1 Objection 1: It would seem that the forms of bodies come from the angels. For Boethius says De Trin. i): From forms that are without matter come the forms that are in matter. But forms that are without matter are spiritual substances, and forms that are in matter are the forms of bodies. Therefore, the forms of bodies are from spiritual substances.
1 Ad quartum sic proceditur. Videtur quod formae corporum sint ab Angelis. Dicit enim Boetius, in libro de Trin., quod a formis quae sunt sine materia, veniunt formae quae sunt in materia. Formae autem quae sunt sine materia, sunt substantiae spirituales, formae autem quae sunt in materia, sunt formae corporum. Ergo formae corporum sunt a spiritualibus substantiis.
2 Objection 2: Further, all that is such by participation is reduced to that which is such by its essence. But spiritual substances are forms essentially, whereas corporeal creatures have forms by participation. Therefore the forms of corporeal things are derived from spiritual substances.
2 Praeterea, omne quod est per participationem, reducitur ad id quod est per essentiam. Sed spirituales substantiae per suam essentiam sunt formae, creaturae autem corporales participant formas. Ergo formae corporalium rerum sunt a spiritualibus substantiis derivatae.
3 Objection 3: Further, spiritual substances have more power of causation than the heavenly bodies. But the heavenly bodies give form to things here below, for which reason they are said to cause generation and corruption. Much more, therefore, are material forms derived from spiritual substances.
3 Praeterea, spirituales substantiae magis habent virtutem causandi quam corpora caelestia. Sed corpora caelestia causant formas in istis inferioribus, unde dicuntur esse generationis et corruptionis causa. Ergo multo magis a spiritualibus substantiis formae quae sunt in materia, derivantur.
4 On the contrary, Augustine says De Trin. iii, 8): We must not suppose that this corporeal matter serves the angels at their nod, but rather that it obeys God thus. But corporeal matter may be said thus to serve that from which it receives its form. Corporeal forms, then, are not from the angels, but from God.
4 Sed contra est quod Augustinus dicit, III de Trin., quod non est putandum Angelis ad nutum servire hanc corporalem materiam, sed potius Deo. Illi autem ad nutum dicitur servire corporalis materia, a quo speciem recipit. Non ergo formae corporales sunt ab Angelis, sed a Deo.
5 I answer that, It was the opinion of some that all corporeal forms are derived from spiritual substances, which we call the angels. And there are two ways in which this has been stated. For Plato held that the forms of corporeal matter are derived from, and formed by, forms immaterially subsisting, by a kind of participation. Thus he held that there exists an immaterial man, and an immaterial horse, and so forth, and that from such the individual sensible things that we see are constituted, in so far as in corporeal matter there abides the impression received from these separate forms, by a kind of assimilation, or as he calls it, participation Phaedo xlix).
And, according to the Platonists, the order of forms corresponds to the order of those separate substances; for example, that there is a single separate substance, which is horse and the cause of all horses, whilst above this is separate life, or per se life, as they term it, which is the cause of all life, and that above this again is that which they call being itself, which is the cause of all being. Avicenna, however, and certain others, have maintained that the forms of corporeal things do not subsist per se in matter, but in the intellect only.
Thus they say that from forms existing in the intellect of spiritual creatures called intelligences by them, but angels by us) proceed all the forms of corporeal matter, as the form of his handiwork proceeds from the forms in the mind of the craftsman. This theory seems to be the same as that of certain heretics of modern times, who say that God indeed created all things, but that the devil formed corporeal matter, and differentiated it into species. But all these opinions seem to have a common origin; they all, in fact, sought for a cause of forms as though the form were of itself brought into being.
Whereas, as Aristotle Metaph. vii, text. 26, 27, 28), proves, what is, properly speaking, made, is the composite. Now, such are the forms of corruptible things that at one time they exist and at another exist not, without being themselves generated or corrupted, but by reason of the generation or corruption of the composite; since even forms have not being, but composites have being through forms: for, according to a thing's mode of being, is the mode in which it is brought into being.
Since, then, like is produced from like, we must not look for the cause of corporeal forms in any immaterial form, but in something that is composite, as this fire is generated by that fire. Corporeal forms, therefore, are caused, not as emanations from some immaterial form, but by matter being brought from potentiality into act by some composite agent. But since the composite agent, which is a body, is moved by a created spiritual substance, as Augustine says De Trin.
iii, 4, 5), it follows further that even corporeal forms are derived from spiritual substances, not emanating from them, but as the term of their movement. And, further still, the species of the angelic intellect, which are, as it were, the seminal types of corporeal forms, must be referred to God as the first cause. But in the first production of corporeal creatures no transmutation from potentiality to act can have taken place, and accordingly, the corporeal forms that bodies had when first produced came immediately form God, whose bidding alone matter obeys, as its own proper cause.
To signify this, Moses prefaces each work with the words, God said, Let this thing be, or that, to denote the formation of all things by the Word of God, from Whom, according to Augustine, is all form and fitness and concord of parts.
5 Respondeo dicendum quod opinio fuit quorundam quod omnes formae corporales deriventur a substantiis spiritualibus quas Angelos dicimus. Et hoc quidem dupliciter aliqui posuerunt. Plato enim posuit formas quae sunt in materia corporali, derivari et formari a formis sine materia subsistentibus, per modum participationis cuiusdam. Ponebat enim hominem quendam immaterialiter subsistentem, et similiter equum, et sic de aliis, ex quibus constituuntur haec singularia sensibilia, secundum quod in materia corporali remanet quaedam impressio ab illis formis separatis, per modum assimilationis cuiusdam, quam participationem vocabat.
Et secundum ordinem formarum ponebant Platonici ordinem substantiarum separatarum, puta quod una substantia separata est quae est equus, quae est causa omnium equorum; supra quam est quaedam vita separata, quam dicebant per se vitam et causam omnis vitae; et ulterius quandam quam nominabant ipsum esse, et causam omnis esse. Avicenna vero et quidam alii non posuerunt formas rerum corporalium in materia per se subsistere, sed solum in intellectu. A formis ergo in intellectu creaturarum spiritualium existentibus quas quidem ipsi intelligentias, nos autem Angelos dicimus), dicebant procedere omnes formas quae sunt in materia corporali, sicut a formis quae sunt in mente artificis, procedunt formae artificiatorum.
Et in idem videtur redire quod quidam moderni haeretici ponunt, dicentes quidem Deum creatorem omnium, sed materiam corporalem a Diabolo formatam et per varias species distinctam. Omnes autem hae opiniones ex una radice processisse videntur. Quaerebant enim causam formarum, ac si ipsae formae fierent secundum seipsas. Sed sicut probat Aristoteles in VII Metaphys., id quod proprie fit, est compositum, formae autem corruptibilium rerum habent ut aliquando sint, aliquando non sint, absque hoc quod ipsae generentur aut corrumpantur, sed compositis generatis aut corruptis, quia etiam formae non habent esse, sed composita habent esse per eas, sic enim alicui competit fieri, sicut et esse.
Et ideo, cum simile fiat a suo simili, non est quaerenda causa formarum corporalium aliqua forma immaterialis; sed aliquod compositum, secundum quod hic ignis generatur ab hoc igne. Sic igitur formae corporales causantur, non quasi influxae ab aliqua immateriali forma, sed quasi materia reducta de potentia in actum ab aliquo agente composito. Sed quia agens compositum, quod est corpus, movetur a substantia spirituali creata, ut Augustinus dicit III de Trin.; sequitur ulterius quod etiam formae corporales a substantiis spiritualibus deriventur, non tanquam influentibus formas, sed tanquam moventibus ad formas.
Ulterius autem reducuntur in Deum, sicut in primam causam, etiam species angelici intellectus, quae sunt quaedam seminales rationes corporalium formarum. In prima autem corporalis creaturae productione non consideratur aliqua transmutatio de potentia in actum. Et ideo formae corporales quas in prima productione corpora habuerunt, sunt immediate a Deo productae, cui soli ad nutum obedit materia, tanquam propriae causae. Unde ad hoc significandum, Moyses singulis operibus praemittit, dixit Deus fiat hoc vel illud; in quo significatur formatio rerum per verbum Dei facta, a quo, secundum Augustinum, est omnis forma et compago et concordia partium.
6 Reply to Objection 1: By immaterial forms Boethius understands the types of things in the mind of God. Thus the Apostle says Heb. 11, 3): By faith we understand that the world was framed by the Word of God; that from invisible things visible things might be made. But if by immaterial forms he understands the angels, we say that from them come material forms, not by emanation, but by motion.
6 Ad primum ergo dicendum quod Boetius intelligit per formas quae sunt sine materia, rationes rerum quae sunt in mente divina, sicut etiam apostolus dicit, Heb. XI, fide credimus aptata esse saecula verbo Dei, ut ex invisibilibus visibilia fierent. Si tamen per formas quae sunt sine materia, intelligit Angelos, dicendum est quod ab eis veniunt formae quae sunt in materia, non per influxum, sed per motum.
7 Reply to Objection 2: Forms received into matter are to be referred, not to self-subsisting forms of the same type, as the Platonists held, but either to intelligible forms of the angelic intellect, from which they proceed by movement, or, still higher, to the types in the Divine intellect, by which the seeds of forms are implanted in created things, that they may be able to be brought by movement into act.
7 Ad secundum dicendum quod formae participatae in materia reducuntur, non ad formas aliquas per se subsistentes rationis eiusdem, ut Platonici posuerunt; sed ad formas intelligibiles vel intellectus angelici, a quibus per motum procedunt; vel ulterius ad rationes intellectus divini, a quibus etiam formarum semina sunt rebus creatis indita, ut per motum in actum educi possint.
8 Reply to Objection 3: The heavenly bodies inform earthly ones by movement, not by emanation.
8 Ad tertium dicendum quod corpora caelestia causant formas in istis inferioribus, non influendo, sed movendo.
