Occultist: The issue of whether astrology is a science is easily settled: it is both an art and a science. The scientific components are the complicated mathematics and the astronomical knowledge needed to create an astrological chart. The art is in the synthesis of a multitude of factors and symbols into a coherent statement of their relevance to an individual. The reasoning in the occultist's argument is most vulnerable to criticism on the grounds that the argument ['denies the possibility that astrology involves components that are neither artistic nor scientific', 'presumes, without providing justification, that any science must involve complicated mathematics', 'incorrectly infers that a practice is a science merely from the fact that the practice has some scientific components', 'presumes, without providing justification, that any art must involve the synthesis of a multitude of factors and symbols']
