in Plato's Symposium (181b–182a), defines two types of the love known as "Eros": vulgar Eros, or earthly love, and divine Eros, or divine love. Pausanias defines vulgar Eros as material attraction towards a person's beauty for the purposes of physical pleasure and reproduction, and divine Eros as starting from physical attraction but transcending gradually to love for supreme beauty, placed on a similar level to the divine.
