John Adams writes an open letter to the New York Times in response to its NSA spying story

[L]iberty cannot be preserved without a general knowledge among the people, who have a right ... to knowledge ... and a desire to know; but besides this, they have a right, an indisputable, unalienable, indefeasible, divine right to that most dreaded and envied kind of knowledge, I mean, of the characters and conduct of their rulers. Rulers are no more than attorneys, agents, and trustees for the people; and if the cause, the interest and trust, is insidiously betrayed, or wantonly trifled away, the people have a right to revoke the authority that they themselves have deputed, and to constitute abler and better agents, attorneys, and trustees ...

The stale, impudent insinuations of slander and sedition, with which the gormandizers of power have endeavored to discredit your paper, are so much the more to your honor; for the jaws of power are always opened to devour, and her arm is always stretched out, if possible, to destroy the freedom of thinking, speaking, and writing. And if the public interest, liberty, and happiness have been in danger from the ambition or avarice of any great man, whatever may be his politeness, address, learning, ingenuity, and, in other respects, integrity and humanity, you have done yourselves honor and your country service by publishing and pointing out that avarice and ambition. These vices are so much the more dangerous and pernicious for the virtues with which they may be accompanied in the same character, and with so much the more watchful jealousy to be guarded against.

"Curse on such virtues, they've undone their country."

Be not intimidated, therefore, by any terrors, from publishing with the utmost freedom, whatever can be warranted by the laws of your country; nor suffer yourselves to be wheedled out of your liberty by any pretences of politeness, delicacy, or decency. These, as they are often used, are but three different names for hypocrisy, chicanery, and cowardice.
