THIRD ARTICLE [II-II, Q. 55, Art. 3]

Whether Craftiness Is a Special Sin?

Objection 1: It would seem that craftiness is not a special sin. For

the words of Holy Writ do not induce anyone to sin; and yet they

induce us to be crafty, according to Prov. 1:4, "To give craftiness

[Douay: 'subtlety'] to little ones." Therefore craftiness is not a

sin.

Obj. 2: Further, it is written (Prov. 13:16): "The crafty [Douay:

'prudent'] man doth all things with counsel." Therefore, he does so

either for a good or for an evil end. If for a good end, there is no

sin seemingly, and if for an evil end, it would seem to pertain to

carnal or worldly prudence. Therefore craftiness is not a special sin

distinct from prudence of the flesh.

Obj. 3: Further, Gregory expounding the words of Job 12, "The

simplicity of the just man is laughed to scorn," says (Moral. x, 29):

"The wisdom of this world is to hide one's thoughts by artifice, to

conceal one's meaning by words, to represent error as truth, to make

out the truth to be false," and further on he adds: "This prudence is

acquired by the young, it is learnt at a price by children." Now the

above things seem to belong to craftiness. Therefore craftiness is not

distinct from carnal or worldly prudence, and consequently it seems

not to be a special sin.

_On the contrary,_ The Apostle says (2 Cor. 4:2): "We renounce the

hidden things of dishonesty, not walking in craftiness, nor

adulterating the word of God." Therefore craftiness is a sin.

_I answer that,_ Prudence is _right reason applied to action,_ just

as science is _right reason applied to knowledge._ In speculative

matters one may sin against rectitude of knowledge in two ways: in

one way when the reason is led to a false conclusion that appears to

be true; in another way when the reason proceeds from false premises,

that appear to be true, either to a true or to a false conclusion.

Even so a sin may be against prudence, through having some

resemblance thereto, in two ways. First, when the purpose of the

reason is directed to an end which is good not in truth but in

appearance, and this pertains to prudence of the flesh; secondly,

when, in order to obtain a certain end, whether good or evil, a man

uses means that are not true but fictitious and counterfeit, and this

belongs to the sin of craftiness. This is consequently a sin opposed

to prudence, and distinct from prudence of the flesh.

Reply Obj. 1: As Augustine observes (Contra Julian. iv, 3) just as

prudence is sometimes improperly taken in a bad sense, so is

craftiness sometimes taken in a good sense, and this on account of

their mutual resemblance. Properly speaking, however, craftiness is

taken in a bad sense, as the Philosopher states in _Ethic._ vi, 12.

Reply Obj. 2: Craftiness can take counsel both for a good end and for

an evil end: nor should a good end be pursued by means that are false

and counterfeit but by such as are true. Hence craftiness is a sin if

it be directed to a good end.

Reply Obj. 3: Under "worldly prudence" Gregory included everything

that can pertain to false prudence, so that it comprises craftiness

also.
