Habeas Viscus focuses attention on the centrality of race to notions of the human. Alexander G. Weheliye develops a theory of "racializing assemblages," taking race as a set of sociopolitical processes that discipline humanity into full humans, not-quite-humans, and nonhumans. This disciplining, while not biological per se, frequently depends on anchoring political hierarchies in human flesh. The work of the black feminist scholars Hortense Spillers and Sylvia Wynter is vital to Weheliye's argument. Particularly significant are their contributions to the intellectual project of black studies vis-à-vis racialization and the category of the human in western modernity. Wynter and Spillers configure black studies as an endeavor to disrupt the governing conception of humanity as synonymous with white, western man. Weheliye posits black feminist theories of modern humanity as useful correctives to the "bare life and biopolitics discourse" exemplified by the works of Giorgio Agamben and Michel Foucault, which, Weheliye contends, vastly underestimate the conceptual and political significance of race in constructions of the human. Habeas Viscus reveals the pressing need to make the insights of black studies and black feminism foundational to the study of modern humanity.

The Jamaican writer and cultural theorist Sylvia Wynter is best known for her diverse writings that pull together insights from theories in history, literature, science, and black studies, to explore race, the legacy of colonialism, and representations of humanness. Sylvia Wynter: On Being Human as Praxis is a critical genealogy of Wynter’s work, highlighting her insights on how race, location, and time together inform what it means to be human. The contributors explore Wynter’s stunning reconceptualization of the human in relation to concepts of blackness, modernity, urban space, the Caribbean, science studies, migratory politics, and the interconnectedness of creative and theoretical resistances. The collection includes an extensive conversation between Sylvia Wynter and Katherine McKittrick that delineates Wynter’s engagement with writers such as Frantz Fanon, W. E. B. DuBois, and Aimé Césaire, among others; the interview also reveals the ever-extending range and power of Wynter’s intellectual project,  and elucidates her attempts to rehistoricize humanness as praxis.
