"One of the most salient features of our culture is that there is so much bullshit. Everyone knows this." -- A Princeton philosopher is stirring up a you-know-what-storm with his new treatise, "On Bullshit," the title of which the NYTimes, in its modesty, won't print. Prof. Frankfurt makes a compelling point: B.S. artists are not the same as liars, who reject truth; all a bullshitter cares about is "getting away with what he says," which undermines the institutions he represents. Sound like anyone we know? Yikes.
