SECOND ARTICLE [I, Q. 5, Art. 2]

Whether Goodness Is Prior in Idea to Being?

Objection 1: It seems that goodness is prior in idea to being. For

names are arranged according to the arrangement of the things

signified by the names. But Dionysius (Div. Nom. iii) assigned the

first place, amongst the other names of God, to His goodness rather

than to His being. Therefore in idea goodness is prior to being.

Obj. 2: Further, that which is the more extensive is prior in

idea. But goodness is more extensive than being, because, as Dionysius

notes (Div. Nom. v), "goodness extends to things both existing and

non-existing; whereas existence extends to existing things alone."

Therefore goodness is in idea prior to being.

Obj. 3: Further, what is the more universal is prior in idea. But

goodness seems to be more universal than being, since goodness has the

aspect of desirable; whereas to some non-existence is desirable; for

it is said of Judas: "It were better for him, if that man had not been

born" (Matt. 26:24). Therefore in idea goodness is prior to being.

Obj. 4: Further, not only is existence desirable, but life,

knowledge, and many other things besides. Thus it seems that existence

is a particular appetible, and goodness a universal appetible.

Therefore, absolutely, goodness is prior in idea to being.

_On the contrary,_ It is said by Aristotle (De Causis) that "the first

of created things is being."

_I answer that,_ In idea being is prior to goodness. For the meaning

signified by the name of a thing is that which the mind conceives of

the thing and intends by the word that stands for it. Therefore, that

is prior in idea, which is first conceived by the intellect. Now the

first thing conceived by the intellect is being; because everything is

knowable only inasmuch as it is in actuality. Hence, being is the

proper object of the intellect, and is primarily intelligible; as

sound is that which is primarily audible. Therefore in idea being is

prior to goodness.

Reply Obj. 1: Dionysius discusses the Divine Names (Div. Nom.

i, iii) as implying some causal relation in God; for we name God, as

he says, from creatures, as a cause from its effects. But goodness,

since it has the aspect of desirable, implies the idea of a final

cause, the causality of which is first among causes, since an agent

does not act except for some end; and by an agent matter is moved to

its form. Hence the end is called the cause of causes. Thus goodness,

as a cause, is prior to being, as is the end to the form. Therefore

among the names signifying the divine causality, goodness precedes

being. Again, according to the Platonists, who, through not

distinguishing primary matter from privation, said that matter was

non-being, goodness is more extensively participated than being; for

primary matter participates in goodness as tending to it, for all seek

their like; but it does not participate in being, since it is presumed

to be non-being. Therefore Dionysius says that "goodness extends to

non-existence" (Div. Nom. v).

Reply Obj. 2: The same solution is applied to this objection.

Or it may be said that goodness extends to existing and non-existing

things, not so far as it can be predicated of them, but so far as it

can cause them--if, indeed, by non-existence we understand not simply

those things which do not exist, but those which are potential, and

not actual. For goodness has the aspect of the end, in which not only

actual things find their completion, but also towards which tend even

those things which are not actual, but merely potential. Now being

implies the habitude of a formal cause only, either inherent or

exemplar; and its causality does not extend save to those things which

are actual.

Reply Obj. 3: Non-being is desirable, not of itself, but only

relatively--i.e. inasmuch as the removal of an evil, which can only

be removed by non-being, is desirable. Now the removal of an evil

cannot be desirable, except so far as this evil deprives a thing of

some being. Therefore being is desirable of itself; and non-being only

relatively, inasmuch as one seeks some mode of being of which one

cannot bear to be deprived; thus even non-being can be spoken of as

relatively good.

Reply Obj. 4: Life, wisdom, and the like, are desirable only

so far as they are actual. Hence, in each one of them some sort of

being is desired. And thus nothing can be desired except being; and

consequently nothing is good except being.
