To ask for overt renunciation of a cherished doctrine is to expect too much of human nature. Men do not repudiate the doctrines and dogmas to which they have sworn their loyalty. Instead they rationalize, revise, and re-interpret them to meet new needs and new circumstances, all the while protesting that their heresy is the purest orthodoxy.

This is regrettable indeed for a nation that aspires to teach democracy to other nations, because, as Burke said: "Example is the school of mankind, and they will learn at no other."

The preservation of our free society in the years and decades to come will depend ultimately on whether we succeed or fail in directing the enormous power of human knowledge to the enrichment of our own lives and the shaping of a rational and civilized world order....It is the task of education, more than any other instrument of foreign policy to help close the dangerous gap between the economic and technological interdependence of the people of the world and their psychological, political and spiritual alienation.

Education is a slow-moving but powerful force. It may not be fast enough or strong enough to save us from catastrophe, but it is the strongest force available for that purpose and in its proper place, therefore, is not at the periphery, but at the center of international relations.

It's unnatural and unhealthy for a nation to be engaged in global crusades for some principle or idea while neglecting the needs of its own people.

....Man's struggle to be rational about himself, about his relationship to his own society and to other peoples and nations involves a constant search for understanding among all peoples and all cultures-a search that can only be effective when learning is pursued on a worldwide basis.

In the long course of history, having people who understand your thought is much greater security than another submarine.
