"Hate begets hate; violence begets violence; toughness begets a greater toughness. We must meet the forces of hate with the power of love. 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."
