Pluralismâwhich maintains that there are many legitimate âways of knowingâ and thus endorses a wide range of epistemological, theoretical, methodological, and empirical/spatial perspectivesâhas recently become one of the major topics discussed and debated in the field of International Relations (IR).1 As there are manifold issues and implications associated with pluralism, the ongoing discussion, too, appraises pluralism from diverse angles in different forms with varying emphases. For example, whether IR ought to be a pluralistic discipline is one of the several questions that concern many scholars (for recent works, see, e.g., Lebow 2011; van der Ree 2013; Rengger 2015; Ferguson 2015). The extent to which IR needs to become pluralistic (see, e.g., Jackson 2011, 2015; Sil and Katzenstein 2010, 2011; Lake 2011; Reus-Smit 2013) is another question; and âwhat kindsâ of pluralism the discipline should pursue is also another important dimension of the pluralism question (see, e.g., Tickner 2011; Dunne et al. 2013; Wight 2013; Acharya 2014, 2016). Given such a remarkable interest in pluralism, one might describe the ongoing discussion as a pluralist turn in IR, although (as will be discussed in detail in the next chapter) it is unclear whether the field has archived what an academic âturnâ is expected to achieve. Let me further clarify the terrain of the developing discussion about pluralism.
Persistent Pleas for a Pluralistic IR
Obviously there is a place for both the pros and cons of pluralism in the study of world politics, and there is also disagreement about the extent to which pluralism is useful in solving theoretical and empirical puzzles connected to world political processes and phenomena (see, e.g., Smith 2003: 141â142; Mearsheimer and Walt 2013: 427â457; van der Ree 2014: 219â230; Rengger 2015: 1â8). It is, however, clear that in recent years there has been a growing number of pleas for pluralism in IR. Going a step further, Thierry Balzacq and StĂ©phane J. Baele (2010: 2â4) have described the âthird debateâ in IR, which began âin the mid-1980s,â as a discussion that follows âa composite claim for a more diverse ⊠and more critical IR.â Relatedly, they observe that âdiversityâ has consistently remained the âstrongest statementâ of post-positivists. Further, pluralism and diversity are endorsed not only by post-positivists, who consider the vision of IR as a critical enterprise (George 1989; Ashley and Walker 1990; Campbell 2013), but also by scholars, who often invoke a strict rationalist ontology and follow a deductive-nomological modeling based on positivist epistemology. For example, John Mearsheimer and Stephen Walt readily âacknowledgeâ the utility of pluralism in the study of world politics, saying that IR will be âmuch better off a diverse array of competing ideas rather than single theoretical orthodoxyâ (Walt 1998: 30), and that âa diverse theoretical ecosystem is preferable to an intellectual monoculture ⊠We therefore favor a diverse intellectual community where different theories and research traditions co-existâ (Mearsheimer and Walt 2013: 430).2
Such a plea for endorsement of pluralism comes from different perspectives across varying realms of inquiry. For example, in his 2011 book, The Conduct of Inquiryâwhich provides an introduction to the philosophy of science issues and their implications for IRâPatrick Jackson argues for âa pluralist science of IR.â According to Jackson, IR should realize that there is a variety of claims about our âhook-upâ to the world, and thus âa variety of philosophical ontologiesâ (Jackson 2011: 32, 193). Since IR ought to embrace a wide range of ontology, how we should go about producing factual knowledge about world politics, namely methodology, should accordingly accept greater pluralism. Although his observation and suggestions are not without controversyâin effect, they have generated many acclaimed comments and critical reviewsâboth critics and advocates agree on the utility of pluralism in the study of international relations. Hidemi Suganami, for instance, takes issue with Jacksonâs treatment of philosophical foundations as âa matter of faith,â yet attempts to reinforce and complement âa pluralist science of IRâ by pointing to a need to add âthe political underpinnings of the various scientific methodologiesâ to Jacksonâs pluralist consideration of IR inquiry (Suganami 2013: 248, 267â269). Likewise, although Colin Wight is overall critical regarding Jacksonâs accounts of science and methodology, he nevertheless foregrounds âa deep commitment to pluralismâ in IR, suggesting that pluralism should âgenerate debate across and between approachesâ (Wight 2013: 329, 342â343).
Besides the acceptance of pluralism from the aforementioned metatheoretical and philosophical perspectives, pluralism is also highlighted and appreciatedâwith a different rationale and angle, of courseâwith regard to theory application and empirical analysis in IR. âAnalytical eclecticismâ might be a good case in point. Although, strictly speaking, the âanalytical eclecticismâ discussed and practiced in the field is not a genuine form of pluralism, especially in terms of its relationship with epistemology,3 it advocates a more nuanced and pluralistic analytical position while denouncing monocausal explanations. More specifically, Rudra Sil and Peter J. Katzenstein, who have long argued for âanalytical eclecticismâ note that it is possible and necessary to explore empirical issues and problems of world politics through eclectic recombinant modes of inquiry (see Sil 2000; Sil and Katzenstein 2010, 2011). âAnalytical eclecticism,â they explain, requires âexpansive, open-ended formulations of problemsâ that do not privilege a priori mechanisms or processes normally favored by any one paradigm; in this regard, the complementarity or intersection across contending paradigms is emphasized (Sil and Katzenstein 2011: 3â4). Put simply, it is against univariate explanationsâexplanations on which there is a single clear and dominating theory of and reason for the problem in questionâand instead prefers a âcombinatorial logicâ that draws insights from multiple theoretical perspectives. In this sense, âanalytical eclecticismâ can be characterized as a pluralistic approach of some kind; and this analytically pluralistic and eclectic position âhas quite rapidly become part of mainstream debates about the kind of knowledge the field [of IR] ought to pursue and how such knowledge is best attainedâ (Reus-Smit 2013: 591, 599). For example, such established IR scholars as David Lake welcome âthe rise of eclecticism.â In his keynote address delivered at the 2010 International Studies Association (ISA) Annual Conference, as well as in his more recent articles, Lake suggests that we focus on the development of âmid-levelâ theories tailored to the specific problems of world politics with âanalytic eclecticismâ (Lake 2011: 1â14, Lake 2013: 567).
In addition to the philosophical and analytical perspectives discussed above, a demand for pluralism has also been made in a more concrete study and subfield of IR, such as Foreign Policy Analysis (FPA). In their study of the patterns and processes of American foreign policy Eugene Wittkopf, Christopher Jones, and Charles Kegley foreground the importance of a multivariate model, noting that âwe are well advised to think in multicausal terms if our goal is to move beyond rhetoric toward an understanding of the complex reality underlying the nationâs foreign policyâ (Wittkopf et al. 2008: 19, original emphasis); and a large number of FPA scholars echo this point. Valarie Hudson (2007: 184), one of the leading FPA scholars, writes that âas the field of FPA was first being formed, the goal of theoretical integration was put forward as an essential task.â Similarly, Yong-Soo Eun (2012) notes that although FPA research is actor-specific and agent-centered in its orientation, variables from all levels of analysis, from the most micro to the most macro, may be of interest to FPA analysts to the extent that they affect the leaderâs definition (perception) of the situation at hand. In this respect, IR researchers concerned with why-questions about the stateâs external behavior have attempted to develop multifactorial explanations of foreign policy, with the desideratum of examining diverse variables from more than one level of analysis (see, e.g., Jensen 1982; Hill 2003; Mintz 2004; Neack 2008; Oppermann 2014).
Furthermore, in discussions of visions of a better future for IR scholarship, pluralism is also regarded as what we must pursue and achieve. Friedrich Kratochwil (2003: 126), for example, holds that pluralism is ânot as the second best alternative but actually the most promising strategy for furthering research and the production of knowledgeâ in the Forum that the ISA put together in the hope of identifying ânew directions for the fieldâ at the dawn of the twenty-first century. Going a step further, in the same Forum, Yosef Lapid calls attention to an âengagedâ form of pluralism, pointing to the importance of âdialogue,â as well as to the diversity of approaches, in the study of international relations. In his words: if âengaged pluralism ⊠is the most feasible and deserving destination for the international relations theory enterprise in the foreseeable future, then dialogue must figure prominently on our agenda at the dawn of the twenty-first centuryâ (Lapid 2003: 129). In effect, the underlying assumption of the Forum, as the Editor has made clear, was that IR is badly in need of âdialogue, pluralism, and synthesisâ if it is to have a better future (Hellmann 2003: 123, 147â150). And this view continues to resonate in todayâs IR. Yale Ferguson, for example, writes that IR analysts âneed to be conversant with a wide range of theories ⊠[because] viewing some subjects simultaneously from more than one theoretical perspective often enhances understanding of global politicsâ (Ferguson 2015: 3). Additionally, Richard Ned Lebow claims that â[p]luralism must be valued as an end in its own right but also as an effective means of encouraging dialogue across approaches, something from which we all have something to learnâ (Lebow 2011: 1225â1226).
The discussion of pluralism in IR involves not only conceptual (i.e., theoretical or epistemological) issues, but geopolitical concerns as well...
