Ludwig von Bertalanffy on Science

"Game theory, analyzing in a novel mathematical framework, rational competition between two or more antagonists for maximum gain and minimum loss."

"There are quite a number of novel developments intended to meet the needs of a general theory of systems. We may enumerate them in brief survey:"

"or relational mathematics, including non-metrical fields such as network and graph theory."

"Bertalanffy Center for the Study of Systems Science BCSSS in Vienna."

"Information theory, introducing the concept of information as a quantity measurable by an expression isomorphic to negative entropy in physics, and developing the principles of its transmission."

"The general notion in communication theory is that of information. In many cases, the flow of information corresponds to a flow of energy, e.g. if light waves emitted by some objects reach the eye or a photoelectric cell, elicit some reaction of the organism or some machinery, and thus convey information."

"Science in the past , was dominated by one-sided empiricism. Only a collection of data and experiments were considered as being ‘scientific’ in biology ; forgetting that a mere accumulation of data, although steadily piling up, does not make a science."

"Classical science in its diverse disciplines, be it chemistry, biology, psychology or the social sciences, tried to isolate the elements of the observed universe - chemical compounds and enzymes, cells, elementary sensations, freely competing individuals, what not -- expecting that, by putting them together again, conceptually or experimentally, the whole or system - cell, mind, society - would result and be intelligible. Now we have learned that for an understanding not only the elements but their interrelations as well are required: say, the interplay of enzymes in a cell, of many mental processes conscious and unconscious, the structure and dynamics of social systems and the like."

"The system problem is essentially the problem of the limitation of analytical procedures in science. This used to be expressed by half-metaphysical statements, such as emergent evolution or ‘the whole is more than the sum of its parts,’ but has a clear operational meaning."

"We realize, however, that all scientific laws merely represent abstractions and idealizations expressing certain aspects of reality. Every science means a schematized picture of reality, in the sense that a certain conceptual construct is unequivocally related to certain features of order in reality;"

"Therefore, general systems theory should be, methodologically, an important means of controlling and instigating the transfer of principles from one field to another, and it will no longer be necessary to duplicate or triplicate the discovery of the same principles in different fields isolated from the other."

"Our conception is that of a theory about the system in an inertial state... if the organism is a system in an inertial state, as our law expresses it, the metabolic processes generally have to follow the established system; the ever progressing findings must replace the general expression of 'a system in an inertial state' by a more and more detailed knowing about the nature of this system and its chemical, osmotic, fermentive system conditions."

"Mechanism... provides us with no grasp of the specific characteristics of organisms, of the organization of organic processes among one another, of organic 'wholeness', of the problem of the origin of organic 'teleology', or of the historical character of organisms... We must therefore try to establish a new standpoint which — as opposed to mechanism — takes account of organic wholeness, but... treats it in a manner which admits of scientific investigation."

"Today our main problem is that of organized complexity. Concepts like those of organization, wholeness, directiveness, teleology, control, self-regulation, differentiation and the like are alien to conventional physics. However, they pop up everywhere in the biological, behavioural and social sciences, and are, in fact, indispensable for dealing with living organisms or social groups. Thus, a basic problem posed to modern science is a general theory of organization."

"Modern science is characterized by its ever-increasing specialization, necessitated by the enormous amount of data, the complexity of techniques and of theoretical structures within every field. Thus science is split into innumerable disciplines continually generating new subdisciplines. In consequence, the physicist, the biologist, the psychologist and the social scientist are, so to speak, encapsulated in their private universes, and it is difficult to get word from one cocoon to the other."

"There is a general tendency towards integration in the various sciences, natural and social. Such integration seems to be centered in a general theory of systems. Such theory may be an important means of aiming at exact theory in the nonphysical fields of science. Developing unifying principles running "vertically" through the universe of the individual sciences, this theory brings us nearer to the goal of the unity of sciences. This can lead to a much needed integration in scientific education."

"The science of life has nowadays to a certain extent become a crossroad, in which the contemporary intellectual developments converge. The biological theories have acquired a tremendous ideological , yes even public and political significance... The condition of biology, problematic in many respects, has led to the situation that the “philosophies of life” were until now by no means satisfactory from the scientific as much as the practical point of view; we see all the more clearly the importance of the theoretical clarification of biology."

"There are correspondences in the principles which govern the behavior of entities that are intrinsically widely different. These correspondences are due to the fact that they all can be considered, in certain aspects, "systems," that is, complexes of elements standing in interaction. that a general theory of systems would be a useful tool providing, on the one hand, models that can be used in, and transferred to, different fields, and safeguarding, on the other hand, from vague analogies which often have marred the progress in these fields."

"Thus, there exist models, principles, and laws that apply to generalized systems or their subclasses, irrespective of their particular kind, the nature of their component elements, and the relations or „forces‟ between them. It seems legitimate to ask for a theory, not of systems of a more or less special kind, but of universal principles applying to systems in general. In this way, we postulate a new discipline called General Systems Theory. Its subject matter is the formulation and derivation of those principles, which are valid for „systems‟ in general."

"General systems theory is a discipline concerned with the general properties and laws of “systems”. A system is defined as a complex of components in interaction, or by some similar proposition. Systems theory tries to develop those principles that apply to systems in general, irrespective of the nature of the system, of their components, and of the relations or “forces” between them. The system components need not even be material, as, for example, in the system analysis of a commercial enterprise where components such as buildings, machines, personnel, money and “good will” of customers enter."

"Our civilization seems to be suffering a second curse of Babel: Just as the human race builds a tower of knowledge that reaches to the heavens, we are stricken by a malady in which we find ourselves attempting to communicate with each other in countless tongues of scientific specialization... The only goal of science appeared to be analytical, i.e., the splitting up of reality into ever smaller units and the isolation of individual causal trains...We may state as characteristic of modern science that this scheme of isolable units acting in one-way causality has proven to be insufficient. Hence the appearance, in all fields of science, of notions like wholeness, holistic, organismic, gestalt, etc., which all signify that, in the last resort, we must think in terms of systems of elements in mutual interaction..."
