Global Peace is the summum bonum, so we must know its negative as well as positive meanings. Simultaneously peace must be understood in all its interrelated but theoretically differentiated dimensions as personal, social, national, international and global. Today, humankind is suffering from multidimensional crises such as terrorism, population-explosion, denial of human rights, economic inequality, racial discrimination, ideological extremism, religious intolerance, social injustice, ecological imbalance, consumerism, oppression of weak, etc. These peace-related issues compel us to lay down the fundamental principles of a radical global ethics that expects us to realize our roles and duties regarding global peace. It includes the role and ideals of educationalists, the duties of scientists, philosophers, and thinkers, the inculcation of human values such as nonviolence, love, etc.
