Cosmos and Psyche is hefty book, and it presents many interesting ideas which I am sure many people — those with some prior astrological understanding and those without — will chew on for some time. From an astrological perspective, one of the more exciting things about the book could’ve, should’ve been new access to a comprehensive collection of historical data which could in turn be cross-referenced with astrological data. I have been using Passion of the Western Mind in this precisely this manner for years.
For example in the chronology after the epilogue in my copy of Passion, I noted on page 463 that in 1925, the year Yeat’s Vision, Thomas Dewey’s Experience and Nature, and Alfred Whitehead’s Science and the Modern World were published, Pluto stationed retrograde at 12 Cancer. I did this because I was examining relationships between specific degrees which appeared to be intensified by stations of the outer planets, eclipses and partile aspects between planets, and notable events in art and science. Many of the margins within my copy of the text itself are filled with such notations indicating possible correspondences (only in my case, I used exact aspects) between various historical periods and astrological significators, as are many other books I have studied, particularly history and biographies. This is typically how many modern western astrologers begin to study mundane astrology, before moving on to the complexity of ingress and lunation charts. And Tarnas’s Passion was a godsend in terms of this kind of work and study.
