Man was born free but everywhere he is in chains (Rousseau). The modern world is characterized by diversity and escalating intolerance. From the early period of human thinking there has been a clear understanding that war is neither a natural phenomenon nor the irreversible will of God. The vision of world without war was embraced as the core approach to peace in Hellenic civilization. The conflict emerges from the pursuit of incompatible goals which intensify struggle between opposing forces specially in the absence of collaborative problem solving mechanisms. Conflict also arises because of the hegemony maintained by institutionalization of power relation. All history is the history of class struggle. All spiritual traditions also recognize the counter force of evil as a perennial problem in the human existence.
