Kant’s Metaphysics of Morals, while useful for moving past the ecological limitations of the standard reading, is limited insofar as it focuses on individual actors—consumers, citizens, and politicians in particular. Kant’s ethical thought emphasizes individual humans rather than economic and political systems, and his teleological thought appears scientifically outdated. This chapter asks whether these aspects of Kant’s thought need revision. It begins by placing Kant in dialogue with Darwin and Marx, pursuing a critical discussion on the human species and political systems in the context of the Anthropocene. The Kantian reply, I suggest, encourages us to reconsider Kant’s philosophy of history and philosophical anthropology. Kant’s ideas are significant for the climate crisis insofar as they enjoin normative reflection on the human species globally and in the long term. I conclude with critical reflections on Kant’s racism and sexism as obstacles to reading Kant in the Anthropocene.
