The simple answer is yes - and no. Astrology, like medicine, is an art based on a science. Scientific observations, measurements and calculations are used in astrology to generate the framework for symbolic patterns. These patterns reveal much about the way our world is constructed; they enable us to analyse, explain and predict social, political, emotional and other important characteristics of life on earth. A vast database of analystical techniques and interpretative commentary has been accumulated over the centuries, through the dedicated observations and practical applications of astrological practitioners. Modern astrologers have also made impressive contributions. The art of astrology lies at one level in the construction of accurate profiles of personality and relationship, through the skilled interpretation of symbolic patterns, and in mapping the general tendencies that present themselves over the course of our lives. Astrologers use scientific facts in the mapping of human consciousness and as keys to the understanding of experience. This is an interpretative process, which does not depend on accepting particular theories about how planets can affect us, or on whether they are a sort of synchronous clock ticking along with psychological and social factors on earth, or on some other causal process. The strength of astrology comes from the accumulated knowledge of centuries of research and observation. Combined with accurate mathematical and scientific data, today’s astrologers can use this established knowledge in the generation of valuable psychological, economic, or predictive profiles.
