 The theory of the mean is open to several objections, but before considering them, we should recognize that in fact there are two distinct theses each of which might be called a doctrine of the mean. First, there is the thesis that every virtue is a state that lies between two vices, one of excess and the other of deficiency. Second, there is the idea that whenever a virtuous person chooses to perform a virtuous act, he can be described as aiming at an act that is in some way or other intermediate between alternatives that he rejects. It is this second thesis that is most likely to be found objectionable. A critic might concede that in some cases virtuous acts can be described in Aristotle’s terms. If, for example, one is trying to decide how much to spend on a wedding present, one is looking for an amount that is neither excessive nor deficient. But surely many other problems that confront a virtuous agent are not susceptible to this quantitative analysis. If one must decide whether to attend a wedding or respect a competing obligation instead, it would not be illuminating to describe this as a search for a mean between extremes—unless “aiming at the mean” simply becomes another phrase for trying to make the right decision. The objection, then, is that Aristotle’s doctrine of the mean, taken as a doctrine about what the ethical agent does when he deliberates, is in many cases inapplicable or unilluminating.
