SUMMA THEOLOGICA. Thomas Aquinas
have in their own nature.
Now they know this through a twofold medium, namely, by innate ideas, or by the forms of things existing in the Word. For by beholding the Word, they know not merely the being of things as existing in the Word, but the being as possessed by the things themselves; as God by contemplating Himself sees that being which things have in their own nature. It, therefore, it be called evening knowledge, in so far as when the angels behold the Word, they know the being which things have in their proper nature, then the morning and the evening knowledge are essentially one and the same, and only differ as to the things known. If it be called evening knowledge, in so far as through innate ideas they know the being which things have in their own natures, then the morning and the evening knowledge differ. Thus Augustine seems to understand it when he assigns one as inferior to the other.
Reply to Objection 1: The six days, as Augustine understands them, are taken as the six classes of things known by the angels; so that the day's unit is taken according to the unit of the thing understood; which, nevertheless, can be apprehended by various ways of knowing it.
Reply to Objection 2: There can be two operations of the same faculty at the one time, one of which is referred to the other; as is evident when the will at the same time wills the end and the means to the end; and the intellect at the same instant perceives principles and conclusions through those principles, when it has already acquired knowledge. As Augustine says (Gen. ad lit. iv, 24), the evening knowledge is referred to the morning knowledge in the angels; hence there is nothing to hinder both from being at the same time in the angels.
Reply to Objection 3: On the coming of what is perfect, the opposite imperfect is done away: just as faith, which is of the things that are not seen, is made void when vision succeeds. But the imperfection of the evening knowledge is not opposed to the perfection of the morning knowledge. For that a thing be known in itself, is not opposite to its being known in its cause. Nor, again, is there any inconsistency in knowing a thing through two mediums, one of which is more perfect and the other less perfect; just as we can have a demonstrative and a probable medium for reaching the same conclusion. In like manner a thing can be known by the angel through the uncreated Word, and through an innate idea.
THE WILL OF THE ANGELS (FOUR ARTICLES)
In the next place we must treat of things concerning the will of the angels. In the first place we shall treat of the will itself; secondly, of its movement, which is love. Under the first heading there are four points of inquiry:
(1) Whether there is will in the angels?
(2) Whether the will of the angel is his nature, or his intellect?
(3) Is there free-will in the angels?
(4) Is there an irascible and a concupiscible appetite in them?
Whether there is will in the angels?
Objection 1: It would seem that there is no will in the angels. For as the Philosopher says (De Anima iii, text. 42), "The will is in the reason." But there is no reason in the angels, but something higher than reason. Therefore there is no will in the angels, but something higher than the will.
Objection 2: Further, the will is comprised under the appetite, as is evident from the Philosopher (De Anima iii, text. 42). But the appetite argues something imperfect; because it is a desire of something not as yet possessed. Therefore, since there is no imperfection in the angels, especially in the blessed ones, it seems that there is no will in them.
Objection 3: Further, the Philosopher says (De Anima ii, text. 54) that the will is a mover which is moved; for it is moved by the appetible object understood. Now the angels are immovable, since they are incorporeal. Therefore there is no will in the angels.
On the contrary, Augustine says (De Trin. x, 11,12) that the image of the Trinity is found in the soul according to memory, understanding, and will. But God's image is found not only in the soul of man, but also in the angelic mind, since it also is capable of knowing God. Therefore there is will in the angels.
I answer that, We must necessarily place a will in the angels. In evidence thereof, it must be borne in mind that, since all things flow from the Divine will, all things in their own way are inclined by appetite towards good, but in different ways. Some are inclined to good by their natural inclination, without knowledge, as plants and inanimate bodies. Such inclination towards good is called "a natural appetite." Others, again, are inclined towards good, but with some knowledge; not that they know the aspect of goodness, but that they apprehend some particular good; as in the sense, which knows the sweet, the white, and so on. The inclination which follows this apprehension is called "a sensitive appetite." Other things, again, have an inclination towards good, but with a knowledge whereby they perceive the aspect of goodness; this belongs to the intellect. This is most perfectly inclined towards what is good; not, indeed, as if it were merely guided by another towards some particular good only, like things devoid of knowledge, nor towards some particular good only, as things which have only sensitive knowledge, but as inclined towards good in general. Such inclination is termed "will." Accordingly, since the angels by their intellect know the universal aspect of goodness, it is manifest that there is a will in them.
Reply to Objection 1: Reason surpasses sense in a different way from that in which intellect surpasses reason. Reason surpasses sense according to the diversity of the objects known; for sense judges of particular objects, while reason judges of universals. Therefore there must be one appetite tending towards good in the abstract, which appetite belongs to reason; and another with a tendency towards particular good, which appetite belongs to sense. But intellect and reason differ as to their manner of knowing; because the intellect knows by simple intuition, while reason knows by a process of discursion from one thing to another. Nevertheless by such discursion reason comes to know what intellect learns without it, namely, the universal. Consequently the object presented to the appetitive faculty on the part of reason and on the part of intellect is the same. Therefore in the angels, who are purely intellectual, there is no appetite higher than the will.
Reply to Objection 2: Although the name of the appetitive part is derived from seeking things not yet possessed, yet the appetitive part reaches out not to these things only, but also to many other things; thus the name of a stone [lapis] is derived from injuring the foot [laesione pedis], though not this alone belongs to a stone. In the same way the irascible faculty is so denominated from anger [ira]; though at the same time there are several other passions in it, as hope, daring, and the rest.
Reply to Objection 3: The will is called a mover which is moved, according as to will and to understand are termed movements of a kind; and there is nothing to prevent movement of this kind from existing in the angels, since such movement is the act of a perfect agent, as stated in De Anima iii, text. 28.
Whether in the angels the will differs from the intellect?
Objection 1: It would seem that in the angel the will does not differ from the intellect and from the nature. For an angel is more simple than a natural body. But a natural body is inclined through its form towards its end, which is its good. Therefore much more so is the angel. Now the angel's form is either the nature in which he subsists, or else it is some species within his intellect. Therefore the angel inclines towards the good through his own nature, or through an intelligible species. But such inclination towards the good belongs to the will. Therefore the will of the angel does not differ from his nature or his intellect.
Objection 2: Further,
