  If pacifism is defined as a commitment to nonviolence, we encounter the same problem of definition.  Violence usually has a normative value and is defined as something like “an unjustified injury or harm.” But it is possible to speak of justified violence—as in the just war ideal; so not all violence is unjustified. The concept of violence can also be extended metaphorically and used as an adjective—“violent”—to mean something like unbridled, uncontrolled, rough, or intense. Thus we speak of “violent storms” or “violent emotions.” A commitment to nonviolence is, at least, a commitment to avoiding unjustified intentional injury. Pacifists will tend to think that most intentionally caused harms are unjustifiable.  But the ideal of nonviolence might be extended to include the idea of controlling rough and intense emotions. In his essay, “Journey to Nonviolence,” for example, Martin Luther King Jr. claimed that a commitment to nonviolence required overcoming the “internal violence” of hatred and anger by cultivating love and compassion (King 1986, 46).
