Astrology (contains a lot of Astronomy...)
Maimonides answered an inquiry concerning astrology, addressed to him from Marseille. He responded that man should believe only what can be supported either by rational proof, by the evidence of the senses, or by trustworthy authority. He affirms that he had studied astrology, and that it does not deserve to be described as a science. The supposition that the fate of a man could be dependent upon the constellations is ridiculed by him; he argues that such a theory would rob life of purpose, and would make man a slave of destiny. (See also fatalism, predestination.)
