Editorial note — Page 411 CHAPTER XV

[Footnote 2: "But the virtues we acquire by first exercising them, as is the case with all the arts, for it is by doing what we ought to do when we have learned the arts, that we learn the arts themselves; we become, e.g. builders by building, and harpists by playing the harp. Similarly it is by doing just acts that we become just, by doing temperate acts that we become temperate, by doing courageous acts that we become courageous.... Again the causes and means by which any virtue is produced, and by which it is destroyed, are the same; and it is equally so with any art; for it is by playing the harp that both good and bad harpists are produced, and the case of builders and all other artisans is similar, as it is by building well that they will be good builders, and by building badly that they will be bad builders.... It is by acting in such transactions as take place between man and man that we become either just or unjust. It is by acting in the face of danger and habituating ourselves to fear or courage that we become either cowardly or courageous. It is much the same with our desires and angry passions. Some people become temperate and gentle, others become licentious and passionate, according as they conduct themselves in one way or another way in particular circumstances." (Aristotle: Ethics, pp. 35-36, Weldon translation.)]
