There is nothing obscure about the objectives of educational exchange. Its purpose is to acquaint Americans with the world as it is and to acquaint students and scholars from many lands with America as it is-not as we wish it were or as we might wish foreigners to see it, but exactly as it is-which by my reckoning is an "image" of which no American need be ashamed.

Intolerance of dissent is a well-noted feature of the American national character.

In a democracy, dissent is an act of faith.

We must care to think about the unthinkable things, because when things become unthinkable, thinking stops and action becomes mindless.

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.

I think we Americans tend to put too high a price on unanimity, as if there were something dangerous and illegitimate about honest differences of opinion honestly expressed by honest men.

I do not think it is "selling America short" when we ask a great deal of her; on the contrary, it is those who ask nothing, those who see no fault, who are really selling America short!
