This essay builds on such scholarship, and on a broad-brushed survey of maritime history, to make two basic arguments. First, a look at political and legal processes regarding maritime spaces reveals that law is transnational ‘all the way down’. Legal theorists often assume that transnational legal processes are an added layer beyond domestic and international law. But the maritime perspective reveals that transnationalism comes first, both analytically and historically, as a constant negotiation of the relationship between what is ‘inside’ and what is ‘outside’ a polity. Second, the maritime space begins, at least in dominant legal traditions, as an absolute exteriority – imagined as outside or beyond polities and jurisdictions. But with the climate crisis and the emergence of the Anthropocene we may observe an inversion, the sea now appears as a record of harmful human activity; a mirror showing a troublesome collective portrait of humanity. The inversion from a maritime exteriority to the intimacy of ubiquitous environmental harm defines the parameters of law and politics today. The essay concludes with reflections on how the maritime perspective may best be engaged today in responding to that image through political action. It conceptualizes what I call the ‘commonist lifeboat’ – a model of bottom-up universalism for tumultuous times.","PeriodicalId":46771,"journal":{"name":"International Theory","volume":"33 3","pages":""},"PeriodicalIF":3.3,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139005248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If Eurocentric IR is guilty of ‘getting Asia wrong’, do students of historical Asia ‘get Asia right’? Analysts should avoid exotifying differences between the West and the East and ‘exchanging Eurocentrism for Sinocentrism’. This article tries to ‘get Asia [more] right’ by ‘disaggregating’ and then ‘reassembling’ taken-for-granted concepts by time, space, and relationality. When ‘Confucianism’ is understood to justify both war and peace in competition with other thoughts, it does not dictate peace among East Asian states or conflicts across the Confucian–nomadic divide. When ‘China’ is unpacked, it does not sit on top of an Asian hierarchy. When Korea's, Vietnam's, and Japan's views of their relations with China are examined rather than presumed, cultural legitimacy is thinned out. When ‘Asia’ is broadened to cover webs of relations beyond East Asia to Central Asia, Confucianism recedes in centrality and pan-Asian phenomena including Buddhism and the steppe tradition come to the fore. The article concludes that a better challenge to Eurocentrism is not to search for cultural differences but to locate Eurasian similarities that erase European superiority.","PeriodicalId":46771,"journal":{"name":"International Theory","volume":"117 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135565591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through its geo-epistemology, Global IR enables a conservative appropriation of the critique of Eurocentrism in IR. Globality becomes a matter of assembling sufficient geographic representation rather than an analysis of the discipline's political, historical, and spatial assumptions. Anglo-American policymakers and intellectuals invented the national/international world to replace the world of empires and races that came apart in the era of the world wars. This UN world of sovereign nation-states and their regional groupings was the foundational move of both what Stanley Hoffman called ‘the American social science’ – IR – and the American-centred world order.

Alongside these demands for theoretical pluralism can be found a concern for widening IR's historical frames of reference. Yet, to date, the relationship between global IR and history is the least developed part of the project's agenda. This article suggests two ways in which this relationship can be strengthened. One draws from global history, shows how transboundary connections and relational dynamics forge the units used by advocates of global IR in their analysis: West and non-West, core and periphery, metropole and colony. The other draws from global historical sociology as it advances the role of power asymmetries for understanding the patterns and entanglements in transboundary connections. Connecting global IR to global history and global historical sociology can help produce a fuller understanding of the interactive connections and asymmetrical entanglements between peoples, places, ideas, and institutions that drive historical development. We illustrate this potential through a brief analysis of the rise of the West. This, in turn, demonstrates the ways in which three visions of the global – global IR, global history, and global historical sociology – can be mutually beneficial.","PeriodicalId":46771,"journal":{"name":"International Theory","volume":"114 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135565596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our symposium supports Global IR's goals but also offers some friendly critiques of the project with the aim of increasing its impact and durability. In this Introduction to the symposium, we posit that Global IR is vulnerable to a dynamic that limits its capacity to upend the status quo, which we term the ‘essentialism trap’. Essentialism captures a range of commitments oriented around the notion that the world is constituted by pre-formed, fixed, internally coherent, and bounded social forms. The trap involves the overuse of essentialist categories by radical projects, a process that can result in the reinforcement of status quo categories and assumptions. With reference to previous openings in IR that have succumbed to this trap, we identify the dynamics that lead to this trap and suggest ways in which Global IR can avoid it by leaning more into relationalism and global history, and, thereby, fulfil the promise contained in the range of movements it speaks with and for.","PeriodicalId":46771,"journal":{"name":"International Theory","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135565593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper turns this argument on its head, arguing that IR was ‘global at birth’. Concentrating in particular on the implications that global IR debate has for our understanding of the historical development of disciplinary knowledge, the article argues that both conventional and critical stances within this debate tend to express a substantialist conception of knowledge formations, one which encourages diffusionist ideas of the spread of knowledge from an origin to a destination, and essentialist representations of specific geographies of knowledge. In order to address this, the paper proposes a relational sociology of disciplinary knowledge that offers a more historically grounded understanding of the ongoing, provisional, connected, and configurational nature of knowledge construction, without losing sight of the hierarchies that inflect this. The article applies this framework to archival work on the intellectual history of international thought in India, offering an approach that allows a global account of the development of disciplinary IR that operates within and beyond imperial frames, encompassing the entangled histories of colonial, anti-colonial, and postcolonial lineages of what became known as ‘International Relations’ in the 20 th century.","PeriodicalId":46771,"journal":{"name":"International Theory","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135566091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I remedy this by showing how property constitutes the core concepts of anarchy and sovereignty in international relations (IR) as overlapping spaces of right-based governance. I develop my account of a property-based world order in relation to the work of John Locke. Locke is generally overlooked as a core IR thinker, with the unfortunate consequence that anarchy and sovereignty are conceptualized as polar opposites under the enduring shadow of Hobbes. Even prominent critics of Hobbesian anarchy rely on Hobbesian notions of sovereignty, resulting in minimalist conceptions of international society and international ethics. To counter these Hobbesian legacies, I turn to Locke's limited, plural, and fluid accounts of anarchy and sovereignty and show how they are grounded in a normative notion of property that mutually constitutes them. This provides an alternative to the Hobbesian absolutist conceptions of anarchy and sovereignty that many IR theorists still operate with. The result is a distinctly normative vision for IR that condemns the twin evils of conquest and tyranny.","PeriodicalId":46771,"journal":{"name":"International Theory","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135878400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, scholars have struggled to agree on the essential dispositional characteristics of this category of actors, stunting theoretical progress.

Combining this with and contributing to scholarship on hierarchy in international relations, I recast ‘middle powers’ as a category of practice and argue that one of the term's main uses is to differentiate certain status-anxious states – that hold no real prospect of achieving great power status – from ‘small states’ that occupy the lowest stratum of stratification within the ‘grading of powers’. Following an illustrative case study of Australian and Canadian attempts to establish the ‘middle power’ category in the 1940s, the article then outlines the contributions of the argument for the study of status and hierarchy in world politics.","PeriodicalId":46771,"journal":{"name":"International Theory","volume":" ","pages":""},"PeriodicalIF":3.3,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46533761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
