InRescuing Autonomy from Kant, James Furner argues that Marxism’s relation to Kant’s ethics is not one of irrelevance, complementarity or incompatibility, but critique. Although Kant’s formulas of the categorical imperative presuppose a belief in God that Kant cannot motivate, the value of autonomy can instead be grounded by appeal to an antinomy in capitalism’s basic structure, and this commits us to socialism.
