Astrology was studied at university (in Italy) until the 17th century; later, the Inquisition and the Roman Catholic Church ended its development. That is because divination would have been an obstacle to God's universal action, so nature and the planets could no longer serve as a link between man and their Creator.

Astronomy and astrology have maintained a common path for a long time; astrologers hailed Copernicus’ De Revolutionibus enthusiastically for simplifying astrological calculations. But as the age of the Enlightenment approached, reference books and encyclopaedias began to report the difference between astrologia naturalis, dealing with the scientific investigation of natural phenomena, and astrologia giudiziaria (judicial astrology), the art of forecasting events through planets and their relationship to the Earth. From that time on, astrology became a superstition and was overshadowed by astronomy in academic studies.
Nowadays, scientific thinking is based on an objective analysis of things as they are (or appear to be) through a theoretical statement that validates experimental facts or observations (or both). On the other hand, astrology considers the interaction between the phenomenon and the observer. From an astrological point of view, the whole universe and our awareness come together in the same process; that is why we cannot say there is a planetary influence, as some suggest. Relatively speaking, planets and stars exist separately from our consciousness and, as such, are the subject of scientific investigation. On the contrary, astrology undermines the assumption that the physical world exists independently of our observations (as suggested, for example, by some considerations of quantum mechanics). Consequently, astrological factors symbolise the reality we belong to, so our nature becomes highly readable via these same symbols.
Is reunification a possibility? Whether we like it or not, it is hoped that the scientific paradigm based on quantum mechanics will open a window into a new era of cooperation in the years to come.
