Profound and rapid changes make it more necessary that no one ignoring the trend of events or drugged by laziness, content himself with a merely individualistic morality. It grows increasingly true that the obligations of justice and love are fulfilled only if each person, contributing to the common good, according to his own abilities and the needs of others, also promotes and assists the public and private institutions dedicated to bettering the conditions of human life. Yet there are those who, while professing grand and rather noble sentiments, nevertheless in reality live always as if they cared nothing for the needs of society. Many in various places even make light of social laws and precepts, and do not hesitate to resort to various frauds and deceptions in avoiding just taxes or other debts due to society. Others think little of certain norms of social life, for example those designed for the protection of health, or laws establishing speed limits; they do not even avert to the fact that by such indifference they imperil their own life and that of others. (Second Vatican Council. Gaudium et Spes 1965).
