ore folly is not a sin.

_On the contrary,_ It is written (Prov. 1:32): "The prosperity of
fools shall destroy them." But no man is destroyed save for sin.
Therefore folly is a sin.

_I answer that,_ Folly, as stated above (A. 1), denotes dullness of
sense in judging, and chiefly as regards the highest cause, which is
the last end and the sovereign good. Now a man may in this respect
contract dullness in judgment in two ways. First, from a natural
indisposition, as in the case of idiots, and such like folly is no
sin. Secondly, by plunging his sense into earthly things, whereby his
sense is rendered incapable of perceiving Divine things, according to
1 Cor. 2:14, "The sensual man perceiveth not these things that are of
the Spirit of God," even as sweet things have no savor for a man
whose taste is infected with an evil humor: and such like folly is a
sin.

This suffices for the Reply to the First Objection.

Reply Obj. 2: Though no man wishes to be a fool, yet he wishes those
things of which folly is a consequence, viz. to withdraw his sense
from spiritual things and to plunge it into earthly things. The same
thing happens in regard to other sins; for the lustful man desires
pleasure, without which there is no sin, although he does not desire
sin simply, for he would wish to enjoy the pleasure without sin.

Reply Obj. 3: Folly is opposed to the precepts about the
contemplation of truth, of which we have spoken above (Q. 16) when
we were treating of knowledge and understanding.

THIRD ARTICLE [II-II, Q. 46, Art. 3]

Whether Folly Is a Daughter of Lust?

Objection 1: It would seem that folly is not a daughter of lust. For
Gregory (Moral. xxxi, 45) enumerates the daughters of lust, among
which however he makes no mention of folly. Therefore folly does not
proceed from lust.

Obj. 2: Further, the Apostle says (1 Cor. 3:19): "The wisdom of this
world is foolishness with God." Now, according to Gregory (Moral. x,
29) "the wisdom of this world consists in covering the heart with
crafty devices;" and this savors of duplicity. Therefore folly is a
daughter of duplicity rather than of lust.

Obj. 3: Further, anger especially is the cause of fury and madness in
some persons; and this pertains to folly. Therefore folly arises from
anger rather than from lust.

_On the contrary,_ It is written (Prov. 7:22): "Immediately he
followeth her," i.e. the harlot . . . "not knowing that he is drawn
