Last week I heard an excerpt from the Senate confirmation hearings for Condoleezza Rice to be Secretary of State. California Senator Barbara Boxer said, after having run through a list of Rice's statements in the lead up to war, "Your loyalty to the mission [invading Iraq] ... overwhelmed your respect for the truth."
To which Rice replied, "I'd like to [discuss this] in such a way that it does not impugn my integrity."
That night the local PBS station was airing some sort of guide on buying antiques. The show's host demonstrated how to ask a dealer questions about a piece of interest. Ask where the dealer acquired the piece, what he knows about its history, has he himself made any repairs, etc. The host pulled out a drawer and pointed out a hidden repair to the back end of the drawer. The dealer nodded, made a couple additional comments ... When he'd walked away the host said to the camera (I'm paraphrasing), "That dealer was honest and upfront. He answered my questions quickly and matter-of-factly. Beware the dealer who says, when you point out a flaw in the piece (and a possible contradiction in what he's so far told you), 'Are you trying to impugn my integrity?'"
