In a recent post, I mentioned an article in the Washington Post by Susan Jacoby called, "The Dumbing of America." She has also written a book called, "The Age of American Unreason." I have not yet read the book, but it is on my Amazon.com Wish List.
Bill Moyers interviewed Susan Jacoby recently and she discussed, "how a 'flight from reason' is playing out in American politics and society. 'We have really, over the past 40 years, gotten shorter and shorter and shorter attention spans,' says Jacoby."
It is worth listening to here.
