Traditional or Classical astrology works quite well for the most part but does not include the later discoveries of the astronomers. The invisible planets - Uranus, Neptune and Pluto address and represent aspects of modern human experience that did not exist in the classical period. There is a much better understanding of stellar mechanics and the behavior of comets and meteors and of the universe in general. Modern astrologers however, have become faddish and abandoned theory for a completely empirical approach with the notable exceptions of Ebertin, Johndro, and Barbault. The approach we take integrates modern discoveries in a classical context which extends traditional theory in light of modern scientific theories and discoveries.
