1 Objection 1: It would seem that several angels can be at the same time in the same place. For several bodies cannot be at the same time in the same place, because they fill the place. But the angels do not fill a place, because only a body fills a place, so that it be not empty, as appears from the Philosopher Phys. iv, text 52, 58). Therefore several angels can be in the one place.
1 Ad tertium sic proceditur. Videtur quod plures Angeli possint simul esse in eodem loco. Plura enim corpora non possunt esse simul in eodem loco, quia replent locum. Sed Angeli non replent locum, quia solum corpus replet locum, ut non sit vacuum, ut patet per philosophum, in IV Physic. Ergo plures Angeli possunt esse in uno loco.
2 Objection 2: Further, there is a greater difference between an angel and a body than there is between two angels. But an angel and a body are at the one time in the one place: because there is no place which is not filled with a sensible body, as we find proved in Phys. iv, text. 58. Much more, then, can two angels be in the same place.
2 Praeterea, plus differt Angelus et corpus quam duo Angeli. Sed Angelus et corpus sunt simul in eodem loco, quia nullus locus est qui non sit plenus sensibili corpore, ut probatur in IV Physic. Ergo multo magis duo Angeli possunt esse in eodem loco.
3 Objection 3: Further, the soul is in every part of the body, according to Augustine De Trin. vi). But demons, although they do not obsess souls, do obsess bodies occasionally; and thus the soul and the demon are at the one time in the same place; and consequently for the same reason all other spiritual substances.
3 Praeterea, anima est in qualibet parte corporis, secundum Augustinum. Sed Daemones, licet non illabantur mentibus, illabuntur tamen interdum corporibus, et sic anima et Daemon sunt simul in eodem loco. Ergo, eadem ratione, quaecumque aliae spirituales substantiae.
4 On the contrary, There are not two souls in the same body. Therefore for a like reason there are not two angels in the same place.
4 Sed contra, duae animae non sunt in eodem corpore. Ergo, pari ratione, neque duo Angeli in eodem loco.
5 I answer that, There are not two angels in the same place. The reason of this is because it is impossible for two complete causes to be the causes immediately of one and the same thing. This is evident in every class of causes: for there is one proximate form of one thing, and there is one proximate mover, although there may be several remote movers. Nor can it be objected that several individuals may row a boat, since no one of them is a perfect mover, because no one man's strength is sufficient for moving the boat; while all together are as one mover, in so far as their united strengths all combine in producing the one movement. Hence, since the angel is said to be in one place by the fact that his power touches the place immediately by way of a perfect container, as was said Article 1), there can be but one angel in one place.
5 Respondeo dicendum quod duo Angeli non sunt simul in eodem loco. Et ratio huius est, quia impossibile est quod duae causae completae sint immediatae unius et eiusdem rei. Quod patet in omni genere causarum, una enim est forma proxima unius rei, et unum est proximum movens, licet possint esse plures motores remoti. Nec habet instantiam de pluribus trahentibus navem, quia nullus eorum est perfectus motor, cum virtus uniuscuiusque sit insufficiens ad movendum; sed omnes simul sunt in loco unius motoris, inquantum omnes virtutes eorum aggregantur ad unum motum faciendum. Unde cum Angelus dicatur esse in loco per hoc quod virtus eius immediate contingit locum per modum continentis perfecti, ut dictum est, non potest esse nisi unus Angelus in uno loco.
6 Reply to Objection 1: Several angels are not hindered from being in the same place because of their filling the place; but for another reason, as has been said.
6 Ad primum ergo dicendum quod plures Angelos esse in uno loco non impeditur propter impletionem loci, sed propter aliam causam, ut dictum est.
7 Reply to Objection 2: An angel and a body are not in a place in the same way; hence the conclusion does not follow.
7 Ad secundum dicendum quod Angelus et corpus non eodem modo sunt in loco, unde ratio non sequitur.
8 Reply to Objection 3: Not even a demon and a soul are compared to a body according to the same relation of causality; since the soul is its form, while the demon is not. Hence the inference does not follow.
8 Ad tertium dicendum quod nec etiam Daemon et anima comparantur ad corpus secundum eandem habitudinem causae; cum anima sit forma, non autem Daemon. Unde ratio non sequitur.
