Context: I own any form of humor shows fear and inferiority. Irony is simply a kind of guardedness. So is a twinkle. It keeps the reader from criticism. Whittier, when he shows any style at all is probably a greater person than Longfellow as he is lifted priestlike above consideration of the scornful. Belief is better than anything else, and it is best when rapt, above paying its respects to anybody's doubt whatsoever. At bottom the world isn't a joke. We only joke about it to avoid an issue with someone to let someone know that we know he's there with his questions: to disarm him by seeming to have heard and done justice to this side of the standing argument. Humor is the most engaging cowardice.

Quotes 2000s, 2002
Context: [Israel's military occupation is] in gross violation of international law and has been from the outset. And that much, at least, is fully recognized, even by the United States, which has overwhelming and, as I said, unilateral responsibility for these crimes. So George Bush No. 1, when he was the U. N. ambassador, back in 1971, he officially reiterated Washington's condemnation of Israel's actions in the occupied territories. He happened to be referring specifically to occupied Jerusalem. In his words, actions in violation of the provisions of international law governing the obligations of an occupying power, namely Israel. He criticized Israel's failure "to acknowledge its obligations under the Fourth Geneva Convention as well as its actions which are contrary to the letter and spirit of this Convention." [... ] However, by that time, late 1971, a divergence was developing, between official policy and practice. The fact of the matter is that by then, by late 1971, the United States was already providing the means to implement the violations that Ambassador Bush deplored. [... ] on December 5th [2001], there had been an important international conference, called in Switzerland, on the 4th Geneva Convention. Switzerland is the state that's responsible for monitoring and controlling the implementation of them. The European Union all attended, even Britain, which is virtually a U. S. attack dog these days. They attended. A hundred and fourteen countries all together, the parties to the Geneva Convention. They had an official declaration, which condemned the settlements in the occupied territories as illegal, urged Israel to end its breaches of the Geneva Convention, some "grave breaches," including willful killing, torture, unlawful deportation, unlawful depriving of the rights of fair and regular trial, extensive destruction and appropriation of property not justified by military necessity and carried out unlawfully and wantonly. Grave breaches of the Geneva Convention, that's a serious term, that means serious war crimes. The United States is one of the high contracting parties to the Geneva Convention, therefore it is obligated, by its domestic law and highest commitments, to prosecute the perpetrators of grave breaches of the conventions. That includes its own leaders. Until the United States prosecutes its own leaders, it is guilty of grave breaches of the Geneva Convention, that means war crimes. And it's worth remembering the context. It is not any old convention. These are the conventions established to criminalize the practices of the Nazis, right after the Second World War. What was the U. S. reaction to the meeting in Geneva? The U. S. boycotted the meeting... and that has the usual consequence, it means the meeting is null and void, silence in the media.
