American physiologist Lawrence Henderson's 1938 "box spring model" of the Pareto-Gibbs sociological extrapolation of the Le Chatelier principle of equilibrium restoration of the system after small modification to the system, which he defines as an equilibrium of forces. [9] |
“I wish to call your attention to-night to what I believe to be another universal law, a qualitative one and not a quantitative one. The chemists call it Le Chatelier’s Theorem. The physicists call it the the theorem of Maupertuis or the principle of least action. The biologists know it as the survival of the fittest, while the business man speaks of the law of supply and demand.”
“Equilibrium is a state such that if a small modification different from that which will otherwise occur is impressed upon a system, a reaction will at once appear tending toward the condition that would have existed if the modification had not been impresses.”
“Every system in chemical equilibrium, under influence of a change of every single one of the factors of equilibrium, undergoes a transformation in such direction that, if this transformation took place alone, it would produce a change in the opposite direction of the factor in question. The factors of equilibrium are temperature, pressure, and electromotive force, corresponding to three forms of energy: heat, electricity, and mechanical energy.”
“If any one of the factors determining the state of a physical system in equilibrium is altered by external action, the other factors will then change in such a way as to oppose the change in the first.”
“The treatment of equilibrium — which is referred to in note 4 — is logically of great significance. Pareto observes that the state of the social system is determined by its conditions. Therefore, if a small modification of the state of the system is imposed upon it, a reaction will take place and this will tend to restore the original state, very slightly modified by the experiment. This principle is well known, and thus the corresponding facts are familiar to everybody. Thus the disturbances produced by short wars, by epidemics that are not too severe, and by all kinds of lesser catastrophes ordinarily disappear and leave hardly a trace behind them. The case of physiological equilibrium is similar. In fact it is logically identical. These physiological phenomena belong to the same class as those inorganic processes that arise from similar disturbances of physical and chemical equilibrium. This is implied by the similarity of Pareto’s definition of equilibrium—a state such that if a small modification different from that which will otherwise occur is imposed upon a system, a reaction will at once appear, tending toward the conditions that would have existed in the modification had not been imposed—with the theorem of Le Chatelier in thermodynamics.”
(1) A ball which is in a cup, and struck a blow that is not too hard, will return to its original position;
(2) A candle flame which is deflected by a draft that is not too strong will resume its original form;
(3) A trout brook that is ‘fished out’ will, if carefully protected, regain its former population of fish;
(4) An infant, according to Hippocrates, after a disease that is not too sever will gain in weight until that weight is reached which is approximately what would have been reached if there had been no sickness.
“In both cases—Hippocratic analysis and Pareto’s equilibrium—there is the underlying theory that equilibrium, for instance, in a box spring; that a small modification leaves the forces substantially intact; and that the forces tend to reestablish the state that would have existed if no modification had occurred, just as a box spring which has been depressed when someone lies down on it resumes its original form when one gets up.”
In 1943, Samuelson assigned his first PhD student Lawrence Klein the project of generalizing the Le Chatelier principle to quadratic forms of statistical variances; Klein completed his PhD in economics at MIT in 1944. [11] The use of Le Chatelier’s principle in economics, after Samuelson (1947), has since been referred to by Yoshihiko Otani (1982), among others, as the “Le Chatelier-Samuelson principle”, as applicable to the theory of cost and production. [10]
“Equilibrium in society meant simply this: any small change in the state of the system would engender a reaction tending to restore the original state as unmodified as possible. Short wars, for example, or fairly light epidemics, or any of a number of small disasters, would disappear with scarcely a trace.”
“An interdisciplinary perspective of employee motivation is presented, based on the premise that the principles of natural science provide the fundamental basis for analogizing the operational similarities of physical and social productive systems. This concept is applied to motivation by observing that all productive systems-whether physical, organic or social-are input-output systems. The lowest common denominators in these systems are energy and mass. Le Chatelier's principle provides the universal environment for motivation. Thus, the transformation of energy in a given productive system represents the essence of motivation. The usefulness of analogizing the process of energy transformation in these two seemingly diverse systems can be seen by tracing the essential factors leading to efficient energy expenditure in physical systems and applying similar strategies to energy transformation in social systems. Such an approach will provide the manager with a concrete frame of reference from which to draw plausible remedies in solving the innumerable problems of efficient motivation and utilization of employee energies.”
