Chapter 7

A like conclusion is suggested when we look into the related controversy as to the respective provinces of common law and of legislation. Inheritance and succession, definition of interests in property and the conveyance thereof, matters of commercial law and the creation, incidents and transfer of obligations have proved a fruitful field for legislation. In these cases the social interest in the general security is the controlling element. But where the questions are not of interests of substance but of the weighing of human conduct and passing upon its moral aspects, legislation has accomplished little. No codification of the law of torts has done more than provide a few significantly broad generalizations. On the other hand, succession to property is everywhere a matter of statute law and commercial law is codified or codifying throughout the world. Moreover the common law insists upon its doctrine of _stare decisis_ chiefly in the two cases of property and commercial law. Where legislation is effective, there also mechanical application is effective and desirable. Where legislation is ineffective, the same difficulties that prevent its satisfactory operation require us to leave a wide margin of discretion in application, as in the standard of the reasonable man in our law of negligence and the standard of the upright and diligent head of a family applied by the Roman law, and especially by the modern Roman law, to so many questions of fault, where the question is really one of good faith. All attempts to cut down this margin have proved futile. May we not conclude that in the part of the law which has to do immediately with conduct complete justice is not to be attained by the mechanical application of fixed rules? Is it not clear that in this part of the administration of justice the trained intuition and disciplined judgment of the judge must be our assurance that causes will be decided on principles of reason and not according to the chance dictates of caprice, and that a due balance will be maintained between the general security and the individual human life?

Philosophically the apportionment of the field between rule and discretion which is suggested by the use of rules and of standards respectively in modern law has its basis in the respective fields of intelligence and intuition. Bergson tells us that the former is more adapted to the inorganic, the latter more to life. Likewise rules, where we proceed mechanically, are more adapted to property and to business transactions, and standards; where we proceed upon intuitions, are more adapted to human conduct and to the conduct of enterprises. According to him, intelligence is characterized by "its power of grasping the general element in a situation and relating it to past situations," and this power involves loss of "that perfect mastery of a special situation in which instinct rules." In the law of property and in the law of commercial transactions it is precisely this general element and its relation to past situations that is decisive. The rule, mechanically applied, works by repetition and precludes individuality in results, which would threaten the security of acquisitions and the security of transactions. On the other hand, in the handmade, as distinguished from the machine-made product, the specialized skill of the workman gives us something infinitely more subtle than can be expressed in rules. In law some situations call for the product of hands, not of machines, for they involve not repetition, where the general elements are significant, but unique events, in which the special circumstances are significant. Every promissory note is like every other. Every fee simple is like every other. Every distribution of assets repeats the conditions that have recurred since the Statute of Distributions. But no two cases of negligence have been alike or ever will be alike. Where the call is for individuality in the product of the legal mill, we resort to standards. And the sacrifice of certainty in so doing is more apparent than actual. For the certainty attained by mechanical application of fixed rules to human conduct has always been illusory.

Liability

A systematist who would fit the living body of the law to his logical analytical scheme must proceed after the manner of Procrustes. Indeed, this is true of all science. In life phenomena are unique. The biologist of today sometimes doubts whether there are species and disclaims higher groups as more than conveniences of study. "Dividing lines," said a great American naturalist, "do not occur in nature except as accidents." Organization and system are logical constructions of the expounder rather than in the external world expounded. They are the means whereby we make our experience of that world intelligible and available. It is with no illusion, therefore, that I am leading you to a juristic _ultima Thule_ that I essay a bit of systematic legal science on a philosophical basis. Even if it never attains a final system in which the law shall stand fast forever, the continual juristic search for the more inclusive order, the continual juristic struggle for a simpler system that will better order and better reconcile the phenomena of the actual administration of justice, is no vain quest. Attempts to understand and to expound legal phenomena lead to generalizations which profoundly affect those phenomena, and criticism of those generalizations, in the light of the phenomena they seek to explain and to which they give rise, enables us to replace them or modify them or supplement them and thus to keep the law a growing instrument for achieving expanding human desires.

One of the stock questions of the science of law is the nature and system and philosophical basis of situations in which one may exact from another that he "give or do or furnish something" (to use the Roman formula) for the advantage of the former. The classical Roman lawyer, thinking in terms of natural law, spoke of a bond or relation of right and law between them whereby the one might justly and legally exact and the other was bound in justice and law to perform. In modern times, thinking, whether he knows it or not, in terms of natural rights and by derivation of legal rights, the analytical jurist speaks of rights _in personam_. The Anglo-American lawyer, thinking in terms of procedure, speaks of contracts and torts, using the former term in a wide sense. If pressed, he may refer certain enforceable claims to exact and duties of answering to the exaction to a Romanist category of quasi-contract, satisfied to say "quasi" because on analysis they do not comport with his theory of contract, and to say "contract" because procedurally they are enforced _ex contractu_. Pressed further, he may be willing to add "quasi tort" for cases of common-law liability without fault and workmen's compensation--"quasi" because there is no fault, "tort" because procedurally the liability is given effect _ex delicto_. But cases of duties enforceable either _ex contractu_ or _ex delicto_ at the option of the pleader and cases where the most astute pleader is hard pushed to choose have driven us to seek something better.

Obligation, the Roman term, meaning the relation of the parties to what the analytical jurists have called a right _in personam_ is an exotic in our law in that sense. Moreover the relation is not the significant thing for systematic purposes, as is shown by civilian tendencies in the phrases "active obligation" and "passive obligation" to extend the term from the relation to the capacity or claim to exact and duty to answer to the exaction. The phrase "right _in personam_" and its co-phrase "right _in rem_" are so misleading in their implications, as any teacher soon learns, that we may leave them to the textbooks of analytical jurisprudence. In this lecture, I shall use the simple word "liability" for the situation whereby one may exact legally and the other is legally subjected to the exaction. Using the word in that sense, I shall inquire into the philosophical basis of liability and the system of the law on that subject as related to that basis. Yellowplush said of spelling that every gentleman was entitled to his own. We have no authoritative institutional book of Anglo-American law, enacted by sovereign authority, and hence every teacher of law is entitled to his own terminology.

So far as the beginnings of law had theories, the first theory of liability was in terms of a duty to buy off the vengeance of him to whom an injury had been done whether by oneself or by something in one's power. The idea is put strikingly in the Anglo-Saxon legal proverb, "Buy spear from side or bear it," that is, buy off the feud or fight it out. One who does an injury or stands between an injured person and his vengeance, by protecting a kinsman, a child or a domestic animal that has wrought an injury, must compound for the injury or bear the vengeance of the injured. As the social interest in peace and order--the general security in its lowest terms--comes to be secured more effectively by regulation and ultimate putting down of the feud as a remedy, payment of composition becomes a duty rather than a privilege, or in the case of injuries by persons or things in one's power a duty alternative to a duty of surrendering the offending child or animal. The next step is to measure the composition not in terms of the vengeance to be bought off but in terms of the injury. A final step is to put it in terms of reparation. These steps are taken haltingly and merge into one another, so that we may hear of a "penalty of reparation." But the result is to turn composition for vengeance into reparation for injury. Thus recovery of a sum of money by way of penalty for a delict is the historical starting point of liability.

One's neighbor whom one had injured or who had been injured by those whom one harbored was not the only personality that might desire vengeance in a primitive society. One might affront the gods, and by one's impiety in so doing might imperil the general security, since the angered gods were not unlikely to hit out indiscriminately and to cast pestilence or hurl lightning upon just and unjust alike in the community which harbored the impious wrongdoer. Hence if, in making a promise, one called the gods to witness it was needful that politically organized society, taking over a field of social control exercised by the priesthood, give a legal remedy to the promisee lest he invoke the aid of the gods and jeopardize the general security. Again in making a promise one might call the people or the neighborhood to witness and might affront them by calling them to witness in vain. Here, too, the peace was threatened and politically organized society might give a remedy to the promisee, lest he invoke the help of his fellow citizens or his neighbors. A common case might be one where a composition was promised in this way for an injury not included in the detailed tariff of compositions that is the staple of ancient "codes." Another common case was where one who held another's property for some temporary purpose promised to return it. Such a case is lending; for before the days of coined money, the difference between lending a horse to go to the next town and lending ten sheep to enable the borrower to pay a composition is not perceptible. Thus another starting point of liability is recovery of a thing certain, or what was originally the same, a sum certain, promised in such wise as to endanger the general security if the promise is not carried out. In Roman law, the condiction, which is the type of actions _in personam_, and thus the starting point historically of rights _in personam_ and of theories of obligation, was at first a recovery of a thing certain or a sum certain due upon a promise of this sort. In juristic terms, the central idea of the beginnings of liability is duty to make composition for or otherwise avert wrath arising from the affronted dignity of some personality desirous of vengeance, whether an injured individual, a god or a politically organized society. Greek law and Roman law give the name of "insult" to legally cognizable injury to personality. Insult to a neighbor by injury to him or to one of his household, insult to the gods by impious breach of the promise they had witnessed, insult to the people by wanton disregard of the undertaking solemnly made in their presence, threatened the peace and order of society and called for legal remedy.

Lawyers begin to generalize and to frame conscious theories in the later part of the stage of the strict law. At first these theories are analytical rather than philosophical. The attempt is to frame general formulas by which the rigid rules of the strict law may be reconciled where they overlap or conflict or may be distinguished in their application where such overlapping or conflict threatens. By this time, the crude beginnings of liability in a duty to compound for insult or affront to man or gods or people, lest they be moved to vengeance, has developed into liability to answer for injuries caused by oneself or done by those persons or those things in one's power, and liability for certain promises made in solemn form. Thus the basis of liability has become twofold. It rests on the one hand upon duty to repair injury. It rests on the other hand upon duty to carry out formal undertakings. It is enough for this stage of legal development that all cases of liability may be referred to these two types and that useful distinctions may be reached therefrom. Consideration of why one should be held to repair injury, and why he should be held to formal undertakings, belongs to a later stage.

Juristic theory, beginning in the transition from the strict law to the stage of equity or natural law, becomes a force in the latter stage. As the relations with which the law must deal become more numerous and the situations calling for legal treatment become more complicated, it is no longer possible to have a simple, definite, detailed rule for every sort of case that can come before a tribunal, nor a fixed, absolute form for every legal transaction. Hence, under the leadership of philosophical jurists, men turn to logical development of the "nature" or ideal form of situations and to ethical ideas of what "good faith" or "good conscience" demands in particular relations or transactions. The strict law, relying on rule and form, took no account of intention as such. The words took effect quite independently of the thought behind them. But as lawyers began to reflect and to teach something more than a class or professional tradition, as they began to be influenced by philosophy to give over purely mechanical methods and to measure things by reason rather than by arbitrary will, emphasis shifted from form to substance; from the letter to the spirit and intent. The statute was thought of as but the lawmaker's formulation of a principle of natural law. It was not the _uerba_ that were efficacious, as in the strict law, which had inherited the primitive faith in the power of words and thought of the legal formula as if it were a formula of incantation possessing inherent magical force. It was the _ratio iuris_, which transcended words and formulas. So also the traditional rule was not a magic formula discovered by our fathers. It was a customary expression of a principle of natural law. Likewise the formal transaction was not a bit of private magic employed to conjure up legal liability. It was the clothing in legally recognized vestments of an intention to do what reason and good faith demand in a given situation. When form and intention concurred the promisor must answer for what he undertook. When the form used did not express or went beyond the intention or was the product of an apparent but not a real intention, the promisee was not to be enriched unjustly at the promisor's expense on the sole basis of the form. Moreover the duty was to be one of doing what good faith demanded, not one of doing literally and exactly what the letter of the undertaking called for. And although there was no express undertaking, there might be duties implied in the relation or situation or transaction, viewed as one of good faith, and one might be held to a standard of action because an upright and diligent man, who was his own master, would so act. Such is the mode of thinking in the classical period of the Roman law and it is closely paralleled by an independent development of juristic thought in the rise of equity and the absorption of the law merchant in our law.

It was easy to fit the two categories, delict and formal undertaking, which had come down from the strict law, into the new mode of thought. The typical delict required _dolus_--intentional aggression upon the personality or the substance of another. Indeed Aquilian _culpa_, in which the fault did not extend to intentional aggression, is a juristic equitable development. Hence when the legal was identified with the moral, and such identification is a prime characteristic of this stage, the significant thing in delict seemed to be the moral duty to repair an injury caused by wilful aggression. The legal precept was _alienum non laedere_. Also the duty to perform an intentional undertaking seemed to rest on the inherent moral quality of a promise that made it intrinsically binding on an upright man. The legal precept was _suum cuique tribuere_. Thus liability seemed to flow from intentional action--whether in the form of aggression or in the form of agreement. The "natural" sources of liability were delict and contract. Everything else was assimilated to one or the other of them. Liability without fault was quasi-delictal. Liability imposed by good faith to prevent unjust enrichment was quasi-contractual. The central idea had become one of the demands of good faith in view of intentional action.

In the nineteenth century the conception of liability as resting on intention was put in metaphysical rather than ethical form. Law was a realization of the idea of liberty, and existed to bring about the widest possible individual liberty. Liberty was the free will in action. Hence it was the business of the legal order to give the widest effect to the declared will and to impose no duties except in order to effectuate the will or to reconcile the will of one with the will of others by a universal law. What had been a positive, creative theory of developing liability on the basis of intention, became a negative, restraining, one might say pruning, theory of no liability except on the basis of intention. Liability could flow only from culpable conduct or from assumed duties. The abstract individual will was the central point in the theory of liability. If one was not actually culpable and yet established legal precepts which were not to be denied held him answerable, it was because he was "deemed" culpable, the historical legal liability being the proof of culpability. If he had not actually assumed a duty, and yet established legal precepts which were not to be denied held him to answer for it, this must be because he had assumed some relation or professed some calling in which an undertaking to that effect was "implied" or had participated in some situation in which it was "implied,"--the implication being a deduction from the liability. The bases of liability were culpable conduct and legal transaction, and these came down to an ultimate basis in will. The fundamental conception in legal liability was the conception of an act--of a manifestation of the will in the external world.

Roman law and English law begin with a set of what might be called nominate delicts or nominate torts. In Roman law there were _furtum_ (conversion), _rapina_ (forcible conversion) and _iniuria_ (wilful aggression upon personality). All these involved _dolus_, i.e. intentional aggression. The _lex Aquilia_ added _damnum iniuria datum_ (wrongful injury to property). Later there were added what might be called the equitable delicts of _dolus_ (fraud) and _metus_ (duress). Here also there was wilful aggression, and the delict of _dolus_ gets its name from the intentional misleading that characterizes it in Roman law as it does deceit in English law. In _damnum iniuria datum_, a wider conception of fault, as distinguished from intentional aggression, grew up by juristic development, and Aquilian _culpa_, that is, a fault causing injury to property and therefore actionable on the analogy of the _lex Aquilia_, furnished the model for the modern law. All these may be fitted to the will theory and modern systematic writers regularly do so. But noxal liability for injury done by a child or slave or domestic animal did not fit it, nor did the liability of a master of a ship, an innkeeper or a stable keeper to respond without regard to fault. Liability for injury done by child or slave or domestic animal was enforced in a noxal action on the analogy of the action which lay for the same injury if done by the defendant in person. Hence procedurally it seemed liability for a delict involving intentional aggression, and it was possible to say that there was fault in not restraining the agency that did the injury, although no fault had to be shown nor could absence of fault be shown as a defence. There was fault because there was liability, for all liability grew out of fault. Such treadings on the tail of its own argument are very common in legal reasoning. Likewise in the case of the absolute liability of the master of a ship, the innkeeper and the stable keeper, the institutional writers could say that they were at fault in not having proper servants, although here also fault need not be established by proof nor could want of fault be made a defence. As procedurally these liabilities arose in actions on the facts of particular cases, the jurists at first lumped them with many other forms of liability, which were not in fact dependent on intention and were enforced in actions _in factum_, as obligations arising from the special facts of cases (_obligationes ex uariis causarum figuris_). Later they were called quasi-delictual obligations and they are so designated in the fourfold classification of the Institutes. Buckland has remarked that in almost all of the liabilities included under quasi-delict in the Institutes there is liability at one's peril for the act of another, especially for one's servant, as in the noxal actions, the _actio de deiectis et diffusis_ (for things thrown or poured from buildings upon a way) and the _actio de recepto_ against an innkeeper. In other words, in these cases one was held without regard to fault for injuries incidental to the conduct of certain enterprises or callings and for failure to restrain potentially injurious agencies which one maintained.
