The 2015 Antipode RGS‐IBG Lecture was delivered by Prof. Paul Gilroy on 2 September at the Royal Geographical Society (with the Institute of British Geographers) Annual International Conference. Prof. Gilroy's lecture interrogates the contemporary attractions of post‐humanism and asks questions about what a “reparative humanism” might alternatively entail. He uses a brief engagement with the conference theme—“geographies of the Anthropocene”—to frame his remarks and try to explain why antiracist politics and ethics not only require consideration of nature and time but also promote a timely obligation to roam into humanism's forbidden zones.
