Finding the occasional straw of truth awash in a great ocean of confusion and
bamboozle requires intelligence, vigilance, dedication and courage. But if we
don’t practice these tough habits of thought, we cannot hope to solve the truly
serious problems that face us — and we risk becoming a nation of suckers, up
for grabs by the next charlatan who comes along.
