It is not our affluence, or our plumbing, or our clogged freeways that grip the imagination of others. Rather, it is the values upon which our system is built. These values imply our adherence not only to liberty and individual freedom, but also to international peace, law and order, and constructive social purpose. When we depart from these values, we do so at our peril.

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.

Like medieval theologians we had a philosophy that explained everything to us in advance, and everything that did not fit could be readily identified as a fraud or a lie or an illusion... The perniciousness of the anti-Communist ideology of the Truman Doctrine arises not from any patent falsehood but from its distortion and simplification of reality, from its universalization and its elevation to the status of a revealed truth.

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.

The exchange program is the thing that reconciles me to all the difficulties of political life.

As a conservative power, the United States has a vital interest in upholding and expanding the reign of law in international relations.

We must dare to think 'unthinkable' thoughts. We must learn to explore all the options and possibilities that confront us in a complex and rapidly changing world.
