We moderns tend to focus on numerous reasons for ethical failure—so-called moral luck, moral dilemmas, moral tragedy, perverse incentives—, matters that Aristotle largely ignores. Aristotle focuses instead on ethical success at the species level. However, ethical success may not be as achievable as Aristotle assumes. This paper considers numerous reasons for thinking that Aristotle’s theory of virtue ethics, a theory centered on human excellences realized through practices inextricably bound to the larger world of politics, would need to be revised substantially to be applicable to modern corporate life and work. Modifying the theory is itself problematic on numerous scores, and Aristotle’s theory may lack the resources for adequately addressing these reasons.
