[I-II.q.35.a.1.arg.1] It would seem that pain is not a passion of the soul. Because no passion of the soul is in the body. But pain can be in the body, since Augustine says (De Vera Relig. xii), that "bodily pain is a sudden corruption of the well-being of that thing which the soul, by making evil use of it, made subject to corruption." Therefore pain is not a passion of the soul.

[I-II.q.35.a.1.arg.2] Further, every passion of the soul belongs to the appetitive faculty. But pain does not belong to the appetitive, but rather to the apprehensive part: for Augustine says (De Nat. Boni xx) that "bodily pain is caused by the sense resisting a more powerful body." Therefore pain is not a passion of the soul.

[I-II.q.35.a.1.arg.3] Further, every passion of the soul belongs to the animal appetite. But pain does not belong to the animal appetite, but rather to the natural appetite; for Augustine says (Gen. ad lit. viii, 14): "Had not some good remained in nature, we should feel no pain in being punished by the loss of good." Therefore pain is not a passion of the soul.

[I-II.q.35.a.1.sc] Augustine (De Civ. Dei xiv, 8) reckons pain among the passions of the soul; quoting Virgil (Aeneid, vi, 733): "hence wild desires and grovelling fears/And human laughter, human tears." [Translation: Conington.]

[I-II.q.35.a.1.co] Just as two things are requisite for pleasure; namely, conjunction with good and perception of this conjunction; so also two things are requisite for pain: namely, conjunction with some evil (which is in so far evil as it deprives one of some good), and perception of this conjunction. Now whatever is conjoined, if it have not the aspect of good or evil in regard to the being to which it is conjoined, cannot cause pleasure or pain. Whence it is evident that something under the aspect of good or evil is the object of the pleasure or pain. But good and evil, as such, are objects of the appetite. Consequently it is clear that pleasure and pain belong to the appetite.

Now every appetitive movement or inclination consequent to apprehension, belongs to the intellective or sensitive appetite: since the inclination of the natural appetite is not consequent to an apprehension of the subject of that appetite, but to the apprehension of another, as stated in the I, 13, 1,3. Since then pleasure and pain presuppose some sense or apprehension in the same subject, it is evident that pain, like pleasure, is in the intellective or sensitive appetite.

Again every movement of the sensitive appetite is called a passion, as stated above (22, 1,3): and especially those which tend to some defect. Consequently pain, according as it is in the sensitive appetite, is most properly called a passion of the soul: just as bodily ailments are properly called passions of the body. Hence Augustine (De Civ. Dei xiv, 7,[8 [Quoting Cicero]) reckons pain especially as being a kind of ailment.

[I-II.q.35.a.1.ad.1] We speak of the body, because the cause of pain is in the body: as when we suffer something hurtful to the body. But the movement of pain is always in the soul; since "the body cannot feel pain unless the soul feel it," as Augustine says (Super Psalm 87:4).

[I-II.q.35.a.1.ad.2] We speak of pain of the senses, not as though it were an act of the sensitive power; but because the senses are required for bodily pain, in the same way as for bodily pleasure.

[I-II.q.35.a.1.ad.3] Pain at the loss of good proves the goodness of the nature, not because pain is an act of the natural appetite, but because nature desires something as good, the removal of which being perceived, there results the passion of pain in the sensitive appetite.

[I-II.q.35.a.2.arg.1] It would seem that sorrow is not pain. For Augustine says (De Civ. Dei xiv, 7) that "pain is used to express bodily suffering." But sorrow is used more in reference to the soul. Therefore sorrow is not pain.

[I-II.q.35.a.2.arg.2] Further, pain is only in respect of present evil. But sorrow can refer to both past and future evil: thus repentance is sorrow for the past, and anxiety for the future. Therefore sorrow is quite different from pain.

[I-II.q.35.a.2.arg.3] Further, pain seems not to follow save from the sense of touch. But sorrow can arise from all the senses. Therefore sorrow is not pain, and extends to more objects.

[I-II.q.35.a.2.sc] The Apostle says (Romans 9:2): "I have great sorrow [Douay: 'sadness'] and continual pain [Douay: 'sorrow'] in my heart," thus denoting the same thing by sorrow and pain.

[I-II.q.35.a.2.co] Pleasure and pain can arise from a twofold apprehension, namely, from the apprehension of an exterior sense; and from the interior apprehension of the intellect or of the imagination. Now the interior apprehension extends to more objects than the exterior apprehension: because whatever things come under the exterior apprehension, come under the interior, but not conversely. Consequently that pleasure alone which is caused by an interior apprehension is called joy, as stated above (Question 31, Article 3): and in like manner that pain alone which is caused by an interior apprehension, is called sorrow. And just as that pleasure which is caused by an exterior apprehension, is called pleasure but not joy; so too that pain which is caused by an exterior apprehension, is called pain indeed but not sorrow. Accordingly sorrow is a species of pain, as joy is a species of pleasure.

[I-II.q.35.a.2.ad.1] Augustine is speaking there of the use of the word: because "pain" is more generally used in reference to bodily pains, which are better known, than in reference to spiritual pains.

[I-II.q.35.a.2.ad.2] External sense perceives only what is present; but the interior cognitive power can perceive the present, past and future. Consequently sorrow can regard present, past and future: whereas bodily pain, which follows apprehension of the external sense, can only regard something present.

[I-II.q.35.a.2.ad.3] The sensibles of touch are painful, not only in so far as they are disproportionate to the apprehensive power, but also in so far as they are contrary to nature: whereas the objects of the other senses can indeed be disproportionate to the apprehensive power, but they are not contrary to nature, save as they are subordinate to the sensibles of touch. Consequently man alone, who is a perfectly cognizant animal, takes pleasure in the objects of the other senses for their own sake; whereas other animals take no pleasure in them save as referable to the sensibles of touch, as stated in Ethic. iii, 10. Accordingly, in referring to the objects of the other senses, we do not speak of pain in so far as it is contrary to natural pleasure: but rather of sorrow, which is contrary to joy. So then if pain be taken as denoting bodily pain, which is its more usual meaning, then it is contrasted with sorrow, according to the distinction of interior and exterior apprehension; although, on the part of the objects, pleasure extends further than does bodily pain. But if pain be taken in a wide sense, then it is the genus of sorrow, as stated above.

[I-II.q.35.a.3.arg.1] It would seem that sorrow is not contrary to pleasure. For one of two contraries is not the cause of the other. But sorrow can be the cause of pleasure; for it is written (Matthew 5:5): "Blessed are they that mourn, for they shall be comforted." Therefore they are not contrary to one another.

[I-II.q.35.a.3.arg.2] Further, one contrary does not denominate the other. But to some, pain or sorrow gives pleasure: thus Augustine says (Confess. iii, 2) that in stage-plays sorrow itself gives pleasure: and (Confess. iv, 5) that "weeping is a bitter thing, and yet it sometimes pleases us." Therefore pain is not contrary to pleasure.

[I-II.q.35.a.3.arg.3] Further, one contrary is not the matter of the other; because contraries cannot co-exist together. But sorrow can be the matter of pleasure; for Augustine says (De Poenit. xiii): "The penitent should ever sorrow, and rejoice in his sorrow." The Philosopher too says (Ethic. ix, 4) that, on the other hand, "the evil man feels pain at having been pleased." Therefore pleasure and pain are not contrary to one another.

[I-II.q.35.a.3.sc] Augustine says (De Civ. Dei xiv, 6) that "joy is the volition of consent to the things we wish: and that sorrow is the volition of dissent from the things we do not wish." But consent and dissent are contraries. Therefore pleasure and sorrow are contrary to one another.

[I-II.q.35.a.3.co] As the Philosopher says (Metaph. x, 4), contrariety is a difference in respect of a form. Now the form or species of a passion or movement is taken from the object or term. Consequently, since the objects of pleasure and sorrow or pain, viz. present good and present evil, are contrary to one another, it follows that pain and pleasure are contrary to one another.

[I-II.q.35.a.3.ad.1] Nothing hinders one contrary causing the other accidentally: and thus sorrow can be the cause of pleasure. In one way, in so far as from sorrow at the absence of something, or at the presence of its contrary, one seeks the more eagerly for something pleasant: thus a thirsty man seeks more eagerly the pleasure of a drink, as a remedy for the pain he suffers. In another way, in so far as, from a strong desire for a certain pleasure, one does not shrink from undergoing pain, so as to obtain that pleasure. In each of these ways, the sorrows of the present life lead us to the comfort of the future life. Because by the mere fact that man mourns for his sins, or for the delay of glory, he merits the consolation of eternity. In like manner a man merits it when he shrinks not from hardships and straits in order to obtain it.

[I-II.q.35.a.3.ad.2] Pain itself can be pleasurable accidentally in so far as it is accompanied by wonder, as in stage-plays; or in so far as it recalls a beloved object to one's memory, and makes one feel one's love for the thing, whose absence gives us pain. Consequently, since love is pleasant, both pain and whatever else results from love, forasmuch as they remind us of our love, are pleasant. And, for this reason, we derive pleasure even from pains depicted on the stage: in so far as, in witnessing them, we perceive ourselves to conceive a certain love for those who are there represented.

[I-II.q.35.a.3.ad.3] The will and the reason reflect on their own acts, inasmuch as the acts themselves of the will and reason are considered under the aspect of good or evil. In this way sorrow can be the matter of pleasure, or vice versa, not essentially but accidentally: that is, in so far as either of them is considered under the aspect of good or evil.

[I-II.q.35.a.5.arg.1] It would seem that there is a sorrow that is contrary to the pleasure of contemplation. For the Apostle says (2 Corinthians 7:10): "The sorrow that is according to God, worketh penance steadfast unto salvation." Now to look at God belongs to the higher reason, whose act is to give itself to contemplation, according to Augustine (De Trin. xii, 3,4). Therefore there is a sorrow contrary to the pleasure of contemplation.

[I-II.q.35.a.5.arg.2] Further, contrary things have contrary effects. If therefore the contemplation of one contrary gives pleasure, the other contrary will give sorrow: and so there will be a sorrow contrary to the pleasure of contemplation.

[I-II.q.35.a.5.arg.3] Further, as the object of pleasure is good, so the object of sorrow is evil. But contemplation can be an evil: since the Philosopher says (Metaph. xii, 9) that "it is unfitting to think of certain things." Therefore sorrow can be contrary to the pleasure of contemplation.

[I-II.q.35.a.5.arg.4] Further, any work, so far as it is unhindered, can be a cause of pleasure, as stated in Ethic. vii, 12,13; x, 4. But the work of contemplation can be hindered in many ways, either so as to destroy it altogether, or as to make it difficult. Therefore in contemplation there can be a sorrow contrary to the pleasure.

[I-II.q.35.a.5.arg.5] Further, affliction of the flesh is a cause of sorrow. But, as it is written (Ecclesiastes 12:12) "much study is an affliction of the flesh." Therefore contemplation admits of sorrow contrary to its pleasure.

[I-II.q.35.a.5.sc] It is written (Wisdom 8:16): "Her," i.e. wisdom's, "conversation hath no bitterness nor her company any tediousness; but joy and gladness." Now the conversation and company of wisdom are found in contemplation. Therefore there is no sorrow contrary to the pleasure of contemplation.

[I-II.q.35.a.5.co] The pleasure of contemplation can be understood in two ways. In one way, so that contemplation is the cause, but not the object of pleasure: and then pleasure is taken not in contemplating but in the thing contemplated. Now it is possible to contemplate something harmful and sorrowful, just as to contemplate something suitable and pleasant. Consequently if the pleasure of contemplation be taken in this way, nothing hinders some sorrow being contrary to the pleasure of contemplation.

In another way, the pleasure of contemplation is understood, so that contemplation is its object and cause; as when one takes pleasure in the very act of contemplating. And thus, according to Gregory of Nyssa [Nemesius, De Nat. Hom. xviii.], "no sorrow is contrary to that pleasure which is about contemplation": and the Philosopher says the same (Topic. i, 13; Ethic. x, 3). This, however, is to be understood as being the case properly speaking. The reason is because sorrow is of itself contrary to pleasure in a contrary object: thus pleasure in heat is contrary to sorrow caused by cold. But there is no contrary to the object of contemplation: because contraries, as apprehended by the mind, are not contrary, but one is the means of knowing the other. Wherefore, properly speaking, there cannot be a sorrow contrary to the pleasure of contemplation. Nor has it any sorrow annexed to it, as bodily pleasures have, which are like remedies against certain annoyances; thus a man takes pleasure in drinking through being troubled with thirst, but when the thirst is quite driven out, the pleasure of drinking ceases also. Because the pleasure of contemplation is not caused by one's being quit of an annoyance, but by the fact that contemplation is pleasant in itself: for pleasure is not a "becoming" but a perfect operation, as stated above (Question 31, Article 1).

Accidentally, however, sorrow is mingled with the pleasure of contemplation; and this in two ways: first, on the part of an organ, secondly, through some impediment in the apprehension. On the part of an organ, sorrow or pain is mingled with apprehension, directly, as regards the apprehensive powers of the sensitive part, which have a bodily organ; either from the sensible object disagreeing with the normal condition of the organ, as the taste of something bitter, and the smell of something foul; or from the sensible object, though agreeable, being so continuous in its action on the sense, that it exceeds the normal condition of the organ, as stated above (Question 33, Article 2), the result being that an apprehension which at first was pleasant becomes tedious. But these two things cannot occur directly in the contemplation of the mind; because the mind has no corporeal organ: wherefore it was said in the authority quoted above that intellectual contemplation has neither "bitterness," nor "tediousness." Since, however, the human mind, in contemplation, makes use of the sensitive powers of apprehension, to whose acts weariness is incidental; therefore some affliction or pain is indirectly mingled with contemplation.

Nevertheless, in neither of these ways, is the pain thus accidentally mingled with contemplation, contrary to the pleasure thereof. Because pain caused by a hindrance to contemplation, is not contrary to the pleasure of contemplation, but rather is in affinity and in harmony with it, as is evident from what has been said above (Article 4): while pain or sorrow caused by bodily weariness, does not belong to the same genus, wherefore it is altogether disparate. Accordingly it is evident that no sorrow is contrary to pleasure taken in the very act of contemplation; nor is any sorrow connected with it save accidentally.

[I-II.q.35.a.5.ad.1] The "sorrow which is according to God," is not caused by the very act of intellectual contemplation, but by something which the mind contemplates: viz. by sin, which the mind considers as contrary to the love of God.

[I-II.q.35.a.5.ad.2] Things which are contrary according to nature are not contrary according as they exist in the mind: for things that are contrary in reality are not contrary in the order of thought; indeed rather is one contrary the reason for knowing the other. Hence one and the same science considers contraries.

[I-II.q.35.a.5.ad.3] Contemplation, in itself, is never evil, since it is nothing else than the consideration of truth, which is the good of the intellect: it can, however, be evil accidentally, i.e. in so far as the contemplation of a less noble object hinders the contemplation of a more noble object; or on the part of the object contemplated, to which the appetite is inordinately attached.

[I-II.q.35.a.5.ad.4] Sorrow caused by a hindrance to contemplation, is not contrary to the pleasure of contemplation, but is in harmony with it, as stated above.

[I-II.q.35.a.5.ad.5] Affliction of the flesh affects contemplation accidentally and indirectly, as stated above.

[I-II.q.35.a.6.arg.2] Further, the action of a contrary conduces to rapidity and intensity of movement: for "hot water freezes quicker and harder," as the Philosopher says (Meteor. i, 12). But the shunning of sorrow is due to the contrariety of the cause of sorrow; whereas the desire for pleasure does not arise from any contrariety, but rather from the suitableness of the pleasant object. Therefore sorrow is shunned more eagerly than pleasure is sought.

[I-II.q.35.a.6.arg.3] Further, the stronger the passion which a man resists according to reason, the more worthy is he of praise, and the more virtuous: since "virtue is concerned with the difficult and the good" (Ethic. ii, 3). But the brave man who resists the movement of shunning sorrow, is more virtuous than the temperate man, who resists the movement of desire for pleasure: since the Philosopher says (Rhet. ii, 4) that "the brave and the just are chiefly praised." Therefore the movement of shunning sorrow is more eager than the movement of seeking pleasure.

[I-II.q.35.a.6.sc] Good is stronger than evil, as Dionysius declares (Div. Nom. iv). But pleasure is desirable for the sake of the good which is its object; whereas the shunning of sorrow is on account of evil. Therefore the desire for pleasure is more eager than the shunning of sorrow.

[I-II.q.35.a.6.co] The desire for pleasure is of itself more eager than the shunning of sorrow. The reason of this is that the cause of pleasure is a suitable good; while the cause of pain or sorrow is an unsuitable evil. Now it happens that a certain good is suitable without any repugnance at all: but it is not possible for any evil to be so unsuitable as not to be suitable in some way. Wherefore pleasure can be entire and perfect: whereas sorrow is always partial. Therefore desire for pleasure is naturally greater than the shunning of sorrow. Another reason is because the good, which is the object of pleasure, is sought for its own sake: whereas the evil, which is the object of sorrow, is to be shunned as being a privation of good: and that which is by reason of itself is stronger than that which is by reason of something else. Moreover we find a confirmation of this in natural movements. For every natural movement is more intense in the end, when a thing approaches the term that is suitable to its nature, than at the beginning, when it leaves the term that is unsuitable to its nature: as though nature were more eager in tending to what is suitable to it, than in shunning what is unsuitable. Therefore the inclination of the appetitive power is, of itself, more eager in tending to pleasure than in shunning sorrow.

But it happens accidentally that a man shuns sorrow more eagerly than he seeks pleasure: and this for three reasons. First, on the part of the apprehension. Because, as Augustine says (De Trin. x, 12), "love is felt more keenly, when we lack that which we love." Now from the lack of what we love, sorrow results, which is caused either by the loss of some loved good, or by the presence of some contrary evil. But pleasure suffers no lack of the good loved, for it rests in possession of it. Since then love is the cause of pleasure and sorrow, the latter is more the shunned, according as love is the more keenly felt on account of that which is contrary to it. Secondly, on the part of the cause of sorrow or pain, which cause is repugnant to a good that is more loved than the good in which we take pleasure. For we love the natural well-being of the body more than the pleasure of eating: and consequently we would leave the pleasure of eating and the like, from fear of the pain occasioned by blows or other such causes, which are contrary to the well-being of the body. Thirdly, on the part of the effect: namely, in so far as sorrow hinders not only one pleasure, but all.

[I-II.q.35.a.6.ad.1] The saying of Augustine that "sorrow is shunned more than pleasure is sought" is true accidentally but not simply. And this is clear from what he says after: "Since we see that the most savage animals are deterred from the greatest pleasures by fear of pain," which pain is contrary to life which is loved above all.

[I-II.q.35.a.6.ad.2] It is not the same with movement from within and movement from without. For movement from within tends to what is suitable more than it recedes from that which is unsuitable; as we remarked above in regard to natural movement. But movement from without is intensified by the very opposition: because each thing strives in its own way to resist anything contrary to it, as aiming at its own preservation. Hence violent movement is intense at first, and slackens towards the end. Now the movement of the appetitive faculty is from within: since it tends from the soul to the object. Consequently pleasure is, of itself, more to be sought than sorrow is to be shunned. But the movement of the sensitive faculty is from without, as it were from the object of the soul. Consequently the more contrary a thing is the more it is felt. And then too, accidentally, in so far as the senses are requisite for pleasure and pain, pain is shunned more than pleasure is sought.

[I-II.q.35.a.6.ad.3] A brave man is not praised because, in accordance with reason, he is not overcome by any kind of sorrow or pain whatever, but because he is not overcome by that which is concerned with the dangers of death. And this kind of sorrow is more shunned, than pleasures of the table or of sexual intercourse are sought, which latter pleasures are the object of temperance: thus life is loved more than food and sexual pleasure. But the temperate man is praised for refraining from pleasures of touch, more than for not shunning the pains which are contrary to them, as is stated in Ethic. iii, 11.

[I-II.q.35.a.7.arg.1] It would seem that outward pain is greater than interior sorrow of the heart. Because outward pain arises from a cause repugnant to the well-being of the body in which is life: whereas interior sorrow is caused by some evil in the imagination. Since, therefore, life is loved more than an imagined good, it seems that, according to what has been said above (Article 6), outward pain is greater than interior sorrow.

[I-II.q.35.a.7.arg.2] Further, the reality moves more than its likeness does. But outward pain arises from the real conjunction of some contrary; whereas inward sorrow arises from the apprehended likeness of a contrary. Therefore outward pain is greater than inward sorrow.

[I-II.q.35.a.7.arg.3] Further, a cause is known by its effect. But outward pain has more striking effects: since man dies sooner of outward pain than of interior sorrow. Therefore outward pain is greater and is shunned more than interior sorrow.

[I-II.q.35.a.7.sc] it is written (Sirach 25:17): "The sadness of the heart is every wound [Douay: 'plague'], and the wickedness of a woman is all evil." Therefore, just as the wickedness of a woman surpasses all other wickedness, as the text implies; so sadness of the heart surpasses every outward wound.

[I-II.q.35.a.7.co] Interior and exterior pain agree in one point and differ in two. They agree in this, that each is a movement of the appetitive power, as stated above (Article 1). But they differ in respect of those two things which are requisite for pain and pleasure; namely, in respect of the cause, which is a conjoined good or evil; and in respect of the apprehension. For the cause of outward pain is a conjoined evil repugnant to the body; while the cause of inward pain is a conjoined evil repugnant to the appetite. Again, outward pain arises from an apprehension of sense, chiefly of touch; while inward pain arises from an interior apprehension, of the imagination or of the reason.

If then we compare the cause of inward pain to the cause of outward pain, the former belongs, of itself, to the appetite to which both these pains belong: while the latter belongs to the appetite directly. Because inward pain arises from something being repugnant to the appetite itself, while outward pain arises from something being repugnant to the appetite, through being repugnant to the body. Now, that which is of itself is always prior to that which is by reason of another. Wherefore, from this point of view, inward pain surpasses outward pain. In like manner also on the part of apprehension: because the apprehension of reason and imagination is of a higher order than the apprehension of the sense of touch. Consequently inward pain is, simply and of itself, more keen than outward pain: a sign whereof is that one willingly undergoes outward pain in order to avoid inward pain: and in so far as outward pain is not repugnant to the interior appetite, it becomes in a manner pleasant and agreeable by way of inward joy. Sometimes, however, outward pain is accompanied by inward pain, and then the pain is increased. Because inward pain is not only greater than outward pain, it is also more universal: since whatever is repugnant to the body, can be repugnant to the interior appetite; and whatever is apprehended by sense may be apprehended by imagination and reason, but not conversely. Hence in the passage quoted above it is said expressively: "Sadness of the heart is every wound," because even the pains of outward wounds are comprised in the interior sorrows of the heart.

[I-II.q.35.a.7.ad.1] Inward pain can also arise from things that are destructive of life. And then the comparison of inward to outward pain must not be taken in reference to the various evils that cause pain; but in regard to the various ways in which this cause of pain is compared to the appetite.

[I-II.q.35.a.7.ad.2] Inward pain is not caused by the apprehended likeness of a thing: for a man is not inwardly pained by the apprehended likeness itself, but by the thing which the likeness represents. And this thing is all the more perfectly apprehended by means of its likeness, as this likeness is more immaterial and abstract. Consequently inward pain is, of itself, greater, as being caused by a greater evil, forasmuch as evil is better known by an inward apprehension.

[I-II.q.35.a.7.ad.3] Bodily changes are more liable to be caused by outward pain, both from the fact that outward pain is caused by a corruptive conjoined corporally, which is a necessary condition of the sense of touch; and from the fact that the outward sense is more material than the inward sense, just as the sensitive appetite is more material than the intellective. For this reason, as stated above (22, 3; 31, 5), the body undergoes a greater change from the movement of the sensitive appetite: and, in like manner, from outward than from inward pain.

[I-II.q.35.a.8.arg.1] It would seem that Damascene's (De Fide Orth. ii, 14) division of sorrow into four species is incorrect; viz. into "torpor, distress," which Gregory of Nyssa [Nemesius, De Nat. Hom. xix.] calls "anxiety,"--"pity," and "envy." For sorrow is contrary to pleasure. But there are not several species of pleasure. Therefore it is incorrect to assign different species of sorrow.

[I-II.q.35.a.8.arg.2] Further, "Repentance" is a species of sorrow; and so are "indignation" and "jealousy," as the Philosopher states (Rhet. ii, 9,11). But these are not included in the above species. Therefore this division is insufficient.

[I-II.q.35.a.8.arg.3] Further, the members of a division should be things that are opposed to one another. But these species are not opposed to one another. For according to Gregory [Nemesius, De Nat. Hom. xix.] "torpor is sorrow depriving of speech; anxiety is the sorrow that weighs down; envy is sorrow for another's good; pity is sorrow for another's wrongs." But it is possible for one to sorrow for another's wrongs, and for another's good, and at the same time to be weighed down inwardly, and outwardly to be speechless. Therefore this division is correct.

[I-II.q.35.a.8.sc] stands the twofold authority of Gregory of Nyssa [Nemesius] and of Damascene.

[I-II.q.35.a.8.co] It belongs to the notion of a species that it is something added to the genus. But a thing can be added to a genus in two ways. First, as something belonging of itself to the genus, and virtually contained therein: thus "rational" is added to "animal." Such an addition makes true species of a genus: as the Philosopher says (Metaph. vii, 12; viii, 2,3). But, secondly, a thing may be added to a genus, that is, as it were, foreign to the notion conveyed by that genus: thus "white" or something of the kind may be added to "animal." Such an addition does not make true species of the genus, according to the usual sense in which we speak of genera and species. But sometimes a thing is said to be a species of a certain genus, through having something foreign to that genus indeed, but to which the notion of that genus is applicable: thus a live coal or a flame is said to be a species of fire, because in each of them the nature of fire is applied to a foreign matter. In like manner we speak of astronomy and perspective as being species of mathematics, inasmuch as the principles of mathematics are applied to natural matter.

In accordance with this manner of speaking, the species of sorrow are reckoned by an application of the notion of sorrow to something foreign to it. This foreign matter may be taken on the part of the cause or the object, or of the effect. For the proper object of sorrow is "one's own evil." Hence sorrow may be concerned for an object foreign to it either through one's being sorry for an evil that is not one's own; and thus we have "pity" which is sorrow for another's evil, considered, however, as one's own: or through one's being sorry for something that is neither evil nor one's own, but another's good, considered, however, as one's own evil: and thus we have "envy." The proper effect of sorrow consists in a certain "flight of the appetite." Wherefore the foreign element in the effect of sorrow, may be taken so as to affect the first part only, by excluding flight: and thus we have "anxiety" which weighs on the mind, so as to make escape seem impossible: hence it is also called "perplexity." If, however, the mind be weighed down so much, that even the limbs become motionless, which belongs to "torpor," then we have the foreign element affecting both, since there is neither flight, nor is the effect in the appetite. And the reason why torpor especially is said to deprive one of speech is because of all the external movements the voice is the best expression of the inward thought and desire, not only in men, but also in other animals, as is stated in Polit. i, 1.

[I-II.q.35.a.8.ad.1] Pleasure is caused by good, which has only one meaning: and so pleasure is not divided into several species as sorrow is; for the latter is caused by evil, which "happens in many ways," as Dionysius says (Div. Nom. iv).

[I-II.q.35.a.8.ad.2] Repentance is for one's own evil, which is the proper object of sorrow: wherefore it does not belong to these species. Jealousy and indignation are included in envy, as we shall explain later (II-II, 36, 2).

[I-II.q.35.a.8.ad.3] This division is not according to opposite species; but according to the diversity of foreign matter to which the notion of sorrow is applied, as stated above.
