The tensions disturbing the world of today are in fact related to a more fundamental tension rooted in the human heart. In man himself many elements are in conflict with each other. On one side, he has experience of his many limitations as a creature. On the other, he knows that there is no limit to his aspirations, and that he is called to a higher kind of life. Many things compete for his attention, but he is always compelled to make a choice among them, and to renounce some. What is more, in his weakness and sinfulness he often does what he does not want to do, and fails to do what he would like to do. In consequence, he suffers from a conflict within himself, and this in turn gives rise to so many great tensions in society.
