Carl Sagan is one of my favorite authors. His book, 'The Demon-Haunted
World" is a classic, and is essential reading for the budding skeptic. A
quote from that book is eerily prophetic:

"I have a foreboding of an America in my children's or grandchildren's time
-- when the United States is a service and information economy; when nearly
all the manufacturing industries have slipped away to other countries; when
awesome technological powers are in the hands of a very few, and no one
representing the public interest can even grasp the issues; when the people
have lost the ability to set their own agendas or knowledgeably question
those in authority; when, clutching our crystals and nervously consulting
our horoscopes, our critical faculties in decline, unable to distinguish
between what feels good and what's true, we slide, almost without noticing,
back into superstition and darkness."
