The objective of violence is to utterly defeat an enemy and then carry out one's plans unilaterally and without further resistance. The objective of nonviolence is to convince the opponent that he is incorrect, and then carry out one's plans with the cooperation of a new ally.
Violent force is the destructive force of coercion, weapons, revenge, and genocide.
Nonviolent force is the creative force of love, justice, and equality. So long as our humanity binds us together, there is not an evil in this world which is immune to nonviolent force. Now the question is posed to you. The task could be as quick as telling the someone you know that you appreciate them, or it could require a level of courage we rarely demand from ourselves. This is no simple task.
