106 Before leaving this subject of the contemporary world, We feel impelled to mention Our cherished hope that this intention of Ours of holding a dialogue and of developing it under all the various and changing aspects which it presents, may assist the cause of peace among men. May it point the way to prudence and sincerity in the ordering of human relationships, and bring experience and wisdom to bear on the problem of recalling all men to the consideration of supernatural values. The mere fact that we are embarking upon a disinterested, objective and sincere dialogue is a circumstance in favor of a free and honorable peace. It positively excludes all pretence, rivalry, deceit and betrayal. It brands wars of aggression, imperialism, and domination as criminal and catastrophic. It necessarily brings men together on every level: heads of states, the body of the nation and its foundations, whether social, family, or individual. It strives to inspire in every institution and in every soul the understanding and love of peace and the duty to preserve it.
