THIRD ARTICLE [I-II, Q. 57, Art. 3]

Whether the Intellectual Habit, Art, Is a Virtue?

Objection 1: It would seem that art is not an intellectual virtue.

For Augustine says (De Lib. Arb. ii, 18, 19) that "no one makes bad

use of virtue." But one may make bad use of art: for a craftsman can

work badly according to the knowledge of his art. Therefore art is

not a virtue.

Obj. 2: Further, there is no virtue of a virtue. But "there is a

virtue of art," according to the Philosopher (Ethic. vi, 5).

Therefore art is not a virtue.

Obj. 3: Further, the liberal arts excel the mechanical arts. But just

as the mechanical arts are practical, so the liberal arts are

speculative. Therefore, if art were an intellectual virtue, it would

have to be reckoned among the speculative virtues.

_On the contrary,_ The Philosopher (Ethic. vi, 3, 4) says that art is

a virtue; and yet he does not reckon it among the speculative

virtues, which, according to him, reside in the scientific part of

the soul.

_I answer that,_ Art is nothing else but "the right reason about

certain works to be made." And yet the good of these things depends,

not on man's appetitive faculty being affected in this or that way,

but on the goodness of the work done. For a craftsman, as such, is

commendable, not for the will with which he does a work, but for the

quality of the work. Art, therefore, properly speaking, is an

operative habit. And yet it has something in common with the

speculative habits: since the quality of the object considered by the

latter is a matter of concern to them also, but not how the human

appetite may be affected towards that object. For as long as the

geometrician demonstrates the truth, it matters not how his

appetitive faculty may be affected, whether he be joyful or angry:

even as neither does this matter in a craftsman, as we have observed.

And so art has the nature of a virtue in the same way as the

speculative habits, in so far, to wit, as neither art nor speculative

habit makes a good work as regards the use of the habit, which is the

property of a virtue that perfects the appetite, but only as regards

the aptness to work well.

Reply Obj. 1: When anyone endowed with an art produces bad

workmanship, this is not the work of that art, in fact it is contrary

to the art: even as when a man lies, while knowing the truth, his

words are not in accord with his knowledge, but contrary thereto.

Wherefore, just as science has always a relation to good, as stated

above (A. 2, ad 3), so it is with art: and it is for this reason that

it is called a virtue. And yet it falls short of being a perfect

virtue, because it does not make its possessor to use it well; for

which purpose something further is requisite: although there cannot

be a good use without the art.

Reply Obj. 2: In order that man may make good use of the art he has,

he needs a good will, which is perfected by moral virtue; and for

this reason the Philosopher says that there is a virtue of art;

namely, a moral virtue, in so far as the good use of art requires a

moral virtue. For it is evident that a craftsman is inclined by

justice, which rectifies his will, to do his work faithfully.

Reply Obj. 3: Even in speculative matters there is something by way

of work: e.g. the making of a syllogism or of a fitting speech, or

the work of counting or measuring. Hence whatever habits are ordained

to such like works of the speculative reason, are, by a kind of

comparison, called arts indeed, but "liberal" arts, in order to

distinguish them from those arts that are ordained to works done by

the body, which arts are, in a fashion, servile, inasmuch as the body

is in servile subjection to the soul, and man, as regards his soul,

is free (_liber_). On the other hand, those sciences which are not

ordained to any such like work, are called sciences simply, and not

arts. Nor, if the liberal arts be more excellent, does it follow that

the notion of art is more applicable to them.
