In this occasion in finding the definite description made by ARISTOTELES of Greece on
the word SYSTEM to be
related to the total concept composites whole of soul and body, we must study in depth the reason of Medieval
European materialism that was strictly defined to select one of two extremes classified. As already has described
previously,
the trait of western astrology has been based on neither the materialism nor the spiritualism. As we saw the dual
characteristic of water with ice and water with vapor, the versatile characteristics of the western astrology will be
studied by new study of CHAOS physics that is explored in 1970s. 
This new physics has brought an extensive
development for the Meteorology and we may expect similar application on the versatile study on the western astrology
that will be done in the coming era of the Twenty-First Century.
We must examine in depth the system of astrology that was insufficiently explained in the undeveloped ages of
Europe found before and after the Medieval era. After the death of ALEXANDROS the Great in Babylonia in 323 BC
in his return trip of invasion to India, a leading staff of his regime established the kingdom of Ptolemaios in Alexandria
Egypt. The prosperity of astrological study in Egypt was ended by the Roman occupation of Egypt at the decade of
Cleopatra’s regime in the First Century AD found. We have learnt the studies of astrology in Egypt already. Among them, he description of TETRABIBLOS by Ptolemy
for the recommendation of twelve sign system of Grecian astronomy in place of Babylonian constellation and also the
description made by DOROTHEUS on the study of primitive house system,
those are marked evident.
During the whole long years in Europe, the people are disregarding the effort to study the total system of astrology but
eager to develop a specific part of individual tools in the art of prediction specified. Particularly in the Great Britain and the
continent of the United States of America, people are most eager to develop the partial tools of such as a specific part of
automobiles with rich style design. For instance, the students of astrology have enjoyed a computer tool in escaping from the
toilsome mathematical tasks but should have to accept an unreasonable system of sign barrier arrangements. Some one
employs a system with a cut off value at the end of sign and the others with 29 degrees and 60 seconds definition tentative settled.
As the problems encountered at the end of each sign in the astrology should be discussed with the similar understanding on
the problems found in the physics for two phases in the water with ice, this should be studied in new CHAOS physics of 1970s.
This author in the web has proposed a tentative solution to cut off less than 22 minutes in the astrological calculation on the
understanding of a practical technology involved.
