Man was born into barbarism when killing his fellow man was a normal condition of existence. He became endowed with a conscience. And he has now reached the day when violence toward another human being must become as abhorrent as eating another's flesh. Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that. Hate multiplies hate, violence multiplies violence, and toughness multiplies toughness in a descending spiral of destruction. The chain reaction of evil--hate begetting hate, wars producing more wars--must be broken, or we shall be plunged into the dark abyss of annihilation...

The past is prophetic in that it asserts loudly that wars are poor chisels for carving out peaceful tomorrows.
