Draws on Marx and the first-generation Frankfurt School to make the case that cosmopolitanism must become a postcapitalist political theory.

The Dialectics of Global Justice uses a novel application of negative dialectical interpretation to offer an immanent and ethical critique of prominent theories of global justice (i.e., cosmopolitanism), including how these theories manifest in political movements and policy agendas. Drawing on the work of Theodor Adorno and Erich Fromm especially, author Bryant William Sculos exposes the contradictory relationship between cosmopolitanism and core elements of capitalism, particularly the domineering "capitalistic mentality" (re)produced by and through capitalism, leading to the conclusion that cosmopolitanism, on its own terms, demands an alternative, postcapitalistic political basis in order to make robust progress toward global justice. While offering this critique, Sculos also implicitly challenges the increasingly common view that cosmopolitanism today is inherently imperialistic and out of touch with the global resurgence of nationalism and anti-cosmopolitan sentiment.
