What's frustrating is throughout this whole discussion, I've received no reason why astrology is valid, no reason to believe in any of its propositions. All I've received is "you have to respect my right to believe in it." Which, although I think people that believe some of this stuff are committing ethical wrongs, I still respect your right to believe it.
I just want to challenge you to examine your beliefs and find a good reason to hold them. See if they stand up to the scrutiny of reason. A lot of the worlds' problem is that people take their beliefs for granted, and end up behaving in very bad ways based on those beliefs. The world, although not perfect, would be much better if people actually took a look and tried to find reason for what they believe in.
I criticize astrology because I can see its conclusions truly having an effect on the way its practitioners view other people, view the world, and what decisions they make in the world. When those conclusions, which are having a profound effect (if only on a handful of people) are based off faulty reasoning and unsound logic, it seems to be consequential and has the potential to be unjustly negative.
So just consider a reexamination of why you believe in astrology. "It works for me" really doesn't work, as it defies objectivity. "It feels right" doesn't work when determining the truthfulness of a belief either, as any belief can "feel right," and some beliefs have to be judged as false. They can't all be true (because then we'd have ones that were true, while the opposite is also true, and that wouldn't make any sense at all), so it's our job to find which ones are and aren't true, or if it's even possible to determine if a particular belief is possible to know.
Duty I agree with you that all beliefs are and should be held accountable to critical self-examination.
Now, if you'll allow me, I think this exact paragraph could equally apply to your need to criticize those who (for lack of a better word) "believe" in astrology.
By your own words you write that you feel the need to "criticize" astrology based on its "effects" on its practitioners. This sounds a lot like prostelytizing on your part. I don't see much difference in your admitted crusade to right the wrongs of astrology practioners/believers from past attempts to Christianize heathens, put native Americans in churches, or in general "illuminate" with the "light of reason" those who practice or believe inferior things.
Now, I think you are well intentioned and I dont think you mean any harm. But in reaching your conclusions you sound like you are making the assumption that what you believe is in someway superior to what others believe.
In particular, I strongly (but very respectfully) disagree with your statement that people who believe differently than you are committing an "ethical wrong." That is a pretty loaded statement and again I know you don't mean any harm but you should be careful with the characterizations. You seem marketedly at ease in calling other people wrong and declaring you are right. I am always unsettled by arguments of that sort.
Again, I have mixed feelings about astrology, and I don't know much about it. But I wouldn't feel comfortable explaining my beliefs on this thread, because you've already stated your conclusions, very strongly, that astrology is bunk. What effort would I or anyone ever take to explain something to you which you have already declared as "ethically wrong"?
In sum, I respect your belief that science and reason is the end-all-be-all of truth. But, I differ very strongly with the belief that that opinion is "right" and anything that differs is "wrong." Science, too, can stray towards fundamentalism; and while I'm all for differences of opinions, this world would be a much better place without the proseltyizing and "need to convert the heathens!" attitudes that is sadly a demon of Western culture and its 500 years of colonialism/White Man Burden endeavors.
I have relatives who worship fire (pretty badass in my opinion) and relatives who worship a statue of someone dying on a cross. i think differently than they, but hey -- we all have to reach our own conclusions about life. it's ok for people to think diffrently, especially in matters of spirituality and the values we use to make choices or plan our lives. We are all responsible for that.
Science used to say that blacks and women were inferior, and there used to be a lot of people who practiced "reason" saying some pretty silly things. This is all historical record. And has been conceded elsewhere there's a lot about life that science just can't explain. As you admit, science "knows its limits". So why the need to stray from them?
I hate having to sound like some stodgy ass all the time on these threads, I really have a keen sense of humor but it rarely comes out on these boards....SIGH!!
Anyway I'll see you around Duty, I ain't gonna say much more here...plus a nice glass of wine is calling my name.
