Networks History Parts-Whole Analysis-Synthesis, Modular Decomposition 390 : , , , . [ 265,] First, the taking in of scattered particulars under one Idea, so that by precise definition, everyone understands what is being talked about ...Second, the analysis of the Idea into parts, by dividing it at the joints, naturally, not breaking any part as a bad carver might." [Plato, Phaedrus, 265d,e]

Networks History System 390 : , , , , [ 991] for it is necessary to explain it thus far: every diagram, and system of number, and every combination of harmony, and the agreement of the revolution of the stars must be made manifest as one through all to him who learns in the proper way, and will be made manifest if, as we say, a man learns aright by keeping his gaze on unity

Networks History -agasena ~120 X Nagasena: just as the King's chariot is neither its wheels nor its framework nor its axle nor its pole, nor its ropes, neither is man his matter, form, impressions, ideas, instincts or consciousness, nor the combination of these parts, nor does man exists outside them. . .

King Milinda of Bactriana: It is all these things, the wheels and the framework and the axle and the pole and the ropes,

in their interdependence that give the denomination chariot"

The Questions of King Milinda (Milinda Panha) The Chariot Story is quoted by BORGES J. L. 1962 Translations: Rhys T.W. 1890 and Horner I.B. 1969 in Labyrinths, New Directions, New York

Moreno Jacob 1934 Freud 1912 Freud asked him what he was doing Well, Dr. Freud, I start where you leave off. You meet people in the artificial setting of your office. I meet them on the street and in their homes, in their natural surroundings. You analyze their dreams. I give them the courage to dream again. You analyze and tear them apart. I let them act out their conflicting roles and help them to put the parts back together again.

Herbert Spencer 1880 Interdependence as Evolutionary Integration 1) Universality of natural law. The laws of nature applied without exception, to the organic realm as much as to the inorganic, and to the human mind as much as to society. 2) Evolution of Complexity. All structures in the universe develop from a simple, undifferentiated, homogeneity to a complex, differentiated, heterogeneity, a process of greater integration of the differentiated parts. A universal law, applying to the stars and the galaxies as much as to biological organisms, and to human social organization as much as to the human mind. 3) Individual and Social Evolution Increase of social aggregates accompanied by increase of the complexity of structures and Interdependence Creation of specialized social roles and institutions Spencer H. 1855-1880, A System of Synthetic Philosophy 10 volumes, Williams and Norgate, London
