for long periods. John Addey had three children, Etain Addey (author, A Silent Joy), Tim Addey (author, The Seven Myths of the Soul, the Unfolding Wings – the Way of Perfection in the Platonic Tradition, and Beyond the Shadows – the Metaphysics of the Platonic Tradition) and Jane Addey. Astrological work According to Addley, astrology was not considered a scientific discipline because of the prejudices of orthodoxy, and a disinclination of astrologers to use the empiric and rational tools being refined by post-enlightenment scientists of all kinds. For this reason, Addey helped found the Astrological Association of Great Britain in 1958. He was the Association's first Secretary, and, on the resignation of its President Brigadier Roy Firebrace in 1961, became its second President, holding the office until 1973, at which point he became the Association's Patron. He edited the organisation's magazine, The Astrological Journal from 1962 to 1972, and was the prime mover in establishing the Association's annual conferences. He founded the Urania Trust as a registered education charity in 1970. Theory of "Harmonics" Addey's most important contribution to modern astrology was the Harmonic theory, which sought to put the understanding of astrological effects on a clear and rational footing. Starting from the great Platonic statement (Timaeus, 37d) that "Time is an image of eternity flowing according to number", Addey identified astrology as "the study of effects in the world of flux and change" in a 1958 article, 'The Search for a Scientific Starting Point'; and later articulated the fundamental law – "all astrological effects can be understood in terms of the harmonics of cosmic periods". In other words, the temporal world is only truly understood when it is seen as making manifest the great eternal ideas – Platonic Forms – in ordered cosmic periods. Reception of Addey's theory of Harmonics James Holden, in his History of Horoscopic Astrology, writes that Addey's theory of Harmonics "excited some enthusiasm when it was first announced, but it has not found favor with most astrologers", adding however that most horoscope programs can calculate harmonics if desired. Astrology Critics, reviewing Addey's Harmonics in Astrology (1976), writes that the book starts from the fact that even basic issues such as "which is the best system (Eastern or Western) in astrology, what is the correct house system, where is the cusp of a house, the delineations in 'good' and 'bad' aspects or 'good" and 'bad' signs."
