We have rationally explained the feasibility, limits and potentials of astrology. Now let’s address the question of its usefulness: Is it useful to know the inevitable and unchangeable future?
I think astrology is useful spiritually and materially. For the inner self, what could be more useful than a fuller understanding of life? For the outer self what could be more useful than more clearly understanding our talents and weaknesses? So, I think the only people who would insist that astrology is useless are those who don’t sufficiently value the truly important things in life: self-realization.
A valid argument might be: “An event destined to happen will happen if I know about it in advance or not. So there is no real value in learning of it beforehand.”
However, when something unexpected and unforeseen happens, the trauma or elation is extreme and unsettling. With foreknowledge of destined events we can prepare ourselves and greet the days of our life with more peace, calm and understanding. Is that not extremely valuable?
Also, we must question if the future is indeed totally inevitable. Although the movements of the planets are set in stone, I believe that their effects upon humanity are flexible and mutable to the force of will and of larger-scale, more powerful destinies.
Not all things are destined with equal strength. Some are more sure and others are less. When many powerful influences combine to the same end, it is more sure that this outcome cannot be changed. Good physicians know a terminal illness from a treatable one, and they know how to modify circumstances to treat the illness that can be healed. Similarly, good astrologers, whom we should heed, can tell definite from indefinite fates and understand how to advise us in appropriate ways to modify what we can in our destinies.
Before us, it was the Egyptians who mastered this science. We can see for sure that these masters considered the future changeable, because they created an elaborate system of medical astrology that they would use to cure diseases. We should not doubt that the original intention of astrology is to be proactive, not fatalistic.
Really, its silly to argue that foreknowledge is impossible or useless. By measuring the Sun’s movement through the zodiac we can all very easily know when winter and summer are coming. This foreknowledge is entirely useful, allowing us to prepare for the cold, heat, etc. Predicting human affairs is far more complex than predicting the general course of the year, so astrologers fail very often, which in turn causes the public to loose faith in the viability of astrology as a science. Similarly, it really is quite difficult to know the correct protective and corrective measures for a destined event. Astrologers therefore naturally fail to prevent or reduce an unwanted event quite easily and regularly, and this in turn causes the public to lose faith that it is even possible to alter the future. Without being naive to the human limitations of astrologers, we should not miss the opportunity to avail ourselves of the immensely positive potential of astrological prediction and remedial advice.
