Preliminary Notes
Note 1° that among the various acceptations of liberty two especially are distinguished.
Nota 1° inter varias acceptiones libertatis duplicem potissimum distingui.
The first is liberty from violence or coercion, and it is called spontaneity or free inclination. It is found in all who act not compelled by external force, but from inclination, even though necessitating. With this liberty the blessed love God, and God loves himself. It extends even to brute animals, nay even to inanimate things. Thus water is said to flow spontaneously, the stone to descend downward of itself.
Prima est libertas a violentia seu coactione, et dicitur spontaneitas seu lubentia. Reperitur in omnibus qui non per vim extrinsecam compulsi, sed ex inclinatione, quamvis necessitante, agunt. Hac libertate beati amant Deum, Deus amat seipsum. Extenditur etiam ad bruta, quin imo et ad res inanimatas. Sic aqua dicitur sponte fluere, lapis sponte descendere deorsum.
The second liberty is from necessity, and it is immunity not only from coercion or violence, but also from natural instinct and determination to one thing without power toward the opposite : with which liberty he enjoys who can will or not will, will this or that. It is called the liberty of indifference, because it is toward opposites. And since indifference is twofold, namely as regards specification and exercise, so liberty from necessity is twofold, namely of specification and of exercise. Liberty of exercise, which is also called liberty of contradiction, is toward an act and its omission, whereby indeed one can act and not act, love and not love. Liberty of specification is toward acts specifically diverse, which acts, if they be contraries, as to love and to hate, to sit and to stand, is called liberty of contrariety; if they be disparate acts, as to pray or to study, it is called liberty of disparity. That the liberty of the will lies in this liberty from necessity we now suppose, and we shall prove below.
Secunda libertas est a necessitate, et est immunitas, non solum a coactione seu violentia, sed etiam a naturali instinctu et determinatione ad unum sine potentia ad oppositum : qua libertate gaudet qui potest velle vel non velle, hoc vel illud velle. Dicitur libertas indifferentiae, quia est ad opposita. Et cum sit duplex indifferentia, scilicet quoad specificationem et exercitium, ita est duplex libertas a necessitate, scilicet specificationis et exercitii. Libertas exercitii, quae etiam dicitur contradictionis, est ad actum et ejus omissionem, qua nempe potest quis agere et non agere, amare et non amare. Libertas specificationis est ad actus specie diversos, qui actus si sint contrarii, ut amare et odisse, sedere et stare, dicitur libertas contrarietatis; si sint actus disparati, ut orare vel studere, dicitur libertas disparitatis. In hac libertate a necessitate sitam esse libertatem arbitrii nunc supponimus, et infra probabimus.
Note 2° the various errors concerning free will. The Stoics denied it, from fate; the astrologers, from the influx of the stars; the Manichaeans, from a twofold soul, one good, the other evil, one of which necessarily coerced the other by this very fact that it prevailed; the Wiclefites, Lutherans and Calvinists, from original sin and from the force of necessitating grace; Baius and Jansenius1, from the same principles. 1 Baius said : « What is done voluntarily, although it be done necessarily, is nevertheless done freely. » This is his proposition 39, condemned by St. Pius V. « Only violence is repugnant to the liberty of man. » It is proposition 66. — Jansenius, lib. IV de Statu naturae lapsae, c. 24 : for Augustine « it is abundantly enough that the sinner... knowing and prudent, be borne into evil with full will, whether he can extricate himself from that necessity of loving the evil, or cannot. » He teaches the same in lib. IV de Gratia Christi, c. 9, that, « with carnal delectation prevailing, it is impossible that the consideration of virtue and honesty should prevail. » And he draws this also from that saying of St. Augustine which he repeats a thousand times and badly understands, in cap. v Epist. ad Galat. : « By what we are more delighted, according to that it behooves us to work, »
Nota 2° varios errores circa libertatem arbitrii. Hanc negarunt Stoici, ex fato; astrologi, ex influxu siderum; Manichaei, ex duplici anima, una bona, altera mala, quarum una alteram necessario compellebat hoc ipso quo praevalebat; Wiclefistae, Lutherani et Calvinistae, ex peccato originali et ex vi necessitantis gratiae; Baius et Jansenius1, ex iisdem principiis. 1 Baius dixit : « Quod voluntarie fit, etsi necessario fiat, libere tamen fit. » Est ejus propositio 39, a S. Pio V damnata. « Sola violentia repugnat libertati hominis. » Est propositio 66. — Jansenius, lib. IV de Statu naturae lapsae, c. 24 : Augustino « abunde satis est quod peccator... sciens et prudens plena voluntate feratur in malum, sive ab ista diligendi mali necessitate se expedire possit, sive non possit. » Idem docet lib. IV de Gratia Christi, c. 9, quod, « vigente delectatione carnali, impossibile sit ut virtutis ac honestatis consideratio praevaleat. » Et hoc etiam deducit ex illo, quod millies repetit et male intelligit, S. Augustini effato, in cap. v Epist. ad Galat. : « Quod amplius nos delectat, secundum id operemur necesse est, »
As regards Jansenius, it must be observed that he admits verbatim a liberty of the will compatible with necessity. He says therefore that the liberty of the will, which he calls essential, is compatible with a necessity fixed, invariable and perpetual, which can vary in no circumstances, such as that by which God loves himself, by which the blessed love God. The liberty of the will as regards the present state of man wayfarer he says subsists with a necessity not fixed and invariable, but transitory and relative, which, the present circumstances standing, relatively to a superior opposing force cannot be overcome, although absolutely and in other circumstances it could be overcome. Whence the whole liberty of the will which Jansenius acknowledges in this state of fallen nature is nothing else than alternative necessity, or turnability from one necessity to another; because wayfarers are not immovably fixed in evil, like the damned, but flexible now toward good, now toward evil, according as celestial or earthly delectation prevails, yet always necessarily : in almost the manner in which a dog now fawns, now grows angry, yet always necessarily.
Quantum ad Jansenium, observandum est ipsum verbotenus admittere libertatem arbitrii, quae stet cum necessitate. Dicit itaque libertatem arbitrii, quam vocat essentialem, consistere cum necessitate fixa invariabili et perpetua, quae in nullis circumstantiis variari potest, qualis est ista qua Deus se diligit, qua beati amant Deum. Libertatem arbitrii quoad statum praesentem hominis viatoris dicit subsistere cum necessitate, non fixa et invariabili, sed transitoria et relativa, quae nempe stantibus praesentibus circumstantiis relative ad vim oppositam superiorem vinci non potest, licet absolute et in aliis circumstantiis vinci posset. Unde tota libertas arbitrii quam agnoscit Jansenius in hoc statu naturae lapsae, nihil est aliud quam necessitas alternativa, seu vertibilitas ab una ad aliam necessitatem; quia viatores non sunt immobiliter fixi in malo, sicut damnati, sed flexibiles modo in bonum, modo in malum, secundum quod praevalet delectatio coelestis aut terrestris, semper tamen necessario : eo ferme modo quo canis modo blanditur, modo irascitur, semper tamen necessario.
1 1 Baius said : « What is done voluntarily, although it be done necessarily, is nevertheless done freely. » This is his proposition 39, condemned by St. Pius V. « Only violence is repugnant to the liberty of man. » It is proposition 66. — Jansenius, lib. IV de Statu naturae lapsae, c. 24 : for Augustine « it is abundantly enough that the sinner... knowing and prudent, be borne into evil with full will, whether he can extricate himself from that necessity of loving the evil, or cannot. » He teaches the same in lib. IV de Gratia Christi, c. 9, that, « with carnal delectation prevailing, it is impossible that the consideration of virtue and honesty should prevail. » And he draws this also from that saying of St. Augustine which he repeats a thousand times and badly understands, in cap. v Epist. ad Galat. : « By what we are more delighted, according to that it behooves us to work, »
1 1 Baius dixit : « Quod voluntarie fit, etsi necessario fiat, libere tamen fit. » Est ejus propositio 39, a S. Pio V damnata. « Sola violentia repugnat libertati hominis. » Est propositio 66. — Jansenius, lib. IV de Statu naturae lapsae, c. 24 : Augustino « abunde satis est quod peccator... sciens et prudens plena voluntate feratur in malum, sive ab ista diligendi mali necessitate se expedire possit, sive non possit. » Idem docet lib. IV de Gratia Christi, c. 9, quod, « vigente delectatione carnali, impossibile sit ut virtutis ac honestatis consideratio praevaleat. » Et hoc etiam deducit ex illo, quod millies repetit et male intelligit, S. Augustini effato, in cap. v Epist. ad Galat. : « Quod amplius nos delectat, secundum id operemur necesse est, »
On the other hand the Pelagians erred concerning free will, extolling it too much. They said 1° that it avails toward good just as toward evil without the grace of God; 2° that it cannot stand together with the necessity of preventing grace; 3° that Jesus was in no way touched by the sin of Adam, which they denied was transmitted to posterity; but that, placed as it were in equilibrium, he had equal indifference and facility either toward good or toward evil, as in the state of innocence; 4° they wished the power of sinning to belong to the essence of liberty.
Ex adverso Pelagiani erraverunt circa libertatem arbitrii, nimium illud extollendo. Dicebant 1° ipsum valere ad bonum sicut ad malum sine gratia Dei; 2° stare non posse cum necessitate gratiae pravenientis; 3° in nullo fuisse Iesum per peccatum Adae, quod negabant traduci in posteros; sed veluti in aequilibrio positum parem habere indifferentiam et facilitatem, sive ad bonum, sive ad malum, ac in statu innocentiae; 4° volebant potentiam peccandi pertinere ad essentiam libertatis.
Note 3° that there is a twofold root of liberty, one external, the other intrinsic. The intrinsic root of liberty is the supreme efficacy of the divine will1 ; because, since God is the most universal cause of all being and all its modes, and the liberty of the will, both potential and actual, is one of its modes and perfections, as well as of all its actions, it plainly follows that liberty flows from the efficacy of the divine will, as from an external root. 1 Ia p., q. 19, a. 8, c.
Nota 3° duplicem esse radicem libertatis, unam extrinsecam, aliam intrinsecam. Radix intrinseca libertatis est summa efficacia divinae voluntatis1; quia, cum Deus sit causa universalissima totius entis et omnium ejus modorum, et libertas tam potentialis quam actualis arbitrii sit ejus modus et perfectio, atque omnium ejus actionum, plane sequitur quod ab efficacia divina voluntatis, tanquam a radice extrinseca, profluat. 1 1. p., q. 19, a. 8, c.
The intrinsic root of liberty is threefold. The first and remote is the very condition of intellectual nature2 , which, on account of its immateriality, obtains that capacity that, without alteration of itself, it can receive within itself the forms of all things and become all things in intentional being. Hence follows the universality of the intellect, by which it can know all things, search them out, examine them, turn itself in all directions, judge of them what is to be fled, what pursued, likewise reflect upon its own judgment above itself, amend it, change it and reprove it. And this is the second intrinsic root of liberty. Now upon this universal intellectual form follows the inclination of like condition, namely the will capable of every universal and infinite good, and its eminence above all particular goods. And this is the third and proximate root of liberty; for from it there results in the will dominion over its own acts, and the right of disposing of them at a nod, in which formally consists the liberty of the will. 2 Ia p., q. 14, a. 1, c ; q. 82, a. 2, c ; q. 24 de Verit., a. 2 ; q. 6 de Malo, a. unico, and elsewhere.
Radix libertatis intrinseca est triplex. Prima et remota est ipsa conditio naturae intellectualis2, quae, ob suam immaterialitatem, eam obtinet capacitatem ut, absque sui alteratione, possit omnium formas in se recipere et fieri omnia in esse intentionali. Hinc sequitur universalitas intellectus, qua potest omnia cognoscere, scrutari, rimari, et in omnes partes vertere, de iisque judicare quae fugienda, quae prosequenda, item supra ipsum judicium reflectere, illud emendare, mutare et reprobare. Et haec est secunda radix intrinseca libertatis. Hanc autem formam universalem intellectualem sequitur inclinatio paris conditionis, scilicet voluntas capax omnis universalis et infiniti boni, ejusque eminentia super omnia bona particularia. Et haec est tertia et proxima radix libertatis; inde enim resultat in voluntate dominium super suos actus, ac jus disponendi de illis ad nutum, in quo consistit formaliter libertas arbitrii. 2 1. p., q. 14, a. 1, c; q. 82, a. 2, c; q. 24 de Verit., a. 2; q. 6 de Malo, a. unico, et alibi.
Note 4° that among the various definitions of liberty which St. Thomas hands down, the following is more frequently used by him, and is the best1 , namely : « The elective power of means, the order of the end being preserved. » 1 Ia p., q. 62, a. 8, ad 3 and q. 83, a. 4, c, and elsewhere.
Nota 4° inter varias libertatis definitiones quas tradit S. Thomas sequentem ab ipso frequentius usurpari, et esse optimam1, scilicet : « Vis electiva mediorum, servato ordine finis. » 1 1. p., q. 62, a. 8, ad 3 et q. 83, a. 4, c, et alibi.
It is explained. It is called power, that is, faculty or active potency. It is called elective power, because from this we are said to have free will, that we can take one thing, another refused; which is to choose. It is called elective power of means, because election properly is not about the end as end2 , but only about means; because election, in things doable, stands to them as conclusion stands in things speculative, and the end as principle; whence, as conclusion is not about principles, but about their consequences, so election is not about the end, but about the means to it. I said, « about the end as end; » because, as in speculative matters nothing hinders what is the principle of one demonstration from being the conclusion of another demonstration (yet the first principle among demonstrables cannot be the conclusion of another demonstration), so also it happens that what is as end in one operation is ordered to something else as to an end, and in this way the end falls under election : thus, in the operation of a physician, health stands as end, whence it does not fall under the physician's election, but he supposes it as principle; but bodily health is ordered to the good of the soul, whence for him who has care of the salvation of the soul, being healthy or being sick can fall under election. But the last end falls under election in no way, because it cannot be ordered to anything else. 2 Here q. 13, a. 3, c.
Explicatur. Dicitur vis, id est facultas seu potentia activa. Dicitur vis electiva, quia ex hoc liberi arbitrii esse dicimur, quod possumus unum accipere, alio recusato; quod est eligere. Dicitur vis electiva mediorum, quia electio proprie non est de fine ut finis est2, sed de mediis tantum; quia electio, in operabilibus, se habet ut conclusio in speculabilibus, et finis sicut principium; unde, sicut non est conclusio de principiis, sed de consequentibus ad illa, ita electio non est de fine, sed de mediis ad illum. Dixi, « de fine, ut finis est; » quia, sicut in speculativis nihil prohibet id quod est unius demonstrationis principium esse conclusionem alterius demonstrationis (primum tamen principium in demonstrabilibus non potest esse conclusio alterius demonstrationis), ita etiam contingit id quod est in una operatione ut finis, ordinari ad aliquid aliud ut ad finem, et hoc modo finis cadit sub electione : sicut, in operatione medici, sanitas se habet ut finis, unde hoc non cadit sub electione medici, sed hoc supponit tanquam principium; sed sanitas corporis ad bonum animae ordinatur, unde apud eum qui habet curam de animae salute, potest sub electione cadere esse sanum, vel esse infirmum. Sed ultimus finis nullo modo sub electione cadit, quia non potest ordinari ad aliud. 2 Hic q. 13, a. 3, c.
It is called, the order of the end being preserved ; because free will stands to choosing those things that are toward the end as intellect stands to the conclusion. But it is manifest that it pertains to the power of the intellect that it can proceed into various conclusions according to given principles; but that it proceed into some conclusion passing over the order of principles, this is from its defect. Similarly therefore, that free will can choose various things while preserving the order of the end, this pertains to the perfection of liberty; but that it choose something turning aside from the order of the end, this pertains to the defect of liberty. Whence the liberty of the will is greater and more perfect in God, in Christ and in the angels, who cannot sin, than in us, who can sin. And hence already it is clear that the power of sinning is not of the essence of liberty, but is its blemish : of which again below.
Dicitur, servato ordine finis ; quia liberum arbitrium sic se habet ad eligendum ea quae sunt ad finem, sicut se habet intellectus ad conclusionem. Manifestum est autem quod ad virtutem intellectus pertinet, ut in diversas conclusiones procedere possit secundum principia data; sed quod in aliquam conclusionem procedat praetermittendo ordinem principiorum, hoc est ex defectu ipsius. Similiter ergo, quod liberum arbitrium diversa eligere possit servato ordine finis, hoc pertinet ad perfectionem libertatis; sed quod eligat aliquid divertendo ab ordine finis, hoc pertinet ad defectum libertatis. Unde major et perfectior est libertas arbitrii in Deo, Christo et angelis, qui peccare non possunt, quam in nobis, qui peccare possumus. Et hinc jam patet, potentiam peccandi non esse de essentia libertatis, sed esse ejus naevum : de quo iterum infra.
The other definition, now very commonly circulated, of liberty, is namely : « The faculty by which, all prerequisites for acting being posited, one can act or not act. » Truly that definition is ambiguous, and put forward by those who reject physical premotions. If then it be understood of the requisites temporally prior to acting, we admit it, both in the composite and divided sense, both of consequent and antecedent potency. But if it be understood of the requisites naturally prior only to acting, we do not admit it except in the divided sense and of antecedent potency for not acting; because, in this very instant in which the requisites for acting exist naturally only, there is action, and so with requisites of this kind for acting there remains indeed a potency for not acting, but it cannot conjoin non-act with them. Whence, according to this sense, it is improperly said in the definition, « by which one can act or not act », but it ought to be said, ibid. « which actually acts with the potency of not acting. »
Altera et nunc valde communis circumfertur definitio libertatis, scilicet : « Facultas qua, positis omnibus ad agendum praerequisitis, potest agere vel non agere. » Verum ista definitio est ambigua et ab eis prolata qui rejiciunt praemotiones physicas. Si itaque intelligatur de requisitis tempore ad agendum, eam admittimus, tam in sensu composito quam diviso, tam de potentia consequente quam antecedente. Si vero intelligatur de requisitis natura tantum ad agendum, eam non admittimus, nisi in sensu diviso et de potentia non agendi antecedente; quia, hoc ipso instanti quo sunt requisita tantum natura ad agendum, est actio, sicque cum hujusmodi requisitis ad agendum remanet quidem potentia ad non agendum, non tamen conjugendi non actum cum illis. Unde, juxta hunc sensum, improprie dicitur in definitione, « qua potest agere vel non agere » sed debet dici, ibid. « quae actu agit cum potentia non agendi. »
Therefore R. P. Franciscus Henno was gravely hallucinated when, tract. de Principiis actuum humanorum, q. 3, he wrote that Thomists teach a physical premotion, « while it stands, non-action cannot be, unless in the divided sense of premotion, that is, premotion taken away, » and similar things. This doctrine is Calvinian, not Thomistic. For the Thomists teach that, the premotion to act standing, and in the composite sense of premotion, there remains a complete and expedite potency for non-act, because premotion supposes on both sides the complete potency, and holds itself only on the side of second act.
Graviter igitur hallucinatus est R. P. Franciscus Henno, dum, tract. de Principiis actuum humanorum, q. 3, scripsit Thomistas docere praemotionem physicam, « qua stante, non possit esse non actio, nisi in sensu diviso praemotionis, id est, ablata praemotione, » et similia. Haec doctrina est Calviniana, non Thomistica. Docent namque Thomistae, stante praemotione ad actum et in sensu composito praemotionis, manere potentiam completam et expeditam ad non actum, quia praemotio supponit utrinque potentiam completam, et se tenet dumtaxat ex parte actus secundi.
Note 5° that it does not pertain to free will to be the first determiner.
Nota 5° non pertinere ad liberum arbitrium ut sit primum determinans.
It is evident, first, from the nature of created being, to which dependence both in being and in operating upon uncreated being is so essential that it can by no reason be torn from it; since indeed the character of created being cannot be conceived, nor any of its perfections, which does not arise from God and depend upon him. Whence God is called not only first being, but first cause, first principle, first mover, first determiner, first free; because, as no being exists except participated from him, so no cause, no mover, no determiner, no free agent, except subordinated to him. And as, if there were some being not participated from him, it would cease to be first being; so, if the will were the first mover and determiner of itself, it would cease to be first cause, first principle, first mover, first free, and a creature would be adorned with these prerogatives, and would become as it were another God; for first is said of that which supposes no other prior.
Constat, primo, ex natura entis creati, cui dependentia tam in esse quam in operari ab ente increato ita est essentialis, ut nulla ratione ab ipso avelli possit; si quidem concipi non possit ratio entis creati, aut ulla ejus perfectio, quae a Deo non oriatur et dependeat. Unde Deus dicitur, non solum primum ens, sed prima causa, primum principium, primum movens, primum determinans, primum liberum; quia, sicut nullum est ens, nisi ab eo participatum, ita nulla causa, nullum movens, nullum determinans, nullum liberum, nisi ipsi subordinatum. Et sicut, si esset aliquod ens ab ipso non participatum, desineret esse primum ens; sic, si voluntas esset primum sui movens et determinans, desineret esse prima causa, primum principium, primum movens, primum liberum, et creatura his praerogativis decoraretur, fieretque quasi alter Deus; primum enim dicitur, quod alterum prius non supponit.
Neither say you, with the adversaries, that although the will determined itself first, it would not therefore be the first cause and first principle; because the character of first cause and first principle requires not only that it be not moved by another, but also that it be from itself. This character indeed St. Thomas attacks as false in II Sentent., dist. 37, q. 2, a. 2, c. Because, he says, « it seems unfitting that what has not being from itself can act from itself...; for all power proceeds from essence, and operation from power. Whence whose essence is from another, his power and operation must be from another. » He adds : « Besides, although by this answer it were avoided that it not be simply first, still it could not be avoided that it be the first agent, if its action were not reduced to some prior agent, as to cause. »
Neque dicas, cum adversariis, voluntatem quamvis primo se determinaret, non ideo fore primam causam et primum principium; quia ratio prima causae et primi principii exigit, non solum quod ab altero non moveatur, sed etiam quod sit a se. Hanc enim rationem tamquam falsam impugnat S. Thomas in II Sentent., dist. 37, q. 2, a. 2, c. Quia, inquit, « inconveniens videtur ut quod a se esse non habet, a se agere possit...; quia omnis virtus ab essentia procedit, et operatio a virtute. Unde cujus essentia ab alio est, oportet quod virtus et operatio sit ab alio. » Addit : « Praeterea, quamvis per hanc responsionem vitaretur quod non esset primum simpliciter, non posset tamen vitari quin esset primum agens, si ejus actio in aliquod prius agens non reduceretur, sicut in causam. »
It is evident, secondly, from observation, because nothing forbids the will to be first moved and determined by God, if under that motion of God it also moves and determines itself, and so preserves its liberty, and the character of praise and merit. For the adversaries deny that the will is first determined by God for no other reason than that they think, under that determination, the will does not move and determine itself, but is so determined to one that the opposite is not possible, and so is despoiled of its liberty. But it is thus that under the determination of God the will itself moves and determines itself. For to what purpose is given that motion and determination of God? Certainly not that the will do nothing, but that it act in a manner consonant to itself, that is, freely, so that it can act and not act. Whence the divine motion and determination not only does not prevent the will from moving and determining itself, but rather effects this very thing, that under that motion and determination it moves and determines itself. Therefore.
Constat secundo observatione, quia nihil vetat voluntatem a Deo primo moveri et determinari, si ipsa sub ista Dei motione se etiam moveat atque determinet, sicque suam libertatem servet, et rationem laudis et meriti. Non enim alia ratione adversarii negant voluntatem a Deo primum determinari, quam quia putant, sub ea determinatione voluntatem non se movere ac determinare, sed ita determinari ad unum, ut non possit oppositum, sicque sua libertate spoliari. Atqui sic est quod sub Dei determinatione ipsa voluntas se moveat ac determinet. Ad quid enim datur ista motio ac determinatio divina? Non certe ut voluntas nihil agat, sed ut agat modo sibi consentaneo, id est libere, ita ut possit agere et non agere. Unde divina motio et determinatio non solum non impedit quin voluntas se moveat ac determinet, sed potius hoc ipsum facit, quod sub ista motione ac determinatione se moveat ac determinet. Ergo.
And this is the constant and perpetual doctrine of D. Thomas in all his works. Ia p., q. 83, a. 1, ad 3 : « Free will, he says, is the cause of its own motion, because man by free will moves himself to act. Not however is it of the necessity of liberty, that that which is free be the first cause of itself : as neither for a thing to be the cause of another is it required that it be the first cause of it. God therefore is the first moving cause both of natural causes and of voluntary ones. And as by moving natural causes he does not take away that their actions be natural; so, by moving voluntary causes, he does not take away that their actions be voluntary, but rather he effects this in them; for he operates in each thing according to its property. »
Et haec est constans et perpetua D. Thomae doctrina in omnibus suis operibus. 1 p., q. 83, a. 1, ad 3 : « Liberum arbitrium, inquit, est causa sui motus, quia homo per liberum arbitrium seipsum movet ad agendum. Non tamen hoc est de necessitate libertatis, quod sit prima causa sui id quod liberum est : sicut nec ad hoc quod aliquid sit causa alterius, requiritur quod sit prima causa ejus. Deus igitur est prima causa movens et naturales causas et voluntarias. Et sicut naturalibus causis, movendo eas, non aufert quin actiones earum sint naturales; ita, movendo causas voluntarias, non aufert quin actiones earum sint voluntariae, sed potius hoc in eis facit; operatur enim in unoquoque secundum ejus proprietatem. »
