“With the proper understanding of the economic system, the workers will soon find means to end that system, and to raise on its ruins a development of society having for its goal the benefit of the whole, instead of a part, of the community.”

It loses its essential properties when it is taken apart. The elements of a system may themselves be systems, and every system may be part of a larger system.

Human Nature and Social Theory (1969)
Context: One will be conducive to cooperation and solidarity another social structure to competition, suspiciousness, avarice; another to child-like receptiveness, another to destructive aggressiveness. All empirical forms or human needs and drives have to be understood as results of the social practice (in the last analysis based on the productive forces, class structure, etc., etc.) but they all have to fulfill the functions which are inherent in man’s nature in general, and that is to permit him to relate himself to others and share a common frame of reference, etc. The existential contradiction within man (to which I would now add also the contradiction between limitations which reality imposes on his life, and the virtually limitless imagination which his brain permits him to follow) is what I believe to be one of the motives of psychological and social dynamics. Man can never stand still. He must find solutions to this contradiction, and ever better solutions to the extent to which reality enables him.
The question then arises whether there is an optimal solution which can be inferred from man’s nature, and which constitutes a potential tendency in man. I believe that such optimal solutions can be inferred from the nature of man, and I have recently found it quite useful to think in terms of what in sociology and economy is now often called »system analysis«. One might start with the idea, in the first place, that human personality — just like society — is a system, that is to say, that each part depends on every other, and no part can be changed unless all or most other parts are also changed. A system is better than chaos. If a society system disintegrates or is destroyed by blows from the outside the society ends in chaos, and a completely new society is built upon its ruins, often using the elements of the destroyed system to build the new. That has happened many times in history. But, what also happens is that the society is not simply destroyed but that the system is changed, and a new system emerges which can be considered to be a transformation of the old one.

The Education of Henry Adams (1907)
Context: p>The result might have been stated in a mathematical formula as early as the time of Archimedes, six hundred years before Rome fell. The economic needs of a violently centralizing society forced the empire to enlarge its slave-system until the slave-system consumed itself and the empire too, leaving society no resource but further enlargement of its religious system in order to compensate for the losses and horrors of the failure. For a vicious circle, its mathematical completeness approached perfection. The dynamic law of attraction and reaction needed only a Newton to fix it in algebraic form.At last, in 410, Alaric sacked Rome, and the slave-ridden, agricultural, uncommercial Western Empire — the poorer and less Christianized half — went to pieces. </p
