I keep hearing people say that comparing theology and science is like comparing astrology and astronomy. These are people who are attempting to snub theology. I just don't get it. Even if religions around the world are only complex memes evolving in the context of complex cultural dynamics someone could still benefit from studying what they have in common and where they differ. That is comparative religion 101 and falls under the heading Theology. It is certainly just as valid as Anthropology and Psychology as a field of research and endeavor. Also, as far as I can tell, there are many branches of astrology and while some are clearly moronic others attempt to use some relatively powerful tools to test some relatively interesting hypotheses about human nature. It seems like saying that comparing apples and oranges is like comparing plums and potatoes.
