“A republic cannot succeed, till it contains a certain body of men imbued with the principles of justice and honour.”

Context: The complete independence of the Courts of justice is peculiarly essential in a limited Constitution. By a limited Constitution, I understand one which contains certain specified exceptions to the Legislative authority; such, for instance, as that it shall pass no bills of attainder, no ex post facto laws, and the like. Limitations of this kind can be preserved in practice no other way than through the medium of the Courts of justice; whose duty it must be to declare all Acts contrary to the manifest tenor of the Constitution void. Without this, all the reservations of particular rights or privileges would amount to nothing.

1961, Address to ANPA
Context: Without debate, without criticism, no Administration and no country can succeed — and no republic can survive. That is why the Athenian lawmaker Solon decreed it a crime for any citizen to shrink from controversy. And that is why our press was protected by the First Amendment — the only business in America specifically protected by the Constitution- -not primarily to amuse and entertain, not to emphasize the trivial and the sentimental, not to simply "give the public what it wants" — but to inform, to arouse, to reflect, to state our dangers and our opportunities, to indicate our crises and our choices, to lead, mold, educate and sometimes even anger public opinion.
This means greater coverage and analysis of international news — for it is no longer far away and foreign but close at hand and local. It means greater attention to improved understanding of the news as well as improved transmission. And it means, finally, that government at all levels, must meet its obligation to provide you with the fullest possible information outside the narrowest limits of national security — and we intend to do it.
