Of Right

Of Right — St. Thomas Aquinas asks: Whether right is the object of justice?; Whether right is fittingly divided into natural right and positive right?; Whether the right of nations is the same as the natural right?; Whether paternal right and right of dominion should be distinguished as special species?.

After considering prudence we must in due sequence consider justice, the consideration of which will be fourfold:

(1) Of justice;

(2) Of its parts;

(3) Of the corresponding gift;

(4) Of the precepts relating to justice.

Four points will have to be considered about justice: (1) Right; (2) Justice itself; (3) Injustice; (4) Judgment.

Under the first head there are four points of inquiry:

Article 1: Whether right is the object of justice?

Isidore says (Etym. v, 2) that "'jus' [right] is so called because it is just." Now the "just" is the object of justice, for the Philosopher declares (Ethic. v, 1) that "all are agreed in giving the name of justice to the habit which makes men capable of doing just actions."

It is proper to justice, as compared with the other virtues, to direct man in his relations with others: because it denotes a kind of equality, as its very name implies; indeed we are wont to say that things are adjusted when they are made equal, for equality is in reference of one thing to some other. On the other hand the other virtues perfect man in those matters only which befit him in relation to himself. Accordingly that which is right in the works of the other virtues, and to which the intention of the virtue tends as to its proper object, depends on its relation to the agent only, whereas the right in a work of justice, besides its relation to the agent, is set up by its relation to others. Because a man's work is said to be just when it is related to some other by way of some kind of equality, for instance the payment of the wage due for a service rendered. And so a thing is said to be just, as having the rectitude of justice, when it is the term of an act of justice, without taking into account the way in which it is done by the agent: whereas in the other virtues nothing is declared to be right unless it is done in a certain way by the agent. For this reason justice has its own special proper object over and above the other virtues, and this object is called the just, which is the same as "right." Hence it is evident that right is the object of justice.

Article 2: Whether right is fittingly divided into natural right and positive right?

The Philosopher says (Ethic. v, 7) that "political justice is partly natural and partly legal," i.e. established by law.

As stated above () the "right" or the "just" is a work that is adjusted to another person according to some kind of equality. Now a thing can be adjusted to a man in two ways: first by its very nature, as when a man gives so much that he may receive equal value in return, and this is called "natural right." In another way a thing is adjusted or commensurated to another person, by agreement, or by common consent, when, to wit, a man deems himself satisfied, if he receive so much. This can be done in two ways: first by private agreement, as that which is confirmed by an agreement between private individuals; secondly, by public agreement, as when the whole community agrees that something should be deemed as though it were adjusted and commensurated to another person, or when this is decreed by the prince who is placed over the people, and acts in its stead, and this is called "positive right."

Article 3: Whether the right of nations is the same as the natural right?

Isidore says (Etym. v, 4) that "right is either natural, or civil, or right of nations," and consequently the right of nations is distinct from natural right.

As stated above (), the natural right or just is that which by its very nature is adjusted to or commensurate with another person. Now this may happen in two ways; first, according as it is considered absolutely: thus a male by its very nature is commensurate with the female to beget offspring by her, and a parent is commensurate with the offspring to nourish it. Secondly a thing is naturally commensurate with another person, not according as it is considered absolutely, but according to something resultant from it, for instance the possession of property. For if a particular piece of land be considered absolutely, it contains no reason why it should belong to one man more than to another, but if it be considered in respect of its adaptability to cultivation, and the unmolested use of the land, it has a certain commensuration to be the property of one and not of another man, as the Philosopher shows (Polit. ii, 2).

Now it belongs not only to man but also to other animals to apprehend a thing absolutely: wherefore the right which we call natural, is common to us and other animals according to the first kind of commensuration. But the right of nations falls short of natural right in this sense, as the jurist [*Digest. i, 1; De Just. et Jure i] says because "the latter is common to all animals, while the former is common to men only." On the other hand to consider a thing by comparing it with what results from it, is proper to reason, wherefore this same is natural to man in respect of natural reason which dictates it. Hence the jurist Gaius says (Digest. i, 1; De Just. et Jure i, 9): "whatever natural reason decrees among all men, is observed by all equally, and is called the right of nations." This suffices for the Reply to the First Objection.

Article 4: Whether paternal right and right of dominion should be distinguished as special species?

The Philosopher (Ethic. v, 6) distinguishes right of dominion, paternal right and so on as species distinct from civil right.

Right or just depends on commensuration with another person. Now "another" has a twofold signification. First, it may denote something that is other simply, as that which is altogether distinct; as, for example, two men neither of whom is subject to the other, and both of whom are subjects of the ruler of the state; and between these according to the Philosopher (Ethic. v, 6) there is the "just" simply. Secondly a thing is said to be other from something else, not simply, but as belonging in some way to that something else: and in this way, as regards human affairs, a son belongs to his father, since he is part of him somewhat, as stated in Ethic. viii, 12, and a slave belongs to his master, because he is his instrument, as stated in Polit. i, 2 [*Cf. Ethic. viii, 11]. Hence a father is not compared to his son as to another simply, and so between them there is not the just simply, but a kind of just, called "paternal." In like manner neither is there the just simply, between master and servant, but that which is called "dominative." A wife, though she is something belonging to the husband, since she stands related to him as to her own body, as the Apostle declares (Eph. 5:28), is nevertheless more distinct from her husband, than a son from his father, or a slave from his master: for she is received into a kind of social life, that of matrimony, wherefore according to the Philosopher (Ethic. v, 6) there is more scope for justice between husband and wife than between father and son, or master and slave, because, as husband and wife have an immediate relation to the community of the household, as stated in Polit. i, 2,5, it follows that between them there is "domestic justice" rather than "civic."
