We must now consider the vices opposed to magnanimity; and in the first place, those that are opposed thereto by excess. These are three, namely, presumption, ambition, and vainglory. Secondly, we shall consider pusillanimity which is opposed to it by way of deficiency. Under the first head there are two points of inquiry:
(1) Whether presumption is a sin?
(2) Whether it is opposed to magnanimity by excess?
Objection 1: It would seem that presumption, which is a sin against the Holy Ghost, trusts, not in God, but in our own power. For the lesser the power, the more grievously does he sin who trusts in it too much. But man's power is less than God's. Therefore it is a more grievous sin to presume on human power than to presume on the power of God. Now the sin against the Holy Ghost is most grievous. Therefore presumption, which is reckoned a species of sin against the Holy Ghost, trusts to human rather than to Divine power.
Objection 1: It seems that presumption is not a sin. For the Apostle says: "Forgetting the things that are behind, I stretch forth [Vulg.: 'and stretching forth'] myself to those that are before." But it seems to savor of presumption that one should tend to what is above oneself. Therefore presumption is not a sin.
Objection 2: Further, other sins arise from the sin against the Holy Ghost, for this sin is called malice which is a source from which sins arise. Now other sins seem to arise from the presumption whereby man presumes on himself rather than from the presumption whereby he presumes on God, since self-love is the origin of sin, according to Augustine (De Civ. Dei xiv, 28). Therefore it seems that presumption which is a sin against the Holy Ghost, relies chiefly on human power.
Objection 2: Further, the Philosopher says (Ethic. i, 7) "we should not listen to those who would persuade us to relish human things because we are men, or mortal things because we are mortal, but we should relish those that make us immortal": and (Metaph. i) "that man should pursue divine things as far as possible." Now divine and immortal things are seemingly far above man. Since then presumption consists essentially in tending to what is above oneself, it seems that presumption is something praiseworthy, rather than a sin.
Objection 3: Further, sin arises from the inordinate conversion to a mutable good. Now presumption is a sin. Therefore it arises from turning to human power, which is a mutable good, rather than from turning to the power of God, which is an immutable good.
Objection 3: Further, the Apostle says (2 Cor. 3:5): "Not that we are sufficient to think anything of ourselves, as of ourselves." If then presumption, by which one strives at that for which one is not sufficient, be a sin, it seems that man cannot lawfully even think of anything good: which is absurd. Therefore presumption is not a sin.
On the contrary, Just as, through despair, a man despises the Divine mercy, on which hope relies, so, through presumption, he despises the Divine justice, which punishes the sinner. Now justice is in God even as mercy is. Therefore, just as despair consists in aversion from God, so presumption consists in inordinate conversion to Him.
On the contrary, It is written (Ecclus. 37:3): "O wicked presumption, whence camest thou?" and a gloss answers: "From a creature's evil will." Now all that comes of the root of an evil will is a sin. Therefore presumption is a sin.
I answer that, Presumption seems to imply immoderate hope. Now the object of hope is an arduous possible good: and a thing is possible to a man in two ways: first by his own power; secondly, by the power of God alone. With regard to either hope there may be presumption owing to lack of moderation. As to the hope whereby a man relies on his own power, there is presumption if he tends to a good as though it were possible to him, whereas it surpasses his powers, according to Judith 6:15: "Thou humblest them that presume of themselves." This presumption is contrary to the virtue of magnanimity which holds to the mean in this kind of hope. But as to the hope whereby a man relies on the power of God, there may be presumption through immoderation, in the fact that a man tends to some good as though it were possible by the power and mercy of God, whereas it is not possible, for instance, if a man hope to obtain pardon without repenting, or glory without merits. This presumption is, properly, the sin against the Holy Ghost, because, to wit, by presuming thus a man removes or despises the assistance of the Holy Spirit, whereby he is withdrawn from sin.
I answer that, Since whatever is according to nature, is ordered by the Divine Reason, which human reason ought to imitate, whatever is done in accordance with human reason in opposition to the order established in general throughout natural things is vicious and sinful. Now it is established throughout all natural things, that every action is commensurate with the power of the agent, nor does any natural agent strive to do what exceeds its ability. Hence it is vicious and sinful, as being contrary to the natural order, that any one should assume to do what is above his power: and this is what is meant by presumption, as its very name shows. Wherefore it is evident that presumption is a sin.
Reply to Objection 1: As stated above (Question [20], Article [3]; FS, Question [73], Article [3]) a sin which is against God is, in its genus, graver than other sins. Hence presumption whereby a man relies on God inordinately, is a more grievous sin than the presumption of trusting in one's own power, since to rely on the Divine power for obtaining what is unbecoming to God, is to depreciate the Divine power, and it is evident that it is a graver sin to detract from the Divine power than to exaggerate one's own.
Reply to Objection 1: Nothing hinders that which is above the active power of a natural thing, and yet not above the passive power of that same thing: thus the air is possessed of a passive power by reason of which it can be so changed as to obtain the action and movement of fire, which surpass the active power of air. Thus too it would be sinful and presumptuous for a man while in a state of imperfect virtue to attempt the immediate accomplishment of what belongs to perfect virtue. But it is not presumptuous or sinful for a man to endeavor to advance towards perfect virtue. In this way the Apostle stretched himself forth to the things that were before him, namely continually advancing forward.
Reply to Objection 2: The presumption whereby a man presumes inordinately on God, includes self-love, whereby he loves his own good inordinately. For when we desire a thing very much, we think we can easily procure it through others, even though we cannot.
Reply to Objection 2: Divine and immortal things surpass man according to the order of nature. Yet man is possessed of a natural power, namely the intellect, whereby he can be united to immortal and Divine things. In this respect the Philosopher says that "man ought to pursue immortal and divine things," not that he should do what it becomes God to do, but that he should be united to Him in intellect and will.
Reply to Objection 3: Presumption on God's mercy implies both conversion to a mutable good, in so far as it arises from an inordinate desire of one's own good, and aversion from the immutable good, in as much as it ascribes to the Divine power that which is unbecoming to it, for thus man turns away from God's power.
Reply to Objection 3: As the Philosopher says (Ethic. iii, 3), "what we can do by the help of others we can do by ourselves in a sense." Hence since we can think and do good by the help of God, this is not altogether above our ability. Hence it is not presumptuous for a man to attempt the accomplishment of a virtuous deed: but it would be presumptuous if one were to make the attempt without confidence in God's assistance.
Objection 1: It would seem that presumption is not a sin. For no sin is a reason why man should be heard by God. Yet, through presumption some are heard by God, for it is written (Judith 9:17): "Hear me a poor wretch making supplication to Thee, and presuming of Thy mercy." Therefore presumption on God's mercy is not a sin.
Objection 1: It seems that presumption is not opposed to magnanimity by excess. For presumption is accounted a species of the sin against the Holy Ghost, as stated above (Question [14], Article [2]; Question [21], Article [1]). But the sin against the Holy Ghost is not opposed to magnanimity, but to charity. Neither therefore is presumption opposed to magnanimity.
Objection 2: Further, presumption denotes excessive hope. But there cannot be excess of that hope which is in God, since His power and mercy are infinite. Therefore it seems that presumption is not a sin.
Objection 2: Further, it belongs to magnanimity that one should deem oneself worthy of great things. But a man is said to be presumptuous even if he deem himself worthy of small things, if they surpass his ability. Therefore presumption is not directly opposed to magnanimity.
Objection 3: Further, that which is a sin does not excuse from sin: for the Master says (Sent. ii, D, 22) that "Adam sinned less, because he sinned in the hope of pardon," which seems to indicate presumption. Therefore presumption is not a sin.
Objection 3: Further, the magnanimous man looks upon external goods as little things. Now according to the Philosopher (Ethic. iv, 3), "on account of external fortune the presumptuous disdain and wrong others, because they deem external goods as something great." Therefore presumption is opposed to magnanimity, not by excess, but only by deficiency.
On the contrary, It is reckoned a species of sin against the Holy Ghost.
On the contrary, The Philosopher says (Ethic. ii, 7; iv, 3) that the "vain man," i.e. a vaporer or a wind-bag, which with us denotes a presumptuous man, "is opposed to the magnanimous man by excess."
I answer that, As stated above (Question [20], Article [1]) with regard to despair, every appetitive movement that is conformed to a false intellect, is evil in itself and sinful. Now presumption is an appetitive movement, since it denotes an inordinate hope. Moreover it is conformed to a false intellect, just as despair is: for just as it is false that God does not pardon the repentant, or that He does not turn sinners to repentance, so is it false that He grants forgiveness to those who persevere in their sins, and that He gives glory to those who cease from good works: and it is to this estimate that the movement of presumption is conformed. Consequently presumption is a sin, but less grave than despair, since, on account of His infinite goodness, it is more proper to God to have mercy and to spare, than to punish: for the former becomes God in Himself, the latter becomes Him by reason of our sins.
I answer that, As stated above (Question [129], Article [3], ad 1), magnanimity observes the means, not as regards the quantity of that to which it tends, but in proportion to our own ability: for it does not tend to anything greater than is becoming to us.
Now the presumptuous man, as regards that to which he tends, does not exceed the magnanimous, but sometimes falls far short of him: but he does exceed in proportion to his own ability, whereas the magnanimous man does not exceed his. It is in this way that presumption is opposed to magnanimity by excess.
Reply to Objection 1: Presumption sometimes stands for hope, because even the right hope which we have in God seems to be presumption, if it be measured according to man's estate: yet it is not, if we look at the immensity of the goodness of God.
Reply to Objection 1: It is not every presumption that is accounted a sin against the Holy Ghost, but that by which one contemns the Divine justice through inordinate confidence in the Divine mercy. The latter kind of presumption, by reason of its matter, inasmuch, to wit, as it implies contempt of something Divine, is opposed to charity, or rather to the gift of fear, whereby we revere God. Nevertheless, in so far as this contempt exceeds the proportion to one's own ability, it can be opposed to magnanimity.
Reply to Objection 2: Presumption does not denote excessive hope, as though man hoped too much in God; but through man hoping to obtain from God something unbecoming to Him; which is the same as to hope too little in Him, since it implies a depreciation of His power; as stated above (Article [1], ad 1).
Reply to Objection 2: Presumption, like magnanimity, seems to tend to something great. For we are not, as a rule, wont to call a man presumptuous for going beyond his powers in something small. If, however, such a man be called presumptuous, this kind of presumption is not opposed to magnanimity, but to that virtue which is about ordinary honor, as stated above (Question [129], Article [2]).
Reply to Objection 3: To sin with the intention of persevering in sin and through the hope of being pardoned, is presumptuous, and this does not diminish, but increases sin. To sin, however, with the hope of obtaining pardon some time, and with the intention of refraining from sin and of repenting of it, is not presumptuous, but diminishes sin, because this seems to indicate a will less hardened in sin.
Reply to Objection 3: No one attempts what is above his ability, except in so far as he deems his ability greater than it is. In this one may err in two ways. First only as regards quantity, as when a man thinks he has greater virtue, or knowledge, or the like, than he has. Secondly, as regards the kind of thing, as when he thinks himself great, and worthy of great things, by reason of something that does not make him so, for instance by reason of riches or goods of fortune. For, as the Philosopher says (Ethic. iv, 3), "those who have these things without virtue, neither justly deem themselves worthy of great things, nor are rightly called magnanimous."
Again, the thing to which a man sometimes tends in excess of his ability, is sometimes in very truth something great, simply as in the case of Peter, whose intent was to suffer for Christ, which has exceeded his power; while sometimes it is something great, not simply, but only in the opinion of fools, such as wearing costly clothes, despising and wronging others. This savors of an excess of magnanimity, not in any truth, but in people's opinion. Hence Seneca says (De Quat. Virtut.) that "when magnanimity exceeds its measure, it makes a man high-handed, proud, haughty restless, and bent on excelling in all things, whether in words or in deeds, without any considerations of virtue." Thus it is evident that the presumptuous man sometimes falls short of the magnanimous in reality, although in appearance he surpasses him.
