SUMMA THEOLOGICA. Thomas Aquinas
the object of the intellect is the true, while the object of the will is the good. Now the good and the true differ, not really but only logically [*Cf. Question [16], Article [4]]. Therefore will and intellect are not really different.
Objection 3: Further, the distinction of common and proper does not differentiate the faculties; for the same power of sight perceives color and whiteness. But the good and the true seem to be mutually related as common to particular; for the true is a particular good, to wit, of the intellect. Therefore the will, whose object is the good, does not differ from the intellect, whose object is the true.
On the contrary, The will in the angels regards good things only, while their intellect regards both good and bad things, for they know both. Therefore the will of the angels is distinct from their intellect.
I answer that, In the angels the will is a special faculty or power, which is neither their nature nor their intellect. That it is not their nature is manifest from this, that the nature or essence of a thing is completely comprised within it: whatever, then, extends to anything beyond it, is not its essence. Hence we see in natural bodies that the inclination to being does not come from anything superadded to the essence, but from the matter which desires being before possessing it, and from the form which keeps it in such being when once it exists. But the inclination towards something extrinsic comes from something superadded to the essence; as tendency to a place comes from gravity or lightness, while the inclination to make something like itself comes from the active qualities.
Now the will has a natural tendency towards good. Consequently there alone are essence and will identified where all good is contained within the essence of him who wills; that is to say, in God, Who wills nothing beyond Himself except on account of His goodness. This cannot be said of any creature, because infinite goodness is quite foreign to the nature of any created thing. Accordingly, neither the will of the angel, nor that of any creature, can be the same thing as its essence.
In like manner neither can the will be the same thing as the intellect of angel or man. Because knowledge comes about in so far as the object known is within the knower; consequently the intellect extends itself to what is outside it, according as what, in its essence, is outside it is disposed to be somehow within it. On the other hand, the will goes out to what is beyond it, according as by a kind of inclination it tends, in a manner, to what is outside it. Now it belongs to one faculty to have within itself something which is outside it, and to another faculty to tend to what is outside it. Consequently intellect and will must necessarily be different powers in every creature. It is not so with God, for He has within Himself universal being, and the universal good. Therefore both intellect and will are His nature.
Reply to Objection 1: A natural body is moved to its own being by its substantial form: while it is inclined to something outside by something additional, as has been said.
Reply to Objection 2: Faculties are not differentiated by any material difference of their objects, but according to their formal distinction, which is taken from the nature of the object as such. Consequently the diversity derived from the notion of good and true suffices for the difference of intellect from will.
Reply to Objection 3: Because the good and the true are really convertible, it follows that the good is apprehended by the intellect as something true; while the true is desired by the will as something good. Nevertheless, the diversity of their aspects is sufficient for diversifying the faculties, as was said above (ad 2).
Whether there is free-will in the angels?
Objection 1: It would seem that there is no free-will in the angels. For the act of free-will is to choose. But there can be no choice with the angels, because choice is "the desire of something after taking counsel," while counsel is "a kind of inquiry," as stated in Ethic. iii, 3. But the angels' knowledge is not the result of inquiring, for this belongs to the discursiveness of reason. Therefore it appears that there is no free-will in the angels.
Objection 2: Further, free-will implies indifference to alternatives. But in the angels on the part of their intellect there is no such indifference; because, as was observed already ( Question [58], Article [5]), their intellect is not deceived as to things which are naturally intelligible to them. Therefore neither on the part of their appetitive faculty can there be free-will.
Objection 3: Further, the natural endowments of the angels belong to them according to degrees of more or less; because in the higher angels the intellectual nature is more perfect than in the lower. But the free-will does not admit of degrees. Therefore there is no free-will in them.
On the contrary, Free-will is part of man's dignity. But the angels' dignity surpasses that of men. Therefore, since free-will is in men, with much more reason is it in the angels.
I answer that, Some things there are which act, not from any previous judgment, but, as it were, moved and made to act by others; just as the arrow is directed to the target by the archer. Others act from some kind of judgment; but not from free-will, such as irrational animals; for the sheep flies from the wolf by a kind of judgment whereby it esteems it to be hurtful to itself: such a judgment is not a free one, but implanted by nature. Only an agent endowed with an intellect can act with a judgment which is free, in so far as it apprehends the common note of goodness; from which it can judge this or the other thing to be good. Consequently, wherever there is intellect, there is free-will. It is therefore manifest that just as there is intellect, so is there free-will in the angels, and in a higher degree of perfection than in man.
Reply to Objection 1: The Philosopher is speaking of choice, as it is in man. As a man's estimate in speculative matters differs from an angel's in this, that the one needs not to inquire, while the other does so need; so is it in practical matters. Hence there is choice in the angels, yet not with the inquisitive deliberation of counsel, but by the sudden acceptance of truth.
Reply to Objection 2: As was observed already ( Article [2]), knowledge is effected by the presence of the known within the knower. Now it is a mark of imperfection in anything not to have within it what it should naturally have. Consequently an angel would not be perfect in his nature, if his intellect were not determined to every truth which he can know naturally. But the act of the appetitive faculty comes of this, that the affection is directed to something outside. Yet the perfection of a thing does not come from everything to which it is inclined, but only from something which is higher than it. Therefore it does not argue imperfection in an angel if his will be not determined with regard to things beneath him; but it would argue imperfection in him, with he to be indeterminate to what is above him.
Reply to Objection 3: Free-will exists in a nobler manner in the higher angels than it does in the lower, as also does the judgment of the intellect. Yet it is true that liberty, in so far as the removal of compulsion is considered, is not susceptible of greater and less degree; because privations and negations are not lessened nor increased directly of themselves; but only by their cause, or through the addition of some qualification.
Whether there is an irascible and a concupiscible appetite in the angels?
Objection 1: It would seem that there is an irascible and a concupiscible appetite in the angels. For Dionysius says (Div. Nom. iv) that in the demons there is "unreasonable fury and wild concupiscence." But demons are of the same nature as angels; for sin has not altered their nature. Therefore there is an irascible and a concupiscible appetite in the angels.
Objection 2: Further, love and joy are in the concupiscible; while anger, hope, and fear are in the irascible appetite. But in the Sacred Scriptures these things are attributed both to the good and to the wicked angels. Therefore there is an irascible and a concupiscible appetite in the angels.
Objection 3: Further, some virtues are said to
