Equally, the fact that there is, as yet, no western scientific theory that might encompass astrology doesn't undermine that, to those who have studied it, the ability to discern useful understanding of individual's personalities is real and discernable. I don't see fit to dismiss something simply because I don't understand how it can work (transistors must be a bugger for people of that persuasion) or because of the lack of credibility of its major proponents. keep to the Fen Causeway
With all of these things you have to be sure there's a What before you start asking about the How. Acupuncture built up a fairly solid body of evidence for itself over a long time, and eventually the medical profession grudgingly started to take it seriously.
With something like moon lore, there are two problems. The first is that if you look at crime records, hospital admission records and other hard data there doesn't seem to be any real effect. This could be because studies have asked the wrong questions, but the current state of what's known isn't encouraging.
But assuming there's a real effect - my problem with a statement like 'It words on the tides, so of course it works on humans' is that it's a pseudo-how.
It's fine for people who want to believe it, but if you accept it it closes down further curiosity.
Once you believe you know what's happening, you lose interest in anything that might challenge that - and might also deepen your understanding beyond the usual received explanations.
