It is expedient, because it brings about things of such a kind that by their occurrence we are benefited. It is binding, because it causes unity where unity is needed; profitable, because it defrays what is expended on it, so that the return yields a balance of benefit on the transaction. It is useful, because it secures the use of benefit; it is serviceable, because the utility it affords is worthy of all praise. It is beautiful, because the good is proportionate to the use made of it; beneficial, because by its inherent nature it benefits; choiceworthy, because it is such that to choose it is reasonable. It is also just or right, inasmuch as it is in harmony with law and tends to draw men together.

The reason why they characterize the perfect good as beautiful is that it has in full all the factors required by nature or has perfect proportion. Of the beautiful there are (say they) four species, namely, what is just, courageous, orderly and wise; for it is under these forms that fair deeds are accomplished. Similarly there are four species of the base or ugly, namely, what is unjust, cowardly, disorderly, and unwise. By the beautiful is meant properly and in an unique sense that good which renders its possessors praiseworthy, or briefly, good which is worthy of praise; though in another sense it signifies a good aptitude for one’s proper function; while in yet another sense the beautiful is that which lends new grace to anything, as when we say of the wise man that he alone is good and beautiful.
