An old post of mine - from the middle of 2007 – has recently been replied to by someone who takes their astrology very seriously. Anthony Louis, who has published books on astrology and tarot, runs quite an active blog on the topics. His somewhat curious response is quite short so I’ll quote it in full before analysing it:
Because of the way Louis has phrased things it is not clear to what degree he is aiming his comments at the definition, at my stated views or at the views of scientists in general. Certainly, he gives no indication that he has read anything else from my blog. Indeed, he gives no indication that he understands that my original post is a criticism of the dictionary definition he quotes out of my post. So, I would agree that it is problematic that the notion of superstition is relativised to each person’s individual standards of evidence. Such a definition might work well in a normal dictionary but not in a scientific dictionary. Having said that, the definition is clearly not circular. He has simply used the wrong term there.
However, Louis goes beyond the bad definition to reach all sorts of conclusions that are far from valid. In particular, he seems to assume that the definition is the latest and best word on superstition. How else to understand his apparent conclusion that the term must be purely derogatory? It is almost as if none of the work done over the last century to provide a scientific understanding of supernatural beliefs and practices existed. It is possible to argue, of course, that the term ‘superstition’ is too value-laden to make it appropriate to use in a scientific context. That is a view that has some merit and, indeed, I have largely moved to referring to magical practices, rather than superstitions. But a bad definition in no way settles that issue. One could just as well define astrology as a simple superstition and claim to have proved something. Logic does not work that way.
Louis’ less than lucid thinking is garnished with the kind of “namecalling” he protests against when it is aimed at him. How else to understand the trite comparison between calling something a superstition and the execution of heretics. If Louis finds himself threatened with immolation for reading tarot cards, I will agree with him. Until then, I will think it failure of morality and imagination to compare the use of a derogatory term with the horrors of the Inquisition. The ideal of the Enlightenment, which was in part a reaction against these kinds of horrors, was to allow people to disagree and criticise each other without resorting to force. The flip side of that is that calling someone’s beliefs irrational is an essential part of rational discourse.
Having said all that, I do not actually think astrology is a simple superstition. There is nothing simple about it. I would compare the difference between it and superstitions to the difference between theology and popular religion. As Robert McCauley explains, theology is the attempt to render coherent a set of culturally stabilised and cognitively attractive beliefs about supernatural entities that in their original form are nothing but coherent. Similarly, astrology is the attempt to render coherent a set of such beliefs about using astronomical objects to divine claims that concern particular humans. Of course, the old computer science principle of GIGO applies (it is a wonderful coincidence that the second G is sometimes taken to stand for ‘gospel’). Neither theology nor astrology would exist were it not for the cognitively attractive folk beliefs and practices that provide their respective justifications. What is more, the pronouncements of theology and astrology have no more basis in reality than those folk beliefs. Kind of like folk intuitions and traditional philosophy.

Thanks for your thoughtful response to my post. By citing your post on superstition, I was simply trying to give you credit for calling my attention to the Penguin Dictionary definition, and it was in now way intended as a criticism of your article. In fact, I liked what you had to say and linked to your blog to send more readers your way.
As a serious student of astrology, I am often put off by people simply dismissing it as “superstition” when they have no idea what it is about or how intellectually sophisticated it is as a field of study. I’m also more cynical than you are about the Enlightenment. As I look at the world, I see many nations and peoples who run their lives on the basis of primitive orthodox religious beliefs that sometimes lead them to murder non-believers. There may be small pockets of enlightenment around the globe, but there are large areas of the world still living in the dark ages.
Maybe I didn’t make it clear in my post, but I was really calling for more tolerance of viewpoints we don’t agree with or understand.

Thanks for the comments. As I hope I made clear my post, I realise that professional astrology is intellectually sophisticated. I still think that the word ‘superstition’ applies, in so far as it applies to anything.
While I agree that we are far from the ideal that the philosophes imagined, I do think that the world has been fundamentally altered for the better by the willingness of many people to work for Enlightnment values.
Finally, I obviously agree with the basic idea that tolerance and respect are good things but I think that what is meant by that needs to be clarified. For example, I think that by letting you know that I think some of your beliefs are irrational I am showing respect for your intellectual ability. But that is a point that I really ought to expand into a full post at some time.

Edit thought:
I think the last word should read “incoherent” or, the last phrase should read, “anything but coherent”.
That said, Anthony Louis’ comment said:
which appears to be a bit oblivious to the import of your statement that:
If he linked to this post, perhaps some of his readers will understand how undercutting your criticism rightfully is.
