The Demon-Haunted World: Science as a Candle in the Dark

by Carl Sagan

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 key 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.

every time we exercise self-criticism, every time we test our ideas against the outside world, we are doing science. When we are self-indulgent and uncritical, when we confuse hopes and facts, we slide into pseudoscience and superstition.

We are enjoined in Micah to do justly and love mercy; in Exodus we are forbidden to commit murder; in Leviticus we are commanded to love our neighbor as ourselves; and in the Gospels we are urged to love our enemies. Yet think of the rivers of blood spilled by fervent followers of the books in which these well-meaning exhortations are embedded.
