In a democracy dissent is an act of faith. Like medicine, the test of its value is not in its taste, but in its effects.

Quotes from the same author

The age of warrior kings and of warrior presidents has passed. The nuclear age calls for a different kind of leadership.... a leadership of intellect, judgment, tolerance and rationality, a leadership committed to human values, to world peace, and to the improvement of the human condition. The attributes upon which we must draw are the human attributes of compassion and common sense, of intellect and creative imagination, and of empathy and understanding between cultures.

The essence of intercultural education is the acquisition of empathy-the ability to see the world as others see it, and to allow for the possibility that others may see something we have failed to see, or may see it more accurately. The simple purpose of the exchange program...is to erode the culturally rooted mistrust that sets nations against one another. The exchange program is not a panacea but an avenue of hope.

The junior Senator from Wisconsin, by his reckless charges, has so preyed upon the fears and hatred of uninformed and credulous people that he has started a prairie fire, which neither he nor anyone else may be able to control.

Educational exchange can turn nations into people, contributing as no other form of communication can to the humanizing of international relations. Man's capacity for decent behavior seems to vary directly with his perception of others as individual humans with human motives and feelings, whereas his capacity for barbarism seems related to his perception of an adversary in abstract terms, as the embodiment, that is, of some evil design or ideology.

When public men indulge themselves in abuse, when they deny others a fair trial, when they resort to innuendo and insinuation, to libel, scandal, and suspicion, then our democratic society is outraged, and democracy is baffled. It has no apparatus to deal with the boor, the liar, the lout, and the antidemocrat in general.
