I'm basically agnostic about astrology, but I believe there's probably something to it. I think the only way to know is to get really into the subject and see if it seems to pan out. I think dismissing it out of principle is wrongheaded/narrow-minded thinking. As for horoscopes, I feel that a lot of them, like the ones in the newspaper for example, try to translate astrological principles way too specifically into everyday typical life patterns, to the point where the predictions become unlikely. They tend to give astrology a bad name IMO.
