Now mean and mediocrity may be differently understood. For there is one mean which is compounded and made up of the two simple extremes, as in colors, gray, of white and black; and another, where that which contains and is contained is the medium between the containing and the contained, as, for instance, the number eight, between twelve and four. And a third sort there is also, which participates of neither extreme, as for example, all those things which, as being neither good nor evil in themselves, we call adiaphorous, or indifferent. But in none of these ways can virtue be said to be a mean, or mediocrity. For neither is it a mixture of vices, nor, comprehending that which is defective and short, is it comprehended by that which runs out into excess; nor yet is it exempt from the impetuosity and sudden efforts of the passions, in which excess and defect do properly take place. But moral virtue properly doth consist in a mean or mediocrity (and so it is commonly taken), most like to that which there is in our Greek music and harmony. For, whereas there are the highest and lowest musical notes in the extremities of the scale called nete and hypate; so likewise is there in the middle thereof, between these two, another musical note, and that the sweetest of all, called mese (or mean), which does as perfectly avoid the extreme sharpness of the one as it doth the over-flatness of the other. And so also virtue, being a motion and power which is exercised about the brutal and irrational part of the soul, takes away the remission and intention—in a word, the excess and defect—of the appetites, reducing thereby every one of the passions to a due mediocrity and perfect state of rectitude.
