This picture of today's world in which there is so much evil both physical and moral, so as to make of it a world entangled in contradictions and tensions, and at the same time full of threats to human freedom, conscience and religion-this picture explains the uneasiness felt by contemporary man. This uneasiness is experienced not only by those who are disadvantaged or oppressed, but also by those who possess the privileges of wealth, progress and power. And, although there is no lack of people trying to understand the causes of this uneasiness, or trying to react against it with the temporary means offered by technology, wealth or power, still in the very depth of the human spirit this uneasiness is stronger than all temporary means. This uneasiness concerns_the fundamental problems of all human existence. It is linked with the very sense of man's existence in the world, and is an uneasiness for the future of man and all humanity; it demands decisive solutions, which now seem to be forcing themselves upon the human race. (Papal Encyclical, Dives et misericordia, 30 November 1980).
