Articulus I
Whether Injustice Is a Special Virtue?
Arg. 1 Objection 1
Ad primum sic proceditur. Videtur quod iniustitia non sit vitium speciale. Dicitur enim I Ioan. III, omne peccatum est iniquitas. Sed iniquitas videtur idem esse quod iniustitia, quia iustitia est aequalitas quaedam, unde iniustitia idem videtur esse quod inaequalitas, sive iniquitas. Ergo iniustitia non est speciale peccatum.
It would seem that injustice is not a special vice. For it is written (1 John 3:4): "All sin is iniquity [Vulg.: 'Whosoever committeth sin, committeth also iniquity; and sin is iniquity']." Now iniquity would seem to be the same as injustice, because justice is a kind of equality, so that injustice is apparently the same as inequality or iniquity. Therefore injustice is not a special sin.
Arg. 2 Objection 2
Praeterea, nullum speciale peccatum opponitur omnibus virtutibus. Sed iniustitia opponitur omnibus virtutibus, nam quantum ad adulterium, opponitur castitati; quantum ad homicidium, opponitur mansuetudini; et sic de aliis. Ergo iniustitia non est speciale peccatum.
Further, no special sin is contrary to all the virtues. But injustice is contrary to all the virtues: for as regards adultery it is opposed to chastity, as regards murder it is opposed to meekness, and in like manner as regards the other sins. Therefore injustice is not a special sin.
Arg. 3 Objection 3
Praeterea, iniustitia iustitiae opponitur, quae in voluntate est. Sed omne peccatum est in voluntate, ut Augustinus dicit. Ergo iniustitia non est speciale peccatum.
Further, injustice is opposed to justice which is in the will. But every sin is in the will, as Augustine declares (De Duabus Anim. x). Therefore injustice is not a special sin.
Sed contra On the contrary
Sed contra, iniustitia iustitiae opponitur. Sed iustitia est specialis virtus. Ergo iniustitia est speciale vitium.
On the contrary, Injustice is contrary to justice. But justice is a special virtue. Therefore injustice is a special vice.
Respondeo I answer that
Respondeo dicendum quod iniustitia est duplex. Una quidem illegalis, quae opponitur legali iustitiae. Et haec quidem secundum essentiam est speciale vitium, inquantum respicit speciale obiectum, scilicet bonum commune, quod contemnit. Sed quantum ad intentionem est vitium generale, quia per contemptum boni communis potest homo ad omnia peccata deduci. Sicut etiam omnia vitia, inquantum repugnant bono communi, iniustitiae rationem habent, quasi ab iniustitia derivata, sicut et supra de iustitia dictum est. Alio modo dicitur iniustitia secundum inaequalitatem quandam ad alterum, prout scilicet homo vult habere plus de bonis, puta divitiis et honoribus; et minus de malis, puta laboribus et damnis. Et sic iniustitia habet materiam specialem, et est particulare vitium iustitiae particulari oppositum.
I answer that, Injustice is twofold. First there is illegal injustice which is opposed to legal justice: and this is essentially a special vice, in so far as it regards a special object, namely the common good which it contemns; and yet it is a general vice, as regards the intention, since contempt of the common good may lead to all kinds of sin. Thus too all vices, as being repugnant to the common good, have the character of injustice, as though they arose from injustice, in accord with what has been said above about justice (Q. 58, AA. 5, 6). Secondly we speak of injustice in reference to an inequality between one person and another, when one man wishes to have more goods, riches for example, or honors, and less evils, such as toil and losses, and thus injustice has a special matter and is a particular vice opposed to particular justice.
Ad 1 Reply to Objection 1
Ad primum ergo dicendum quod sicut iustitia legalis dicitur per comparationem ad bonum commune humanum, ita iustitia divina dicitur per comparationem ad bonum divinum, cui repugnat omne peccatum. Et secundum hoc omne peccatum dicitur iniquitas.
Even as legal justice is referred to human common good, so Divine justice is referred to the Divine good, to which all sin is repugnant, and in this sense all sin is said to be iniquity.
Ad 2 Reply to Objection 2
Ad secundum dicendum quod iniustitia etiam particularis opponitur indirecte omnibus virtutibus, inquantum scilicet exteriores etiam actus pertinent et ad iustitiam et ad alias virtutes morales, licet diversimode, sicut supra dictum est.
Even particular justice is indirectly opposed to all the virtues; in so far, to wit, as even external acts pertain both to justice and to the other moral virtues, although in different ways as stated above (Q. 58, A. 9, ad 2).
Ad 3 Reply to Objection 3
Ad tertium dicendum quod voluntas, sicut et ratio, se extendit ad materiam totam moralem, idest ad passiones et ad operationes exteriores quae sunt ad alterum. Sed iustitia perficit voluntatem solum secundum quod se extendit ad operationes quae sunt ad alterum. Et similiter iniustitia.
The will, like the reason, extends to all moral matters, i.e. passions and those external operations that relate to another person. On the other hand justice perfects the will solely in the point of its extending to operations that relate to another: and the same applies to injustice.
