Book 2
7
These then, to sum up the matter, are the precautions that will best enable us to hit the mean. But no doubt it is a difficult thing to do, and especially in particular cases: for instance, it is not easy to define in what manner and with what people and on what sort of grounds and how long one ought to be angry; and in fact we sometimes praise men who err on the side of defect in this matter and call them gentle, sometimes those who are quick to a anger and style them manly.
8
However, we do not blame one who diverges a little from the right course, whether on the side of the too much or of the too little, but one who diverges more widely, for his error is noticed. Yet to what degree and how seriously a man must err to be blamed is not easy to define on principle. For in fact no object of perception is easy to define; and such questions of degree depend on particular circumstances, and the decision lies with perception.

Thus much then is clear, that it is the middle disposition in each department of conduct that is to be praised, but that one should lean sometimes to the side of excess and sometimes to that of deficiency, since this is the easiest way of hitting the mean and the right course.
