Anatol Rapoport (May 22, 1911January 20, 2007) was a Russian-born American Jewish mathematical psychologist. He was one of the founders of the general systems theory. He also contributed to mathematical biology and to the mathematical modeling of social interaction and stochastic models of contagion.

Quotes[edit]

1940s[edit]

  • The behavior of two individuals, consisting of effort which results in output, is considered to be determined by a satisfaction function which depends on remuneration (receiving part of the output) and on the effort expended. The total output of the two individuals is not additive, that is, together they produce in general more than separately. Each individual behaves in a way which he considers will maximize his satisfaction function. Conditions are deduced for a certain relative equilibrium and for the stability of this equilibrium, i.e., conditions under which it will not “pay” the individual to decrease his efforts. In the absence of such conditions "exploitation" occurs which may or may not lead to total parasitism.

  • The first attempts to consider the behavior of so-called "random neural nets" in a systematic way have led to a series of problems concerned with relations between the "structure" and the "function" of such nets. The "structure" of a random net is not a clearly defined topological manifold such as could be used to describe a circuit with explicitly given connections. In a random neural net, one does not speak of "this" neuron synapsing on "that" one, but rather in terms of tendencies and probabilities associated with points or regions in the net.

  • Whether sociology can ever become a full-fledged "science" (a description of a class of events predictable on the basis of deductions from a constant ra~onale) depends on whether the terms which sociologists employ to describe events can be analyzed into quantifiable observables.

  • No map contains all the information about the territory it represents. The road map we get at the gasoline station may show all the roads in the state, but it will not as a rule show latitude and longitude. A physical map goes into details about the topography of a country but is indifferent to political boundaries. Furthermore, the scale of the map makes a big difference. The smaller the scale the less features will be shown.

  • A fundamental value in the scientific outlook is concern with the best available map of reality. The scientist will always seek a description of events which enables him to predict most by assuming least. He thus already prefers a particular form of behavior. If moralities are systems of preferences, here is at least one point at which science cannot be said to be completely without preferences. Science prefers good maps.

  • The predictions of physical theories for the most part concern situations where initial conditions can be precisely specified. If such initial conditions are not found in nature, they can be arranged. Such arrangements are considerably easier to realize with inanimate than with animate matter, because the properties of animate matter are much more sensitive to being tampered with than inanimate matter. In particular, living tissue in vitro may behave quite differently than in situ. Controlled biological experiments are, of course, possible, but they are more difficult and their scope is more limited than that of physical experiments. For this reason, biology has had to depend to a greater extent than physics on theories of larger speculative scope, in which reasoning by imaginative analogy plays a more important role.

  • There are different levels of organization in the occurrence of events. You cannot explain the events of one level in terms of the events of another. For example, you cannot explain life in terms of mechanical concepts, nor society in terms of individual psychology. Analysis can only take you down the scale of organization. It cannot reveal the workings of things on a higher level. To some extent the holistic philosophers are right.

  • It is the shortcomings of game theory (as originally formulated) which force the consideration of the role of ethics, of the dynamics of social structure, and of social structure and of individual psychology in situations of conflict.
    • p, vii (1974)
  • In a game, the potentialities and evaluations of alternative outcomes must be taken into account, if the reactions of the opponents to each other's moves are to moves are to be understood or described systematically.
    • p. 10
  • Conflict... is a theme that has occupied the thinking of man more than any other, save only God and love. In the vast output of discourse on the subject, conflict has been treated in every conceivable way. It has been treated descriptively, as in history and fiction; it has been treated in an aura of moral approval, as in epos; with implicit resignation, as in tragedy; with moral disapproval, as in pacifistic religions. There is a body of knowledge called military science, presumably concerned with strategies of armed conflict. There are innumerable handbooks, which teach how to play specific games of strategy. Psychoanalysts are investigating the genesis of "fight-like" situations within the individual, and social psychologists are doing the same on the level of groups and social classes.
    • p. 11
  • At present game theory has, in my opinion, two important uses, neither of them related to games nor to conflict directly. First, game theory stimulates us to think about conflict in a novel way. Second, game theory leads to some genuine impasses, that is, to situations where its axiomatic base is shown to be insufficient for dealing even theoretically with certain types of conflict situations... Thus, the impact is made on our thinking process themselves, rather than on the actual content of our knowledge.

  • We live in an age of belief-belief in the omnipotence of science. This belief is bolstered by the fact that the problems scientists are called on to solve are for the most part selected by the scientists themselves.
    • p. 108
  • A thorough understanding of game theory, should dim these greedy hopes. Knowledge of game theory does not make one a better card player, businessman or military strategist.
    • p. 108
  • Game theory applies to a very different type of conflict, now technically called a game. The well-known games such as poker, chess, ticktacktoe and so forth are games in the strict technical Bark and counterbark sense. But what makes parlor games games is not their entertainment value or detachment from real life.
    • p. 108
  • Although the drama of games of strategy is strongly linked with the psychological aspects of the conflict, game theory is not concerned with these aspects. Game theory, so to speak, plays the board. It is concerned only with the logical aspects of strategy.
    • p. 110
  • Whether game theory leads to clear-cut solutions, to vague solutions, or to impasses, it does achieve one thing. In bringing techniques of logical and mathematical analysis gives men an opportunity to bring conflicts up from the level of fights, where the intellect is beclouded by passions, to the level of games, where the intellect has a chance to operate.

  • Many psychologists, sociologists and especially anthropologists and psychiatrists raise serious objections against routine attempts to "extend the methods of the of the physical sciences" to the study of man. These objections cannot be dismissed simply on the grounds that they are not constructive; for inherent in the objections may well be a conviction that there can never be a "behavioral science" as scientists understand science. Whether there can be such a science or not will be decided neither by citing successful applications of "scientific method" to carefully circumscribed sectors of human behavior nor by pointing out what has not yet been done. Therefore on the question of whether a behavioral science can in principle be constructed, we shall take no sides. That some kinds of human behavior can be described and even predicted in terms of objectively verifiable and quantifiable data seems to us to have been established.

  • Crisis in its simplest terms is defined as an upset in a steady state... the habitual problem-solving activities are not adequate and do not rapidly lead to the previously achieved balance state.

  • The usefulness of the models in constructing a testable theory of the process is severely limited by the quickly increasing number of parameters which must be estimated in order to compare the predictions of the models with empirical results.
    • p. 150
  • Our first objective in undertaking the experimental program described here has been to gain some understanding of what goes on in long sequences of plays of Prisoner's Dilemma. We have attempted to gain this understanding by postulating a system going through a sequence of states and by attempting to formulate some mathematical models from which the dynamics of the system could be deduced. Once such a model is found, its parameters, properly interpreted, become the key terms in the emerging psychological theory. This strategy can be deemed successful, if the parameters so discovered are independent of the process itself, if they suggest further investigation, and if the further investigations, in turn, lead to a more inclusive theory.
    • p. 185
  • (Game theory is) essentially a structural theory. It uncovers the logical structure of a great variety of conflict situations and describes this structure in mathematical terms. Sometimes the logical structure of a conflict situation admits rational decisions; sometimes it does not.

  • We must admit that it is extremely difficult to formulate a theory sufficiently general to encompass all possible sufficient causes of wars. With regard to necessary causes, however,... it is weapons. Without weapons wars could not be fought. We are told that, deprived of weapons, people would still fight with sticks and stones. This, however, need not concern us. We are concerned not just with fighting but with the sort of mass insanity that can destroy the entire civilization, the product of millenia of accumulated effort, in a matter of hours. And this can be done only with real, up-to-date weapons, not sticks and stones.
  • [Education] seems to be the only hope: to spread enlightenment sufficiently wide so that people can no longer be manipulated to give consent to policies that will surely eventually lead to their own destruction.
  • The American Revolution was ignited by the slogan ‘no taxation without representation’, a slogan suggested by democratic ideals... Ought not the present day version of the old slogan be ‘No annihilation without representation?

  • The purpose of formulating [a] conflict as a game is not that of resolving the conflict by 'solving the game.' It is that of displaying the structure of the conflict and thereby exposing features of it that may be concealed by rhetoric. In particular, appreciation of the peculiar structure of some of the so-called mixed—motive conflicts represented nonzero-sum games may change the conflicting parties' perception of their situation.

Quotes about Anatol Rapoport[edit]

  • Anatol Rapoport is a pioneer and lead-figure of the systems sciences, studies in conflict & cooperation, and peace research. He is professor emeritus of Psychology and Mathematics at the University of Toronto, Canada... Rapoport has spearheaded many scientific innovations, including the application of mathematical methods, first to Biology and later to the Social Sciences. Moreover, he is one of the rare thinkers who have contributed significantly to "marrying" philosophy and science. The originality and rigor of his thinking make his theoretical oeuvre extraordinarily resourceful, as well as unique in its ethical substance and esthetical appeal. Rapoport operates from a multidimensional background of experience and studies (see the following C.V.), embodying a deep humanistic commitment (cf. Rapoport 1994), and a profoundly systemic thinking.
  • The social psychologist and game theorist Anatol Rapoport (creator of the winning Tit-for-Tat strategy in Robert Axelrod’s legendary prisoner’s dilemma tournament) once promulgated a list of rules for how to write a successful critical commentary on an opponent’s work. First, he said, you must attempt to re-express your opponent’s position so clearly, vividly and fairly that your opponent says “Thanks, I wish I’d thought of putting it that way.” Then, you should list any points of agreement (especially if they are not matters of general or widespread agreement), and third, you should mention anything you have learned from your opponent. Only then are you permitted to say so much as a word of rebuttal or criticism.
