"I still believe that love is the most durable power in the world. Over the centuries men have sought to discover the highest good. This has been the chief quest of ethical philosophy. This was one of the big questions of Greek philosophy. The Epicureans and the Stoics sought to answer it; Plato and Aristotle sought to answer it. What is the summum bonum* of life? I think I have discovered the highest good. It is love. This principle stands at the center of the cosmos. As John says, “God is love.^” He who loves is a participant in the being of God. He who hates does not know God."  --Martin Luther King, Jr.
