The leader thinkers generally consider peace in terms of the resolution or absence of war, violence, or conflict, or at least as conflict management. For instance, Boulding and Galtung consider peace as the absence of war, violence, conflict and peacemaking in terms of international relations. Others consider peace in terms of harmony within the individual, or between individuals, and peacemaking as a mode of relating to others based on some unarticulated internal emotional or cognitive state.
