 Perhaps a greater difficulty can be raised if we ask how Aristotle determines which emotions are governed by the doctrine of the mean. Consider someone who loves to wrestle, for example. Is this passion something that must be felt by every human being at appropriate times and to the right degree? Surely someone who never felt this emotion to any degree could still live a perfectly happy life. Why then should we not say the same about at least some of the emotions that Aristotle builds into his analysis of the ethically virtuous agent? Why should we experience anger at all, or fear, or the degree of concern for wealth and honor that Aristotle commends? These are precisely the questions that were asked in antiquity by the Stoics, and they came to the conclusion that such common emotions as anger and fear are always inappropriate. Aristotle assumes, on the contrary, not simply that these common passions are sometimes appropriate, but that it is essential that every human being learn how to master them and experience them in the right way at the right times. A defense of his position would have to show that the emotions that figure in his account of the virtues are valuable components of any well-lived human life, when they are experienced properly. Perhaps such a project could be carried out, but Aristotle himself does not attempt to do so.
