What is to be done to prevent the increased exchanges between cultures, which should lead to a true and fruitful dialogue between groups and nations, from disturbing the life of communities, from destroying the wisdom received from ancestors, or from placing in danger the character proper to each people? How is the dynamism and expansion of a new culture to be fostered without losing a living fidelity to the heritage of tradition? This question is of particular urgency when a culture which arises from the enormous progress of science and technology must be harmonized with a culture nourished by classical studies according to various traditions. What can be done to make all men partakers of cultural values in the world, when the human culture of those who are more competent is constantly becoming more refined and more complex? (Second Vatican Council. Gaudium et Spes, 1965).
