I agree with him. Astrology was based on inferences from a huge number of observations over a period of thirty -five hundred years. A lot of intelligent people believed in it. Kepler made his living serving as a court astrologer. (The Catholic Church, BTW, was opposed to it because it deprives human beings of their freedom. In other words, dogma opposed science.) It wasn't until the telescope great increased the astronomical data base that astrology ceased to be plausible to educated people.
According to Behe, astrology was and is science.
