Articulus I
Whether Justice Is Fittingly Defined As Being the Perpetual and Constant Will to Render to Each One His Right?
Arg. 1 Objection 1
Ad primum sic proceditur. Videtur quod inconvenienter definiatur a iurisperitis quod iustitia est constans et perpetua voluntas ius suum unicuique tribuens. Iustitia enim, secundum philosophum, in V Ethic., est habitus a quo sunt aliqui operativi iustorum, et a quo operantur et volunt iusta. Sed voluntas nominat potentiam, vel etiam actum. Ergo inconvenienter iustitia dicitur esse voluntas.
It would seem that lawyers have unfittingly defined justice as being "the perpetual and constant will to render to each one his right" [Digest. i, 1; De Just. et Jure 10]. For, according to the Philosopher (Ethic. v, 1), justice is a habit which makes a man "capable of doing what is just, and of being just in action and in intention." Now "will" denotes a power, or also an act. Therefore justice is unfittingly defined as being a will.
Arg. 2 Objection 2
Praeterea, rectitudo voluntatis non est voluntas, alioquin, si voluntas esset sua rectitudo, sequeretur quod nulla voluntas esset perversa. Sed secundum Anselmum, in libro de veritate, iustitia est rectitudo. Ergo iustitia non est voluntas.
Further, rectitude of the will is not the will; else if the will were its own rectitude, it would follow that no will is unrighteous. Yet, according to Anselm (De Veritate xii), justice is rectitude. Therefore justice is not the will.
Arg. 3 Objection 3
Praeterea, sola Dei voluntas est perpetua. Si ergo iustitia est perpetua voluntas, in solo Deo erit iustitia.
Further, no will is perpetual save God's. If therefore justice is a perpetual will, in God alone will there be justice.
Arg. 4 Objection 4
Praeterea, omne perpetuum est constans, quia est immutabile. Superflue ergo utrumque ponitur in definitione iustitiae, et perpetuum et constans.
Further, whatever is perpetual is constant, since it is unchangeable. Therefore it is needless in defining justice, to say that it is both "perpetual" and "constant."
Arg. 5 Objection 5
Praeterea, reddere ius unicuique pertinet ad principem. Si igitur iustitia sit ius suum unicuique tribuens, sequetur quod iustitia non sit nisi in principe. Quod est inconveniens.
Further, it belongs to the sovereign to give each one his right. Therefore, if justice gives each one his right, it follows that it is in none but the sovereign: which is absurd.
Arg. 6 Objection 6
Praeterea, Augustinus dicit, in libro de moribus Eccles., quod iustitia est amor Deo tantum serviens. Non ergo reddit unicuique quod suum est.
Further, Augustine says (De Moribus Eccl. xv) that "justice is love serving God alone." Therefore it does not render to each one his right.
Respondeo I answer that
Respondeo dicendum quod praedicta iustitiae definitio conveniens est, si recte intelligatur. Cum enim omnis virtus sit habitus qui est principium boni actus, necesse est quod virtus definiatur per actum bonum circa propriam materiam virtutis. Est autem iustitia circa ea quae ad alterum sunt sicut circa propriam materiam, ut infra patebit. Et ideo actus iustitiae per comparationem ad propriam materiam et obiectum tangitur cum dicitur, ius suum unicuique tribuens, quia, ut Isidorus dicit, in libro Etymol., iustus dicitur quia ius custodit. Ad hoc autem quod aliquis actus circa quamcumque materiam sit virtuosus, requiritur quod sit voluntarius, et quod sit stabilis et firmus, quia philosophus dicit, in II Ethic., quod ad virtutis actum requiritur primo quidem quod operetur sciens, secundo autem quod eligens et propter debitum finem, tertio quod immobiliter operetur. Primum autem horum includitur in secundo, quia quod per ignorantiam agitur est involuntarium, ut dicitur in III Ethic. et ideo in definitione iustitiae primo ponitur voluntas, ad ostendendum quod actus iustitiae debet esse voluntarius. Additur autem de constantia et perpetuitate, ad designandum actus firmitatem. Et ideo praedicta definitio est completa definitio iustitiae, nisi quod actus ponitur pro habitu, qui per actum specificatur, habitus enim ad actum dicitur. Et si quis vellet in debitam formam definitionis reducere, posset sic dicere, quod iustitia est habitus secundum quem aliquis constanti et perpetua voluntate ius suum unicuique tribuit. Et quasi est eadem definitio cum ea quam philosophus ponit, in V Ethic., dicens quod iustitia est habitus secundum quem aliquis dicitur operativus secundum electionem iusti.
I answer that, The aforesaid definition of justice is fitting if understood aright. For since every virtue is a habit that is the principle of a good act, a virtue must needs be defined by means of the good act bearing on the matter proper to that virtue. Now the proper matter of justice consists of those things that belong to our intercourse with other men, as shall be shown further on (A. 2). Hence the act of justice in relation to its proper matter and object is indicated in the words, "Rendering to each one his right," since, as Isidore says (Etym. x), "a man is said to be just because he respects the rights (jus) of others."
Now in order that an act bearing upon any matter whatever be virtuous, it requires to be voluntary, stable, and firm, because the Philosopher says (Ethic. ii, 4) that in order for an act to be virtuous it needs first of all to be done "knowingly," secondly to be done "by choice," and "for a due end," thirdly to be done "immovably." Now the first of these is included in the second, since "what is done through ignorance is involuntary" (Ethic. iii, 1). Hence the definition of justice mentions first the "will," in order to show that the act of justice must be voluntary; and mention is made afterwards of its "constancy" and "perpetuity" in order to indicate the firmness of the act.
Accordingly, this is a complete definition of justice; save that the act is mentioned instead of the habit, which takes its species from that act, because habit implies relation to act. And if anyone would reduce it to the proper form of a definition, he might say that "justice is a habit whereby a man renders to each one his due by a constant and perpetual will": and this is about the same definition as that given by the Philosopher (Ethic. v, 5) who says that "justice is a habit whereby a man is said to be capable of doing just actions in accordance with his choice."
Ad 1 Reply to Objection 1
Ad primum ergo dicendum quod voluntas hic nominat actum, non potentiam. Est autem consuetum quod apud auctores habitus per actus definiantur, sicut Augustinus dicit, super Ioan., quod fides est credere quod non vides.
Will here denotes the act, not the power: and it is customary among writers to define habits by their acts: thus Augustine says (Tract. in Joan. xl) that "faith is to believe what one sees not."
Ad 2 Reply to Objection 2
Ad secundum dicendum quod neque etiam iustitia est essentialiter rectitudo, sed causaliter tantum, est enim habitus secundum quem aliquis recte operatur et vult.
Justice is the same as rectitude, not essentially but causally; for it is a habit which rectifies the deed and the will.
Ad 3 Reply to Objection 3
Ad tertium dicendum quod voluntas potest dici perpetua dupliciter. Uno modo, ex parte ipsius actus, qui perpetuo durat. Et sic solius Dei voluntas est perpetua. Alio modo, ex parte obiecti, quia scilicet aliquis vult perpetuo facere aliquid. Et hoc requiritur ad rationem iustitiae. Non enim sufficit ad rationem iustitiae quod aliquis velit ad horam in aliquo negotio servare iustitiam, quia vix invenitur aliquis qui velit in omnibus iniuste agere, sed requiritur quod homo habeat voluntatem perpetuo et in omnibus iustitiam conservandi.
The will may be called perpetual in two ways. First on the part of the will's act which endures for ever, and thus God's will alone is perpetual. Secondly on the part of the subject, because, to wit, a man wills to do a certain thing always, and this is a necessary condition of justice. For it does not satisfy the conditions of justice that one wish to observe justice in some particular matter for the time being, because one could scarcely find a man willing to act unjustly in every case; and it is requisite that one should have the will to observe justice at all times and in all cases.
Ad 4 Reply to Objection 4
Ad quartum dicendum quod quia perpetuum non accipitur secundum durationem perpetuam actus voluntatis, non superflue additur constans, ut sicut per hoc quod dicitur perpetua voluntas designatur quod aliquis gerat in proposito perpetuo iustitiam conservandi, ita etiam per hoc quod dicitur constans designatur quod in hoc proposito firmiter perseveret.
Since "perpetual" does not imply perpetuity of the act of the will, it is not superfluous to add "constant": for while the "perpetual will" denotes the purpose of observing justice always, "constant" signifies a firm perseverance in this purpose.
Ad 5 Reply to Objection 5
Ad quintum dicendum quod iudex reddit quod suum est per modum imperantis et dirigentis, quia iudex est iustum animatum, et princeps est custos iusti, ut dicitur in V Ethic. Sed subditi reddunt quod suum est unicuique per modum executionis.
A judge renders to each one what belongs to him, by way of command and direction, because a judge is the "personification of justice," and "the sovereign is its guardian" (Ethic. v, 4). On the other hand, the subjects render to each one what belongs to him, by way of execution.
Ad 6 Reply to Objection 6
Ad sextum dicendum quod sicut in dilectione Dei includitur dilectio proximi, ut supra dictum est; ita etiam in hoc quod homo servit Deo includitur quod unicuique reddat quod debet.
Just as love of God includes love of our neighbor, as stated above (Q. 25, A. 1), so too the service of God includes rendering to each one his due.
