Here is my list of favorite astrology text and reference books: A to Z Horoscope Maker & Delineator, by Llewellyn George (several editions since 1910). (This is the only textbook which deals satisfactorily with progressions, gives anything like the correct orbs for progressed aspects, and correctly recognizes that transiting-to-natal aspects in transit horoscopes have the same orbs as aspects among natal planets.). Casting the Horoscope, by Alan Leo (8th ed. 1953 and others). The Astrologers' Handbook, F. Sakoian & L.S. Acker (1973); Transits Simplified, ditto, 1976 (gives particularly good interpretations of transiting to natal planets' aspects); The Astrology of Human Relationships, ditto, 1976 (gives very good interpretations of aspects between planets in different natal horoscopes in synastric comparisons).

The Witness of the Stars, by E.W. Bullinger (1967, originally 1893) (Important re Biblical and historical stellar astrology.). The Astrological Secrets of the Hebrew Sages, by Rabbi Joel C. Dobin (1983) (Very important re Old Testament astrology). The interpretations of astrological factors given in most of these textbooks are generally accurate, especially the interpretations of natal, synastric comparison, and transiting/ progressed aspects by F. Sakoian and L.S. Acker. However, the tendency has been for some published astrologers in recent decades to introduce many additional astrological factors into the interpretation of horoscopes, e.g. Arabian parts, asteroids, hypothetical trans-Plutonian planets, many fixed stars, comets, mid-points and aspects to them, nodes of planets' orbits, vertices, many minor aspects, etc., as fudges without any real scientific reasons or objective research whatsoever. Reinhold Ebertin's Hamburg, Germany, "School of Cosmobiology" has been a major offender in this respect. Sometimes this sort of thing has been done, probably by astrologers with badly afflicted Neptunes, under the guise of nebulously "adding a spiritual dimension to astrology"!. If taken seriously, such spurious or irrelevant additional factors would result in horoscope interpretation becoming impossibly complicated and incorrect. Unfortunately, the gross errors so introduced have become propagated through plagiarism by successive uncritical authors. This sort of thing has led to astrology acquiring a bad reputation amongst the scientific establishment. To prevent such errors, the principle of "Ockham's razor", also called the law of economy or parsimony or least action, attributed to the English philosopher William of Ockham or Occam (1285 -1349), that the fewest possible assumptions should be made in explaining something, should be rigorously applied to astrology, particularly research. Ockham's original theorem, in his Latin Scriptum in Librum Primum Sententiarum, Opera Theologica, I, p.74, was "non sunt multiplicanda entia praeter necessitatem" = "[hypothetical] entities are not to be multiplied beyond necessity", as applied originally to the logical analysis of theological dogma. This principle is central to the philosophy of science, and was used by the astronomer Galileo Galilei in defending the simplest hypothesis of the heavens. More recently (19th-20th centuries), the Austrian physicist- philosopher Ernst Mach enunciated it as requiring sciences to explain nature in the simplest and most economical conceptual formulations; and British mathematician -philosopher Bertrand Russell found it to be a very fruitful principle in logical analysis. It thus works hand-in-hand with scientific objectivity, and reproducibility of reported research results. However, this does not preclude a policy of "all things considered": reasonable propositions in astrology (as in other sciences) supported by evidence and/or logic, or at least not ruled out by evidence and/or logic, should be objectively analyzed. See, for example, An Introduction to Philosophical Analysis by John Hospers (1956), p.287, 363; and the Encyclopaedia Britannica articles on Ockham /Occam and his principle. Astrologers would do well to read up on the philosophy of science. John W.
