Might the public do better to classify astrology as a spirituality? Nearly all cultures who practiced ancient astrology firmly believed that deities, crystal spheres, or otherwise supernatural forces were responsible for moving heavenly bodies, and it was human responsibility to puzzle the meanings of the positions out.
The first post indicates that the assumption of gravitational forces acting as that power of the planets upon humans is incorrect. Besides this, I’ve met no atheists who believe in astrology. A few Neopagan friends of mine, with whom I recently shared these thoughts, agreed that the force of the planets acting upon people was not scientific but an otherworldly one, indicated by the alchemical axiom “As Above, So Below.” It stems from the previously widely held notion that everything in the heavens is pure, unchanging, and “good,” that the moral and spiritual impurity of people cannot help but be profoundly affected by these untainted perfect creations of God(s) in a way that instruments cannot detect.
Whether it’s daily blurb newspaper astrology or a complex mathematical analysis of a birth chart, the faith component is twofold: faith in the exertion of the planets, and faith that you or the astrologer is correct in their interpretation of where the planets land. The positions of the planets themselves do nothing; calculating those is as much an astronomical scientific pursuit. It’s believing in what they do being in those positions, and believing in the accuracy of the interpretation, that drives astrology.
I can’t imagine why an atheist would freely cast faith to such unpredictability. Unlike other pseudosciences like, say, Ufology, that bases itself in real scientific possibility that life on other planets exists (albeit extending this idea to ludicrous ends), astrology requires dedication to something extending beyond scientific parameters, a baseless faith in forces beyond our physical understanding.
I have no problem with astrologers considering their work a spiritual endeavour, but to claim it a science appears illogical even without testing.
