There are two branches of love: Eros and Agape.
Eros is grounded in desire. It is the desire for individuated oneness with the beloved other. Ultimately it is the desire for union with God.
Agape is grounded in the will. To act out of Agape is to will the well-being of the other. Agape becomes manifest in four mortalities: emotion, behavior, thinking, and social relations. If it does not become manifest in behavior, thinking and social relations as well as emotions, it is sentimentality. Agape acts in ways that are tailored to further the well-being of others. It thinks about others, with the intent to understand them without judgment. And it enters into relationships with others that it believes will be helpful to them.
Agape is not superior to Eros. But it complements and gives direction to Eros. Without agape, Eros quickly descends into prurience.
