"We know and control physical forces only too well, biological forces tolerably well, and social forces not at all. If, therefore, we could have a well-developed science of social systems, it would be the way out of the chaos and impending destruction of the present world."

The Bertalanffian rationale for building a science of social systems is based on the assumption that social organizations are like living organisms in the sense that both display wholeness, interact with their environment, exhibit strategies of self-maintenance, and experience cycles of birth, growth, maturity and decline. However, the holistic relationship in the societal domain is quite different to the holistic feature of living beings which are the outcome of the evolutionary forces that have created unconsciously the terrestrial nature. The social organizations, as companies, corporations, clubs, governments, unions, leagues, etc., are systems that were designed and are maintained in operation purposefully through human actions organized by means of clever thinking. But societies as communities, cities and nations are in a large measure unconscious outcomes of social organizations interacting among themselves without being aware of what their dynamics affect the whole society. The whole of society exists 'ideally' for the sake of its members, while the humans do not live exclusively for the sake of their society, though every society is an entity constituted by and for individuals, but "man is not only a political creature; he is above all an individual". Then social organizations exist as a means to individual human ends but only for helping them to satisfy their needs, because each individual, having the possibility of creating an imagined world for him or her, makes everyone to believe that he or she has the inalienable right to the pursuit of self-fulfillment, and to assume that he or she may achieve an individual fulfillment on his or her own, without realizing in practice that they are social creatures who should not work simply for social systems though they must unavoidably work with these systems.

The Bertalanffy's science of social sciences faces also other difficulties: in the case of social, economic, political concerns to determine reliably what will be the outcome in the future of activities carried out by social entities that are constituted today and ought to be maintained continuously tomorrow and the day after; in social psychology, cultural anthropology, archeology and history the problem is to interpret rightly how could evolve the various interrelationships among existent societal factors, and consequently to comprehend the dynamics of historical events; for helping to recognize them as social achievements or to denounce them as failures and reject their results.

However, the main problem that faces the integration of a well-developed science of social systems -- related to sociology, economics and politics -- is the way every human may exercise his or her freedom when he or she has already decided to work with the social systems. Most people do recognize that one person's freedom tends to be another's restriction. Being impossible the existence of an absolutely free society it is necessary to constitute and maintain, inside every society and in the domain of every social system, the circumstances required for freedom to be achieved as a continuous process of compromise attained by means of conscious co-operation. A generalized co-operation among all the people involved and also co-operation between the generation alive at present and the generation of individuals that are not yet aware of the need of such co-operation, included the generations that presumably will try to survive and live during the next centuries and millennia. It makes necessary to examine co-operation through simulation.

When it is noticed that new and existing social systems are properly or wrongly modified by human actions, it confirms that each particular entity ough to be necessarily conceived, designed, maintained and improved as an 'open-system'. Then the general system insight in social sciences helps to encourage designers and managers to be increasingly aware of the emergent qualities of the organization that they intend to create and manage and also of the various ways every entity (system) may be affected by its environment. The utilization of this approach or view, developed by Katz and Kahn who adopted the Bertalanffy's model, may allow designers and managers, and also decision makers to observe how the social organization acts on its environment, how the environment acts on it, and how that interaction affects its growth and survival. Looking into an organization in this way, it is possible to determine how a particular social system, may or even should develop its self-regulation's capabilities for allowing the entity to adapt its functioning to new environmental happenings or how it will be advisable to reform patterns of human behavior and change the human environment which altogether would lead to organize consciously ways of interacting with the environment. Then, it would help:

• to search for laws to predict and control growth and competition among nations and the cancer-like growth of urban blight, congestion and pollution;
• to correct the goals of an organization in the course of satisfying its own urge for growth because it causes troubles to interests and values of its members
• to impede the expansion of a corporation when it is beyond the expertise of its management
• to make evident the inconvenience of expanding the program of that government which has no purpose other than bureaucratic empire building
• to reform patterns of human behavior by changing the human environment and/or the way the organization interacts with the environment.
