Summa Theologica Part III (Secunda Secundae) Part 23

Since then the sin against the Holy Ghost is the most grievous sin, it seems that man comes to commit this sin through committing lesser sins.

Obj. 2: Further, to sin against the Holy Ghost is to sin through certain malice, or through choice. Now man cannot do this until he has sinned many times; for the Philosopher says (Ethic. v, 6, 9) that "although a man is able to do unjust deeds, yet he cannot all at once do them as an unjust man does," viz. from choice. Therefore it seems that the sin against the Holy Ghost cannot be committed except after other sins.

Obj. 3: Further, repentance and impenitence are about the same object. But there is no repentance, except about past sins. Therefore the same applies to impenitence which is a species of the sin against the Holy Ghost. Therefore the sin against the Holy Ghost presupposes other sins.

_On the contrary,_ "It is easy in the eyes of G.o.d on a sudden to make a poor man rich" (Ecclus. 11:23). Therefore, conversely, it is possible for a man, according to the malice of the devil who tempts him, to be led to commit the most grievous of sins which is that against the Holy Ghost.

_I answer that,_ As stated above (A. 1), in one way, to sin against the Holy Ghost is to sin through certain malice. Now one may sin through certain malice in two ways, as stated in the same place: first, through the inclination of a habit; but this is not, properly speaking, to sin against the Holy Ghost, nor does a man come to commit this sin all at once, in as much as sinful acts must precede so as to cause the habit that induces to sin. Secondly, one may sin through certain malice, by contemptuously rejecting the things whereby a man is withdrawn from sin. This is, properly speaking, to sin against the Holy Ghost, as stated above (A. 1); and this also, for the most part, presupposes other sins, for it is written (Prov.

18:3) that "the wicked man, when he is come into the depth of sins, contemneth."

Nevertheless it is possible for a man, in his first sinful act, to sin against the Holy Ghost by contempt, both on account of his free-will, and on account of the many previous dispositions, or again, through being vehemently moved to evil, while but feebly attached to good. Hence never or scarcely ever does it happen that the perfect sin all at once against the Holy Ghost: wherefore Origen says (Peri Archon. i, 3): "I do not think that anyone who stands on the highest step of perfection, can fail or fall suddenly; this can only happen by degrees and bit by bit."

The same applies, if the sin against the Holy Ghost be taken literally for blasphemy against the Holy Ghost. For such blasphemy as Our Lord speaks of, always proceeds from contemptuous malice.

If, however, with Augustine (De Verb. Dom., Serm. lxxi) we understand the sin against the Holy Ghost to denote final impenitence, it does not regard the question in point, because this sin against the Holy Ghost requires persistence in sin until the end of life.

Reply Obj. 1: Movement both in good and in evil is made, for the most part, from imperfect to perfect, according as man progresses in good or evil: and yet in both cases, one man can begin from a greater (good or evil) than another man does. Consequently, that from which a man begins can be perfect in good or evil according to its genus, although it may be imperfect as regards the series of good or evil actions whereby a man progresses in good or evil.

Reply Obj. 2: This argument considers the sin which is committed through certain malice, when it proceeds from the inclination of a habit.

Reply Obj. 3: If by impenitence we understand with Augustine (De Verb. Dom., Serm. lxxi) persistence in sin until the end, it is clear that it presupposes sin, just as repentance does. If, however, we take it for habitual impenitence, in which sense it is a sin against the Holy Ghost, it is evident that it can precede sin: for it is possible for a man who has never sinned to have the purpose either of repenting or of not repenting, if he should happen to sin.

QUESTION 15

OF THE VICES OPPOSED TO KNOWLEDGE AND UNDERSTANDING (In Three Articles)

We must now consider the vices opposed to knowledge and understanding. Since, however, we have treated of ignorance which is opposed to knowledge, when we were discussing the causes of sins (I-II, Q. 76), we must now inquire about blindness of mind and dulness of sense, which are opposed to the gift of understanding; and under this head there are three points of inquiry:

(1) Whether blindness of mind is a sin?

(2) Whether dulness of sense is a sin distinct from blindness of mind?

(3) Whether these vices arise from sins of the flesh?

_______________________

FIRST ARTICLE [II-II, Q. 15, Art. 1]

Whether Blindness of Mind Is a Sin?

Objection 1: It would seem that blindness of mind is not a sin.

Because, seemingly, that which excuses from sin is not itself a sin.

Now blindness of mind excuses from sin; for it is written (John 9:41): "If you were blind, you should not have sin." Therefore blindness of mind is not a sin.

Obj. 2: Further, punishment differs from guilt. But blindness of mind is a punishment as appears from Isa. 6:10, "Blind the heart of this people," for, since it is an evil, it could not be from G.o.d, were it not a punishment. Therefore blindness of mind is not a sin.

Obj. 3: Further, every sin is voluntary, according to Augustine (De Vera Relig. xiv). Now blindness of mind is not voluntary, since, as Augustine says (Confess. x), "all love to know the resplendent truth," and as we read in Eccles. 11:7, "the light is sweet and it is delightful for the eyes to see the sun." Therefore blindness of mind is not a sin.

_On the contrary,_ Gregory (Moral. x.x.xi, 45) reckons blindness of mind among the vices arising from l.u.s.t.

_I answer that,_ Just as bodily blindness is the privation of the principle of bodily sight, so blindness of mind is the privation of the principle of mental or intellectual sight. Now this has a threefold principle. One is the light of natural reason, which light, since it pertains to the species of the rational soul, is never forfeit from the soul, and yet, at times, it is prevented from exercising its proper act, through being hindered by the lower powers which the human intellect needs in order to understand, for instance in the case of imbeciles and madmen, as stated in the First Part (Q.

84, AA. 7, 8).

Another principle of intellectual sight is a certain habitual light superadded to the natural light of reason, which light is sometimes forfeit from the soul. This privation is blindness, and is a punishment, in so far as the privation of the light of grace is a punishment. Hence it is written concerning some (Wis. 2:21): "Their own malice blinded them."

A third principle of intellectual sight is an intelligible principle, through which a man understands other things; to which principle a man may attend or not attend. That he does not attend thereto happens in two ways. Sometimes it is due to the fact that a man's will is deliberately turned away from the consideration of that principle, according to Ps. 35:4, "He would not understand, that he might do well": whereas sometimes it is due to the mind being more busy about things which it loves more, so as to be hindered thereby from considering this principle, according to Ps. 57:9, "Fire," i.e. of concupiscence, "hath fallen on them and they shall not see the sun."

In either of these ways blindness of mind is a sin.

Reply Obj. 1: The blindness that excuses from sin is that which arises from the natural defect of one who cannot see.

Reply Obj. 2: This argument considers the second kind of blindness which is a punishment.

Reply Obj. 3: To understand the truth is, in itself, beloved by all; and yet, accidentally it may be hateful to someone, in so far as a man is hindered thereby from having what he loves yet more.

SECOND ARTICLE [II-II, Q. 15, Art. 2]

Whether Dulness of Sense Is a Sin Distinct from Blindness of Mind?

Objection 1: It seems that dulness of sense is not a distinct sin from blindness of mind. Because one thing has one contrary. Now dulness is opposed to the gift of understanding, according to Gregory (Moral. ii, 49); and so is blindness of mind, since understanding denotes a principle of sight. Therefore dulness of sense is the same as blindness of mind.

Obj. 2: Further, Gregory (Moral. x.x.xi, 45) in speaking of dulness describes it as "dulness of sense in respect of understanding." Now dulness of sense in respect of understanding seems to be the same as a defect in understanding, which pertains to blindness of mind.

Therefore dulness of sense is the same as blindness of mind.

Obj. 3: Further, if they differ at all, it seems to be chiefly in the fact that blindness of mind is voluntary, as stated above (A. 1), while dulness of sense is a natural defect. But a natural defect is not a sin: so that, accordingly, dulness of sense would not be a sin, which is contrary to what Gregory says (Moral. x.x.xi, 45), where he reckons it among the sins arising from gluttony.

_On the contrary,_ Different causes produce different effects. Now Gregory says (Moral. x.x.xi, 45) that dulness of sense arises from gluttony, and that blindness of mind arises from l.u.s.t. Now these others are different vices. Therefore those are different vices also.

_I answer that,_ Dull is opposed to sharp: and a thing is said to be sharp because it can pierce; so that a thing is called dull through being obtuse and unable to pierce. Now a bodily sense, by a kind of metaphor, is said to pierce the medium, in so far as it perceives its object from a distance or is able by penetration as it were to perceive the smallest details or the inmost parts of a thing. Hence in corporeal things the senses are said to be acute when they can perceive a sensible object from afar, by sight, hearing, or scent, while on the other hand they are said to be dull, through being unable to perceive, except sensible objects that are near at hand, or of great power.

Now, by way of similitude to bodily sense, we speak of sense in connection with the intellect; and this latter sense is in respect of certain primals and extremes, as stated in _Ethic._ vi, even as the senses are cognizant of sensible objects as of certain principles of knowledge. Now this sense which is connected with understanding, does not perceive its object through a medium of corporeal distance, but through certain other media, as, for instance, when it perceives a thing's essence through a property thereof, and the cause through its effect. Consequently a man is said to have an acute sense in connection with his understanding, if, as soon as he apprehends a property or effect of a thing, he understands the nature or the thing itself, and if he can succeed in perceiving its slightest details: whereas a man is said to have a dull sense in connection with his understanding, if he cannot arrive at knowing the truth about a thing, without many explanations; in which case, moreover, he is unable to obtain a perfect perception of everything pertaining to the nature of that thing.

Accordingly dulness of sense in connection with understanding denotes a certain weakness of the mind as to the consideration of spiritual goods; while blindness of mind implies the complete privation of the knowledge of such things. Both are opposed to the gift of understanding, whereby a man knows spiritual goods by apprehending them, and has a subtle penetration of their inmost nature. This dulness has the character of sin, just as blindness of mind has, that is, in so far as it is voluntary, as evidenced in one who, owing to his affection for carnal things, dislikes or neglects the careful consideration of spiritual things.

This suffices for the Replies to the Objections.

THIRD ARTICLE [II-II, Q. 15, Art. 3]

Whether Blindness of Mind and Dulness of Sense Arise from Sins of the Flesh?

Objection 1: It would seem that blindness of mind and dulness of sense do not arise from sins of the flesh. For Augustine (Retract. i, 4) retracts what he had said in his Soliloquies i, 1, "G.o.d Who didst wish none but the clean to know the truth," and says that one might reply that "many, even those who are unclean, know many truths." Now men become unclean chiefly by sins of the flesh. Therefore blindness of mind and dulness of sense are not caused by sins of the flesh.

Obj. 2: Further, blindness of mind and dulness of sense are defects in connection with the intellective part of the soul: whereas carnal sins pertain to the corruption of the flesh. But the flesh does not act on the soul, but rather the reverse. Therefore the sins of the flesh do not cause blindness of mind and dulness of sense.

Obj. 3: Further, all things are more pa.s.sive to what is near them than to what is remote. Now spiritual vices are nearer the mind than carnal vices are. Therefore blindness of mind and dulness of sense are caused by spiritual rather than by carnal vices.

_On the contrary,_ Gregory says (Moral. x.x.xi, 45) that dulness of sense arises from gluttony and blindness of mind from l.u.s.t.
