62. There are other obstacles to creation of a more just social order and to the development of world solidarity: nationalism and racism. It is quite natural that nations recently arrived at political independence should be quite jealous of their new-found but fragile unity and make every effort to preserve it. It is also quite natural for nations with a long-standing cultural tradition to be proud of their traditional heritage. But this commendable attitude should be further ennobled by love, a love for the whole family of man. Haughty pride in one's own nation disunites nations and poses obstacles to their true welfare. It is especially harmful where the weak state of the economy calls for a pooling of information, efforts and financial resources to implement programs of development and to increase commercial and cultural interchange. . . . and Racism
63. Racism is not the exclusive attribute of young nations, where sometimes it hides beneath the rivalries of clans and political parties, with heavy losses for justice and at the risk of civil war. During the colonial period it often flared up between the colonists and the indigenous population, and stood in the way of mutually profitable understanding, often giving rise to bitterness in the wake of genuine injustices. It is still an obstacle to collaboration among disadvantaged nations and a cause of division and hatred within countries whenever individuals and families see the inviolable rights of the human person held in scorn, as they themselves are unjustly subjected to a regime of discrimination because of their race or their color.
