61 Today it is more difficult to form a synthesis of the various disciplines of knowledge and the arts than it was formerly. For while the mass and the diversity of cultural factors are increasing, there is a decrease in each man's faculty of perceiving and unifying these things, so that the image of "universal man" is being lost sight of more and more. Nevertheless it remains each man's duty to retain an understanding of the whole human person in which the values of intellect, will, conscience and fraternity are preeminent. These values are all rooted in God the Creator and have been wonderfully restored and elevated in Christ. The family is, as it were, the primary mother and nurse of this education. There, the children, in an atmosphere of love, more easily learn the correct order of things, while proper forms of human culture impress themselves in an almost unconscious manner upon the mind of the developing adolescent. Opportunities for the same education are to be found also in the societies of today, due especially to the increased circulation of books and to the new means of cultural and social communication which can foster a universal culture. With the more or less generalized reduction of working hours, the leisure time of most men has increased. May this leisure be used properly to relax, to fortify the health of soul and body through spontaneous study and activity, through tourism which refines man's character and enriches him with understanding of others, through sports activity which helps to preserve equilibrium of spirit even in the community, and to establish fraternal relations among men of all conditions, nations and races. Let Christians cooperate so that the cultural manifestations and collective activity characteristic of our time may be imbued with a human and a Christian spirit. All these leisure activities however are not able to bring man to a full cultural development unless there is at the same time a profound inquiry into the meaning of culture and science for the human person.
