Back to part 1
Part I, Question 3, Article 6: Whether in God there are any accidents?
Objection 1: It seems that there are accidents in God. For substance cannot be an accident, as Aristotle says (Phys. i). Therefore that which is an accident in one, cannot, in another, be a substance. Thus it is proved that heat cannot be the substantial form of fire, because it is an accident in other things. But wisdom, virtue, and the like, which are accidents in us, are attributes of God. Therefore in God there are accidents.
Objection 2: Further, in every genus there is a first principle. But there are many "genera" of accidents. If, therefore, the primal members of these genera are not in God, there will be many primal beings other than God -- which is absurd.
On the contrary: Every accident is in a subject. But God cannot be a subject, for "no simple form can be a subject", as Boethius says (De Trin.). Therefore in God there cannot be any accident.
I answer that: From all we have said, it is clear there can be no accident in God. First, because a subject is compared to its accidents as potentiality to actuality; for a subject is in some sense made actual by its accidents. But there can be no potentiality in God, as was shown (Question , Article ). Secondly, because God is His own existence; and as Boethius says (Hebdom.), although every essence may have something superadded to it, this cannot apply to absolute being: thus a heated substance can have something extraneous to heat added to it, as whiteness, nevertheless absolute heat can have nothing else than heat. Thirdly, because what is essential is prior to what is accidental. Whence as God is absolute primal being, there can be in Him nothing accidental. Neither can He have any essential accidents (as the capability of laughing is an essential accident of man), because such accidents are caused by the constituent principles of the subject. Now there can be nothing caused in God, since He is the first cause. Hence it follows that there is no accident in God.
Reply to Objection 1: Virtue and wisdom are not predicated of God and of us univocally. Hence it does not follow that there are accidents in God as there are in us.
Reply to Objection 2: Since substance is prior to its accidents, the principles of accidents are reducible to the principles of the substance as to that which is prior; although God is not first as if contained in the genus of substance; yet He is first in respect to all being, outside of every genus.
Part I, Question 3, Article 7: Whether God is altogether simple?
Objection 1: It seems that God is not altogether simple. For whatever is from God must imitate Him. Thus from the first being are all beings; and from the first good is all good. But in the things which God has made, nothing is altogether simple. Therefore neither is God altogether simple.
Objection 2: Further, whatever is best must be attributed to God. But with us that which is composite is better than that which is simple; thus, chemical compounds are better than simple elements, and animals than the parts that compose them. Therefore it cannot be said that God is altogether simple.
On the contrary: Augustine says (De Trin. iv, 6,7): "God is truly and absolutely simple."
I answer that: The absolute simplicity of God may be shown in many ways. First, from the previous articles of this question. For there is neither composition of quantitative parts in God, since He is not a body; nor composition of matter and form; nor does His nature differ from His "suppositum"; nor His essence from His existence; neither is there in Him composition of genus and difference, nor of subject and accident. Therefore, it is clear that God is nowise composite, but is altogether simple. Secondly, because every composite is posterior to its component parts, and is dependent on them; but God is the first being, as shown above (Question , Article ). Thirdly, because every composite has a cause, for things in themselves different cannot unite unless something causes them to unite. But God is uncaused, as shown above (Question , Article ), since He is the first efficient cause. Fourthly, because in every composite there must be potentiality and actuality; but this does not apply to God; for either one of the parts actuates another, or at least all the parts are potential to the whole. Fifthly, because nothing composite can be predicated of any single one of its parts. And this is evident in a whole made up of dissimilar parts; for no part of a man is a man, nor any of the parts of the foot, a foot. But in wholes made up of similar parts, although something which is predicated of the whole may be predicated of a part (as a part of the air is air, and a part of water, water), nevertheless certain things are predicable of the whole which cannot be predicated of any of the parts; for instance, if the whole volume of water is two cubits, no part of it can be two cubits. Thus in every composite there is something which is not it itself. But, even if this could be said of whatever has a form, viz. that it has something which is not it itself, as in a white object there is something which does not belong to the essence of white; nevertheless in the form itself, there is nothing besides itself. And so, since God is absolute form, or rather absolute being, He can be in no way composite. Hilary implies this argument, when he says (De Trin. vii): "God, Who is strength, is not made up of things that are weak; nor is He Who is light, composed of things that are dim."
Reply to Objection 1: Whatever is from God imitates Him, as caused things imitate the first cause. But it is of the essence of a thing to be in some sort composite; because at least its existence differs from its essence, as will be shown hereafter, (Question , Article ).
Reply to Objection 2: With us composite things are better than simple things, because the perfections of created goodness cannot be found in one simple thing, but in many things. But the perfection of divine goodness is found in one simple thing (Question , Article  and Question , Article ).
Part I, Question 4, Article 2: Whether the perfections of all things are in God?
Objection 1: It seems that the perfections of all things are not in God. For God is simple, as shown above (Question , Article ); whereas the perfections of things are many and diverse. Therefore the perfections of all things are not in God.
Objection 2: Further, opposites cannot coexist. Now the perfections of things are opposed to each other, for each thing is perfected by its specific difference. But the differences by which "genera" are divided, and "species" constituted, are opposed to each other. Therefore because opposites cannot coexist in the same subject, it seems that the perfections of all things are not in God.
Objection 3: Further, a living thing is more perfect than what merely exists; and an intelligent thing than what merely lives. Therefore life is more perfect than existence; and knowledge than life. But the essence of God is existence itself. Therefore He has not the perfections of life, and knowledge, and other similar perfections.
On the contrary: Dionysius says (Div. Nom. v) that "God in His one existence prepossesses all things."
I answer that: All created perfections are in God. Hence He is spoken of as universally perfect, because He lacks not (says the Commentator, Metaph. v) any excellence which may be found in any genus. This may be seen from two considerations. First, because whatever perfection exists in an effect must be found in the effective cause: either in the same formality, if it is a univocal agent -- as when man reproduces man; or in a more eminent degree, if it is an equivocal agent -- thus in the sun is the likeness of whatever is generated by the sun's power. Now it is plain that the effect pre-exists virtually in the efficient cause: and although to pre-exist in the potentiality of a material cause is to pre-exist in a more imperfect way, since matter as such is imperfect, and an agent as such is perfect; still to pre-exist virtually in the efficient cause is to pre-exist not in a more imperfect, but in a more perfect way. Since therefore God is the first effective cause of things, the perfections of all things must pre-exist in God in a more eminent way. Dionysius implies the same line of argument by saying of God (Div. Nom. v): "It is not that He is this and not that, but that He is all, as the cause of all." Secondly, from what has been already proved, God is existence itself, of itself subsistent (Question , Article ). Consequently, He must contain within Himself the whole perfection of being. For it is clear that if some hot thing has not the whole perfection of heat, this is because heat is not participated in its full perfection; but if this heat were self-subsisting, nothing of the virtue of heat would be wanting to it. Since therefore God is subsisting being itself, nothing of the perfection of being can be wanting to Him. Now all created perfections are included in the perfection of being; for things are perfect, precisely so far as they have being after some fashion. It follows therefore that the perfection of no one thing is wanting to God. This line of argument, too, is implied by Dionysius (Div. Nom. v), when he says that, "God exists not in any single mode, but embraces all being within Himself, absolutely, without limitation, uniformly;" and afterwards he adds that, "He is the very existence to subsisting things."
Reply to Objection 1: Even as the sun (as Dionysius remarks, (Div. Nom. v)), while remaining one and shining uniformly, contains within itself first and uniformly the substances of sensible things, and many and diverse qualities; "a fortiori" should all things in a kind of natural unity pre-exist in the cause of all things; and thus things diverse and in themselves opposed to each other, pre-exist in God as one, without injury to His simplicity. This suffices for the Reply to the Second Objection.
Reply to Objection 3: The same Dionysius says (Div. Nom. v) that, although existence is more perfect than life, and life than wisdom, if they are considered as distinguished in idea; nevertheless, a living thing is more perfect than what merely exists, because living things also exist and intelligent things both exist and live. Although therefore existence does not include life and wisdom, because that which participates in existence need not participate in every mode of existence; nevertheless God's existence includes in itself life and wisdom, because nothing of the perfection of being can be wanting to Him who is subsisting being itself.
Part I, Question 5, Article 1: Whether goodness differs really from being? Objection 1: It seems that goodness differs really from being. For Boethius says (De Hebdom.): "I perceive that in nature the fact that things are good is one thing: that they are is another." Therefore goodness and being really differ.
Objection 2: Further, nothing can be its own form. "But that is called good which has the form of being", according to the commentary on De Causis. Therefore goodness differs really from being.
Objection 3: Further, goodness can be more or less. But being cannot be more or less. Therefore goodness differs really from being.
On the contrary: Augustine says (De Doctr. Christ. i, 42) that, "inasmuch as we exist we are good."
I answer that: Goodness and being are really the same, and differ only in idea; which is clear from the following argument. The essence of goodness consists in this, that it is in some way desirable. Hence the Philosopher says (Ethic. i): "Goodness is what all desire." Now it is clear that a thing is desirable only in so far as it is perfect; for all desire their own perfection. But everything is perfect so far as it is actual. Therefore it is clear that a thing is perfect so far as it exists; for it is existence that makes all things actual, as is clear from the foregoing (Question , Article ; Question , Article ). Hence it is clear that goodness and being are the same really. But goodness presents the aspect of desirableness, which being does not present.
Reply to Objection 1: Although goodness and being are the same really, nevertheless since they differ in thought, they are not predicated of a thing absolutely in the same way. Since being properly signifies that something actually is, and actuality properly correlates to potentiality; a thing is, in consequence, said simply to have being, accordingly as it is primarily distinguished from that which is only in potentiality; and this is precisely each thing's substantial being. Hence by its substantial being, everything is said to have being simply; but by any further actuality it is said to have being relatively. Thus to be white implies relative being, for to be white does not take a thing out of simply potential being; because only a thing that actually has being can receive this mode of being. But goodness signifies perfection which is desirable; and consequently of ultimate perfection. Hence that which has ultimate perfection is said to be simply good; but that which has not the ultimate perfection it ought to have (although, in so far as it is at all actual, it has some perfection), is not said to be perfect simply nor good simply, but only relatively. In this way, therefore, viewed in its primal (i.e. substantial) being a thing is said to be simply, and to be good relatively (i.e. in so far as it has being) but viewed in its complete actuality, a thing is said to be relatively, and to be good simply. Hence the saying of Boethius (De Hebrom.), "I perceive that in nature the fact that things are good is one thing; that they are is another," is to be referred to a thing's goodness simply, and having being simply. Because, regarded in its primal actuality, a thing simply exists; and regarded in its complete actuality, it is good simply -- in such sort that even in its primal actuality, it is in some sort good, and even in its complete actuality, it in some sort has being.
Reply to Objection 2: Goodness is a form so far as absolute goodness signifies complete actuality.
Reply to Objection 3: Again, goodness is spoken of as more or less according to a thing's superadded actuality, for example, as to knowledge or virtue.
Part I, Question 5, Article 3: Whether every being is good?
Objection 1: It seems that not every being is good. For goodness is something superadded to being, as is clear from Article . But whatever is added to being limits it; as substance, quantity, quality, etc. Therefore goodness limits being. Therefore not every being is good.
Objection 2: Further, no evil is good: "Woe to you that call evil good and good evil" (Is. 5:20). But some things are called evil. Therefore not every being is good.
Objection 3: Further, goodness implies desirability. Now primary matter does not imply desirability, but rather that which desires. Therefore primary matter does not contain the formality of goodness. Therefore not every being is good.
Objection 4: Further, the Philosopher notes (Metaph. iii) that "in mathematics goodness does not exist." But mathematics are entities; otherwise there would be no science of mathematics. Therefore not every being is good.
On the contrary: Every being that is not God is God's creature. Now every creature of God is good (1 Tim. 4:4): and God is the greatest good. Therefore every being is good.
I answer that: Every being, as being, is good. For all being, as being, has actuality and is in some way perfect; since every act implies some sort of perfection; and perfection implies desirability and goodness, as is clear from Article . Hence it follows that every being as such is good.
Reply to Objection 1: Substance, quantity, quality, and everything included in them, limit being by applying it to some essence or nature. Now in this sense, goodness does not add anything to being beyond the aspect of desirability and perfection, which is also proper to being, whatever kind of nature it may be. Hence goodness does not limit being.
Reply to Objection 2: No being can be spoken of as evil, formally as being, but only so far as it lacks being. Thus a man is said to be evil, because he lacks some virtue; and an eye is said to be evil, because it lacks the power to see well.
Reply to Objection 3: As primary matter has only potential being, so it is only potentially good. Although, according to the Platonists, primary matter may be said to be a non-being on account of the privation attaching to it, nevertheless, it does participate to a certain extent in goodness, viz. by its relation to, or aptitude for, goodness. Consequently, to be desirable is not its property, but to desire.
Reply to Objection 4: Mathematical entities do not subsist as realities; because they would be in some sort good if they subsisted; but they have only logical existence, inasmuch as they are abstracted from motion and matter; thus they cannot have the aspect of an end, which itself has the aspect of moving another. Nor is it repugnant that there should be in some logical entity neither goodness nor form of goodness; since the idea of being is prior to the idea of goodness, as was said in the preceding article.
Part I, Question 5, Article 5: Whether the essence of goodness consists in mode, species and order?
Objection 1: It seems that the essence of goodness does not consist in mode, species and order. For goodness and being differ logically. But mode, species and order seem to belong to the nature of being, for it is written: "Thou hast ordered all things in measure, and number, and weight" (Wis. 11:21). And to these three can be reduced species, mode and order, as Augustine says (Gen. ad lit. iv, 3): "Measure fixes the mode of everything, number gives it its species, and weight gives it rest and stability." Therefore the essence of goodness does not consist in mode, species and order.
Objection 2: Further, mode, species and order are themselves good. Therefore if the essence of goodness consists in mode, species and order, then every mode must have its own mode, species and order. The same would be the case with species and order in endless succession.
Objection 3: Further, evil is the privation of mode, species and order. But evil is not the total absence of goodness. Therefore the essence of goodness does not consist in mode, species and order.
Objection 4: Further, that wherein consists the essence of goodness cannot be spoken of as evil. Yet we can speak of an evil mode, species and order. Therefore the essence of goodness does not consist in mode, species and order.
Objection 5: Further, mode, species and order are caused by weight, number and measure, as appears from the quotation from Augustine. But not every good thing has weight, number and measure; for Ambrose says (Hexam. i, 9): "It is of the nature of light not to have been created in number, weight and measure." Therefore the essence of goodness does not consist in mode, species and order.
On the contrary: Augustine says (De Nat. Boni. iii): "These three -- mode, species and order -- as common good things, are in everything God has made; thus, where these three abound the things are very good; where they are less, the things are less good; where they do not exist at all, there can be nothing good." But this would not be unless the essence of goodness consisted in them. Therefore the essence of goodness consists in mode, species and order.
I answer that: Everything is said to be good so far as it is perfect; for in that way only is it desirable (as shown above Articles ,3). Now a thing is said to be perfect if it lacks nothing according to the mode of its perfection. But since everything is what it is by its form (and since the form presupposes certain things, and from the form certain things necessarily follow), in order for a thing to be perfect and good it must have a form, together with all that precedes and follows upon that form. Now the form presupposes determination or commensuration of its principles, whether material or efficient, and this is signified by the mode: hence it is said that the measure marks the mode. But the form itself is signified by the species; for everything is placed in its species by its form. Hence the number is said to give the species, for definitions signifying species are like numbers, according to the Philosopher (Metaph. x); for as a unit added to, or taken from a number, changes its species, so a difference added to, or taken from a definition, changes its species. Further, upon the form follows an inclination to the end, or to an action, or something of the sort; for everything, in so far as it is in act, acts and tends towards that which is in accordance with its form; and this belongs to weight and order. Hence the essence of goodness, so far as it consists in perfection, consists also in mode, species and order.
Reply to Objection 1: These three only follow upon being, so far as it is perfect, and according to this perfection is it good.
Reply to Objection 2: Mode, species and order are said to be good, and to be beings, not as though they themselves were subsistences, but because it is through them that other things are both beings and good. Hence they have no need of other things whereby they are good: for they are spoken of as good, not as though formally constituted so by something else, but as formally constituting others good: thus whiteness is not said to be a being as though it were by anything else; but because, by it, something else has accidental being, as an object that is white.
Reply to Objection 3: Every being is due to some form. Hence, according to every being of a thing is its mode, species, order. Thus, a man has a mode, species and order as he is white, virtuous, learned and so on; according to everything predicated of him. But evil deprives a thing of some sort of being, as blindness deprives us of that being which is sight; yet it does not destroy every mode, species and order, but only such as follow upon the being of sight.
Reply to Objection 4: Augustine says (De Nat. Boni. xxiii), "Every mode, as mode, is good" (and the same can be said of species and order). "But an evil mode, species and order are so called as being less than they ought to be, or as not belonging to that which they ought to belong. Therefore they are called evil, because they are out of place and incongruous."
Reply to Objection 5: The nature of light is spoken of as being without number, weight and measure, not absolutely, but in comparison with corporeal things, because the power of light extends to all corporeal things; inasmuch as it is an active quality of the first body that causes change, i.e. the heavens.
Part I, Question 6, Article 1: Whether God is good?
Objection 1: It seems that to be good does not belong to God. For goodness consists in mode, species and order. But these do not seem to belong to God; since God is immense and is not ordered to anything else. Therefore to be good does not belong to God.
Objection 2: Further, the good is what all things desire. But all things do not desire God, because all things do not know Him; and nothing is desired unless it is known. Therefore to be good does not belong to God.
On the contrary: It is written (Lam. 3:25): "The Lord is good to them that hope in Him, to the soul that seeketh Him."
I answer that: To be good belongs pre-eminently to God. For a thing is good according to its desirableness. Now everything seeks after its own perfection; and the perfection and form of an effect consist in a certain likeness to the agent, since every agent makes its like; and hence the agent itself is desirable and has the nature of good. For the very thing which is desirable in it is the participation of its likeness. Therefore, since God is the first effective cause of all things, it is manifest that the aspect of good and of desirableness belong to Him; and hence Dionysius (Div. Nom. iv) attributes good to God as to the first efficient cause, saying that, God is called good "as by Whom all things subsist."
Reply to Objection 1: To have mode, species and order belongs to the essence of caused good; but good is in God as in its cause, and hence it belongs to Him to impose mode, species and order on others; wherefore these three things are in God as in their cause.
Reply to Objection 2: All things, by desiring their own perfection, desire God Himself, inasmuch as the perfections of all things are so many similitudes of the divine being; as appears from what is said above (Question , Article ). And so of those things which desire God, some know Him as He is Himself, and this is proper to the rational creature; others know some participation of His goodness, and this belongs also to sensible knowledge; others have a natural desire without knowledge, as being directed to their ends by a higher intelligence.
