New efforts are needed if this Assembly's Declaration of Human Rights, now 15 years old, is to have full meaning. And new means should be found for promoting the free expression and trade of ideas—through travel and communication, and through increased exchanges of people, and books, and broadcasts. For as the world renounces the competition of weapons, competition in ideas must flourish—and that competition must be as full and as fair as possible.
