1 Objection 1: It would seem that sensuality is not only appetitive, but also cognitive. For Augustine says De Trin. xii, 12) that the sensual movement of the soul which is directed to the bodily senses is common to us and beasts. But the bodily senses belong to the apprehensive powers. Therefore sensuality is a cognitive power.
1 Ad primum sic proceditur. Videtur quod sensualitas non solum sit appetitiva, sed etiam cognitiva. Dicit enim Augustinus, XII de Trin., quod sensualis animae motus, qui in corporis sensus intenditur, nobis pecoribusque communis est. Sed corporis sensus sub vi cognitiva continentur. Ergo sensualitas est vis cognitiva.
2 Objection 2: Further, things which come under one division seem to be of one genus. But Augustine De Trin. xii, 12) divides sensuality against the higher and lower reason, which belong to knowledge. Therefore sensuality also is apprehensive.
2 Praeterea, quae cadunt sub una divisione, videntur esse unius generis. Sed Augustinus, in XII de Trin., dividit sensualitatem contra rationem superiorem et inferiorem; quae ad cognitionem pertinent. Ergo sensualitas etiam est vis cognitiva.
3 Objection 3: Further, in man's temptations sensuality stands in the place of the serpent. But in the temptation of our first parents, the serpent presented himself as one giving information and proposing sin, which belong to the cognitive power. Therefore sensuality is a cognitive power.
3 Praeterea, sensualitas in tentatione hominis tenet locum serpentis. Sed serpens in tentatione primorum parentum se habuit ut nuntians et proponens peccatum; quod est vis cognitivae. Ergo sensualitas est vis cognitiva.
4 On the contrary, Sensuality is defined as the appetite of things belonging to the body.
4 Sed contra est quod sensualitas definitur esse appetitus rerum ad corpus pertinentium.
5 I answer that, The name sensuality seems to be taken from the sensual movement, of which Augustine speaks De Trin. xii, 12, 13), just as the name of a power is taken from its act; for instance, sight from seeing. Now the sensual movement is an appetite following sensitive apprehension. For the act of the apprehensive power is not so properly called a movement as the act of the appetite: since the operation of the apprehensive power is completed in the very fact that the thing apprehended is in the one that apprehends: while the operation of the appetitive power is completed in the fact that he who desires is borne towards the thing desirable. Therefore the operation of the apprehensive power is likened to rest: whereas the operation of the appetitive power is rather likened to movement. Wherefore by sensual movement we understand the operation of the appetitive power: so that sensuality is the name of the sensitive appetite.
5 Respondeo dicendum quod nomen sensualitatis sumptum videtur a sensuali motu, de quo Augustinus loquitur XII de Trin., sicut ab actu sumitur nomen potentiae, ut a visione visus. Motus autem sensualis est appetitus apprehensionem sensitivam consequens. Actus enim apprehensivae virtutis non ita proprie dicitur motus, sicut actio appetitus, nam operatio virtutis apprehensivae perficitur in hoc, quod res apprehensae sunt in apprehendente; operatio autem virtutis appetitivae perficitur in hoc, quod appetens inclinatur in rem appetibilem. Et ideo operatio apprehensivae virtutis assimilatur quieti, operatio autem virtutis appetitivae magis assimilatur motui. Unde per sensualem motum intelligitur operatio appetitivae virtutis. Et sic sensualitas est nomen appetitus sensitivi.
6 Reply to Objection 1: By saying that the sensual movement of the soul is directed to the bodily senses, Augustine does not give us to understand that the bodily senses are included in sensuality, but rather that the movement of sensuality is a certain inclination to the bodily senses, since we desire things which are apprehended through the bodily senses. And thus the bodily senses appertain to sensuality as a preamble.
6 Ad primum ergo dicendum quod per hoc quod dicit Augustinus quod sensualis animae motus intenditur in corporis sensus, non datur intelligi quod corporis sensus sub sensualitate comprehendantur, sed magis quod motus sensualitatis sit inclinatio quaedam ad sensus corporis, dum scilicet appetimus ea quae per corporis sensus apprehenduntur. Et sic corporis sensus pertinent ad sensualitatem quasi praeambuli.
7 Reply to Objection 2: Sensuality is divided against higher and lower reason, as having in common with them the act of movement: for the apprehensive power, to which belong the higher and lower reason, is a motive power; as is appetite, to which appertains sensuality.
7 Ad secundum dicendum quod sensualitas dividitur contra rationem superiorem et inferiorem, inquantum communicant in actu motionis, vis enim cognitiva, ad quam pertinet ratio superior et inferior, est motiva, sicut et appetitiva, ad quam pertinet sensualitas.
8 Reply to Objection 3: The serpent not only showed and proposed sin, but also incited to the commission of sin. And in this, sensuality is signified by the serpent.
8 Ad tertium dicendum quod serpens non solum ostendit et proposuit peccatum, sed etiam, inclinavit in effectum peccati. Et quantum ad hoc, sensualitas per serpentem significatur.
