One more thing must be considered:
It has been thought that astrology is a science which, because it originated in an earlier time, could not develop. But in my view the situation is just the opposite. Astrology was an infinitely developed science in some extremely advanced civilization, but that civilization has been lost and only incomplete fragments of its astrology has remained in our hands.
Astrology is not a new science which needs to be developed, but a science which was at one time very advanced. Then the civilization which developed it was lost. Civilizations come and go every day: the fundamentals, the basic sayings and the basic principles of those things which have been developed by them, become lost.
Today, science is approaching the point where it will accept the thesis that life as a whole is affected by the movements of the stars.
