Book excerpt: In Queer Social Philosophy, Randall Halle analyzes key texts in the tradition of German critical theory from the perspective of contemporary queer theory, exposing gender and sexuality restrictions that undermine those texts' claims of universal truth. Addressing such figures as Kant, Hegel, Marx, Nietzsche, Adorno, and Habermas, Halle offers a unique contribution to contemporary debates about sexuality, civil society, and politics.
