To rebel against a powerful political, economic, religious, or social estab- lishment is very dangerous and very few people do it, except, perhaps, as part of a mob. To rebel against the "scientific" establishment, however, is the easiest thing in the world, and anyone can do it and feel enormously brave, without risking as much as a hangnail. Thus, the vast majority, who believe in astrology and think that the planets have nothing better to do than form a code that will tell them whether tomorrow is a good day to close a business deal or not, become all the more excited and enthusiastic about the bilge when a group of astronomers denounces it.
