On the contrary, The Philosopher says (Ethic. x, 4) that "no one takes pleasure according to time."
I answer that, A thing may be in time in two ways: first, by itself; secondly, by reason of something else, and accidentally as it were. For since time is the measure of successive things, those things are of themselves said to be in time, to which succession or something pertaining to succession is essential: such are movement, repose, speech and such like. On the other hand, those things are said to be in time, by reason of something else and not of themselves, to which succession is not essential, but which are subject to something successive. Thus the fact of being a man is not essentially something successive; since it is not a movement, but the term of a movement or change, viz. of this being begotten: yet, because human being is subject to changeable causes, in this respect, to be a man is in time.
Accordingly, we must say that delight, of itself indeed, is not in time: for it regards good already gained, which is, as it were, the term of the movement. But if this good gained be subject to change, the delight therein will be in time accidentally: whereas if it be altogether unchangeable, the delight therein will not be in time, either by reason of itself or accidentally.
Reply to Objection 1: As stated in De Anima iii, 7, movement is twofold. One is "the act of something imperfect, i.e. of something existing in potentiality, as such": this movement is successive and is in time. Another movement is "the act of something perfect, i.e. of something existing in act," e.g. to understand, to feel, and to will and such like, also to have delight. This movement is not successive, nor is it of itself in time.
Reply to Objection 2: Delight is said to be long lasting or morose, according as it is accidentally in time.
Reply to Objection 3: Other passions have not for their object a good obtained, as delight has. Wherefore there is more of the movement of the imperfect in them than in delight. And consequently it belongs more to delight not to be in time.
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.
Objection 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.
Objection 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 to Objection 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 to Objection 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 to Objection 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.
Whether delight is in the intellectual appetite?
Objection 1: It would seem that delight is not in the intellectual appetite. Because the Philosopher says (Rhet. i, 11) that "delight is a sensible movement." But sensible movement is not in an intellectual power. Therefore delight is not in the intellectual appetite.
Objection 2: Further, delight is a passion. But every passion is in the sensitive appetite. Therefore delight is only in the sensitive appetite.
Objection 3: Further, delight is common to us and to the irrational animals. Therefore it is not elsewhere than in that power which we have in common with irrational animals.
On the contrary, It is written ( Ps. 36:4 ): "Delight in the Lord." But the sensitive appetite cannot reach to God; only the intellectual appetite can. Therefore delight can be in the intellectual appetite.
I answer that, As stated above (A[3]), a certain delight arises from the apprehension of the reason. Now on the reason apprehending something, not only the sensitive appetite is moved, as regards its application to some particular thing, but also the intellectual appetite, which is called the will. And accordingly in the intellectual appetite or will there is that delight which is called joy, but not bodily delight.
However, there is this difference of delight in either power, that delight of the sensitive appetite is accompanied by a bodily transmutation, whereas delight of the intellectual appetite is nothing but the mere movement of the will. Hence Augustine says (De Civ. Dei xiv, 6) that "desire and joy are nothing else but a volition of consent to the things we wish."
Reply to Objection 1: In this definition of the Philosopher, he uses the word "sensible" in its wide acceptation for any kind of perception. For he says (Ethic. x, 4) that "delight is attendant upon every sense, as it is also upon every act of the intellect and contemplation." Or we may say that he is defining delight of the sensitive appetite.
Reply to Objection 2: Delight has the character of passion, properly speaking, when accompanied by bodily transmutation. It is not thus in the intellectual appetite, but according to simple movement: for thus it is also in God and the angels. Hence the Philosopher says (Ethic. vii, 14) that "God rejoices by one simple act": and Dionysius says at the end of De Coel. Hier., that "the angels are not susceptible to our passible delight, but rejoice together with God with the gladness of incorruption."
