The Old Philosopher of China has said that the virtue of everything is in its use. If Cosmic Symbolism cannot be applied to the practical ends of life it will not succeed in appealing to the average intellect, which sets for its standard the single test of utility. In these pages I have endeavoured to show that the Universe as Symbol is best studied in relation to its bearing on the common needs of humanity. I have also shown that Astrology is the only system of thought and practice that attempts the application. I propose now to examine the educational value of this study and its practical use in daily life, and thus to place it among the list of those subjects that have a serious claim to the consideration of enlightened people. Tracing our way through the Encyclopædia of knowledge we find that most of the deeper studies that engage the powers of men are valuable, not so much for the ends they lead to, as for the mental training obtained in their pursuit. It is one of the outstanding features of modern scientific methods that we are required to bring our theories into agreement with known facts. The facts themselves are often uninteresting and of small practical value, but they serve as landmarks by which to direct our course towards conclusions which in themselves are often valuable. It is thus with astronomy. The application of the _Principia_ or of the Laws of Kepler to the cosmos as we know it is an exercise requiring the greatest possible care, considerable mathematical ability, and the patience of a Prometheus. The bare facts of astronomy are not generally interesting. We are not solicitous of knowing in exactly how many days, hours, minutes and seconds the planet Jupiter completes its course about the Sun. What is of more practical interest to us as terrestrials is to know Jupiter’s relations to this world of ours, what it stands for in the economy of life, and what influence, if any, it exerts over us. Now Astrology, while employing all the elements of astronomy that have any certain foundation in fact, is calculated as a study to engage all the highest faculties of the human mind, while it brings to the results obtained the added virtue of utility.
