"No one who examines the modern world can doubt that the great currents of history are carrying the world away from the monolithic idea towards the pluralistic idea--away from communism and towards national independence and freedom. No one can doubt that the wave of the future is not the conquest of the world by a single dogmatic creed but the liberation of the diverse energies of free nations and free men. No one can doubt that cooperation in the pursuit of knowledge must lead to freedom of the mind and freedom of the soul."
