Addey's view was that constructs such as the twelvefold zodiac and house-systems were unable to evaluate many of the effects of cosmic periods. Twelvefold systems allow patterns of 2, 3, 4, 6 and 12 to be easily analyzed, but not cycles of 5, 7, 8, 9, 10, ll or greater than 12. The tools of astrology would have to be improved. He wrote, “We are all engaged upon the building of a science – a science which of course has practical application as an art. But what are the 'stones' with which this Science is to be built? This is an important question, for before any science can be truly unfolded, so as to realize its full potentialities, it must first be reduced to its fundamental concepts.”
