Because of its publication date Mitchell's article could only deal with Easton's, The Political System: An Inquiry into the State of Political Science (New York: Knopf, 1953)Google Scholar. Despite this Mitchell accurately foresaw many of the central features of Easton's subsequent work by noting that “the allocative framework is in many ways the analogue of the theories of income distribution and the allocation of resources in economics, and particularly neoclassical theory since there, too, the emphasis is upon the economy as a distributive process or system.” (page 79).

⁴ A Framework for Political Analysis (Englewood Cliffs, N.J.: Prentice-Hall, 1965), pp. xi–xii.Google Scholar (Hereinafter referred to as Framework.) Easton acknowledges the existence of some overlap with economics but insists that his main inspiration is drawn from other sources (p. xi).

⁵ These influences are cited by Easton in Framework (pp. xiiff.). To most readers, however, they may prove uninstructive since they presume some acquaintance with the personalities involved. James G. Miller who was associated with Easton in the Committee on Behavioral Science has been characterized as “an unabashed vitalist” thus lending at least indirect support to the physiological interpretation of Easton's approach. See Astin, John D., “Easton I and Easton II,” p. 727Google Scholar.

⁶ An indirect manner of achieving this result would be to assess the influence upon Easton's thought of Harold Lasswell and Talcott Parsons both of whom include characteristically economic notions in their overall approaches to the study of society.

⁷ It is interesting to note that Adam Smith's work has never been fully discussed from the point of view of systems theory. One partial exception is Louis Schneider's “Introduction” to a collection of readings from the works of the “Scottish Moralists” of the 18th century (i.e., Hume, Smith, Ferguson, Hutcheson, et al.). Schneider devotes several pages to a discussion of the “anticipations of functionalism” to be found in the works of these theorists. The Scottish Moralists On Human Nature and Society (Chicago: University of Chicago Press, 1967), pp. xlvii–lviGoogle Scholar. This neglect of Smith's work from the point of view of systems theory is especially surprising since as Parsons has noted “classical economics was the first instance in which a system of human activity was successfully analyzed as a dynamic system of inter-related variable elements.” ”The Rise and Decline of Economic Man,” Journal of General Education, 4 (1948–1950), 49Google Scholar. The prevailing opinion, however, seems to be that Smith's is not a systems model. For instance, Deutsch, Karl W. in The Nerves of Government (New York: Free Press, 1963)Google Scholar seems to exclude Smith from what he refers to as the “cybernetic” school of thought. The cybernetic model contains several elements which are characteristic of systems analysis, e.g., “self-monitoring, self-controlling, self-steering automatic processes” (p. 75), all of which are to be found in Smith's model. Deutsch classifies Smith as a “mechanist” (p. 29) a category which excludes such notions as “irreversible change, of growth, of evolution, of novelty and of purpose” (p. 27) most, if not all of which are also present in Smith's model.

Of course, whether the specified relations among variables actually obtain (i.e., have an empirical referent) is a distinct and separate question, which will remain outside the scope of this essay. On this point, however, we may note a difference between Easton and Smith. While Easton is primarily interested in articulating a framework for political analysis, Smith, on the other hand, advanced more than a framework for the analysis of economic systems and tried to explain why economic behavior occurs in the patterns that we observe.

Critics of Easton, however, have insisted that unless some numerical value can be given to the minimum level of support, the proposition that the system seeks to maintain support above a critical threshold is untestable.

It is seldom if ever implied that all variables under consideration are necessarily fixed. It is misleading to say that a given system is ‘in equilibrium’ … It would be preferable to say that a system is in equilibrium with respect to specific variables. The implication is clear: social scientists who use the concept of equilibrium need to make efforts to specify precisely what it is about the system they are assuming to remain unchanged.”

³⁵ It is clear, however, that Easton regards certain variables as homeostatic ones. For example, he states “The persistence of a given type of political system requires more than the presence of essential variables. They need to operate above a certain level. In other words, there is a critical range and if disturbances displace the system [sic] beyond it, the entire system will change its character.” Framework, p. 93.

³⁶ Systems Analysis, p. 157. For Easton's elaborate discussion of the concept of support see Part Three of the same work. By just referring to “support” I am greatly simplifying Easton's rich conception of support.

³⁷ Systems Analysis, p. 275. Easton is here primarily referring to the quid pro quo form of support (“specific support”). Easton is emphatic in his insistence that just specific support is insufficient to allow a system to persist. It needs to be supplemented by a “cushion” of diffuse support upon which the system may draw from time to time. Still, outputs are related to the level of diffuse support in at least two ways. First because in the long-run lack of desired outputs diminish the level of diffuse support (p. 273). Secondly, because the longer outputs satisfy demands the more likely it is that diffuse support will be generated (p. 275).

⁵⁰ For an overlapping analysis of the assumptions underlying Easton's conception of politics see William C. Mitchell's, “Politics as the Allocation of Values: A Critique,” pp. 79–90. He states. “Allocation theories in political science also make certain assumptions about the actors in a polity. These assumptions vary, but the dominant ones appear to conceive of political man as both essentially rational and motivated to maximize his returns, just as economic theory postulates an economic man.” (p. 81).

⁵¹ Yet, in a footnote, Easton seemingly denies that he is assuming maximizing behavior. He writes: “It may indeed appear from discussion of the ratio of demands to outputs that the member who is putting in support must, in some neo-Benthamite fashion, calculate the advantage to himself in the light of how the authorities act. If he fails to get the expected benefits, then he must conclude it is wiser to withhold support from these authorities. With the continuation of this process, he might take stock of his feelings toward the whole way of ordering political relationships and decide to withdraw support from the regime. Such a rational model of behavior might be useful if one wished to adopt the utilitarian assumptions that man knows his own interest and will pursue it. But for purposes of our analysis I have assumed no specific and dominant kind of motivation in political behavior.” (Systems Analysis, p. 409.) Easton thus distinguishes between the motivation and the behavior. He writes: “We do not need to make any monolithic or inflexible assumptions about the motivations of the authorities in the production of outputs. They may act to satisfy a need or desire for power, to fulfill a detached principle of right and wrong, to express a socialized sense of responsibility to the community at large, or to gain calculated advantage over their adversaries.” (Systems Analysis, p. 432.)

⁵² In Robert Merton's terminology this amounts to the distinction between “manifest” and “latent” functions. The former are consciously intended by the actors while the latter are the unintended consequences of the actors' behavior.

⁵³ Ernest Nagel insists that to be considered a teleological system any set of interdependent variables must not only obey the principle of equifinality but must include a compensating mechanism or negative feedback: “For example, I would not say that a simple pendulum which moves in such a way that it strives to achieve the lowest potential energy is a teleological system.

⁵⁹ Easton, , Framework, p. 100Google Scholar. Easton implies that a political Invisible Hand would seek to reestablish the status quo ante for the whole system once it is disturbed. As we have seen this is not necessarily the case.

⁶⁰ Scattered through the text of his various works are references to the political system as “a self-regulating, self-directing set of behaviors” (Framework, p. 128) or as “an open, self-regulating, and goal-setting system” (Systems Analysis, p. 479). Similarly, he explicitly includes the self-regulating mechanisms as part of his conception of system. “Every persisting system has homeostatic devices to help it cope with stress.” (Framework, p. 95.)

⁶¹ The distinction between the goals of individuals and the goals of the system is one which Easton makes but often forgets. He frequently speaks of the goals of the individual members within the system as if they were the same as the system's goal. (For an illustration see Systems Analysis, p. 20. For a discussion of this topic see Peter Leslie, “General Theory in Political Science: A Critique of Easton's Systems Analysis,” pp. 158–159 and Michael Evans, “Notes on David Easton's Model of the Political System,” p. 131.) This conflation of the two types of goals is, however, inconsistent with the following essential propositions of Easton's approach. Thus, Easton constantly (and literally) refers to the system's self-regulating, self-directing and goal-setting capacities. He emphasizes the existence of automatic regulative homeostatic devices. He insists that “Here as in other areas of our analysis, the subjective or rational intentions of the actors do not necessarily dictate the consequences of their behavior for the system.” (Systems Analysis, p. 433.) And, finally, he argues that the notion of “regulation” can be used meaningfully despite the absence of conscious and deliberate effort on the part of the actor(s) (Ibid., pp. 115–116). One possible solution to this inconsistency is provided by Easton when he notes that individuals can deliberately and rationally create regulative devices which will help keep the variables of a system within their respective critical ranges (Ibid., p. 116). In this sense there is no necessary contradiction. As we shall see, self-regulation does not occur within an institutional vacuum but requires a specific complex of institutions which may, of course, be deliberately created. Indeed, Adam Smith's market society had to be consciously fashioned after the mercantilist order was dismantled. But once the institutional framework of the market was created it automatically regulated the economic processes.

⁶² Systems Analysis, p. 364.

⁶³ Systems Analysis, pp. 363–364. Easton lists two other assumptions which parallel those of classical economics: a) the authorities are competent to achieve whatever goal they select, b) they have the resources to do so. These two assumptions parallel the conception of the economic actor as having the information, rationality and resources to select and implement his decisions.

⁷⁴ These three types of outlooks can be briefly described as follows: the parochial actor “expects nothing from the political system.” The subject actor is predominantly oriented towards the “outputs, administrative, or ‘down-ward flow’ side of the political system.” He still does not conceive of himself as an active participant. This is, in fact, the essential characteristic of the third type—the participant actor —who is oriented in an “activist” fashion towards “both the input and output aspects of the political system.” Almond, Gabriel and Verba, Sidney, The Civic Culture (Boston: Little, Brown, 1965), pp. 16–19Google Scholar. Since the authors are explicit in noting that the three types can exist simultaneously in a society the question of what percentage of actors has to be “participant” for Easton's model to function optimally has to be left to empirical investigation.

⁷⁵ Easton observes that peasant societies display “a kind of political impermeability, a long-suffering patience on the part of the general membership that leads to the acceptance of one's fate and either a complete absence of any thought of politicizing one's wants or an unquestioned stifling of any urge to do so.” Systems Analysis, p. 109.

⁷⁶ Nathan Rosenberg states “Atomistic competition, absence of collusion, and mobility of resources are not nearly sufficient to establish the linkage between unhampered pursuit of self-interest and social well-being. Smith himself clearly realized this. Indeed large portions of his Wealth of Nations are specifically devoted to analyzing the nature of the appropriate institutional framework.” “Some Institutional Aspects of the Wealth of Nations,” The Journal of Political Economy, 68 (Dec., 1960), 558–559Google Scholar. Mark Blaug concurs: “What distinguishes Smith's theory of economic development … from later and even from more recent efforts in the subject is a continuous harking back to the framework of social institutions that harness and channel pecuniary motives. So frequently accused of Harmonielehre, the vulgar doctrine of the spontaneous harmony of interests, Smith instead seems to be forever emphasizing that, the powerful motive of self-interest is only enlisted in the cause of the general welfare under definite institutional arrangements.” Economic Theory in Retrospect, p. 63.

⁹⁸ This formulation of free will within a context of apparent systemic necessity has a long and outstanding pedigree. For instance, Kant long ago noted that the study of history “if it examines the free exercise of the human will on a large scale, it will be able to discover a regular progression among freely willed actions.” He continues, “individual men and even entire nations little imagine that, while they are pursuing their own ends, each in his own way and often in opposition to others, they are unwittingly guided in their advance along a course intended by nature. They are unconsciously promoting an end which, even if they knew what it was would scarcely arouse their interests.” “Idea for a Universal History with a Cosmopolitan Purpose” in Kant's Political Writings, ed.
