International Studies Quarterly (2006) 50, 3–25 Thucydides and Modern Realism JONATHAN MONTEN Georgetown University This paper makes two main arguments about the relationship between Thucydides, modern realism, and the key conceptual ideas they introduce to situate and explain international politics. First, Thucydides refutes the central claim underlying modern realist scholarship, that the sources of state behavior can be located not in the character of the primary political units but in the decentralized system or structure created by their interaction. Second, however, analyses that discuss Thucydides exclusively with respect to this ‘‘third-image’’ realism do not take into account the most important emendation made to political realism in the last half of the twentieth century, Kenneth Waltz’s Theory of International Politics. Waltz reformulates the theory of how anarchic political structures affect the behavior of their constituent units and suggests that the question posed by realismFand to be asked of ThucydidesFis not whether states behave according to the Athenian thesis or consistently observe the power-political laws of nature, but whether they suffer ‘‘costs’’ in terms of political autonomy, security, and cultural integrity if they do not. Many scholars are therefore incorrect to assume that demonstrating the importance of non-structural factors in The Peloponnesian War severs the connection between Thucydides and structural realism. Thucydides may in fact be a realist, but not for reasons conventionally assumed. Captivated by the methodological and substantive nature of Thucydides’ initial contention of a ‘‘truest cause’’ based on ‘‘the facts themselves,’’ modern realists and their critics have debated the appropriation of Thucydides as the founder of a continuous line of realist thought, with nothing less at stake than the historical credibility such a patron scholar entails. As Stephen Walt (2002) writes in a recent review of realist research, ‘‘the realist tradition has a distinguished lineage, including the works of Thucydides, Machiavelli, Hobbes, Friedrich Meinecke, Carr, and Morganthau.’’ Robert Gilpin (1986:306) writes that ‘‘in my judgment, there have been three great realist writers; it is difficult for me to conceive that anyone would deny them inclusion in the tradition. They are Thucydides, Machiavelli, and Carr.’’ And according to Robert Keohane (1986), ‘‘even as long ago as the time of Thucydides, political realism contained three key assumptions . . . [that] have furnished a usable interpretive framework for observers from Thucydides onward.’’ This paper will make two main arguments about the relationship between Thucydides, modern realism, and the key conceptual ideas they introduce to situate and explain international politics. First, Thucydides refutes what I argue is the Author’s note: The author would like to thank Gerald Mara, Daniel Nexon, the editors at ISQ, and three anonymous reviewers for their assistance with earlier drafts.

This ‘‘third-image’’ realism argues that the inherently conflictual and competitive character of international politics is attributable exclusively to the level of the international system, and not to the varying domestic-political characteristics of states. The ‘‘Athenian thesis,’’ the proxy for this style of thought in The Peloponnesian War, is in this regard a structural thesis; by abstracting from the properties of states, including, perhaps most importantly for Thucydides, the process of political–cultural contestation, it specifically rejects the impact of individuals, cultures, and institutions independent of the international circumstances in which they are situated. Through the competing logics framed by the Book I debate between Corinth and Athens over the rise of the Athenian empire, a central theme and the putatively ‘‘truest cause’’ of the war, Thucydides shows how the perspective of international politics offered by this style of realism fails to capture a significant dimension of what drives international politics more generally. In this regard, the contemporary literature that equates Thucydides with a modern realism understood in these terms neglects an important critique of realism offered by his narrative of the Peloponnesian War. Second, however, analyses that discuss Thucydides exclusively with respect to this ‘‘third-image’’ realism are inadequate in light of the most important emendation made to political realism in the last half of the twentieth century, Kenneth Waltz’s Theory of International Politics (1979). In contrast to the determinate predictions about state behavior derived from third-image realism, Waltz reformulates the nature of how an anarchic political structure affects the behavior of its constituent units. Waltz suggests that the question posed by modern realismFand to be asked of ThucydidesFis not whether states behave according to Athenian thesis or consistently observe the power-political laws of nature, but do they suffer ‘‘costs’’ in terms of political autonomy, security, and cultural integrity if they do not. Otherwise persuasive critiques of realist claims to The Peloponnesian War often overlook this second dimension; Thucydides may in fact be a realist, but for reasons not captured within the terms of the current debate. Thucydides and Modern Realism The uncritical induction of Thucydides into the political realist tradition appears to be based on a series of misunderstandings about the manner in which Thucydides portrays the Peloponnesian War, errors that have not gone unnoticed in the discipline. According to David Welch (2003), for example, there is an ‘‘utter lack of empirical support’’ for key realist arguments in the text and that ‘‘identifying realist ‘misreadings’ of Thucydides has become something of a cottage industry.’’1 Similarly, Laurie Johnson Bagby (1994) recommends that Thucydides can ‘‘guide us in our studies beyond realismFand especially beyond neorealism.’’ These authors are correct that Thucydides and modern realism are at times engaged in very different kinds of projects, and a ‘‘Thucydidean’’ reading of any modern realist work must first address if there is in fact any basis for comparison. Many scholars equate Thucydides with the Athenian perspective presented most notoriously at the Conference of the Peloponnesian League at Sparta in Book I and at Melos in Book V (Waltz 1954:159; Keohane and Nye 1977:42; Morgenthau 1954:38; Waltz 1979:127, 186–187; Doyle 1990; Frankel 1996). In fact, Thucydides presents a variety of perspectives through a variety of actors, and when he interrupts the narrative with his own voice, for example when commenting on the postPericles political competition that took place in Athens or on the Corcyran stasis, his 1 Examples of this ‘‘cottage industry’’ include Garst (1989), Ahrensdorf (1997), Lebow (2001), and Thomas (2005). JONATHAN MONTEN 5 comments, as will be shown, are often indirectly critical of certain realist propositions. The Athenian thesis is the clearest representation of realist thought in The Peloponnesian War, and in portraying the history of a system of independent citystates interacting in the absence of an overarching political authority, ThucydidesFthrough actors such as the Corcyrans, the Mytelineans, and most consistently the AtheniansFintroduces elements of what would become known as the realpolitik tradition. Nonetheless, Thucydides presents this foreshadowing of modern realism as one of many orientations toward international politics. In addition, Kenneth Waltz’s Theory of International Politics, and the school of realist thought that has developed around it, engages in the hypothesizing of positive, explanatory propositions about international politics. As a social scientific theory, modern realism seeks to specify the causal conditions under which certain political outcomes can be expected, and systematically tests these propositions against empirical evidence. But despite his self-professed desire to describe events that ‘‘in accordance with human nature will recur in similar or comparable ways’’ (1.22),2 Thucydides’ political history is not primarily interested in drawing regularized, causal connections between phenomena in the manner of a covering law. As Welch (2003:303) argues, Thucydides ‘‘does not offer us anything that we could immediately recognize as a theory.’’ Many contemporary authors treat the text of The Peloponnesian War either as a source of political ideas from which one might infer a series of falsifiable, positivist hypotheses, or as a case study or pure historical account against which to test various realist propositions regarding, for example, conditions under which states balance or bandwagon against power, or the conditions under which transitions in power lead to war (Gilpin 1988:591; Lebow and Strauss 1991; Copeland 2000). However, there is a basis for comparison in at least two respects. First, Thucydides portrays himself as practicing a certain methodological realism, or a procedural focus on facts and observational accuracy.3 Post-World War II realism, crafted in deliberate counterpoint to the ‘‘utopianism’’ of the interwar period, advanced itself as the science of international politics, grounded in positive science over normative idealism. E.H. Carr (1939:10) described this realist turn as the natural evolution of international relations as a social science; realism ‘‘represented a reaction against the wish-dreams of the initial stage . . . placing its emphasis on the acceptance of facts and on the analysis of their causes and consequences.’’ Thucydides similarly presents his history in contrast to previous works, suggesting that what he foregoes in style he gains in the accuracy of his account, not coincidentally lending his text the attendant moral authority or credibility of impartially portraying the ‘‘real’’ world. Thucydides explicitly portrays himself in contrast not to utopians, but to poets, who ‘‘embellish with their exaggerations . . . in versions that cannot be checked and for the most part have forfeited any credibility over time a patriotic fiction’’ (1.21). In contrast, his account, ‘‘by avoiding patriotic storytelling, will perhaps seem less enjoyable for listening. Yet if they are judged useful by any who wish to look at the truth about both past events and those that at some future time, in accordance with human nature, will recur in similar or comparable ways, will suffice.’’ For example, immediately before this methodological statement, Thucydides describes how the Athenians misunderstand key elements of their own history through the uncritical acceptance of erroneous facts regarding the overthrow of Peisistratos, an event he describes in greater detail in Book VI. Thucydides’ interest in procedural realism is 2 All quotations are drawn from Thucydides, translated by Lattimore (1998). Gregory Crane (1998) identifies four characteristics common to all realisms: a procedural, a paradigmatic, a scientific, and an ideological. For the purposes of this paper, I focus on the first and second. Gerald Mara also suggests a distinction within realism between ‘‘accuracy,’’ or factual veracity, and ‘‘precision,’’ or explanatory power, which closely corresponds to Crane’s procedural and paradigmatic. Conversation with author, March 2005. 3 6 Thucydides and Modern Realism also illustrated by the importance of the Corcyran stasis in his narration of the war, during which one of the most insidious signs of cultural disintegration was the inversion of language and meaning. Under the conditions of civil war, Corcyra, and later the cities to which civil war spread, underwent a ‘‘revolution in thinking . . . in self-justification men inverted the usual verbal evaluations of actions’’ (3.82). Gregory Crane (1998) usefully points out that the inability of words to retain stable meanings undermines the conditions necessary for historians like Thucydides to operate, as well as the basis of objective, factual accounts.4 Whether Thucydides’ claim to this procedural or scientific realism, and the moral authority that follows from the perception of impartiality, is for instrumental or artistic purposes, The Peloponnesian War has nonetheless, according to Steven Lattimore (1998), been ‘‘long valued for setting an unprecedented standard of objectivity and consequent accuracy.’’5 Second, Thucydides, Waltz, and other modern realists all advance, at minimum, a certain logic of political relations; they identify the central issues and dynamics at stake in international politics, and specifically the character and qualities of political life between autonomous political–cultural groups interacting in the absence of an overarching, centralized political sovereign or public agent with a legitimate monopolization on the use of force. The argument that there are, according to Welch (2003:308), ‘‘no models in Thucydides’’ follows from an overly narrow understanding of what constitutes a useful theoretical model of political behavior. Crane (1998:56) describes a ‘‘paradigm’’ as a conceptual scheme that ‘‘drags new phenomena into the light [while] pushing other phenomena back into the shadows.’’ Similarly, Waltz (1979:8) suggests that ‘‘a theory indicates that some factors are more important than others and specifies relations among them.’’6 Thucydides is in this regard loosely paradigmatic or theoretical; although not formulating strict, falsifiable hypotheses that can be rigorously tested against competing explanations, he presents a historical narrative within a conceptual scheme, privileging certain themes while deliberately reducing others. The Peloponnesian War can therefore be used as a source of competing ideas about politics. A basis of comparison is not to test realist hypotheses against empirical evidence, and in this case the ‘‘observation’’ of the events surrounding the war, but to situate facts and events within a broader perspective, and to delineate the key conceptual issues at stake between modern structural realism and the historical narrative of the Peloponnesian war as presented by Thucydides. The Third Image and the Sources of Athenian Imperialism The central analytical claim of modern realism, with the exception of the distinction to be drawn later in this paper, is that the sources of state behavior can be located not in the character of the primary political units, but in the decentralized system created by their interaction. Modern realism is positional or situational in logic: independent of the character or properties of political agents, under conditions of anarchy they are uniformly compelled to act in terms of necessity and the pursuit of power-political advantage. It is rooted in the concept of the Primat der Aussenpolitik, or the ‘‘primacy of foreign policy,’’ a term that has come to have two meanings. Originally, it referred to the idea that the international system affected the devel- 4 Interestingly, Crane’s translation of 3.82 is that ‘‘words had to change their ordinary meaning,’’ suggesting that it was language itself, and not just specific words relating to the evaluation of behavior, that became subverted in Corcyra. The argument about Thucydides presenting himself as a ‘‘scientific realist’’ seems to hold under either translation, although somewhat better under Crane’s. 5 Whether Thucydides actually conforms to this standard of factual accuracy is not at issue here, only the perception and subsequent appropriation of Thucydides as a ‘‘procedural realist.’’ 6 See also Waltz (1988:615–628). JONATHAN MONTEN 7 opment of a state’s domestic institutions.7 The second, and the more relevant meaning to this discussion, refers to the line of argument that states conduct foreign policy for ‘‘strategic’’ reasons, or as a consequence of the pressures of the international system; international politics is conceived of as apart from, and not an extension of, domestic politics. Whereas advocates of Primat der Aussenpolitik argue that state behavior is determined by external considerations of material power, advocates of what Fareed Zakaria (1992) labels a competing Innenpolitik school argue that foreign policy can be explained by factors internal to a state, and traditionally, but not limited to, its economic and political organization.8 In post-World War II realism, this distinction has largely been reframed in terms of the levels of analyses, or ‘‘images,’’ at which state behavior can be explained. Originally a term used as a taxonomy to classify and organize different arguments on the sources of war, Kenneth Waltz’s (1954) introduction of three imagesFthe individual, the state, and the international systemFhas become a framework with which to explain international politics more broadly.9 This approach has since become almost correlational in logic: a ‘‘third image’’ approachFor one that locates the source of state behavior in the international systemFargues that an international environment characterized by anarchy encourages states with varying domestic properties to behave in similar ways when external conditions are held constant, whereas states whose domestic conditions are similar will behave differently when external conditions vary. Alternatively, a ‘‘second-image’’ approachF one that locates the source of state behavior in the stateFexpects the opposite that: state behavior corresponds more with variation at the domestic than the international level. This broad division in contemporary international relations theory is strikingly anticipated in the debate between Athens and Corinth at the Conference of the Peloponnesian League at Sparta over the sources of Athenian imperialism (1.67– 1.88). Corinthian and Athenian representatives advance competing propositions about Athenian behavior specifically, and the determinants of intercity relations more generally. Athenian Aussenpolitikers argue that Athenian imperial behavior is, given certain constants in human nature, a function of its relative material power position, whereas Corinthian Innenpolikers argue that Athens’ empire is a consequence of factors unique to Athens itself, and specifically its vibrant and innovative political culture and institutions. At stake in this debate is not just the content or nature of Athenian political culture, but also the causal impact of a second-image argument relative to the effects of the international system. Because this debate corresponds so closely to the levels-of-analysis distinction drawn between modern realism and domestic-political theories, it is a useful place to begin to evaluate these two competing schools in terms of Thucydides’ approach to politics. The remainder of this section will identify the central assumptions of modern realism, discuss how they relate to the view of international politics first articulated by Athens at the Peloponnesian Congress in Book I, and show how a competing domestic-political theory centered around political culture and institutions presented by CorinthFand interestingly, presupposed in Pericles’ major speechesFundermines Athenian, third-image realism. 7 Aspects of Thucydides’ treatment of Corcyra and Athens, cities whose political communities were undermined when the competitive, self-aggrandizing character of their foreign policies began to influence domestic political competition, represent this family of realist theory. See Thucydides at 2.65 and 3.82. Modern parallels to this causal logic are surveyed in Gourevitch (1978:881–912). 8 A brief history of these two schools as they relate to contemporary debates can be found in Zakaria (1992). 9 The term ‘‘image’’ was introduced in Waltz (1954). For a different conceptualization of the levels of analyses at which state behavior can be understood, see Jervis (1976). 8 Thucydides and Modern Realism Realist Assumptions What constitute the fundamental assumptions of the modern realist paradigm, and how do they relate to the realist worldview articulated by Athens? While there are a number of iterations (Keohane 1986; Mearsheimer 2001; Walt 2002), realist theories tend to share three assumptions regarding the nature of international-political life. First, the international system is characterized by anarchy, in that there is no centralized, sovereign political authority or public agent that commands a monopoly on the legitimate use of force. Anarchy is in this sense an ordering principle, and not a description of the quality of international life as chaotic or inherently conflictual. Second, states are the primary actors in international politics, and can be regarded as purposive, unitary actors. Thucydides often relies on this assumption as a simplifying device, referring, for example, to Athenians, Melians, or Spartans as coherent, unitary actors in the international system. Although the primary political unit may change over time, according to Robert Gilpin (1986), the ‘‘essence of social reality is the group.’’ Third, states are rationally self-interested and generally seek to survive as independent political entities. Political units select strategies that they believe maximize their interests, and at a minimum seek to survive, generally defined in terms of their territorial integrity and the autonomy of their domestic political order and political culture. Many discussions of Thucydides and modern realism seem to begin by evaluating the extent to which the History accepts or problemetizes these initial assumptions. Crane (1998) finds that central realist assumptions can be traced to Thucydides, which in his particular iteration includes anarchy, the importance of organized social groups, rationality, the drive to maximize power, and the inherent amorality of international politics. Alternatively, Johnson (1994) argues that the prominence of individuals in the narrative and speeches challenges realist assumptions of state centricity, while Peter Ahrensdorf (1997) contests whether the Hellenic international system is in fact anarchic, given the Greeks could not in principle know if there is a divinely enforced moral order. The positing of rationality does not correspond with Stephen Forde’s (1995) reading of the behavior of a number of actors in the History; at some level, states like Melos and Sparta act on the basis of a specific conception of justice or piety, and do not respond rationally to international conditions. According to Gerald Mara, Thucydides shows how Greek political groups, and the cultures that underlie them, are not immutably coherent but are fluid: they can both integrate (a goal pursued, e.g., by Syracuse’s Hermokrates with respect to Sicily) and disintegrate (e.g., Corcyra).10 By using these premises as a dimension of comparison with Thucydides, these authors misunderstand the nature of modern, narrowly analytical assumptions. Many realist assumptions are of the positivist ‘‘as if ’’ variety; they are theoretical constructs, intended to be analytically useful, not descriptively accurate (Friedman 1953; Waltz 1979).11 The purpose of assumptions regarding anarchy, the primacy of states, and self-interested rationality is similar to that of assumptions made by modern economics regarding utility-maximizing individualsFacknowledged to be factually inaccurate, but intentionally simplifying for the purpose of constructing theories with some explanatory and predictive power. More significant is the political logic advanced by the terms of the theory, and its ability to situate or give perspective to important events and developments in the History. From these assumptions, realism derives certain broad expectations regarding state behavior. Because states interact in the absence of an overarching, public authority with a monopoly on the use of legitimate violence to regulate disputes and enforce decisions, states must rely on their own capabilities to achieve their 10 11 Conversation with author, November 2003. Mearsheimer (2001), in contrast, defends realist assumptions as descriptively accurate. JONATHAN MONTEN 9 interests and objectives, however defined. Without the presence of a public authority, private force is the ultimate arbiter of disputes; according to Waltz (1954:238), ‘‘force is a means of achieving the external ends of states because their exists no consistent, reliable process of reconciling the conflicts of interest that inevitably arise among similar units in a condition of anarchy.’’ Although states are not engaged in constant warfare, the possibility that force might be used against their interests compels them to compete for security, and to be concerned for their power position relative to other states. Normative or cultural interests are subordinate to security, because the continued autonomy of the political entity is thought to be a precondition for these other political objectives. And because states value their relative position, political cooperation is difficult to achieve independent of an underlying distribution of power and interests. These power-political imperatives are incumbent upon states under anarchy; states must provide for their own interests, and thus are of necessity compelled to act on the basis of advantage and expedience. But as games like the Prisoner’s Dilemma and the Stag Hunt have demonstrated, the pursuit of individually rational choices can result in collectively suboptimal outcomes. Political units, whether individuals in the state of nature or states under conditions of anarchy, must behave as if other actors are potentially predatory or irrational; as Waltz (1954:169) wrote, ‘‘if harmony is to exist in anarchy, not only must I be perfectly rational but I must be able to assume that everyone else is too . . . to attempt to act on a rational calculation without allowing [for irrational acts] may lead to my own undoing.’’ The key concept advanced by third-image realism is thus that insecurity and competition are generated not by properties of the units, but in the situation they collectively face. Concern for relative position, security, and power is a rational response to anarchy; independent of their unique domestic characteristics, states are under uniformly intense systemic pressure to act on the basis of interest and necessity, to engage in security competition, and to attempt to redress imbalances, or anticipate potential imbalances, in their relative power position. As has already been observed, realism’s central analytical claim about the insecurity and fear generated by a system of autonomous, competing political units under anarchy finds apparent expression in Thucydides’ statement on the ‘‘truest cause’’ of the Peloponnesian War: the growth of Athenian power necessarily engendered fear and insecurity in Sparta, compelling Sparta to initiate a war. Although Thucydides only occasionally speaks directly in his own name, his account of the ‘‘truest cause’’ at 1.28 is strikingly structural. Following the Conference of Peloponnesian allies in Book I, he extends this explanation by stating that ‘‘the Lacedaemonians voted that the treaty had been broken and that they must go to war not so much because they were persuaded by the arguments of their allies because they feared further increase in the power of the Athenians, seeing the greater part of Hellas already under their control’’ (1.88). Athenian statements of strength at the Peloponnesian Congress, intended to dissuade Sparta, also illustrate the inadvertent nature of causal effects located at the third image: by highlighting the disparity of power between Athens and Sparta, the Athenian remarks only contributed to Spartan fear and insecurity, ultimately rendering Athens less secure and making conflict more likely.12 12 It could be argued that Sparta’s fear was subjective, and did not necessarily follow from the structural condition of rising Athenian power. The key question, to be framed in the following discussion of realism, is whether states with varying domestic attributes (or varying in those factors that bear on perception) would have responded to identical structural conditions identically. At the very least, Athens contributed to this perception with the remarks of its representatives at the Spartan conference. 10 Thucydides and Modern Realism The Athenian Thesis The modern realist view is most approximated in Thucydides’ text by what Clifford Orwin (1994) has labeled the ‘‘Athenian thesis,’’ a paradigm that closely corresponds to third-image realism. Although specifically addressing questions of justice and the sources of its empire, Athens presents a more general theory of state behavior centered around anarchy and relative material power position in three places: the Peloponnesian Congress in Book I, the Melian Dialogue in Book V, and the Athenian speech to the Camarinaeans in Book VI. The Athenian representatives at Sparta give a positional account of their empire; Athens’ imperial behavior was compelled by the insecurities and necessities generated by international anarchy, and not characteristics unique to Athens as a political entity. Initially compelled to succeed Sparta in leading the Hellenes against the Persian threat, Athens’ transition from the war-time leadership of the Delian league to coercive empire was ‘‘compelled from the first by the situation itself to expand the empire to its present state, especially out of fear, then prestige, then self-interest’’ (1.75, italics mine). Once the tribute system of the empire had become vital to Athenian power, its imperial position created a unique set of interests and fears. With regard to Sparta, Athens was acutely sensitive to its relative position: Sparta was ‘‘by then not our friends as you once were but a source of suspicion and contention, and allies who left us would have gone over to you’’ (I.75). With regard to the allies, Athenian behavior was strongly motivated by the fear of the resentment its alliance system may have generated, a theme later emphasized at Melos in Book V. As Pericles would claim in Book II, the empire may have been unjust to take up, but it was now dangerous to put down. Their decision to retain the empire, as well as their coercive management of it, is also consistent with what they characterize as a political law of human nature. According to Athens, it has ‘‘done nothing remarkable, or contrary to ordinary human behavior, if we not only accepted an empire when it was offered but also did not let it go . . . not as the originators of such conduct, moreover, as the rule has always existed that the weaker is held down by the stronger’’ (1.76). In this view, political actors do not forego opportunities to aggrandize power or to gain through the exercise of force, and are only limited in the scope of their intentions by countervailing power. This view, although rooted in a specific understanding of human nature, is entirely consistent with modern realism, which suggests that because states exist in an environment where unilateral force could be used to arbitrate disputes, states are interested in maximizing power relative to other states. The Athenian thesis also contains an important claim about justice. Athens contends that morality is subordinate to considerations of necessity and power, and that justice is contingent on a balance of power between states. JusticeFwhich Athens appears to loosely define as the absence of arbitrary coercion in managing political relationsFis only possible among actors between whom there is an equal distribution of power; because considerations of relative political power are primary, states do not forego opportunities to expand in order to reciprocate moderation or restraint. This logic is repeated by a number of actors in the History, including the Corcyrans in Book I and the Mytelineans in Book III. Interestingly, the Athenian representatives at Sparta claim to have behaved more justly than the distribution of power would enable, and that ‘‘all are entitled to praise whenever they follow human nature and end up behaving more justly than their actual power dictates’’ (I.76). Although seemingly contradictory in their selective acceptance and denial of moral agency, this statement in fact affirms the logic of political relations outlined by the Athenian thesis. First, because states under anarchy are primarily interested in advantage and expedience, claims about justice are arbitrarily employed; it is thus expected that Athens contends to be compelled when acting unjustly, and contends to be exercising agency when acting justly. I do JONATHAN MONTEN 11 not understand this section of the sentence, due mostly to the verbal phrase ‘‘contend to have been compelled,’’ which I’m not sure I comprehend; in addition, when this is juxtaposed to ‘‘exercising agency,’’ it has no parallel structure. Second, the act of giving justice without the expectation of reciprocity actually reinforces power asymmetries. The act of gift-giving without the expectation of reciprocity is often used to reinforce existing disparities in power (Crane 1998:chapter 5). This is evidenced by Athenian behavior at Mytilene and Melos; as Athens is pressured by the war, allied revolt, and the overextension of its power, it is less willing to act moderately toward its allies by deferring to the adjudication of disputes in terms of some legal framework, as was evidently the case in Book I. The logic of the Athenian thesis, and specifically with regard to the sources of Athenian empire, is most prominently extended in two other speeches. At Melos, Athens delivers its most notorious claim about politics, that ‘‘justice is what is decided when equal forces are opposed, while possibilities are what superiors impose and the weak acquiesce to’’ (5.89). Athens also reinforces the positional nature of its thesis; because of an ‘‘innate compulsion to rule when empowered,’’ Athens contends that ‘‘we know that you and anyone else who attained power like ours would act accordingly’’ (5.105). This is the correlational logic of the third-image realism: variation in external conditionsFwhich Athens seems to be defining in terms of relative material power positionFoutweighs variation in internal conditionsF political culture or institutionsFin determining state behavior. A final place where Thucydides represents the Athenian empire as a response to the anarchic condition of international politics is in Euphemus’ speech to the Camarinaeans (6.82-87). Early in its invasion of Sicily, Athens attempts to persuade Camarina to align itself with the empire, but anticipates that Camarina may be wary of a city whose source of power is the subjugation of former allies. Euphemus portrays the empire as a defensive measure to avoid being ruled by outside powers, first Persia and then Sparta. The empire is maintained out of fear, because ruling is the only way to escape being ruled by others. Athens thus links its security position to the steady expansion of its empire. This zero-sum logic is consistent with modern realism’s focus on relative gains; the logic of the system is such that securityFor not being ruledFrequires expansion, and this pressure is incumbent on all states, regardless of domestic political–cultural characteristics. An important distinction between modern and Athenian realism might turn on their respective views toward human nature. The Athenian thesis is driven by a specific view of human nature, that individuals are innately compelled to dominate when not opposed by countervailing power. According to Athens at Melos, the Athenians were not ‘‘the ones who made this law or the first to apply it after it was laid down,’’ but ‘‘applied it as one in existence when we took it up and one that we will leave behind to endure for all time’’ (5.105).13 At certain places in the narrative Thucydides seems to endorse this view, or at least the logic of there being ‘‘laws’’ of human nature; in both the Archeology (1.89–1.118) and during the Corcyran stasis (3.69), he remarks that these events will recur as long as human nature is unchanging. Although he may disagree with the Athenian thesis over the actual content of that nature, for Thucydides human nature is a ‘‘causal’’ condition in the presence of which we can expect certain recurrent outcomes. In contrast, a goal of contemporary realism is, as discussed above, to more explicitly reformulate expla- 13 In Lattimore’s translation, that this law of human nature was ‘‘laid down’’ may imply that Athens regards it as a human construct, and thus a potentially reformable aspect of human nature. Others interpret the Athenian statement at 5.105 as a broader, and even hubristic, claim about cosmic order, that both people and the Gods are compelled by the law that the weaker are ruled by the stronger. For the purposes of comparison, my more narrow, ‘‘positional’’ interpretation of the Athenian thesis suggests that this law holds as long as certain conditions (or the realist assumptions specified above) hold: the existence of autonomous political units that vary in terms of power and capabilities. 12 Thucydides and Modern Realism nations of the competitive nature of international politics in terms of the effects of the system itself, and not the inherently dominating character of the individual agents that constitute that system. How can we square the importance of human nature to Athenian realism with the centrality of structure to modern realism? This distinction can have important consequences for realist theory. For example, Steven Forde (1995:151) argues that if the Athenian, nature-oriented paradigm is correct, then international politics is inexorably competitive, whereas an emphasis on the causal effects of structure at least introduces the possibility that interstate competition can be ameliorated or reduced. The answer is that both views are in effect ‘‘positional.’’ First, both anarchy and nature are constants, or at least portrayed as invariant. It can be conceded that the Athenian thesis is a unit-level claim, but because nature is treated as constant, to a significant extent the concept doing the explanatory work in the Athenian thesis is structural variation in relative power position. Given the laws of political human nature posited by Athens, cities with varying political cultures will act similarly when under similar conditions of relative power. Second, the Athenian thesis, like structural realism, is relational in logic: Athenian claims to an ‘‘innate compulsion to rule’’ when empowered are framed in terms of relative power. Whether because of nature as Athens portrays it or the system, both the Athenian and modern iterations of realism expect that states will act similarly when similarly situated, and differently when differently situated, independent of varying properties at the domestic level. Athenian and realist expectations regarding state behavior effectively hold under the same conditions: independent political units with varying capabilities seeking survival in the absence of an overarching political authority. Corinth, Pericles, and Political Culture In terms of explaining Athenian behavior, both Corinth at the Peloponnesian Congress and Pericles in his Book II speeches subscribe to a similar perspective on international politics: Athenian imperial behavior is attributable not to the anarchic nature of the international system, but to characteristics internal to Athens. Although diverse and varied in their judgments of Athens, these arguments all share a common second-image logic about the impact of political culture and institutions on international behavior. Thucydides shows through both the Peloponnesian Congress debate and the figure of Pericles that the international history of the war is as much about political relations within states as between them. In contrast with the Athenian’s positional explanation of empire, the Corinthian speech locates the sources of Athenian behavior directly in the character of the city. In this view, the empire is a consequence of institutions and a political culture unique to Athens. Athenian institutions encourage a political culture of innovation, boldness, and risk taking; according to the Corinthians, the Athenians are ‘‘innovators and quick to carry out their plans . . . they are bold beyond their strength and risk-takers beyond their judgment’’ (1.70). The Corinthian speech, while clearly motivated by instrumental and rhetorical objectives, also highlights the causal role of political culture and domestic character by juxtaposing Athenian and Spartan cultural attributes. Whereas Athenian institutions encourage a culture that is innovative, bold, and ‘‘quick to carry out whatever action it resolves,’’ Sparta is ‘‘[quick] to preserve the status quo, to make no further resolutions, and in [their] actions not even complete what needs to be done’’ (1.70). The Athenian and Spartan dispositions toward ‘‘intercity’’ politics are fundamentally divergent; partly because of such intracity factors as the Helots, Athens, according to Corinth, is ‘‘always ready to act while [the Spartans] are delayers, and they are always abroad while you are the most home-bound of all. For they believe that by being away they are gaining; you, that by making any move you will damage JONATHAN MONTEN 13 even your present assets’’ (1.70).14 Although the ensuing exchange between Archidamos, who broadly accepts the substance of the Corinth speech but reverses its implications, and Sthenelaides shows that Greek city-state political culture is not uniform but contested, the actual outcome of this contestation is not relevant to the logic of second-image arguments. Interestingly, Pericles’ funeral oration also subscribes to this second-image logic, attributing Athenian power to properties of its political and social order, and specifically its democratic political institutions and culture. Although Pericles’ vision of Athens is prescriptive as well as descriptiveFthere is an implicit normative dimension to his positive statements about the political character of AthensFhe portrays Athens as exhibiting a unique and distinctive political–cultural paradigm. According to Pericles, Athens’ is governed by a set of democratic institutions that, in addition to according each private citizen a formal equality under the law, fosters a unique concern for merit and distinction in public service. Athenian institutions promote a political culture that values daring, fame, and innovation, as a consequence of which Athens has achieved the greatest reputation and prestige. Athens has become an ‘‘education for Hellas,’’ where all the virtues uncompromisingly convergeFan Athenian is ‘‘self-sufficient in the most varied forms of conduct, and with the most attractive qualities.’’ The particular importance of reputation as a political–cultural virtue is reflected in speeches both before and after the plague, and again may be more prescriptive in what it selects to emphasize than descriptive: Athens has ‘‘acquired certainly the greatest power known up to this time, of which it will be forever remembered by posterity, even if in the present we give way somewhere . . . we as Hellenes ruled over the most Hellenes, sustained the greatest wars against them both in combination and separately, and lived in a city that was in all ways the best provided for and greatest’’ (2.63). Pericles also highlights the uniquely democratic and participatory nature of Athenian deliberative institutions as a source of political power, and a condition for Athens’ empire and material supremacy. By providing an egalitarian environment in which every citizen has an opportunity to participate in public life, Athenian democracy produced, according to Daniel Garst (2000), a ‘‘unity of will among its citizens that is far stronger than that resulting from blind obedience to the state.’’ Pericles juxtaposes the voluntary, consensual bravery and courage of Athenians to that of Spartans, the latter owing ‘‘more to law than to character’’ (2.39). Certain places in the History also present an interesting link between democratic institutions and naval power. In Book VIII, for example, Thucydides’ account of the defeat of the oligarchic coup against the democratic regime in Athens largely ascribes its failure to the resistance of the armed forces, and most notably the navy based in Samos (8.72). Garst also cites Aristotle, who believed that sustained naval power was incompatible with oligarchy. Evidently rowing a trireme is a very democratic activity. Pericles advances a certain ethos or vision in his characterization of Athens, specifying that what should be praised are innovation, daring, merit, and the reputation and prestige these acts accrue. These attributes have produced exhibitions of power that ‘‘will be admired by this and future generations,’’ and the ‘‘factual truth’’ of Athens power ‘‘we acquired because of these characteristics’’ (2.41).15 Corinth largely agrees with Pericles’ characterization of Athenian political culture, but represents this ethos as an almost pathological, and second image, source of 14 It is interesting to note that while Corinth portrays Athenian political culture as pathological and alien (i.e., closer to Persian than Hellenic culture), it still encourages Sparta to imitate it. This is broadly consistent with the structural realist mechanisms to be discussed in part three of this essay, in which states, because of the competitive pressures under anarchy, seek to emulate successful behavior. 15 Pericles’ focus on the ‘‘facts’’ of Athenian power at 2.41 clearly emulates Thucydides’ methodological realism at 1.21; Athenian exhibitions of power are like the war itself, which, as narrated in Thucydides’ text, will ‘‘require no Homer to sing our praises nor any other whose verse will charm for the moment and whose claims the factual truth will destroy’’ (2.41). 14 Thucydides and Modern Realism conflict. In his eulogy of Pericles at 2.65, Thucydides suggests that this political– cultural ethic of fame and merit may ultimately be destabilizing and self-defeating for the political community itself; the political competition that ensued following Pericles’ death over the de facto position of ‘‘first man’’ was in part responsible for Athens’ defeat in the war. More broadly, Thucydides offers both an endorsement and a critique of Pericles’ vision for Athens. On one level, the Periclean ethos and its focus on great motion and energy fulfills Thucydides’ criteria of the ‘‘greatest disturbance’’ as to why the Peloponnesian War was ‘‘notable beyond all previous wars’’ (1.1). As the war produces a certain secular disintegration in cultural and civilizational standards, however, Thucydides shows that the alternative to great motion is the great suffering shown throughout the narrative, and most conspicuously by the indiscriminate and irrational violence and destruction of Hellenic education at Mykalessos by barbarians at the discretion of Athens, a Greek city. Competing Images and Thucydides The Corinthian and Athenian speeches at the Spartan Congress frame competing causal propositions about the sources of Athenian power specifically, but also the sources of international behavior more generally. They also organize a number of arguments in the book, from Athenian speeches to Pericles to Thucydides speaking in his own name, according to where they locate the primary element impacting the behavior of state. The secondary literature appears to be split on Thucydides’ position in relation to this simple, second versus third image typology. Garst (2000:68), for example, argues that ‘‘Thucydides departs from neorealist thinking on the Primat der Aussenpolitik . . . Thucydides’ history shows that political institutions are equally, if not more, important in determining states’ behavior.’’ Alternatively, Forde (1995:151) argues that ‘‘one of the goals of the History is to test this realist Athenian thesis against the facts he has in view. The evidence he presents corroborates the thesis in its essential outlines.’’ Here I would like to make two points about this debate and the evidence regarding the sources and conduct of Athenian imperialism, the one ‘‘empirical’’ case discussed in this section. First, Corinthian Innenpolitik clearly prevails over Athenian Aussenpolitik. Thucydides does present us with clear examples of self-regarding, power-political behavior, in radical departure from the values of the ‘‘ancient simplicity’’ that previously defined, or were thought to have defined, Hellenic civilization.16 With regard to the Athenian empire, however, Athens’ third-image view can at best explain its response to a given distribution of power, while second-image arguments about political institutions and culture are necessary to explain why this particular distribution of power came about, and specifically why Athens developed and then consolidated its empire. The logic of the Corinthian view, supported by Athens’ very own ‘‘first man,’’ suggests that the ‘‘position’’ in which Athens found itself was in fact a consequence of characteristics unique to the organization of its polity. If a paradigm privileges some factors over others, third-image realism fails to capture significant elements of the dynamics motivating the Athenian empire. Second, this debate is only the first stage in understanding the relationship between Thucydides and modern realism. Waltz’s variation shares what I have been calling ‘‘third-image’’ realism’s emphasis on the insecurity and competition generated by the structure of international anarchy, but suggests a different way of specifying the effects of the system on state behavior. Whereas third-image realism cannot account for an important domestic-political element to Athenian imperialism, the nature of Waltz’s structural logic allows him to concede the significance of domestic level and ideational causal effects. Many secondary authors make the 16 In Crane’s intepretation, Thucydides used this phrase to capture the radical nature of the Athenian thesis, and the extent to which it subverted traditional Greek culture. See Crane (1998). JONATHAN MONTEN 15 mistake of assuming that demonstrating the importance of non-structural factors in The Peloponnesian War severs the connection between Thucydides and structural realism. The assumption that the proliferating variables highlighted by recent scholarship on ThucydidesFwhether morality, justice, legitimacy, piety, rhetoric, individual character, national character, ideology, regime type, etc.Fundermines a structural realist reading of The Peloponnesian War relies on a fundamentally misspecified version of realism.17 However, although a weaker casual theory in terms of modern social science standards, Waltz’s iteration of structural (or ‘‘neo-’’) realism better situates the facts as presented by Thucydides. Structural Realism, Properly Formulated Waltz’s reformulation of a structural theory of international politics begins with his sparse definition of political structure. Waltz argues that political structure consists of three elements: an ordering principle, a specification of the functions performed by the actors, and a distribution of capabilities or power across those actors. According to Waltz, the ordering principle of international politics is anarchic, the primary political unitsFstatesFare undifferentiated in terms of the functions they perform (i.e., they must independently provide for their own security), and states vary in terms of the capabilities they can bring to bear to perform these functions. Waltz further assumes that states are unitary, purposive actors who, at minimum, seek their own preservation. In Waltz’s view, international-political theory is analogous to microeconomic theory. The international systemFlike a marketFis created by the actions of its units, and the theory is built from the assumed motivations of these units and the systemic constraints that arise from their interaction. Microeconomic theory posits the existence of firms, assumes for them the motivation of maximizing profits, and explains their behavior based on environmental factors. Propositions about variation in behavior correspond with variation in characteristics of the system or of the unit’s position in that system, and not with variation in the units themselves. Similarly, and like third-image realism, Waltz believes that structural constraints explain why certain behavior recurs despite variation in the people and states that constitute the international system.18 Unlike the third-image realism discussed above, however, Waltz does not derive determinate predictions about how states will respond to these structural pressures. In his causal story, structure does not determine state behavior, but by introducing certain costs and incentives predisposes or constrains states in certain directions. According to Waltz (2002), structures ‘‘shape and shove; they do not determine the actions of states . . . international political theory deals with the pressures of structure on states and not with how states will respond to those pressures. The latter is a task for theories of how national governments respond to pressures on them.’’19 International structure impacts state behavior by providing incentives to act consistent with power-political imperatives, or suffer ‘‘costs’’ in terms of their territorial integrity and domestic political or cultural order accordingly. The logic of Waltz’s theory is that when agents are ordered by force and competition and not by 17 For a survey of alternative variables highlighted by recent scholarship, see Welch (2003). On the relationship between microeconomics and structural theory, see Waltz (1979:118) and Keohane (1986:158). 19 For Waltz this difference turns on a distinction drawn between ‘‘theories of international politics’’ and ‘‘theories of foreign policy,’’ the former being a theory that explains international outcomes (i.e., the recurrence of a balance of power or the difficulty in solving global collective action problems) and not a theory that explains particular foreign policy decisions. For the purposes of this paper, Waltz’s structural realism can explain ‘‘costs’’Fnot the specific decisions of states, but the international consequences of those decisions. For the debate on what constitutes a true ‘‘theory of foreign policy,’’ see Elman (1996), Waltz (1996), Fearon (1998), and Zakaria (1998). 18 16 Thucydides and Modern Realism authority and law, certain behavior is privileged or rewarded, but not necessarily expected. What are the constraints and incentives presented to states by the international structure?20 As a set of autonomous political units, what are the features of the Greek international political system, and in what directions do they ‘‘compel’’ states? By positing that at minimum all states seek survival, Waltz contends that a system of decentralized competition creates powerful incentives for all states to behave in the self-regarding, power-political manner captured by the Athenian thesis. In the context of the Greek self-help world, these include an acknowledgment of the primacy of material power, the pursuit of expedience and immediate advantage over the norms that defined, or were thought to define, the Greek moral and civilizational order, including reciprocity, piety, and ritualized friendship, a tendency to balance against power and compete for security, that is, regard security as a relative, zero-sum game, to cooperate only with equals or when interests converge, and to pursue unilateral advantage over unequals. Most broadly, these systemic ‘‘compulsions’’ are captured by the idea, articulated by Athenian speakers throughout the History, that states either rule or are ruled (e.g., at 6.18 and 6.82), and that considerations of justice are only possible between equals (e.g., at 5.89). In a subtle but crucial distinction, Waltz’s international-political theory requires no assumption of rationality. The mechanism that drives international politics in Waltz’s model is not ‘‘rational’’ responses to international anarchy but a process of selection and socialization that takes place in all competitive systems: states that do not emulate successful behavior or act on the basis of necessity and power-political expediency are ‘‘selected out’’ of the system. An international political system thus places significant pressure on states to act consistent with the structural imperatives of Athenian realpolitik, but it is not anomalous if they act ‘‘irrationally.’’ Waltz does not expect that all states will act like Athens (as does, as we have seen, third-image realism), only that states will suffer costs in terms of political–cultural autonomy if they do not. The logic of this situational or structural argument allows Waltz to concede domestic-level causal effects; it is thus not enough to demonstrate that Thucydides has a position on what motivates state behavior, or that states deviate from the structural incentives specified. Cities can act consistent with conceptions of morality and justice and can prosecute wars in a manner consistent with unit-level, political– cultural attributes, but the logic of an international system is such that they will be ‘‘selected out’’ for acting inconsistent with power-political imperatives of necessity and expedience.21 Whereas the significance of political culture in Thucydides’ narrative does contest the Athenian-style, third-image realism formulated above, Waltz’s realism is entirely consistent with a theory specifying the impact of political 20 In order to be a predictive theory of ‘‘costs,’’ and to avoid tautological causal reasoning, a structural theory must specify ex ante what behavior will be rewarded or punished. This is precisely what is at stake between offensive and defensive realism, the dominant contemporary debate within structural realism. These two schools share core realist assumptions about the primacy of self-interested states under anarchy, but whereas offensive realism contends that the international system pressures states to maximize their power relative to others, defensive realism contends that the system compels states only to seek security, to which expanding power might be one end. Some argue that Waltz endorses or implies the security-maximizing view; see, for example, Schweller (1996). However, Waltz (1979:118) himself has been ambiguous on this debate, claiming in Theory of International Politics that a structural theory requires only that states are ‘‘unitary actors who, at minimum, seek their own preservation and, at a maximum, drive for universal domination.’’ The Athenian thesisFwith its emphasis on the zero-sum nature of politics, on ruling or being ruled, and being compelled by necessity to expand the empireFis probably closer to the offensive realist construction of maximizing relative power. Athenian speakers consistently advance the idea that even states with defensive intent are compelled to behave aggressively, an argument that closely parallels John Mearsheimer’s. On the offensive and defensive realist debate, see Zakaria (1992), Mearsheimer (2001), Walt (2002), and Schweller (1994). 21 Again, this illustrates the mistake made by many of the authors cited above in assuming that demonstrating the importance of non-structural causes severs connection between Thucydides and structural realism. JONATHAN MONTEN 17 culture. Athens expects that, based on a specific understanding of human nature, cities with varying political cultures will act similarly when subject to the same external compulsions; Waltz, based on a specific understanding of how systems influence the behavior of their units, expects only that they will suffer ‘‘costs’’ terms of political and cultural autonomy if they deviate from the situational expectations of Athenian realpolitik. According to Waltz (2002), history ‘‘abounds in examples of states that failed to mind their own security interests through internal efforts or external arrangement, and as one would expect, suffered invasion, loss of autonomy, and dismemberment. States are free to disregard the imperatives of power, but they must expect to a pay a price for doing so.’’ There are analytical advantages and disadvantages to this spare conceptual model, especially as applied to Thucydides. On one level, Waltz’s structural realism makes very weak causal claims; it is ‘‘underdetermined’’ to the extent that its causal conditions are consistent with the wide variety of political outcomes (in this case, state behavior) witnessed by Thucydides in the politics of the Peloponnesian War. As a consequence, however, it is highly transposable; it applies to any political system in which autonomous units seek survival.22 The expectation that states suffer from deviating from realpolitik behavior should obtain whenever these specified conditions of political structure are present. A structural theory formulated in this way accounts for the enduring relevance of realism, and enables it to apply usefully to a number of political systems despite significant variation in the units that comprise that system, from Greek city-states to Italian principalities to the modern, postWestphalia international system. Structural Realism, Melos, and Athens Thucydides’ narrative provides evidence that states do suffer costs in terms of security, political cultural autonomy, and at times actual survival. The theme of cities emulating successful behavior or failing runs throughout the work, possibly the most explicit being the attempt by Corinth to persuade Sparta to emulate the Athenian culture of innovation and boldness at the Spartan Congress in Book I and Hermokrates’ imploring of Syracuse to emulate Athens in Books VI and VII. Similarly, cities are punished if they act contrary to the logic of their position under anarchy, whether conceived in terms of power-political laws of nature or the pressures created by structural imperatives. Two cases illustrate these arguments: Melos’ interaction with Athens, arguably the climax of political realism in The Peloponnesian War, and the Athenian failure to successfully prosecute the war. Melian Idealism The Melian dialogue contains the classic, oft-quoted statement of the Athenian thesis, that ‘‘justice is what is decided when equal forces are opposed, while possibilities are what superiors impose and the weak acquiesce to’’ (5.89), often cited by scholars as the earliest statements of the realist tradition. Athens uses the dialogue to reiterate a number of themes that characterize both their ‘‘procedural’’ and ‘‘paradigmatic’’ realism(s). Their interest in subjugating Melos is grounded in the strategic belief that the subject cities now pose a greater danger to Athens than does Sparta, and they reiterate that their ‘‘compulsion to rule’’ is a consequence not of cultural or institutional attributes unique to Athens, but to their relative material power position. Given a law of nature that Athens did not create or ‘‘lay down,’’ Athens ‘‘knows that [Melos] and anyone else who attained power like ours would act accordingly’’ (5.105). Procedurally, Athens frames the debate in terms of the factual reality of the situation and the logic of a self-help system; Melos should not ‘‘weigh 22 The costs and benefits of this analytical trade-off are discussed in Powell (1994). 18 Thucydides and Modern Realism . . . anything else besides planning your city’s survival on the basis of the present circumstances as you see them’’ (5.87). In fact, Melos responds in a way that challenges the Athenian thesis, and is anomalous from the perspective of a third-image realism that expects states under anarchy to act on the basis of rational self-interest and relative material power. Athens regards the Melian rejection of their offer ‘‘irrational, ‘‘ an act of ‘‘touching naivete’’ based on an illusion or imagination that ignores the reality of what is, or should be, immediately apparent. Melian decision-making is based on three factors that Thucydides presents throughout the narrative as fundamentally anti-realist. First, Melos’ decision is partly based on chance or hope; despite an imbalance of power, Melos argues that ‘‘warfare sometimes admits of more impartial fortunes than accords with the numerical superiority of two sides’’ (5.102). Second, Melos contends that there is a moral order, apparently enforced through divine intervention, that rewards and punishes just and unjust behavior. The Melians ‘‘have faith that we will not go without our share of fortune from the Gods, as righteous men who stand in opposition to unjust ones.’’ Finally, the Melian rejection is based on the expectation of support from an ally, Sparta: ‘‘the Lacedaemonians and their allies will redress our deficiency in power, compelled, if for no other reason, to help us on account of honor, on account of our kinship’’ (5.104). Alliances are typically considered to be one of the two traditional mechanisms of balancing, self-help behavior, and Melos seemingly relies on Sparta to redress an imbalance of power.23 However, Melos regards Sparta as ‘‘compelled’’ not by the realities of material power and situational necessities, but, as Lacadaemonian colonists, by the reciprocal obligations of honor and kinship. This view of alliances is contrary to the more typically realist view, presented, for example, by Corcyra and Myteline in Books I and III, that political cooperation is contingent on an underlying balance of power and convergence of interest (1.35, 3.11; see also 6.18, 7.57, 7.77). Ultimately, the Athenian offer is rejected on the grounds that Melos ‘‘will not in a matter of minutes do away with the freedom of a city whose habitation has lasted 700 years, but by trusting in the favor of the Gods, which has preserved it up till now’’ (5.112). Athens derides the decision as ‘‘fully irrational,’’ and ‘‘wishful thinking’’ that ‘‘when human means of saving themselves are still available . . . [men] turn to intangible ones, to prophecy, oracles, and whatever else of this sort combines with hope to bring ruin’’ (5.103). They also dismiss the Melian hope for Spartan assistance; extending the positional logic of realism, Athens argues that Sparta will not assist on the basis of kinship alone, in the absence of some immediate material interest. The Melian dialogue is widely regarded as the climax of the Athenian realpolitik that extends through the debate at Sparta in Book I, the speeches by Pericles, and the Mytilene debate, and provides the most dramatic illustration of many of its (and by extension, modern realism’s) key themes: the subordination of moral considerations to interest and expedience, the primacy of the existential survival of a political entity, the absence of coercion only in relations among equals, and the convergence of interests being the only stable source of cooperation. The actions of Melos itself, however, made on the basis of chance, honor, diffuse reciprocity, and speculation about the role of the Gods in human affairs, are not only contrary to the behavioral expectations derived by modern realism from the third image and by Athens from its putative laws of human nature, but also represent a discrete and competing political world view. Crane (1998) in fact argues that Athens crushed Melos not only because of the vital imperial interests threatened by continued Melian neutrality, but also because their continued existence represented a 23 The other being internal mobilization; see Waltz (1979) and Morganthau (1954). JONATHAN MONTEN 19 fundamental threat to the Athenian (and again, by extension, modern realism’s) political world view. The Melian dialogue, however, illustrates structural realist logic not because of Melian behavior as it relates to the Athenian thesisFit in fact contests its expectationsFbut because Melos pays a cost in terms of its survival for ignoring the logic of a system that rewards self-interested, power-oriented behavior, and discourages behavior driven by the factors listed above. The stakes of the dialogue for Melos were high; Thucydides dramatically concludes Book V with the elimination of Melos as an independent political entity; Athens ‘‘killed all the grown men they captured, enslaved the children and women, and settled the place themselves’’ (5.116). As a consequence of relying on chance, reciprocal obligations, and a quasipolitical power other than that mobilized by its own initiative, Melos engages in what from the perspective of third-image realism is clearly ‘‘irrational’’ behavior. As Forde (1995:145) argues, ‘‘violations of realist rationality are as salient in [Thucydides] as is realism itself. The Melians’ failure to surrender to the overwhelmingly superior power of Athens is only the clearest such case.’’ But rationality is not what interests structural realism; as we have seen above, a structural theory of international politics would not contest that 700 years of political–cultural continuity can impact a state’s decision-making process. Structural realism is only interested in the outcomes of those decisions, and its explanatory expectationFthat states that ignore the imperatives of a self-help system will be punishedFis vindicated by the events at Melos. The argument can be made that Melian behavior confirms politics as an exercise in power and self-interestFthat is, confirms the Athenian thesisFfor two reasons. First, Thucydides notes that the Melian oligarchs did not allow the Athenian representatives to speak before the public at large, a clearly self-interested act; Athens’ first statement in the dialogue is the observation that the debate is not open to the public ‘‘in order to avoid a continuous presentation by which the people would be taken in after hearing us say things that appealed to them’’ (5.85).24 Second, Melos frames its moral arguments to the Athenians around the instrumental value of justice, and not behaving justly for its own sake. By arguing that they ‘‘will not go without their share of fortune from the Gods’’ (5.104), Melos regards the Gods as effectively serving as a source of supra-state moral and religious order, equivalent to an overarching political authority or public agent that regulates political relations between cities by punishing or rewarding just and unjust behavior. Melos’ interest in moral behavior is not for its moral worth, but justice used instrumentally as a form of self-help (Ahrensdorf 1997:244).25 The first argument does not address any of the premises of structural realism; whether the decisions of domestic actors are instrumental or rational from the perspective of their private interests is not relevant to the international consequences or outcomes of those decisions. The second argument is particularly interesting, because it directly challenges the premise of anarchy; as Ahrensdorf (1997:244) asks, ‘‘insofar as realists contend that justice has no power in the real, anarchic world of international politics . . . how can the realists know that this assumption is true?’’ The Athenian response in 5.105 is that Melos’ belief in its own divine favor is contingent on a specific understanding of divinity; according to Athens, because it was not the first to ‘‘lay down’’ the law that humans are under an ‘‘innate compulsion to rule wherever empowered,’’ it is morally exonerated for acting in terms of necessity and interest. Moreover, it is evident throughout 24 This argumentFthat realism applies to the decision-making agents within states and not states themselves as unitary actorsFis advanced by Colin Elman and Miriam Fendius Elman (1995) in their response to Paul Schroeder’s critique of structural realism. 25 This corresponds to the distinction between actions based on a logic of consequences and actions based on a logic of appropriateness, see Risse (2002). 20 Thucydides and Modern Realism Thucydides’ narrative that while people’s subjective religious beliefs matter in terms of motivating or impacting political behavior, the Gods themselves do not play an active role in human affairs. Athens and Realpolitik This understanding of structural realism also provides better insight into the role of Athens in the Peloponnesian War than unreconstructed third-image realism. Thucydides presents Athens as perhaps the primary practitioner of realpolitik, a view certainly shared by many of the secondary authors discussed here, yet they were defeated. Why did AthensFregarded by Corinth as the model of a successful political culture, one it implores Sparta to emulateFnot succeed, as structural realism might expect? An initial answer might be that both places in the narrative in which Thucydides comments directly on the causes of Athenian defeat involve how Athens deviates from the realpolitik ideal. First, in his eulogy of Pericles at 2.65, Thucydides projects how the domestic political competition to succeed Pericles as ‘‘first man’’ undermined Athens’ capacity to act as a coherent strategic actor. According to Thucydides, For as long as [Pericles] presided over the city in peacetime he led it with moderation and preserved it in safety and it became greatest in his hands, and when war broke out it is clear that he foresaw the power it had at this time . . . He said that by keeping quiet, looking after the fleet, not extending the empire, and not endangering the city they would prevail; yet they managed all the affairs in the opposite way, and in accordance with personal ambition and personal gain they pursued other policies that seemed unrelated to the war, to the detriment of both themselves and the allies (2.65). The ensuing political competition prevented Athens from consistently adhering to the strategy of attrition forged by Pericles in Books I and II, and held together under the plague and other stresses only by the force of his prestige. Consistent with Thucydides’ explanation, Michael Doyle (1997:74) argues that factionalism undermined Athens ability to ‘‘calculate their security with close attention to the threats posed and to the resources available to meet those threats,’’ as did Pericles.26 A second place where domestic-political competition and leadership are cited as causes of the Athenian failure occurs at 6.15, during the debate between Nicias and Alcibiades over the Sicilian expedition. Thucydides portrays Alicibiades as the most capable of the post-Perciles Athenian leaders, and the most effective in pursuing the Athenian ‘‘national’’ interest; ‘‘as a public person [he] managed the war with the utmost skill’’ (6.15).27 In many ways he also personally embodied the Athenian ideal of boldness, action, and ability outlined by Pericles in the Funeral Oration, although in doing so raised concerns about his private life and the ‘‘magnitude of his license’’ (6.15).28 As Alcibiades argued in the Sicily debate, ‘‘when I with these aspirations am personally assailed for them, consider whether my public management can be matched by anyone’’ (6.16). 26 For an evaluation of Pericles’ military strategy, see Kagan (1995). The most prominent example prior to 6.15 is probably 5.43, where, according to Alcibiades, he ‘‘brought together the strongest powers in the Peloponnesos with little risk or cost to [Athens] and made the Lacedaemonians contest everything in a single day at Mantinea; and as a consequence, even though they prevailed in the battle, their confidence is still not restored to this very day’’ (6.16). 28 See the Funeral Oration, 2.35–2.46. Thucydides’ treatment of Alcibiades is complex, as many scholars have recognized (e.g., Lattimore 1998). Although he embodied this Periclean ideal and distinguished himself from other leaders competing for power by his superior ability, he has also been called the ‘‘anti-Pericles’’ for subordinating public, city interests to personal interests. See his speech on patriotism at Sparta, which concludes with him imploring Sparta to contest Athens in Sicily (6.89–6.92). On Alcibiades as the ‘‘anti-Pericles,’’ see Crane (1998). 27 JONATHAN MONTEN 21 Although both Nicias and Alcibiades were assigned to lead the expedition, Alcibiades was eventually recalled. Why did Athens deliberately act contrary to its own self-interest, and particularly in the management of an issue absolutely vital to their security and prosecution of the war? Thucydides’ answer appears to be that he was feared as a potential tyrant, an extension of the domestic political competition cited in 2.65. Of Alcibiades, Thucydides writes: It was this which destroyed the Athenian city. The masses, frightened by the magnitude of his license in conducting his personal life and of his aims in absolutely everything he did, developed hostility towards him as an aspiring tyrant . . . by entrusting the city to others they ruined it in short order. Athens could have conquered Sicily and presumably won the war had they retained their most capable general, Alcibiades, who despite his private behavior was apparently best able to pursue Athenian affairs of state. A second dimension was the religious panic that accompanied the mutilation of the Hermes on the eve of the Sicilian expedition (6.27). Alcibiades was arrested, condemned to death, and ultimately forced to flee, in connection with both the crimes against the Hermes and an accusation that he hosted celebrations of the ‘‘Mysteries’’ in his private home. In part this was driven by the fear of Alcibiades as a tyrant; it was believed that ‘‘both the Mysteries and the mutilation of the hermes were connected with the overthrow of the democracy, and that none of this had been done without [Alcibiades’] complicity, adducing as evidence the undemocratic licentiousness of his conduct in general’’ (6.28).29 The events surrounding the investigation and trial were used as a pretext for domestic-political competition: ‘‘taking up the charges were those who especially resented Alcibiades for standing in the way of their assured ascendancy over the people’’ (6.27). There was also an independent religious element to these events: the mutilations were construed as ‘‘an omen for the voyage’’ (6.27), producing mass religious panic through the city and the fear that the expedition was, as Nicias would later say, ‘‘resented by the Gods’’ (7.77). Although Athens contends to behave consistent with moral laws they did not ‘‘lay down,’’ there is some evidence to suggest that Athens felt some underlying guilt or moral culpability for the empire and the necessities required to sustain it, and thus interpreted the mutilation of the Hermes as a signal of divine punishment (e.g., see 2.17, 2.54, 2.62, 3.37). Athens did not consider removing Alcibiades until after the religious crimes, and his alleged association with the Mysteries reinforced public angst about his leadership. According to Ahrensdorf (1997:257), Athens’ response to the incident ‘‘reveals the power of both their pious fears and their pious hopes, fears and hopes that overwhelm their capacity to pursue their self-interest effectively.’’30 As a consequence of domestic politics and Alcibiades’ presumed impiety, Athens recalled him and entrusted the pivotal military expedition to the more pious but less capable Nicias. Upon arriving in Sicily, Nicias squandered Athens’ initial strategic advantage by not immediately attacking, before Syracuse could organize a military response and while it was still intimidated by the magnitude of Athenian military power (7.42).31 Nicias also ceded the initiative to the arriving Spartan general, Gylippos, a mistake he himself later acknowledges. Later in Book VII, and after losing several military engagements, Nicias and the Athenian army witness an 29 These fears were exacerbated by a previous episode of Athenian history, in which celebrations of the Mysteries were associated with oligarchic conspiracy, see 6.53–6.59. 30 As Nicias says after the defeat, ‘‘if we were resented by the Gods for our expedition we have already been chastised sufficiently’’ (7.77). 31 ‘‘Although Nicias was terrifying when he first arrived, when he did not immediately attack Syracuse but spent the winter at Katana he was despised, and Gylippos took the initiative away from him by arriving from the Peloponnesos’’ (7.42). On Nicias’ strategic failures, also see Kagan (1981). 22 Thucydides and Modern Realism eclipse of the moon, which he construed as another bad omen. Hoping to appease the Gods and in deference to Athenian soothsayers, Nicias delayed the withdrawal from Sicily ‘‘thrice 9 days,’’ allowing Syracuse to encircle and decisively destroy the entire Athenian army (7.50).32 Under Nicias, the Athenian army is reduced to relying on hope and the favor of the Gods, precisely those means of statecraft for which they chastised the Melian oligarchs.33 In combination, these two qualities of leadershipFindecisiveness and what Thucydides calls Nicias’ ‘‘over-credulous’’ pietyFare more associated with the cultures of political communities like Sparta and Melos than Athens. The Sicily campaign represented a total strategic collapse for the city of Athens. Vital Athenian interests were at stake in the military outcome in Sicily, both because of the degree of military power committed by Athens, and because, consistent with what they believed to be the necessities and compulsions of the international system, they linked their security to the unabated expansion of the empire (2.64, 3.40, 5.85–113, 6.18. 6.82–87).34 Acknowledging the high costs paid by Athens for deviating from third-image pressures, the defeat was, according to Thucydides, ‘‘the greatest reversal for any Hellenic army’’ (7.75). Domestic politics and an attempt to ‘‘appease the Gods’’ interfered with Athens’ ability, or willingness, to pursue its own narrow material interests at stake in Sicily, and this explains why they were unable to sustain a foreign policy line consistent with the realpolitik paradigm outlined throughout the History. However, this is entirely compatible with structural realism as formulated by Waltz: the argument is not that domestic and ideational causal factors do not impact decisions and behavior, only that they do not negate the structural incentives states face, and that states often pay a price for acting contrary to them. Other scholars have used the Athenian case to examine the ethical and practical implications of political realism.35 Ahrensdorf (1997), for example, uses the dismissal of Alcibiades to demonstrate that political communities cannot meet the ‘‘psychological requirements’’ of political realism in practice and often backlash, in the Athenian case by becoming overly pious. Forde (1995) advances a similar critique of realism, that the case of Athens (and, although not mentioned, presumably Corcyra) demonstrates that the self-aggrandizing and self-interested behavior encouraged by realism abroad is not sustainable within a political community at home.36 Alcibiades also presents a variation of this argument, observing that those who ‘‘stand out’’ for their accomplishments in public affairsFthat is, effectively engage in realpolitikFinevitably engender resentment among their peers, 32 Thucydides eulogizes Nicias as conducting ‘‘a life entirely directed towards virtue’’ (7.86), a comment which many authors have interpreted as a critique of Nicias’ leadership, see Lattimore (1998:406). 33 According to Leo Strauss (1978:209), ‘‘Alcibiades’ . . . presumed impiety made it necessary for the Athenian demos to entrust the expedition to a man of Melian beliefs whom they could perfectly trust because he surpassed every one of them in piety.’’ 34 As Nikias stated to Athenian hoplites before what would be the decisive battle, ‘‘if the outcome for you is anything other than victory tour enemies here are going to sail immediately against what remains back there . . . So while you would immediately fall into the hands of the Syracusans . . . those [in Athens] would fall into the hands of the Lacedaemonians.’’ ‘‘This single contest’’ is for ‘‘a double cause’’ (7.63). Thucydides directly connects an Athenian victory in Sicily with the security of its empire, observing that ‘‘if [Syracuse] could defeat the Athenians and their allies both on land and at sea, their feat would appear glorious in the eyes of the Hellenes; immediately, the other Hellenes would be either set free or delivered from fear (for the remaining power of the Athenians would be incapable of bearing up under the war that would subsequently be brought against them)’’ (7.56). 35 As mentioned earlier, these are examples of realist, ‘‘second-image reversed’’ arguments, in which the pressures of international political competition shape the quality of domestic politics. See Gourevitch (1978) and Zakaria (1992). 36 In contrast with Forde, Ahrensdorf argues that Athens lost the war because it was too pious, not because they were too impious. From the perspective of structural realism, both arguments rely on the same second-image logic, and involve factors that cause Athens to deviate from the narrow pursuit of its strategic interests. JONATHAN MONTEN 23 although the renown they gain through their reputation for success publicly benefits everyone in a community.37 But the logic of these arguments is subsumed by, and even confirms, structural realism as formulated by Waltz. Whether Athens lost the war because it became a moderate Corcyra (consumed by self-interested domestic politics) or a moderate Melos (relying on moral and religious hopes), it suffered immense costs for deviating from rational, self-interested behavior. While arguably discrediting of a more deterministic third-image realism, Athens’ experience in the war in fact indicates Waltz’s structural realism. Conclusion Waltz’s structural realism reconceives how systems exert effects on the political units of which they are comprised. A properly specified structural reading of Thucydides yields a different picture of the Peloponnesian War, highlighting not that states conform to the Athenian thesis, as many scholars assume, but that states suffer costs to the extent they deviate from the situational expectations of Athenian realpolitik. This article illustrated this argument with two examples, but could be expanded to include others, including cases of political actors successfully conforming to the competitive pressures of anarchy despite traditionalist cultures, such as Sparta and Syracuse in Books VI and VII. What is the value added of what some might regard as a minor theoretical exercise, and others an attempt to use a canonical text to validate or legitimize a particular modern theoretical perspective? Although much of The Peloponnesian War substantiates this narrow version of structural realism, there are also ways in which a more complex reading of Thucydides both critiques and builds on Waltz’s realism. A highly nuanced work like The Peloponnesian War is well suited to examining the interaction of factors located at different levels of analyses and across the materialist/ideational divide, such as human nature, political culture, identity, and rhetoric. Recognizing the importance of these other influences, however, does not negate or alter the structural constraints and incentives elucidated by Waltzian realism. This suggests ways of combining different theoretical traditions; for example, acknowledging both the autonomous influence of anarchic structures and norms and identity captures an important intersection between the constructivist and realist research programs (Barkin 2003; Jackson 2004). Scholars need not battle over whose theoretical camp Thucydides belongs in; in the substantive events he presents and the political ideas he advances, Thucydides demonstrates that a structural approach need not exclude attention to variation in unit-level attributes. As Stacie Goddard and Daniel Nexon (2005) argue, cultural or alternative domestic phenomena ‘‘might be integrated into structural realism without sacrificing Waltz’s insights into the implications of anarchical orders for those situated within them.’’ Waltz himself anticipates this idea, and argues to the contrary that theories are not just collections of assorted variables, but conceptual frameworks that relate phenomena in coherent and logical ways.38 This argument is similar to what other scholars, working in the philosophy of science tradition of Imre Lakatos, refer to as a regressive ‘‘problemshifts,’’ in which variables are added on an ad hoc basis to 37 According to Alcibiades, ‘‘let all submit to the arrogance of the successful . . . I observe that such men, indeed all men who stand out with any brilliance, are resented during their lifetimes, especially by their peers’’ (6.16). This parallels Pericles’ claim about the Athens’ success being resented in the wider Greek world at 2.64: ‘‘To be hated and disliked in season has been the situation for all alike . . . For hatred does not last long, but the brilliance of the moment and glory in the future remain in eternal memory.’’ 38 For Waltz’s view on the construction of theories, see Waltz (1979:chapter 1), and Waltz (1988:615–617). 24 Thucydides and Modern Realism account for empirical anomalies generated by the original terms of a theory (Elman and Elman 2003; Elman and Vasquez 2003). Of the many things that concerned Thucydides about political life, however, we might say with some confidence that regressive problemshifts were probably not among them. In the context of a well-crafted story, propositions often portrayed as mutually exclusive become eminently compatible. Thucydides shows us the value of a richer approach that artfully incorporates a diverse range of influences into a compelling account, possibly a more important methodological lesson for realism and the wider discipline than his contested claim to have focused on ‘‘the facts themselves.’’ References AHRENSDORF, PETER.
