Frases de Ludwig von Bertalanffy

Karl Ludwig von Bertalanffy foi um biólogo austríaco.Foi o criador da teoria geral dos sistemas, autor do livro de mesmo nome. Cidadão austríaco, desenvolveu seu trabalho científico na Áustria até 1948 quando se mudou para a América do Norte, trabalhando no Canadá e nos Estados Unidos.

Bertalanffy fez os seus estudos em biologia e interessou-se desde cedo pelos organismos e pelos problemas do crescimento.

Os seus trabalhos iniciais datam dos anos 20 e são sobre a abordagem orgânica. Com efeito, Bertalanffy não concordava com a visão cartesiana do universo. Colocou então uma abordagem orgânica da biologia e tentou fazer aceitar a ideia de que o organismo é um todo maior que a soma das suas partes.

Criticou a visão de que o mundo é dividido em diferentes áreas, como física, química, biologia, psicologia, etc. Ao contrário, sugeria que se deve estudar sistemas globalmente, de forma a envolver todas as suas interdependências, pois cada um dos elementos, ao serem reunidos para constituir uma unidade funcional maior, desenvolvem qualidades que não se encontram em seus componentes isolados.

“Todo organismo representa um sistema, com o qual nos referimos a um complexo de elementos em interação mútua. A partir desta afirmação óbvia devem seguir-se as limitações das concepções analíticas e sumativas. Primeiro, é impossível resolver completamente os fenômenos da vida em unidades elementares; para cada parte individual e cada evento individual depende não só das condições dentro de si mesmo, mas também, em maior ou menor grau, das condições dentro do todo, ou dentro de unidades superordenadas das quais ele faz parte. Portanto, o comportamento de uma parte isolada é, em geral, diferente do seu comportamento dentro do contexto do todo... Em segundo lugar, o todo real mostra propriedades que estão ausentes das suas partes isoladas.”

“Every organism represents a system, by which term we mean a complex of elements in mutual interaction. From this obvious statement the limitations of the analytical and summative conceptions must follow. First, it is impossible to resolve the phenomena of life completely into elementary units; for each individual part and each individual event depends not only on conditions within itself, but also to a greater or lesser extent on the conditions within the whole, or within superordinate units of which it is a part. Hence the behavior of an isolated part is, in general, different from its behavior within the context of the whole… Secondly, the actual whole shows properties that are absent from its isolated parts.”

“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.”

“Also the principle of stress, so often invoked in psychology, psychiatry, and psychosomatics, needs some reevaluation. As everything in the world, stress too is an ambivalent thing. Stress is not only a danger to life to be controlled and neutralized by adaptive mechanisms; it also creates higher life.”

“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.”

“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.”

“Biologically, life is not maintenance or restoration of equilibrium but is essentially maintenance of disequilibria, as the doctrine of the organism as open system reveals. Reaching equilibrium means death and consequent decay. Psychologically, behaviour not only tends to release tensions but also builds up tensions; if this stops, the patient is a decaying mental corpse in the same way a living organism becomes a body in decay when tensions and forces keeping it from equilibrium have stopped.”

“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.”

“Systems thinking plays a dominant role in a wide range of fields from industrial enterprise and armaments to esoteric topics of pure science. Innumerable publications, conferences, symposia and courses are devoted to it. Professions and jobs have appeared in recent years which, unknown a short while ago, go under names such as systems design, systems analysis, systems engineering and others.”

“Concepts like those of organization, wholeness, directiveness, teleology, control, self-regulation, differentiation, and the like are alien to conventional science. However, they pop up everywhere in the biological, behavioral, and social sciences and are, in fact, indispensable for dealing with living organisms or social groups. Thus, a basic problem posed to modem science is a general theory of organization. General Systems Theory is, in principle, capable of giving exact definitions for such concepts.”

“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.”

“From the methodological standpoint, however, we see that 'mechanism' and 'vitalism' by no means form the mutually exclusive disjunction they have been supposed to do. If a 'non-mechanist' wishes to deny the assumption of methodological mechanism that biological explanations must also be physico-chemical ones, it is obviously by no means intended that the required explanation must be 'vitalistic', i. e. involving the assumption that in living organisms factors analogous to psychical ones are 'at work'. A 'non-mechanistic' theory which is not all 'vitalistic' thus appears to be logically possible, and if we make a critical study of mechanism and vitalism this possibility will be seen to be of special importance.”

“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 [weltanschauliche], 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.”

“# General system theory in the narrower sense (G. S. T.), trying to derive from a general definition of “system” as complex of interacting components, concepts characteristic of organized wholes such as interaction, sum, mechanization, centralization, competition, finality, etc., and to apply them to concrete phenomena.
While systems theory in the broad sense has the character of a basic science, it has its correlate in applied science, sometimes subsumed under the general name of Systems Science.”

“If the variables are continuous, this definition [Ashby’s fundamental concept of machine] corresponds to the description of a dynamic system by a set of ordinary differential equations with time as the independent variable. However, such representation by differential equations is too restricted for a theory to include biological systems and calculating machines where discontinuities are ubiquitous.”

General System Theory (1968), 4. Advances in General Systems Theory

“General systems theory (in the narrow sense of the term) 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.”

“From the statements we have made, a stupendous perspective emerges, a vista towards a hitherto unsuspected unity of the conception of the world. Similar general principles have evolved everywhere, whether we are dealing with inanimate things, organisms, mental or social processes. What is the origin of these correspondences?
We answer this question by the claim for a new realm of science, which we call General System Theory. It is a logico-mathematical field, the subject matter of which is the formulation and derivation of those principles which hold for systems in general. A "system" can be defined as a complex of elements standing in interaction. There are general principles holding for systems, irrespective of the nature of the component elements and of the relations or forces between them.”
