Aristotle's doctrine of the mean is expressed in quantitative terms, but this has been hard for some people to take literally, its more elaborate versions sometimes being described as “extremely silly.” Roughly two books of the Nicomachean Ethics are permeated with talk of character traits which are either deficient or excessive, however, and the aim of this paper is to examine how the doctrine might meet the objections of its critics.

It is sometimes claimed that Aristotle’s doctrine of the Mean is false or unhelpful: moral virtues are not typically flanked by two opposing vices as he claimed. However, an explicit restatement of Aristotle’s view in terms of sufficiency for an objective reveals that the Mean is more widely applicable than has sometimes been alleged. Understood as a special case of sufficiency, it is essential to many judgments of right and wrong. I consider some objections by Rosalind Hursthouse to Aristotle’s theory (...) and argue that they are based on a misunderstanding. However, there is indeed a tension in Aristotle’s view of goodness, hinted at in his claim that the good is "said in many ways". (shrink)

Aristotle's theory of a virtuous Mean, or mesotēs, has a range of application that is widely underestimated. A Mean, stripped of extraneous properties, is best thought of as a case of goal-oriented goodness. Contrary to what many commentators assume, it need not be objectionably quantitative. The theory of the Mean applies to both acts and dispositions. It is not restricted to intermediate states of feeling or emotion, and it can cover many cases of obligation. It deserves to be rehabilitated, since (...) the failure to grasp its structure leads to frequent confusions in everyday criticism. (shrink)

Aristotle’s doctrine of the mean states that each moral virtue stands opposed to two types of vice: one of excess and one of deficiency, respectively. Critics claim that some virtues—like honesty, fair-mindedness, and patience—are counterexamples to Aristotle’s doctrine. Here, I develop a generalizable strategy to defend the doctrine of the mean against such counterexamples. I argue that not only is the doctrine of the mean defensible, but taking it seriously also allows us to gain substantial insight into particular virtues. Failure (...) to take the doctrine seriously, moreover, exposes us to the risk of mistaking certain vices for virtues. (shrink)
