Men think in terms of models. Their sense organs abstract the events which touch them; their memories store traces of these events as coded symbols; and they may recall them according to patterns which they learned earlier, or recombine them in patterns that are new. In all this, we may think of our thought as consisting of symbols which are put in relations or sequences according to operating rules. Both symbols and operating rules are acquired, in part directly from interaction with the outside world, and in part from elaboration of this material through internal recombination. Together, a set of symbols and a set of rules may constitute what we may call a calculus, a logic, a game or a model. Whatever we call it, it will have some structure, i.e., some pattern of distribution of relative discontinuities, and some “laws” of operation.
The substance of this paper was presented to the joint meeting of the Philosophy of Science Association and the American Association for the Advancement of Science at New York on December 30, 1949, and some passages have appeared in Goals for American Education, New York, Harper Brothers, 1950.

15 Somewhat differently phrased, a communications network is “a system of physical objects interacting with each other in such a manner that a change in the state of some elements is followed by a determinate pattern of changes in other related elements, in such a manner that the changes remain more or less localized and independent of the system from other sources” (Walter Pitts); a communications channel is a “physical system within which a pattern of change can be transmitted so that the properties of that pattern (or message) are more or less isolated from other changes in the system” (Norbert Wiener); “A state description is a specification of which of its possible states each element of the network is in. A message is any change in the state description of a network or part of it” (Pitts), or again somewhat differently stated, “a message is a reproducible pattern regularly followed by determinate processes depending on that pattern” (Wiener).

18 Rosenblueth-Wiener-Bigelow, op. cit., p. 19. A more refined definition of feedback, would put “output information” in place of “output energy,” in accordance with the distinction between “communications engineering” and “power engineering.” Cf. Wiener, Cybernetics, p. 50.
19 Rosenblueth-Wiener-Bigelow, op. cit. p. 18. There is also another kind of feedback, different from the negative feedback discussed in the text: “The feedback is … positive (if) the fraction of the output which re-enters the object has the same sign as the original input signal. Positive feedback adds to the input signals, it does not correct them….” Ibid., p. 19, see also Wiener, op. cit., pp. 113–136. Only self-correcting, i.e., negative, feedback is discussed in the present paper.

Irving Hallowell, “Sociopsychological Aspects of Acculturation,” in Linton, op. cit. p. 183; cf. in the same volume, Kluckhohn and Kelly, “The Concept of Culture,” pp. 84–86.
22 Rosenblueth-Wiener-Bigelow, op. cit., p. 18. “By behavior is meant any change of an entity with respect to its surrounds. … Accordingly, any modification of an object detectable externally, may be denoted as behavior.” Ibid.
23 Analytical understanding of a process need not diminish its sublimity, that is, its emotional impact on us in our experience of recognition. Faust becomes no more trivial by our knowledge of goal changing feedbacks than a sunrise becomes trivial by our knowledge of the laws of refraction.

50 In some calculating machines, and perhaps in the cells of the human brain there is some degree of reassignment of general elements to specific tasks or temporary subassemblies serving as “task forces.” In some societies, such as that of the Eciton army ants, there seems to be such a high degree of permanency of specialized function for each ant or class of ants, and so few degrees of freedom for an individual's choice of path that the entire column of ants may trap itself in a circular “suicide mill” where the path of each ant becomes determined by “the vector of the individual ant's centrifugal impulse to resume the march and the centripetal force of trophallaxis (food-exchange) which binds it to its group,” so that the ants continue circling until most of them are dead.
