The paper asserts that the post-modern rejection of “modern” theoretical accounts including ethical-theoretical accounts as unacceptable meta-narratives would concur with an Aristotelian critique of contemporary ethical theories. Hence and Aristotelian critique will be similar to a post-modern critique. The paper sketches an account of what post-modernism in philosophy is and shows its similarity to Aristoteleanism in rejecting “modern” approaches in a significant way since an Aristotelian approach uses different criteria for what counts as ethical knowledge. The paper suggests that if one follows the lead of Aristotle outlined in Book One Chapter Three of the Nichomachean Ethics applied ethics can be seen as similar to what Aristotle called “Rhetoric,” for in the Rhetoric Aristotle shows how one should engage in discourse about issues of the just and the good. The final section addresses the problem of how an Aristotelian approach can avoid the relativism of post-modernism.
