(XII) HISTORY - 21ST CENTURY ASTROLOGY

In a similar fashion, that which characterizes astrological structure -- and distinguishes the structural modes of mathematics and language -- is its periodic nature (a point ignored by Serres' definition). The Zodiac is an annual cycle, Dominion is a daily cycle, planetary cycles have various periods (e.g., a month for the lunar cycle, twelve years for the cycle of Jupiter, thirty years for the cycle of Saturn, etc.).

The various qualities associated with the signs, planets and houses recur after a determinate period of time. Contrary to the movement of a pendulum, the cycle of respiration, or the rise and fall of the tides, all of which represent a simple to and fro, the astral cycle represents a true alternation of independent phases. It is this circularity which confers upon astral structures their homogeneity.

This cyclical structure is imprinted on the neural organization, which reproduces the periodic variations of the planets. Neuro-psychological integration of geo-solar rhythms translates itself into a continuous psychic stimulus -- astral incidence -- and into a structuring of the nervous system through pre-conscious mental states, which in turn give rise to psycho-mental representations.

The composite of a structural astrology lies in the assignment and coherent organization of these psychic "vectors" which underpin mental representations, in that they always result from the mediation between those inner states and the resistance to them in a human being's consciousness, stimulated by pre-conscious impulses and enervated by a contingent physical environment.
