We cannot presume that the future will resemble the past—that things and patterns we have relied upon economically, politically, socially will remain as they have been. Perhaps our moral discipline, if we will cultivate it, will have an influence for good and inspire others to pursue the same course. We may thereby have an impact on future trends and events. At a minimum, moral discipline will be of immense help to us as we deal with whatever stresses and challenges may come in a disintegrating society.
