FOURTH ARTICLE [I, Q. 60, Art. 4]

Whether an Angel Loves Another with Natural Love As He Loves Himself?

Objection 1: It would seem that an angel does not love another with

natural love as he loves himself. For love follows knowledge. But an

angel does not know another as he knows himself: because he knows

himself by his essence, while he knows another by his similitude, as

was said above (Q. 56, AA. 1, 2). Therefore it seems that one angel

does not love another with natural love as he loves himself.

Obj. 2: Further, the cause is more powerful than the effect; and the

principle than what is derived from it. But love for another comes of

love for self, as the Philosopher says (Ethic. ix, 8). Therefore one

angel does not love another as himself, but loves himself more.

Obj. 3: Further, natural love is of something as an end, and is

unremovable. But no angel is the end of another; and again, such love

can be severed from him, as is the case with the demons, who have no

love for the good angels. Therefore an angel does not love another

with natural love as he loves himself.

_On the contrary,_ That seems to be a natural property which is found

in all, even in such as devoid of reason. But, "every beast loves its

like," as is said, Ecclus. 13:19. Therefore an angel naturally loves

another as he loves himself.

_I answer that,_ As was observed (A. 3), both angel and man naturally

love self. Now what is one with a thing, is that thing itself:

consequently every thing loves what is one with itself. So, if this

be one with it by natural union, it loves it with natural love; but

if it be one with it by non-natural union, then it loves it with

non-natural love. Thus a man loves his fellow townsman with a social

love, while he loves a blood relation with natural affection, in so

far as he is one with him in the principle of natural generation.

Now it is evident that what is generically or specifically one with

another, is the one according to nature. And so everything loves

another which is one with it in species, with a natural affection, in

so far as it loves its own species. This is manifest even in things

devoid of knowledge: for fire has a natural inclination to communicate

its form to another thing, wherein consists this other thing's good;

as it is naturally inclined to seek its own good, namely, to be borne

upwards.

So then, it must be said that one angel loves another with natural

affection, in so far as he is one with him in nature. But so far as an

angel has something else in common with another angel, or differs from

him in other respects, he does not love him with natural love.

Reply Obj. 1: The expression 'as himself' can in one way qualify the

knowledge and the love on the part of the one known and loved: and

thus one angel knows another as himself, because he knows the other

to be even as he knows himself to be. In another way the expression

can qualify the knowledge and the love on the part of the knower and

lover. And thus one angel does not know another as himself, because

he knows himself by his essence, and the other not by the other's

essence. In like manner he does not love another as he loves himself,

because he loves himself by his own will; but he does not love

another by the other's will.

Reply Obj. 2: The expression "as" does not denote equality, but

likeness. For since natural affection rests upon natural unity, the

angel naturally loves less what is less one with him. Consequently he

loves more what is numerically one with himself, than what is one

only generically or specifically. But it is natural for him to have a

like love for another as for himself, in this respect, that as he

loves self in wishing well to self, so he loves another in wishing

well to him.

Reply Obj. 3: Natural love is said to be of the end, not as of that

end to which good is willed, but rather as of that good which one

wills for oneself, and in consequence for another, as united to

oneself. Nor can such natural love be stripped from the wicked

angels, without their still retaining a natural affection towards the

good angels, in so far as they share the same nature with them. But

they hate them, in so far as they are unlike them according to

righteousness and unrighteousness.
