Regardless of your personal opinion on astrology, I highly recommend reading this informative *and* incisive article by Assistant Professor of History Darin Hayton: “What Exactly is Accomplished by Asserting ‘Astrology is Rubbish’?“. There’s some really good points made about pseudoskepticism, and the almost fanatical approach some scientists take when it comes to topics outside the gates of science:

Scientists claim that arguments from authority do not carry logical force. Yet they rely on them in almost every effort to dismiss astrology. They then claim that precession invalidate astrology and suggest that astrologers are dolts because they either do not know about precession or have not taken it into account. Yet astrologers have studied and accounted for precession since at least Ptolemy borrowed it from Hipparchus. The standard medieval textbook used to teach astrologers the basics of planetary motion, Gerard of Cremona’s Theorica planetarum, devoted a section to precession. Georg Peuerbach’s enhanced and improved version of this text, his Theoricae novae planetarum, devoted an entire chapter to precession.

…Whatever else might be the case, astronomers seem singularly unable to avoid denouncing astrology and equally incapable of persuading proponents of astrology to relinquish their conviction (or even to dissuade the astrology-curious). Maybe astronomers’ lack of success is related to the cavalier approach they adopt when attacking astrology. They certainly have not engaged with the body of knowledge they hope to refute. Instead, they attack caricatures and straw men. They argue from authority rather than logic. And they seem to ignore astrology’s technical details—such as anything approaching an understanding of positional astronomy—and ignorant of astrology’s history. To be fair, they have occasionally asked questions about possible mechanisms for astral influence, but then dismiss the very possibility of such a mechanism. No doubt they realize that their invectives do not constitute logically compelling arguments. So what then is the point of their denunciations? And whom are they trying to convince?

And what really is at stake in this enduring battle between science and astrology? Are astronomers afraid that their funding will suddenly go to astrologers? Does the fate of the free world or the rational mind or science depend on refuting astrology? Given the characterization of astrologers and believers in astrology as simple-minded, uneducated, irrational dupes, what threat do these people pose to astronomers and scientists? Does belief in astrology stand for a purported, societal-wide irrationality that threatens the entire practice of science? That seems a bit apocalyptic, but maybe. And what is served by the denigrating rhetoric typically used to brand astrologers frauds and charlatans? Surely it would be more effective to adopt a more conversational approach rather than labeling astrologers and their customers irrational, superstitious dupes.

But maybe despite its guise of rationality and argumentation, the anti-astrology polemic isn’t intended to persuade an opponent any more than any other polemic. Maybe it’s merely a secular form of “preaching to the choir.”
