It pains Us, therefore, to observe the complete indifference to the true hierarchy of values shown by so many people in the economically developed countries. Spiritual values are ignored, forgotten or denied, while the progress of science, technology and economics is pursued for its own sake, as though material well-being were the be-all and end-all of life. This attitude is contagious, especially when it infects the work that is being done for the less developed countries, which have often preserved in their ancient traditions an acute and vital awareness of the more important human values, on which the moral order rests. (Papal Encyclical, Mater et Magistra, 15 May 1961).
It is essential, therefore, that the values chosen and pursued in one's life be true, because only true values can lead people to realize themselves fully, allowing them to be true to their nature. The truth of these values is to be found not by turning in on oneself but by opening oneself to apprehend that truth even at levels which transcend the person. This is an essential condition for us to become ourselves and to grow as mature, adult persons. (Papal Encyclical, Fides et Ratio, 14 September 1998).
