The book cover still looks a little unassuming and dry, so that it may be possible to underestimate what a wealth of information there is for someone looking for a comprehensive introduction on how to interpret a natal chart (for predictive information, there is Robert Hand's compendium on transits - not actually possessing this, I do not know if it looks at progressions or not.)
It looks at the basics of the natal chart, which Hand calls 'a symbolic map of the psyche' - the Planets, Signs and houses, the major aspects and recommended orbs, but also introduces the reader to midpoints, the research findings of the Gauquelins, as well as discussing the possible relevance of the asteroids and fixed stars.
It might be deduced that this is not, then, a 'fuzzy' sort of a book - whilst not proclaiming that astrology is a 'science' as we know it, it does also wryly point out that the horoscope is rather more than just an inkblot, or sandbox, or crystal ball that simply allows the psychic impressions to flow. It does not decry the value of intuition, but points out that as astrology is more than just divination, then insights about character and telling of future should be gleaned from the horoscope, not from intuition.
Everything in the book is very reasoned, therefore. Perhaps, one of the things I also appreciated most about the book was the even-handed way it described the planets - in looking at the Sun and the Moon, for example, Hand borrowed from 'yin-yang' concepts - and genuinely does justice to both these celestial principles.
The book was written in the 70's, so there is nothing yet on Chiron and other centars, on Eris, Sedna and/or other newly-discovered planetary bodies. However, Hand does point out even from this vantage point that whilst asteroids, for example, may expand our understanding of the chart with newly-discovered factors, there is such a thing as 'information overload.' Therefore, there may be a need to ascertain which chart factors can be deemed as essential, and which not, as in fact he does in his suggestions for 'weighing' midpoints.
These points aside, this book still has to be a must-have for any new student to natal chart analysis.
