This development coming so rapidly and often in a disorderly fashion, combined with keener awareness itself of the inequalities in the world beget or intensify contradictions and imbalances. Within the individual person there develops rather frequently an imbalance between an intellect which is modern in practical matters and a theoretical system of thought which can neither master the sum total of its ideas, nor arrange them adequately into a synthesis. Likewise an imbalance arises between a concern for practicality and efficiency, and the demands of moral conscience; also very often between the conditions of collective existence and the requisites of personal thought, and even of contemplation. At length there develops an imbalance between specialized human activity and a comprehensive view of reality. The truth is that the imbalances under which the modern world labours are linked with that more basic imbalance which is rooted in the heart of man. For in man himself many elements wrestle with one another. Thus, on the one hand, as a creature he experiences his limitations in a multitude of ways; on the other he feels himself to be boundless in his desires and summoned to a higher life. Pulled by manifold attractions he is constantly forced to choose among them and renounce some. Indeed, as a weak and sinful being, he often does what he would not, and fails to do what he would. Hence he suffers from internal divisions, and from these flow so many and such great discords in society. No doubt many whose lives are infected with a practical materialism are blinded against any sharp insight into this kind of dramatic situation; or else, weighed down by unhappiness they are prevented from giving the matter any thought. Thinking they have found serenity in an interpretation of reality everywhere proposed these days, many look forward to a genuine and total emancipation of humanity wrought solely by human effort; they are convinced that the future rule of man over the earth will satisfy every desire of his heart. Nor are there lacking men who despair of any meaning to life and praise the boldness of those who think that human existence is devoid of any inherent significance and strive to confer a total meaning on it by their own ingenuity alone. (Second Vatican Council. Gaudium et Spes, 1965).
