This essay addresses the often neglected role of comparison in political thinking (both formal and everyday). It calls attention to the spatial reasoning of comparisons. In doing so, this article first discusses topological reasoning in debates over the scope and boundaries of the discipline of political theory, and reviews a variety of spatial imaginings found in substantive theoretical arguments, most notably in the field of comparative political thought. This article then looks closely at three recent examples of thinking elsewhere by Anglo-American theorists: John Rawls's The Law of Peoples, Andrew March's Islam and Liberal Citizenship, and John Bowen's Islam, Law, and Equality in Indonesia. In these three texts, Islam is taken to be the proximate elsewhere of political liberalism. This article demonstrates the importance of comparison and topological reasoning in contemporary political theory in general, and in liberal political thought in particular.

He criticizes political theory for its propensity to avoid "geographical and moral elsewheres" in favor of liberal ideological concerns and the "North Atlantic canon." 1 This essay examines the status of such "elsewheres" in political theory and attends to the way political thinkers, when delving arguments, turn to other societies, antiquities, states, utopias, or distant locales.
