The science Nazis need to learn the definition of science. The word comes from a Latin verb, "scientia," meaning "to know." This word later evolved into "science" which means a body of knowledge. Astrology is a body of knowledge. Not only that, but prior to the 20th century and maybe a little bit into it, astrology was known as a science in that sense of the word. Today the meaning has devolved into "any subject that can be said to be understood by cause and effect." Any subject so understood is called an "applied science." Chemistry, biology, physics et al, are applied sciences. The word "science" also means for the most part, a particular method of determining facts. To use the word in a non scientific fashion, the late great chess champion Bobby Fischer looked at a particular position and said he had his victory technique "down to a science. Pry open the king rook file sac, sac, mate." He referred to science as a method that nearly always works. So like a lot of English words "science" has multiple meanings. Pace Mr. Dawkins, "God" is not one of them.
Astrology is not an applied science. It is a body of knowledge.
The Greeks didn't turn anything into anything. They learned astrology or proto-astrology from the Babylonians, and developed a system and that system was built on a world view that lasted for about 1500 years, far longer than the one currently in vogue. It was built on observation. There is, however, a logical system that contains astrology and the astrology itself was built on a logical foundation. Like us, they did the best they could with what they had.
The Enlightenment taught us to be condescending toward anything that came before and that is one of its most glaring flaws. Newton, a man who is as responsible for the current paradigm as anyone, credited his predecessors when he said that we stood on the shoulders of giants. Today we make fun of those giants as a sick way of patting ourselves on the back.
We just might want to consider that in the future, this Frankenstein created by the enlightenment might result in our descendants looking at things like black holes, dark energy, dark matter, and parallel universes as the products of superstition. I know they'll laugh themselves silly at the blind belief in man made global warming - possibly the greatest example of hubris in world history. .
