Self-development through love: "Some progressive psycholoanalysts, however, tended rather towards the Grecian idea of Eros (eg. Plato's Symposium), a primal urge that began through erotic physical love but subsequently rose to higher levels and expanded in scope towards the incorporeal realm of ideas until love of wisdom and of the ultimate good were reached. This Socratic/Platonic view of love intelligently makes discovery of its universal nature dependent on a long prior educational and maturing process."
