1 Objection 1: It would seem that corporeal matter obeys the mere will of an angel. For the power of an angel excels the power of the soul. But corporeal matter obeys a conception of the soul; for the body of man is changed by a conception of the soul as regards heat and cold, and sometimes even as regards health and sickness. Therefore much more is corporeal matter changed by a conception of an angel.
1 Ad secundum sic proceditur. Videtur quod materia corporalis obediat Angelis ad nutum. Maior est enim virtus Angeli quam virtus animae. Sed conceptioni animae obedit materia corporalis, immutatur enim corpus hominis ex conceptione animae, ad calorem et frigus, et quandoque usque ad sanitatem et aegritudinem. Ergo multo magis secundum conceptionem Angeli, materia corporalis transmutatur.
2 Objection 2: Further, whatever can be done by an inferior power, can be done by a superior power. Now the power of an angel is superior to corporeal power. But a body by its power is able to transform corporeal matter; as appears when fire begets fire. Therefore much more efficaciously can an angel by his power transform corporeal matter.
2 Praeterea, quidquid potest virtus inferior, potest virtus superior. Sed virtus Angeli est superior quam virtus corporalis. Corpus autem sua virtute potest transmutare materiam corporalem ad formam aliquam; sicut cum ignis generat ignem. Ergo multo fortius virtute sua Angeli possunt materiam corporalem transmutare ad aliquam formam.
3 Objection 3: Further, all corporeal nature is under angelic administration, as appears above Article 1), and thus it appears that bodies are as instruments to the angels, for an instrument is essentially a mover moved. Now in effects there is something that is due to the power of their principal agents, and which cannot be due to the power of the instrument; and this it is that takes the principal place in the effect. For example, digestion is due to the force of natural heat, which is the instrument of the nutritive soul: but that living flesh is thus generated is due to the power of the soul. Again the cutting of the wood is from the saw; but that it assumes the length the form of a bed is from the design of the joiner's) art. Therefore the substantial form which takes the principal place in the corporeal effects, is due to the angelic power. Therefore matter obeys the angels in receiving its form.
3 Praeterea, tota natura corporalis administratur per Angelos, ut dictum est, et sic videtur quod corpora se habet ad Angelos sicut instrumenta; nam ratio instrumenti est quod sit movens motum. Sed in effectibus aliquid invenitur ex virtute principalium agentium, quod non potest esse per virtutem instrumenti; et hoc est id quod est principalius in effectu. Sicut digestio nutrimenti est per virtutem caloris naturalis, qui est instrumentum animae nutritivae; sed quod generetur caro viva, est ex virtute animae. Similiter quod secetur lignum, pertinet ad serram; sed quod perveniatur ad formam lecti, est ex ratione artis. Ergo forma substantialis, quae est principalius in effectibus corporalibus, est ex virtute Angelorum. Materia ergo obedit, ad sui informationem, Angelis.
4 On the contrary, Augustine says It is not to be thought, that this visible matter obeys these rebel angels; for it obeys God alone.
4 Sed contra est quod Augustinus dicit, III de Trin., non est putandum istis transgressoribus Angelis ad nutum servire hanc visibilium rerum materiam, sed soli Deo.
5 I answer that, The Platonists asserted that the forms which are in matter are caused by immaterial forms, because they said that the material forms are participations of immaterial forms. Avicenna followed them in this opinion to some extent, for he said that all forms which are in matter proceed from the concept of the intellect; and that corporeal agents only dispose matter) for the forms. They seem to have been deceived on this point, through supposing a form to be something made per se, so that it would be the effect of a formal principle.
But, as the Philosopher proves Metaph. vii, Did. vi, 8), what is made, properly speaking, is the composite: for this properly speaking, is, as it were, what subsists. Whereas the form is called a being, not as that which is, but as that by which something is; and consequently neither is a form, properly speaking, made; for that is made which is; since to be is nothing but the way to existence. Now it is manifest that what is made is like to the maker, forasmuch as every agent makes its like.
So whatever makes natural things, has a likeness to the composite; either because it is composite itself, as when fire begets fire, or because the whole composite as to both matter and form is within its power; and this belongs to God alone. Therefore every informing of matter is either immediately from God, or form some corporeal agent; but not immediately from an angel.
5 Respondeo dicendum quod Platonici posuerunt formas quae sunt in materia, causari ex immaterialibus formis, quia formas materiales ponebant esse participationes quasdam immaterialium formarum. Et hos, quantum ad aliquid, secutus est Avicenna, qui posuit omnes formas quae sunt in materia, procedere a conceptione intelligentiae, et quod agentia corporalia sunt solum disponentia ad formas. Qui in hoc videntur fuisse decepti, quia existimaverunt formam quasi aliquid per se factum, ut sic ab aliquo formali principio procederet. Sed sicut philosophus probat in VII Metaphys., hoc quod proprie fit, est compositum, hoc enim proprie est quasi subsistens. Forma autem non dicitur ens quasi ipsa sit, sed sicut quo aliquid est, et sic per consequens nec forma proprie fit; eius enim est fieri, cuius est esse, cum fieri nihil aliud sit quam via in esse. Manifestum est autem quod factum est simile facienti, quia omne agens agit sibi simile. Et ideo id quod facit res naturales, habet similitudinem cum composito, vel quia est compositum, sicut ignis generat ignem; vel quia totum compositum, et quantum ad materiam et quantum ad formam, est in virtute ipsius; quod est proprium Dei. Sic igitur omnis informatio materiae vel est a Deo immediate, vel ab aliquo agente corporali; non autem immediate ab Angelo.
6 Reply to Objection 1: Our soul is united to the body as the form; and so it is not surprising for the body to be formally changed by the soul's concept; especially as the movement of the sensitive appetite, which is accompanied with a certain bodily change, is subject to the command of reason. An angel, however, has not the same connection with natural bodies; and hence the argument does not hold.
6 Ad primum ergo dicendum quod anima nostra unitur corpori ut forma; et sic non est mirum, si formaliter transmutatur ex conceptione ipsius; praesertim cum motus sensitivi appetitus, qui fit cum quadam transmutatione corporali, subdatur imperio rationis. Angelus autem non sic se habet ad corpora naturalia. Unde ratio non sequitur.
7 Reply to Objection 2: Whatever an inferior power can do, that a superior power can do, not in the same way, but in a more excellent way; for example, the intellect knows sensible things in a more excellent way than sense knows them. So an angel can change corporeal matter in a more excellent way than can corporeal agents, that is by moving the corporeal agents themselves, as being the superior cause.
7 Ad secundum dicendum quod id quod potest virtus inferior, potest superior non eodem, sed excellentiori modo, sicut intellectus cognoscit sensibilia excellentiori modo quam sensus. Et sic Angelus excellentiori modo transmutat materiam corporalem quam agentia corporalia, scilicet movendo ipsa agentia corporalia, tanquam causa superior.
8 Reply to Objection 3: There is nothing to prevent some natural effect taking place by angelic power, for which the power of corporeal agents would not suffice. This, however, is not to obey an angel's will as neither does matter obey the mere will of a cook, when by regulating the fire according to the prescription of his art he produces a dish that the fire could not have produced by itself); since to reduce matter to the act of the substantial form does not exceed the power of a corporeal agent; for it is natural for like to make like.
8 Ad tertium dicendum quod nihil prohibet ex virtute Angelorum aliquos effectus sequi in rebus naturalibus, ad quae agentia corporalia non sufficerent. Sed hoc non est obedire materiam Angelis ad nutum; sicut nec coquis obedit materia ad nutum, quia aliquem modum decoctionis operantur per ignem secundum aliquam artis moderationem, quam ignis per se non faceret, cum reducere materiam in actum formae substantialis, non excedat virtutem corporalis agentis, quia simile natum est sibi simile facere.
