ANDREA SEABROOK, host:
Parting words tonight are from Ludwig Wittgenstein. Wittgenstein. He was the Austrian philosopher. He intensely studied math and logic and language, so you might think he'd say intensely serious things. Instead he warned, never stay up on the barren heights of cleverness, but come down into the green valleys of silliness.
(Soundbite of "Sandpaper Ballet")
