Man is suddenly becoming aware that by an ill-considered exploitation of nature he risks destroying it and becoming in his turn the victim of this degradation. Not only is the material environment becoming a permanent menace - pollution and refuse, new illness and absolute destructive capacity - but the human framework is no longer under man's control, thus creating an environment for tomorrow which may well be intolerable. This is a wide-ranging social problem which concerns the entire human family.
Pope Paul VITrue humanism points the way toward God and acknowledges the task to which we are called, the task which offers us the real meaning of human life. Man is not the ultimate measure of man. Man becomes truly man only by passing beyond himself.
Pope Paul VIThe transmission of human life is a most serious role in which married people collaborate freely and responsibly with God the Creator.
Pope Paul VIThis world in which we live needs beauty in order not to sink into despair. It is beauty, like truth, which brings joy to the heart of man and is that precious fruit which resists the year and tear of time, which unites generations and makes them share things in admiration.
