and immutable, the expression and command of Deity." In his treatise "De Legibus" he declared that men are born to justice; that right is established not by opinion but by nature; that all civil law is but the expression or application of this eternal law of nature; that the people or the prince may make laws but these have not the true character of law unless they be derived from the ultimate law; that the source and foundation of right law must be looked for in that supreme law which came into being ages before any state was formed.
This theory of the Stoics so eloquently urged by Cicero was practically the jus naturale of the Roman jurists of classical times, though more moderately expressed by them. It does not seem to have been wholly academic, but to have been actually applied at times. In his history of Rome, Mommsen relates that even during the nearly absolute sway of Sulla, after the fall of Marius, the Cornelian Laws enacted to deprive various Italian communities of their Roman franchise were ignored in judicial proceedings as null and void; also that, contrary to Sulla's decree, the jurists held that the franchise of citizenship was not forfeited by capture and sale into slavery during the civil war with Marius. Later, when the church became a power in the state there are instances where laws adjudged to be contrary to the laws of God were refused effect. In England as late as the middle of the 17th century Chief Justice Hobart, a judge of high repute, asserted that "even an act of Parliament made against natural equity, as to make a man judge in his own case, is void in itself for the laws of nature are immutable and they are the laws of laws." In the 18th century Blackstone assented to the doctrine of a jus naturale and wrote of it: "This law of nature being coeval with mankind and dictated by God himself is of course superior in obligation to any other… No human laws are of any validity if contrary to this, and such of them as are valid derive all their force and all their authority, mediately or immediately, from this original." True, Blackstone combated the doctrine that duly enacted statutes were to be held void if the judges thought them contrary to reason, but he admitted that that extreme doctrine was more generally held. In this country the doctrine of a higher law than the Constitution even, and to be obeyed rather than the Constitution and laws enacted in accordance therewith, has had and even now has earnest advocates.
But the contrary doctrine of Carneades and the Sophists would not down. After Cicero and the civilians, after Hobart and Blackstone, came our modern utilitarians, or sophists, Bentham, Mill, Austin, and others, who have vigorously maintained with weighty arguments the utilitarian theory of justice; and that theory is now generally accepted by lawyers and statesmen as at least the most workable theory in human affairs. There still exists, however, in the minds of many the belief that above and behind all the turmoil and strife of politics, all the flux and reflux of social movements and public sentiment, the confusion of enactments, amendments, and repeals of statutes, the swaying of judicial opinion, there is some law of nature or in nature, some criterion, which if ascertained and obeyed would be perfect justice.
This question of the origin, the foundation of justice, whether it be of God or of men, seems to have been much more debated than the question what is the nature of justice whatever its origin or foundation. Yet some attempts, other than those attributed to Socrates, have been made of old to give a definition of justice. The earliest description I have found is that of the early Pythagoreans, who, in accordance with their practise of symbolizing the virtues by geometrical figures, designated justice by the square, and the just man by the cube. Plato seems to have had a theory of justice when he wrote in the "Gorgias," "Nature herself intimates that it is just for the better to have more than the worse, the stronger than the weaker, and in many ways she shows that among men as well as among animals justice consists in the superior ruling over and having more than the inferior." In these days our first impulse may be to denounce Plato's statement as altogether wrong if not worse. We should remember, however, that Plato was not considering any altruistic virtue such as kindness, sympathy, benevolence, generosity and the like, but only what nature indicates to be the essential condition of successful association. Thus interpreted, are we prepared to confute the statement? Do we know of any state of society in human or animal life at any time, past or present, of which the contrary of Plato's statement is true?
But passing over all other attempts of the ancients to define justice, none of which seems to have been much regarded by contemporary opinion, I will only cite the most famous, that by Ulpian, the renowned jurist of the best period of Roman jurisprudence, whose writings were most drawn upon by the learned compilers of the Institutes and Digest of Justinian; viz., "Justitia est constans et perpetua voluntas jus suum cuique tribuendi," or "Justice is the constant and perpetual will to render to every one his right." This definition was adopted by the compilers as correct and made the introduction to the Institutes. It thus received the imperial sanction and was quoted wherever the law of Rome prevailed, down through medieval times and later, almost as if it were an inspired or at least authoritative definition not to be questioned. But notwithstanding the acclaim with which this definition was hailed, I question that it was any improvement on that of Aristotle, who tersely defined justice as "that virtue of the soul which is distributive according to desert." Indeed, I think Aristotle was nearer the mark.
Upon the revival of the study of law and jurisprudence in the 11th and 12th centuries several of the more famous jurists of that time, Azo, Irnerius, Placentinus and others, essayed definitions of justice, but they do not seem to have improved upon Ulpian. Their definitions were vitiated by theological assumptions and none of them has become a text for commentators or students. Neither in modern times has any definition of justice been suggested which has received such universal assent as did that of Ulpian in his time and for centuries afterward. We may therefore return to Ulpian's definition as our point of departure, since his definition is substantially that suggested earlier by Aristotle, and observations on the later will also apply in many respects to the earlier.
Ulpian's definition is elegant in style, but it does not carry us very far in our inquiry. We are told indeed that justice is a state or disposition of the mind, the disposition to render to everyone his right or, as put by Aristotle, is the disposition to distribute according to desert. It was this statement that captured the medieval jurists and which they made their text, but it is now regarded as incomplete and even inaccurate. One may have the disposition, the desire, the will, to render to every one his right, but unless he can know what is his fellow's right he may unwittingly fail to accord it to him and thus unwittingly do injustice. It evidently is not enough to have the disposition or will; hence the definition is incomplete, and any definition is incomplete which does not furnish a criterion for determining what is the given man's right.
But the definition as far as it does go is not strictly accurate. The man of malevolent disposition who would wrong his fellow if he dared, may yet, to avoid unpleasant consequences to himself, render fully to every other man his right. It would seem, therefore, that justice is an attribute or quality of conduct rather than a disposition or state of mind, and of conduct toward others rather than of conduct toward one's self. It is only of the conduct of men in their relations to other men that we can predicate justice or injustice. One's conduct may result in good or evil to himself and so be wise or unwise, but assuming, what probably is never the fact, that it affects only himself, in no way affects any other, his conduct is neither just nor unjust. Robinson Crusoe, until the arrival of the man Friday, had no occasion to consider our problem.
But, admitting that each man's conduct, whether active or passive, does affect some other person, what is the criterion by which to determine the justice or injustice of that conduct? It is not enough to say that if the conduct in any degree impedes the other person in the enjoyment of any of his rights it is unjust, otherwise not; for then the question comes to the front, what is the right of that other in the given case? Indeed, this latter question is the crux of the problem of justice. The derivation of the word "justice" also shows this. The Latin justitia or justitium according to some scholars is compounded of jus, right, and sisto or steti, to place, or to cause to stand, and hence the whole word may be held to signify the maintenance of jus or right. With the question of jus or right correctly answered, the problem of justice is practically solved. The right of the one being known, the effect of any particular conduct of another on that right, and consequently its justice or injustice, is determinable with
