The Path of the Law

by Oliver Wendell Holmes

This is not the time to work out a theory in detail, or to answer many obvious doubts and questions which are suggested by these general views. I know of none which are not easy to answer, but what I am trying to do now is only by a series of hints to throw some light on the narrow path of legal doctrine, and upon two pitfalls which, as it seems to me, lie perilously near to it. Of the first of these I have said enough. I hope that my illustrations have shown the danger, both to speculation and to practice, of confounding morality with law, and the trap which legal language lays for us on that side of our way. For my own part, I often doubt whether it would not be a gain if every word of moral significance could be banished from the law altogether, and other words adopted which should convey legal ideas uncolored by anything outside the law. We should lose the fossil records of a good deal of history and the majesty got from ethical associations, but by ridding ourselves of an unnecessary confusion we should gain very much in the clearness of our thought.

So much for the limits of the law. The next thing which I wish to consider is what are the forces which determine its content and its growth. You may assume, with Hobbes and Bentham and Austin, that all law emanates from the sovereign, even when the first human beings to enunciate it are the judges, or you may think that law is the voice of the Zeitgeist, or what you like. It is all one to my present purpose. Even if every decision required the sanction of an emperor with despotic power and a whimsical turn of mind, we should be interested none the less, still with a view to prediction, in discovering some order, some rational explanation, and some principle of growth for the rules which he laid down. In every system there are such explanations and principles to be found. It is with regard to them that a second fallacy comes in, which I think it important to expose.

The fallacy to which I refer is the notion that the only force at work in the development of the law is logic. In the broadest sense, indeed, that notion would be true. The postulate on which we think about the universe is that there is a fixed quantitative relation between every phenomenon and its antecedents and consequents. If there is such a thing as a phenomenon without these fixed quantitative relations, it is a miracle. It is outside the law of cause and effect, and as such transcends our power of thought, or at least is something to or from which we cannot reason. The condition of our thinking about the universe is that it is capable of being thought about rationally, or, in other words, that every part of it is effect and cause in the same sense in which those parts are with which we are most familiar. So in the broadest sense it is true that the law is a logical development, like everything else. The danger of which I speak is not the admission that the principles governing other phenomena also govern the law, but the notion that a given system, ours, for instance, can be worked out like mathematics from some general axioms of conduct. This is the natural error of the schools, but it is not confined to them. I once heard a very eminent judge say that he never let a decision go until he was absolutely sure that it was right. So judicial dissent often is blamed, as if it meant simply that one side or the other were not doing their sums right, and if they would take more trouble, agreement inevitably would come.

This mode of thinking is entirely natural. The training of lawyers is a training in logic. The processes of analogy, discrimination, and deduction are those in which they are most at home. The language of judicial decision is mainly the language of logic. And the logical method and form flatter that longing for certainty and for repose which is in every human mind. But certainty generally is illusion, and repose is not the destiny of man. Behind the logical form lies a judgment as to the relative worth and importance of competing legislative grounds, often an inarticulate and unconscious judgment, it is true, and yet the very root and nerve of the whole proceeding. You can give any conclusion a logical form. You always can imply a condition in a contract. But why do you imply it? It is because of some belief as to the practice of the community or of a class, or because of some opinion as to policy, or, in short, because of some attitude of yours upon a matter not capable of exact quantitative measurement, and therefore not capable of founding exact logical conclusions. Such matters really are battle grounds where the means do not exist for the determinations that shall be good for all time, and where the decision can do no more than embody the preference of a given body in a given time and place. We do not realize how large a part of our law is open to reconsideration upon a slight change in the habit of the public mind. No concrete proposition is self evident, no matter how ready we may be to accept it, not even Mr. Herbert Spencer's "Every man has a right to do what he wills, provided he interferes not with a like right on the part of his neighbors."

Why is a false and injurious statement privileged, if it is made honestly in giving information about a servant? It is because it has been thought more important that information should be given freely, than that a man should be protected from what under other circumstances would be an actionable wrong. Why is a man at liberty to set up a business which he knows will ruin his neighborhood? It is because the public good is supposed to be best subserved by free competition. Obviously such judgments of relative importance may vary in different times and places. Why does a judge instruct a jury that an employer is not liable to an employee for an injury received in the course of his employment unless he is negligent, and why do the jury generally find for the plaintiff if the case is allowed to go to them? It is because the traditional policy of our law is to confine liability to cases where a prudent man might have foreseen the injury, or at least the danger, while the inclination of a very large part of the community is to make certain classes of persons insure the safety of those with whom they deal. Since the last words were written, I have seen the requirement of such insurance put forth as part of the programme of one of the best known labor organizations. There is a concealed, half conscious battle on the question of legislative policy, and if any one thinks that it can be settled deductively, or once for all, I only can say that I think he is theoretically wrong, and that I am certain that his conclusion will not be accepted in practice semper ubique et ab omnibus.

Indeed, I think that even now our theory upon this matter is open to reconsideration, although I am not prepared to say how I should decide if a reconsideration were proposed. Our law of torts comes from the old days of isolated, ungeneralized wrongs, assaults, slanders, and the like, where the damages might be taken to lie where they fell by legal judgment. But the torts with which our courts are kept busy today are mainly the incidents of certain well known businesses. They are injuries to person or property by railroads, factories, and the like. The liability for them is estimated, and sooner or later goes into the price paid by the public. The public really pays the damages, and the question of liability, if pressed far enough, is really a question how far it is desirable that the public should insure the safety of one whose work it uses. It might be said that in such cases the chance of a jury finding for the defendant is merely a chance, once in a while rather arbitrarily interrupting the regular course of recovery, most likely in the case of an unusually conscientious plaintiff, and therefore better done away with. On the other hand, the economic value even of a life to the community can be estimated, and no recovery, it may be said, ought to go beyond that amount. It is conceivable that some day in certain cases we may find ourselves imitating, on a higher plane, the tariff for life and limb which we see in the Leges Barbarorum.

I think that the judges themselves have failed adequately to recognize their duty of weighing considerations of social advantage. The duty is inevitable, and the result of the often proclaimed judicial aversion to deal with such considerations is simply to leave the very ground and foundation of judgments inarticulate, and often unconscious, as I have said. When socialism first began to be talked about, the comfortable classes of the community were a good deal frightened. I suspect that this fear has influenced judicial action both here and in England, yet it is certain that it is not a conscious factor in the decisions to which I refer. I think that something similar has led people who no longer hope to control the legislatures to look to the courts as expounders of the constitutions, and that in some courts new principles have been discovered outside the bodies of those instruments, which may be generalized into acceptance of the economic doctrines which prevailed about fifty years ago, and a wholesale prohibition of what a tribunal of lawyers does not think about right. I cannot but believe that if the training of lawyers led them habitually to consider more definitely and explicitly the social advantage on which the rule they lay down must be justified, they sometimes would hesitate where now they are confident, and see that really they were taking sides upon debatable and often burning questions.

So much for the fallacy of logical form. Now let us consider the present condition of the law as a subject for study, and the ideal toward which it tends. We still are far from the point of view which I desire to see reached. No one has reached it or can reach it as yet. We are only at the beginning of a philosophical reaction, and of a reconsideration of the worth of doctrines which for the most part still are taken for granted without any deliberate, conscious, and systematic questioning of their grounds. The development of our law has gone on for nearly a thousand years, like the development of a plant, each generation taking the inevitable next step, mind, like matter, simply obeying a law of spontaneous growth. It is perfectly natural and right that it should have been so. Imitation is a necessity of human nature, as has been illustrated by a remarkable French writer, M. Tard, in an admirable book, Les Lois de l'Imitation. Most of the things we do, we do for no better reason than that our fathers have done them or that our neighbors do them, and the same is true of a larger part than we suspect of what we think. The reason is a good one, because our short life gives us no time for a better, but it is not the best. It does not follow, because we all are compelled to take on faith at second hand most of the rules on which we base our action and our thought, that each of us may not try to set some corner of his world in the order of reason, or that all of us collectively should not aspire to carry reason as far as it will go throughout the whole domain. In regard to the law, it is true, no doubt, that an evolutionist will hesitate to affirm universal validity for his social ideals, or for the principles which he thinks should be embodied in legislation. He is content if he can prove them best for here and now. He may be ready to admit that he knows nothing about an absolute best in the cosmos, and even that he knows next to nothing about a permanent best for men. Still it is true that a body of law is more rational and more civilized when every rule it contains is referred articulately and definitely to an end which it subserves, and when the grounds for desiring that end are stated or are ready to be stated in words.

At present, in very many cases, if we want to know why a rule of law has taken its particular shape, and more or less if we want to know why it exists at all, we go to tradition. We follow it into the Year Books, and perhaps beyond them to the customs of the Salian Franks, and somewhere in the past, in the German forests, in the needs of Norman kings, in the assumptions of a dominant class, in the absence of generalized ideas, we find out the practical motive for what now best is justified by the mere fact of its acceptance and that men are accustomed to it. The rational study of law is still to a large extent the study of history. History must be a part of the study, because without it we cannot know the precise scope of rules which it is our business to know. It is a part of the rational study, because it is the first step toward an enlightened scepticism, that is, towards a deliberate reconsideration of the worth of those rules. When you get the dragon out of his cave on to the plain and in the daylight, you can count his teeth and claws, and see just what is his strength. But to get him out is only the first step. The next is either to kill him, or to tame him and make him a useful animal. For the rational study of the law the blackletter man may be the man of the present, but the man of the future is the man of statistics and the master of economics. It is revolting to have no better reason for a rule of law than that so it was laid down in the time of Henry IV. It is still more revolting if the grounds upon which it was laid down have vanished long since, and the rule simply persists from blind imitation of the past. I am thinking of the technical rule as to trespass ab initio, as it is called, which I attempted to explain in a recent Massachusetts case.

Let me take an illustration, which can be stated in a few words, to show how the social end which is aimed at by a rule of law is obscured and only partially attained in consequence of the fact that the rule owes its form to a gradual historical development, instead of being reshaped as a whole, with conscious articulate reference to the end in view. We think it desirable to prevent one man's property being misappropriated by another, and so we make larceny a crime. The evil is the same whether the misappropriation is made by a man into whose hands the owner has put the property, or by one who wrongfully takes it away. But primitive law in its weakness did not get much beyond an effort to prevent violence, and very naturally made a wrongful taking, a trespass, part of its definition of the crime. In modern times the judges enlarged the definition a little by holding that, if the wrong-doer gets possession by a trick or device, the crime is committed. This really was giving up the requirement of trespass, and it would have been more logical, as well as truer to the present object of the law, to abandon the requirement altogether. That, however, would have seemed too bold, and was left to statute. Statutes were passed making embezzlement a crime. But the force of tradition caused the crime of embezzlement to be regarded as so far distinct from larceny that to this day, in some jurisdictions at least, a slip corner is kept open for thieves to contend, if indicted for larceny, that they should have been indicted for embezzlement, and if indicted for embezzlement, that they should have been indicted for larceny, and to escape on that ground.
