THIRD ARTICLE [I-II, Q. 31, Art. 3]

Whether Delight Differs from Joy?

Objection 1: It would seem that delight is altogether the same as

joy. Because the passions of the soul differ according to their

objects. But delight and joy have the same object, namely, a good

obtained. Therefore joy is altogether the same as delight.

Obj. 2: Further, one movement does not end in two terms. But one and

the same movement, that of desire, ends in joy and delight. Therefore

delight and joy are altogether the same.

Obj. 3: Further, if joy differs from delight, it seems that there is

equal reason for distinguishing gladness, exultation, and

cheerfulness from delight, so that they would all be various passions

of the soul. But this seems to be untrue. Therefore joy does not

differ from delight.

_On the contrary,_ We do not speak of joy in irrational animals;

whereas we do speak of delight in them. Therefore joy is not the same

as delight.

_I answer that,_ Joy, as Avicenna states (De Anima iv), is a kind of

delight. For we must observe that, just as some concupiscences are

natural, and some not natural, but consequent to reason, as stated

above (Q. 30, A. 3), so also some delights are natural, and some are

not natural but rational. Or, as Damascene (De Fide Orth. ii, 13) and

Gregory of Nyssa [*Nemesius, De Nat. Hom. xviii.] put it, "some

delights are of the body, some are of the soul"; which amounts to the

same. For we take delight both in those things which we desire

naturally, when we get them, and in those things which we desire as a

result of reason. But we do not speak of joy except when delight

follows reason; and so we do not ascribe joy to irrational animals,

but only delight.

Now whatever we desire naturally, can also be the object of reasoned

desire and delight, but not vice versa. Consequently whatever can be

the object of delight, can also be the object of joy in rational

beings. And yet everything is not always the object of joy; since

sometimes one feels a certain delight in the body, without rejoicing

thereat according to reason. And accordingly delight extends to more

things than does joy.

Reply Obj. 1: Since the object of the appetite of the soul is an

apprehended good, diversity of apprehension pertains, in a way, to

diversity of the object. And so delights of the soul, which are also

called joys, are distinct from bodily delights, which are not called

otherwise than delights: as we have observed above in regard to

concupiscences (Q. 30, A. 3, ad 2).

Reply Obj. 2: A like difference is to be observed in concupiscences

also: so that delight corresponds to concupiscence, while joy

corresponds to desire, which seems to pertain more to concupiscence

of the soul. Hence there is a difference of repose corresponding to

the difference of movement.

Reply Obj. 3: These other names pertaining to delight are derived

from the effects of delight; for _laetitia_ (gladness) is derived

from the "dilation" of the heart, as if one were to say "latitia";

"exultation" is derived from the exterior signs of inward delight,

which appear outwardly in so far as the inward joy breaks forth from

its bounds; and "cheerfulness" is so called from certain special

signs and effects of gladness. Yet all these names seem to belong to

joy; for we do not employ them save in speaking of rational beings.
