In early 2026, the editors of Political Theology invited Zahi Zalloua and Benjamin Davis to review each other’s books, To Exist As a Problem: Being Black, Being Palestinian and Another Humanity: Decolonial Ethics from Du Bois to Arendt. They also responded to each other’s reviews. What has resulted is a lively, friendly exchange, but also one that works through one of the starkest lines of disagreement in global critical theory today: whether “the human” is a useful concept to motivate solidarity, and, relatedly, whether theory should intervene at the level of ontology or praxis.
