The use of violence in our struggle would be both impractical and immoral. To meet hate with retaliatory hate would do nothing but intensify the existence of evil in the universe. Hate begets hate; violence begets violence; toughness begets a greater toughness. We must meet the forces of hate with the power of love; we must meet physical force with soul force. Our aim must never be to defeat or humiliate the white man, but to win his friendship and understanding.
