31 In order for individual men to discharge with greater exactness the obligations of their conscience toward themselves and the various group to which they belong, they must be carefully educated to a higher degree of culture through the use of the immense resources available today to the human race. Above all the education of youth from every social background has to be undertaken, so that there can be produced not only men and women of refined talents, but those great-souled persons who are so desperately required by our times. Now a man can scarcely arrive at the needed sense of responsibility, unless his living conditions allow him to become conscious of his dignity, and to rise to his destiny by spending himself for God and for others. But human freedom is often crippled when a man encounters extreme poverty just as it withers when he indulges in too many of life's comforts and imprisons himself in a kind of splendid isolation. Freedom acquires new strength, by contrast, when a man consents to the unavoidable requirements of social life, takes on the manifold demands of human partnership, and commits himself to the service of the human community. Hence, the will to play one's role in common endeavors should be everywhere encouraged. Praise is due to those national procedures which allow the largest possible number of citizens to participate in public affairs with genuine freedom. Account must be taken, to be sure, of the actual conditions of each people and the decisiveness required by public authority. If every citizen is to feel inclined to take part in the activities of the various groups which make up the social body, these must offer advantages which will attract members and dispose them to serve others. We can justly consider that the future of humanity lies in the hands of those who are strong enough to provide coming generations with reasons for living and hoping.
