1 Objection 1: It would seem that free-will is not a power. For free-will is nothing but a free judgment. But judgment denominates an act, not a power. Therefore free-will is not a power.
1 Ad secundum sic proceditur. Videtur quod liberum arbitrium non sit potentia. Arbitrium enim liberum nihil est aliud quam liberum iudicium. Iudicium autem non nominat potentiam, sed actum. Ergo liberum arbitrium non est potentia.
2 Objection 2: Further, free-will is defined as the faculty of the will and reason. But faculty denominates a facility of power, which is due to a habit. Therefore free-will is a habit. Moreover Bernard says De Gratia et Lib. Arb. 1, 2) that free-will is the soul's habit of disposing of itself. Therefore it is not a power.
2 Praeterea, liberum arbitrium dicitur esse facultas voluntatis et rationis. Facultas autem nominat facilitatem potestatis, quae quidem est per habitum. Ergo liberum arbitrium est habitus. Bernardus etiam dicit quod liberum arbitrium est habitus animae liber sui. Non ergo est potentia.
3 Objection 3: Further, no natural power is forfeited through sin. But free-will is forfeited through sin; for Augustine says that man, by abusing free-will, loses both it and himself. Therefore free-will is not a power.
3 Praeterea, nulla potentia naturalis tollitur per peccatum. Sed liberum arbitrium tollitur per peccatum, Augustinus enim dicit quod homo male utens libero arbitrio, et se perdit et ipsum. Ergo liberum arbitrium non est potentia.
4 On the contrary, Nothing but a power, seemingly, is the subject of a habit. But free-will is the subject of grace, by the help of which it chooses what is good. Therefore free-will is a power.
4 Sed contra est quod nihil est subiectum habitus, ut videtur, nisi potentia. Sed liberum arbitrium est subiectum gratiae; qua sibi assistente, bonum eligit. Ergo liberum arbitrium est potentia.
5 I answer that, Although free-will in its strict sense denotes an act, in the common manner of speaking we call free-will, that which is the principle of the act by which man judges freely. Now in us the principle of an act is both power and habit; for we say that we know something both by knowledge and by the intellectual power. Therefore free-will must be either a power or a habit, or a power with a habit. That it is neither a habit nor a power together with a habit, can be clearly proved in two ways.
First of all, because, if it is a habit, it must be a natural habit; for it is natural to man to have a free-will. But there is not natural habit in us with respect to those things which come under free-will: for we are naturally inclined to those things of which we have natural habits, for instance, to assent to first principles: while those things which we are naturally inclined are not subject to free-will, as we have said of the desire of happiness Question 82, Articles 1, 2).
Wherefore it is against the very notion of free-will that it should be a natural habit. And that it should be a non-natural habit is against its nature. Therefore in no sense is it a habit. Secondly, this is clear because habits are defined as that by reason of which we are well or ill disposed with regard to actions and passions Ethic. ii, 5); for by temperance we are well-disposed as regards concupiscences, and by intemperance ill-disposed: and by knowledge we are well-disposed to the act of the intellect when we know the truth, and by the contrary ill-disposed.
But the free-will is indifferent to good and evil choice: wherefore it is impossible for free-will to be a habit. Therefore it is a power.
5 Respondeo dicendum quod, quamvis liberum arbitrium nominet quendam actum secundum propriam significationem vocabuli; secundum tamen communem usum loquendi, liberum arbitrium dicimus id quod est huius actus principium, scilicet quo homo libere iudicat. Principium autem actus in nobis est et potentia et habitus, dicimur enim aliquid cognoscere et per scientiam, et per intellectivam potentiam. Oportet ergo quod liberum arbitrium vel sit potentia, vel sit habitus, vel sit potentia cum aliquo habitu. Quod autem non sit habitus, neque potentia cum habitu, manifeste apparet ex duobus.
Primo quidem, quia si est habitus, oportet quod sit habitus naturalis, hoc enim est naturale homini, quod sit liberi arbitrii. Nullus autem habitus naturalis adest nobis ad ea quae subsunt libero arbitrio, quia ad ea respectu quorum habemus habitus naturales, naturaliter inclinamur, sicut ad assentiendum primis principiis; ea autem ad quae naturaliter inclinamur, non subsunt libero arbitrio, sicut dictum est de appetitu beatitudinis. Unde contra propriam rationem liberi arbitrii est, quod sit habitus naturalis. Contra naturalitatem autem eius est, quod sit habitus non naturalis.
Et sic relinquitur quod nullo modo sit habitus. Secundo hoc apparet, quia habitus dicuntur secundum quos nos habemus ad passiones vel ad actus bene vel male, ut dicitur in II Ethic., nam per temperantiam bene nos habemus ad concupiscentias, per intemperantiam autem male; per scientiam etiam bene nos habemus ad actum intellectus, dum verum cognoscimus per habitum autem contrarium male. Liberum autem arbitrium indifferenter se habet ad bene eligendum vel male. Unde impossibile est quod liberum arbitrium sit habitus. Relinquitur ergo quod sit potentia.
6 Reply to Objection 1: It is not unusual for a power to be named from its act. And so from this act, which is a free judgment, is named the power which is the principle of this act. Otherwise, if free-will denominated an act, it would not always remain in man.
6 Ad primum ergo dicendum quod consuetum est potentiam significari nomine actus. Et sic per hunc actum qui est liberum iudicium, nominatur potentia quae est huius actus principium. Alioquin, si liberum arbitrium nominaret actum, non semper maneret in homine.
7 Reply to Objection 2: Faculty sometimes denominates a power ready for operation, and in this sense faculty is used in the definition of free-will. But Bernard takes habit, not as divided against power, but as signifying a certain aptitude by which a man has some sort of relation to an act. And this may be both by a power and by a habit: for by a power man is, as it were, empowered to do the action, and by the habit he is apt to act well or ill.
7 Ad secundum dicendum quod facultas nominat quandoque potestatem expeditam ad operandum. Et sic facultas ponitur in definitione liberi arbitrii. Bernardus autem accipit habitum non secundum quod dividitur contra potentiam, sed secundum quod significat habitudinem quandam, qua aliquo modo se aliquis habet ad actum. Quod quidem est tam per potentiam quam per habitum, nam per potentiam homo se habet ut potens operari, per habitum autem ut aptus ad operandum bene vel male.
8 Reply to Objection 3: Man is said to have lost free-will by falling into sin, not as to natural liberty, which is freedom from coercion, but as regards freedom from fault and unhappiness. Of this we shall treat later in the treatise on Morals in the second part of this work FS, Question 85, seqq.; Question 109).
8 Ad tertium dicendum quod homo peccando liberum arbitrium dicitur perdidisse, non quantum ad libertatem naturalem, quae est a coactione; sed quantum ad libertatem quae est a culpa et a miseria. De qua infra in tractatu moralium dicetur, in secunda parte huius operis.
