According to a widespread view, Kant's claim that moral wrongness has its ground in a contradiction underlying every immoral action is a “bluff” rooted in “dogmatic moralism”. Ever since Benjamin Constant's exchange with Kant, counterexamples have played a crucial role in showing why Kant's “universalization procedure” fails to determine the moral validity of our judgments. Despite recent attempts to bring Kant's ethics closer to Aristotle's, these counterexamples have prevailed. Most recently, Jesse Prinz has launched another attack along the same lines. (...) Prinz insists that Kant's universalization procedure fundamentally begs the question and fails to generate plausible results. Even authors who are very sympathetic to Kant, such as Allen Wood, have tried to downplay universalization, focusing instead on other formulations of the categorical imperative. In this paper, I respond directly to four of the most prominent counterexamples. In each case, I aim to show how we can uphold Kant's fundamental claim that the universal law formulation of the categorical imperative articulates the form of our particular moral judgments. (shrink)
