"The peace of men is well-regulated harmony; […] the peace of all things is the tranquility of order. And order is the arrangement of equal and unequal beings that assigns to each his proper place." (AUGUSTINE, The City of God, XIX, 13, 1) Starting from a consideration of Augustine's reflection on the theme of peace and the path that can lead to it, and considering the challenges humanity faces today in the difficult and urgent effort to overcome the logic and practice of war in the regulation of interpersonal relations — both on the personal level and on the social and political one —, we explore the foundations and the present-day feasibility of a path to peacebuilding that looks to the ordo amoris as the horizon of full realization of human action, a criterion for discerning such action in light of a consideration — between freedom and responsibility — of its metaphysical, anthropological, and ethical foundations, as well as the telos toward which and by virtue of which we can courageously undertake paths of pacification with the potential contribution of all religions. By questioning the Augustinian position in light of some contemporary authors, the contemporary implications of this perspective are explored and discussed, verifying the feasibility — demanding but possible — of this path in a conscious and generative journey, capable of novelty and open to an eschatological horizon.
