Since the Fall man has been haunted by the vision of peace, of a state in which the fulfilment of desire would be complete and undisturbed. The longing for peace is as universal as desire itself; for the very idea of desire includes the wish for peace, inasmuch as the full enjoyment of any coveted good can only be ensured by peace. Even wars, as St Thomas points out, are only fought for the sake of peace, in order to bring about conditions more satisfactory than the prevailing ones; while the very restlessness and sensationalism of an age merely indicates that the pursuit of genuine peace has been given up as impossible of fulfilment.
