, has no place in perfect men.
Yet a certain guile is to be found in them, according to 2 Cor.
12:16, "Being crafty I caught you by guile." Therefore guile is not
always a sin.

Obj. 2: Further, guile seems to pertain chiefly to the tongue,
according to Ps. 5:11, "They dealt deceitfully with their tongues."
Now craftiness like prudence is in the very act of reason. Therefore
guile does not pertain to craftiness.

Obj. 3: Further, it is written (Prov. 12:20): "Guile [Douay:
'Deceit'] is in the heart of them that think evil things." But the
thought of evil things does not always pertain to craftiness.
Therefore guile does not seem to belong to craftiness.

_On the contrary,_ Craftiness aims at lying in wait, according to
Eph. 4:14, "By cunning craftiness by which they lie in wait to
deceive": and guile aims at this also. Therefore guile pertains to
craftiness.

_I answer that,_ As stated above (A. 3), it belongs to craftiness to
adopt ways that are not true but counterfeit and apparently true, in
order to attain some end either good or evil. Now the adopting of
such ways may be subjected to a twofold consideration; first, as
regards the process of thinking them out, and this belongs properly
to craftiness, even as thinking out right ways to a due end belongs
to prudence. Secondly the adopting of such like ways may be
considered with regard to their actual execution, and in this way it
belongs to guile. Hence guile denotes a certain execution of
craftiness, and accordingly belongs thereto.

Reply Obj. 1: Just as craftiness is taken properly in a bad sense,
and improperly in a good sense, so too is guile which is the
execution of craftiness.

Reply Obj. 2: The execution of craftiness with the purpose of
deceiving, is effected first and foremost by words, which hold the
chief place among those signs whereby a man signifies something to
another man, as Augustine states (De Doctr. Christ. ii, 3), hence
guile is ascribed chiefly to speech. Yet guile may happen also in
deeds, according to Ps. 104:25, "And to deal deceitfully with his
servants." Guile is also in the heart, according to Ecclus. 19:23,
"His interior is full of deceit," but this is to devise deceits,
according to Ps. 37:13: "They studied deceits all the day long."

Reply Obj. 3: Whoever purposes to do some evil deed, must needs
devise certain ways of attaining his purpose, and for the most part
he devises deceitful ways, whereby the more easily to obtain h
