A thoughtful piece on this topic from the always-worth-reading William Wildblood:
Like most scientists, I used to regard Astology as utterly ridiculous; but having discovered more about the real medieval context (from reading CS Lewis, especially The Discarded Image); and then finding the subject treated by authors I respect such as William Arkle and William Wildblood himself - I tend to think that there 'must be something in it', although it isn't a thing I am personally attracted to.
Anyway, William W. and I had an email exchange last weekend, during which he very generously offered to do my personal 'character' horoscope based on the exact time and place of birth (but not a full interpretation - which would have taken a very long time).
The result was something like a detailed personality evaluation. I then spent a day brooding over it, and discussing it with my wife - and the conclusion was that it was more right than wrong by a comfortable ratio of about 2:1.
So, 'something in it', it seems.
