There is an inevitable divergence between the world as it is and the world as men perceive it.

To criticize one's country is to do it a service.... Criticism, in short, is more than a right; it is an act of patriotism-a higher form of patriotism, I believe, than the familiar rituals and national adulation.

Educational exchange can turn nations into people, contributing as no other form of communication can to the humanizing of international relations

Education is the best means-probably the only means-by which nations can cultivate a degree of objectivity about each other's behavior and intentions. It is the means by which Russians and Americans can come to understand each others' aspirations for peace and how the satisfactions of everyday life may be achieved.
