Origin:  Plato was an ancient Greek philosopher who wrote on the interesting subject of love. Platonic love and platonic friendships are marked by the absence of physical or sexual desire. Plato did acknowledge physical desire, but thought that if two people truly inspired each other, their spiritual or ideal love would bring them closer to God.
