PZ Myers highlights a quote from Irving Kristol, a big fan of Leo Strauss’ political philosophy:

“There are different kinds of truths for different kinds of people,” he says in an interview. “There are truths appropriate for children; truths that are appropriate for students; truths that are appropriate for educated adults; and truths that are appropriate for highly educated adults, and the notion that there should be one set of truths available to everyone is a modern democratic fallacy. It doesn’t work.”

As PZ Myers correctly points out, what Kristol is really talking about is lying. But I’ve seen this before: people being ready to use the word “truth” when they really mean anything but. Such confuses seem to underwrite a fair portion of the denials of objective reality you see out there.
