[II-II.q.111.a.1.arg.1] It seems that not all dissimulation is a sin. For it is written (Luke 24:28) that our Lord "pretended [Douay: 'made as though'] he would go farther"; and Ambrose in his book on the Patriarchs (De Abraham i) says of Abraham that he "spoke craftily to his servants, when he said" (Genesis 22:5): "I and the boy will go with speed as far as yonder, and after we have worshipped, will return to you." Now to pretend and to speak craftily savor of dissimulation: and yet it is not to be said that there was sin in Christ or Abraham. Therefore not all dissimulation is a sin.

[II-II.q.111.a.1.arg.2] Further, no sin is profitable. But according to Jerome, in his commentary on Galatians 2:11, "When Peter [Vulgate: 'Cephas'] was come to Antioch:--The example of Jehu, king of Israel, who slew the priest of Baal, pretending that he desired to worship idols, should teach us that dissimulation is useful and sometimes to be employed"; and David "changed his countenance before" Achis, king of Geth (1 Samuel 21:13). Therefore not all dissimulation is a sin.

[II-II.q.111.a.1.arg.3] Further, good is contrary to evil. Therefore if it is evil to simulate good, it is good to simulate evil.

[II-II.q.111.a.1.arg.4] Further, it is written in condemnation of certain people (Isaiah 3:9): "They have proclaimed abroad their sin as Sodom, and they have not hid it." Now it pertains to dissimulation to hide one's sin. Therefore it is reprehensible sometimes not to simulate. But it is never reprehensible to avoid sin. Therefore dissimulation is not a sin.

[II-II.q.111.a.1.sc] A gloss on Isaiah 16:14, "In three years," etc., says: "Of the two evils it is less to sin openly than to simulate holiness." But to sin openly is always a sin. Therefore dissimulation is always a sin.

[II-II.q.111.a.1.co] As stated above (109, 3; 110, 1), it belongs to the virtue of truth to show oneself outwardly by outward signs to be such as one is. Now outward signs are not only words, but also deeds. Accordingly just as it is contrary to truth to signify by words something different from that which is in one's mind, so also is it contrary to truth to employ signs of deeds or things to signify the contrary of what is in oneself, and this is what is properly denoted by dissimulation. Consequently dissimulation is properly a lie told by the signs of outward deeds. Now it matters not whether one lie in word or in any other way, as stated above (110, 1, Objection 2). Wherefore, since every lie is a sin, as stated above (Question 110, Article 3), it follows that also all dissimulation is a sin.

[II-II.q.111.a.1.ad.1] As Augustine says (De QQ. Evang. ii), "To pretend is not always a lie: but only when the pretense has no signification, then it is a lie. When, however, our pretense refers to some signification, there is no lie, but a representation of the truth." And he cites figures of speech as an example, where a thing is "pretended," for we do not mean it to be taken literally but as a figure of something else that we wish to say. On this way our Lord "pretended He would go farther," because He acted as if wishing to go farther; in order to signify something figuratively either because He was far from their faith, according to Gregory (Hom. xxiii in Ev.); or, as Augustine says (De QQ. Evang. ii), because, "as He was about to go farther away from them by ascending into heaven, He was, so to speak, held back on earth by their hospitality."

Abraham also spoke figuratively. Wherefore Ambrose (De Abraham i) says that Abraham "foretold what he knew not": for he intended to return alone after sacrificing his son: but by his mouth the Lord expressed what He was about to do. It is evident therefore that neither dissembled.

[II-II.q.111.a.1.ad.2] Jerome employs the term "simulation" in a broad sense for any kind of pretense. David's change of countenance was a figurative pretense, as a gloss observes in commenting on the title of Psalm 33, "I will bless the Lord at all times." There is no need to excuse Jehu's dissimulation from sin or lie, because he was a wicked man, since he departed not from the idolatry of Jeroboam (2 Kings 10:29-31). And yet he is praised withal and received an earthly reward from God, not for his dissimulation, but for his zeal in destroying the worship of Baal.

[II-II.q.111.a.1.ad.3] Some say that no one may pretend to be wicked, because no one pretends to be wicked by doing good deeds, and if he do evil deeds, he is evil. But this argument proves nothing. Because a man might pretend to be evil, by doing what is not evil in itself but has some appearance of evil: and nevertheless this dissimulation is evil, both because it is a lie, and because it gives scandal; and although he is wicked on this account, yet his wickedness is not the wickedness he simulates. And because dissimulation is evil in itself, its sinfulness is not derived from the thing simulated, whether this be good or evil.

[II-II.q.111.a.1.ad.4] Just as a man lies when he signifies by word that which he is not, yet lies not when he refrains from saying what he is, for this is sometimes lawful; so also does a man dissemble, when by outward signs of deeds or things he signifies that which he is not, yet he dissembles not if he omits to signify what he is. Hence one may hide one's sin without being guilty of dissimulation. It is thus that we must understand the saying of Jerome on the words of Isaiah 3:9, that the "second remedy after shipwreck is to hide one's sin," lest, to wit, others be scandalized thereby.

[II-II.q.111.a.2.arg.1] It seems that hypocrisy is not the same as dissimulation. For dissimulation consists in lying by deeds. But there may be hypocrisy in showing outwardly what one does inwardly, according to Matthew 6:2, "When thou dost an alms-deed sound not a trumpet before thee, as the hypocrites do." Therefore hypocrisy is not the same as dissimulation.

[II-II.q.111.a.2.arg.2] Further, Gregory says (Moral. xxxi, 7): "Some there are who wear the habit of holiness, yet are unable to attain the merit of perfection. We must by no means deem these to have joined the ranks of the hypocrites, since it is one thing to sin from weakness, and another to sin from malice." Now those who wear the habit of holiness, without attaining the merit of perfection, are dissemblers, since the outward habit signifies works of perfection. Therefore dissimulation is not the same as hypocrisy.

[II-II.q.111.a.2.arg.3] Further, hypocrisy consists in the mere intention. For our Lord says of hypocrites (Matthew 23:5) that "all their works they do for to be seen of men": and Gregory says (Moral. xxxi, 7) that "they never consider what it is that they do, but how by their every action they may please men." But dissimulation consists, not in the mere intention, but in the outward action: wherefore a gloss on Job 36:13, "Dissemblers and crafty men prove the wrath of God," says that "the dissembler simulates one thing and does another: he pretends chastity, and delights in lewdness, he makes a show of poverty and fills his purse." Therefore hypocrisy is not the same as dissimulation.

[II-II.q.111.a.2.sc] Isidore says (Etym. x): "'Hypocrite' is a Greek word corresponding to the Latin 'simulator,' for whereas he is evil within," he "shows himself outwardly as being good; hypo denoting falsehood, and krisis, judgment."

[II-II.q.111.a.2.co] As Isidore says (Etym. x), "the word hypocrite is derived from the appearance of those who come on to the stage with a disguised face, by changing the color of their complexion, so as to imitate the complexion of the person they simulate, at one time under the guise of a man, at another under the guise of a woman, so as to deceive the people in their acting." Hence Augustine says (De Serm. Dom. ii) that "just as hypocrites by simulating other persons act the parts of those they are not (since he that acts the part of Agamemnon is not that man himself but pretends to be), so too in the Church and in every department of human life, whoever wishes to seem what he is not is a hypocrite: for he pretends to be just without being so in reality."

We must conclude, therefore, that hypocrisy is dissimulation, not, however, any form of dissimulation, but only when one person simulates another, as when a sinner simulates the person of a just man.

[II-II.q.111.a.2.ad.1] The outward deed is a natural sign of the intention. Accordingly when a man does good works pertaining by their genus to the service of God, and seeks by their means to please, not God but man, he simulates a right intention which he has not. Wherefore Gregory says (Moral.) that "hypocrites make God's interests subservient to worldly purposes, since by making a show of saintly conduct they seek, not to turn men to God, but to draw to themselves the applause of their approval:" and so they make a lying pretense of having a good intention, which they have not, although they do not pretend to do a good deed without doing it.

[II-II.q.111.a.2.ad.2] The habit of holiness, for instance the religious or the clerical habit, signifies a state whereby one is bound to perform works of perfection. And so when a man puts on the habit of holiness, with the intention of entering the state of perfection, if he fail through weakness, he is not a dissembler or a hypocrite, because he is not bound to disclose his sin by laying aside the habit of holiness. If, however, he were to put on the habit of holiness in order to make a show of righteousness, he would be a hypocrite and a dissembler.

[II-II.q.111.a.2.ad.3] In dissimulation, as in a lie, there are two things: one by way of sign, the other by way of thing signified. Accordingly the evil intention in hypocrisy is considered as a thing signified, which does not tally with the sign: and the outward words, or deeds, or any sensible objects are considered in every dissimulation and lie as a sign.

[II-II.q.111.a.3.arg.1] It seems that hypocrisy is not contrary to the virtue of truth. For in dissimulation or hypocrisy there is a sign and a thing signified. Now with regard to neither of these does it seem to be opposed to any special virtue: for a hypocrite simulates any virtue, and by means of any virtuous deeds, such as fasting, prayer and alms deeds, as stated in Matthew 6:1-18. Therefore hypocrisy is not specially opposed to the virtue of truth.

[II-II.q.111.a.3.arg.2] Further, all dissimulation seems to proceed from guile, wherefore it is opposed to simplicity. Now guile is opposed to prudence as above stated (55, 4). Therefore, hypocrisy which is dissimulation is not opposed to truth, but rather to prudence or simplicity.

[II-II.q.111.a.3.arg.3] Further, the species of moral acts is taken from their end. Now the end of hypocrisy is the acquisition of gain or vainglory: wherefore a gloss on Job 27:8, "What is the hope of the hypocrite, if through covetousness he take by violence," says: "A hypocrite or, as the Latin has it, a dissimulator, is a covetous thief: for through desire of being honored for holiness, though guilty of wickedness, he steals praise for a life which is not his." [The quotation is from St. Gregory's Moralia, Bk XVIII.] Therefore since covetousness or vainglory is not directly opposed to truth, it seems that neither is hypocrisy or dissimulation.

[II-II.q.111.a.3.sc] All dissimulation is a lie, as stated above (Article 1). Now a lie is directly opposed to truth. Therefore dissimulation or hypocrisy is also.

[II-II.q.111.a.3.co] According to the Philosopher (Metaph. text. 13, 24, x), "contrariety is opposition as regards form," i.e. the specific form. Accordingly we must reply that dissimulation or hypocrisy may be opposed to a virtue in two ways, in one way directly, in another way indirectly. Its direct opposition or contrariety is to be considered with regard to the very species of the act, and this species depends on that act's proper object. Wherefore since hypocrisy is a kind of dissimulation, whereby a man simulates a character which is not his, as stated in the preceding article, it follows that it is directly opposed to truth whereby a man shows himself in life and speech to be what he is, as stated in Ethic. iv, 7.

The indirect opposition or contrariety of hypocrisy may be considered in relation to any accident, for instance a remote end, or an instrument of action, or anything else of that kind.

[II-II.q.111.a.3.ad.1] The hypocrite in simulating a virtue regards it as his end, not in respect of its existence, as though he wished to have it, but in respect of appearance, since he wishes to seem to have it. Hence his hypocrisy is not opposed to that virtue, but to truth, inasmuch as he wishes to deceive men with regard to that virtue. And he performs acts of that virtue, not as intending them for their own sake, but instrumentally, as signs of that virtue, wherefore his hypocrisy has not, on that account, a direct opposition to that virtue.

[II-II.q.111.a.3.ad.2] As stated above (55, 3,4,5), the vice directly opposed to prudence is cunning, to which it belongs to discover ways of achieving a purpose, that are apparent and not real: while it accomplishes that purpose, by guile in words, and by fraud in deeds: and it stands in relation to prudence, as guile and fraud to simplicity. Now guile and fraud are directed chiefly to deception, and sometimes secondarily to injury. Wherefore it belongs directly to simplicity to guard oneself from deception, and in this way the virtue of simplicity is the same as the virtue of truth as stated above (109, 2, ad 4). There is, however, a mere logical difference between them, because by truth we mean the concordance between sign and thing signified, while simplicity indicates that one does not tend to different things, by intending one thing inwardly, and pretending another outwardly.

[II-II.q.111.a.3.ad.3] Gain or glory is the remote end of the dissembler as also of the liar. Hence it does not take its species from this end, but from the proximate end, which is to show oneself other than one is. Wherefore it sometimes happens to a man to pretend great things of himself, for no further purpose than the mere lust of hypocrisy, as the Philosopher says (Ethic. iv, 7), and as also we have said above with regard to lying (110, 2).
