The following pages, which are the Appendix to a Treatise on Negligence which I am about to publish, have been bound in this detached shape, as a contribution to the controversy on Causation, which has been revived by Mr. Mill's Autobiography, and by Mr. Tyndall's Belfast Address. I have not undertaken, as will be seen, to do more than suggest one or two points bearing on the philosophical vindication of the view of causation held alike by theology and jurisprudence. My object is chiefly to show that the same objections which apply to theology in this respect apply to jurisprudence ; and if religion, because it holds to moral causation, is to be banished, as Mr. Tyndall announces, to the region of the " emotions," jurisprudence must share the same fate. Whether this fate is one of servitude or of supremacy will be presently seen. One other analogy I may be permitted to notice. It is said by the materialistic philosophers that even if there -be a God, the sequences of Nature are so fixed that He cannot intervene to grant prayer. Yet this objection to God's answering prayer applies with even greater force to a human government answering peti- tions to change the same sequences of Nature. "Look at this patch of soil," says the materialist ; " to produce verdure here, even as much as would arise from the diversion of a single drop of water, involves upsetting the equilibrium of the universe." But a* child does not disturb the equilibrium of the universe by bringing a cup of water from a hydrant to moisten this dry spot ; nor does a municipal government disturb this equilibrium by turning a river from its course and bringing it in pipes to the consumers' door. One of the commonest offices of Roman juris- prudence was the beneficent moulding of this power of bringing water in aqueducts from river to city ; one of the most important departments of our own jurisprudence is the supervision of our 3 PREFACE. municipal corporations when engaged in this work. Let us con- ceive that on a petition being presented to a court to compel a municipal corporation rightfully to execute a trust of this kind, an expert called by the defendant should content himself with testifying " that Nature produces all things spontaneously," and that Nature cannot be disturbed. Now such an expert, if per- sisting in such an answer, and declining to testify further, would be committed for contempt ; and the corporation, if it had no better defence, would be compelled by attachment to discharge its duty of supplying the water. The physicist might say that this is physical force compelling physical action ; and that this proves his theme. But if we inquire what it is that puts this physical force in motion, we find that it is the moral sense of the court ; and that of this moral sense one of the conditions is a recognition of the petitioners' claims, as thus solemnly presented, connected with the circumstance that the presentation of such a petition is a pledge of loyalty and of obedience, making a petition one of the proper preliminaries of the decree. If, however, the sponta- neousness of Nature, and the fixed physical laws which control matter, can be beneficently interrupted by the moral force of an earthly court, in response to a petition, a fortiori is such the case with the moral force exercised by a divine court which has unlimited power of compensating the disturbances caused by such interruption. And if an earthly court, in answer to a peti- tion, can compel water to flow through a city without disarrang- ing the universe, God, in answer to prayer, can send rain, Cambkidge, October, 1874. 4 APPENDIX, CAUSATION VIEWED JURIDICALLY. The doctrine advocated by Mr. J. S. Mill, that the cause of an event is the sum of all its antecedents, has been already summarily re- jected as irreconcilable with the principles both of Roman and of Anglo-American law. As the question, however, is one of first import- ance, I have thought it best to give to it, at this place, a more detailed examination. At the outset it may be observed that the classical Roman jurists, to whom I first appeal, form a line of authorities who cannot be lightly dismissed. They, at least, are not open to the charge of being either recluses, weaving, in their studies, schemes which cannot bear the strain of practical life, or enthusiastic devotees, dealing only with the spiritual relations of man to God, and not with those of man to man. The jur- ists whose opinions are collected in the Justinian Digest were eminently men of business, and the ethical as well as the juridical duties of the Roman Empire were moulded by them for the purposes of practical life. The result of their labor is a system of jurisprudence which, from the purity of the principles on which it rests and from its adaptation to the common needs of civilized society, is so admirable, so exact, so homely, and so philosophical, that it is in its leading features as applicable to the civilization of our own day, as it was to the civilization of Rome at her prime. " The Justinian Digest," so Gibbon substantially tells us, "is the most splendid monument of juridical genius that literature retains." " The Code of Justinian," so speaks Hallam, " will form the basis of all other systems, and mingling, as we may hope, with the new institutions of philosophic legislators, continue to influence the social relations of mankind long after its direct authority shall be abrogated. The ruins of ancient Rome supplied the materials of a new city, and the fragments of her law, which have been already wrought into the recent Codes of France and Prussia, will probably, under other names, guide far distant generations by the sagacity of Modestinus and Ulpian." " We look to the Roman jurists," says Sir Henry Maine, 1 in a passage which I quote 1 Middle Ages, vol. ii. ch. 9, pt. 2. 5 APPENDIX. from memory, " not only for what the law was, but for what it is to be." The opinion of these great, subtle, and at the same time eminently practical intellects, cannot be without weight on an issue on which the whole science of jurisprudence depends. Nor can it be said that these jurists spoke on this issue without being duly advised of its nature. The hypothesis of Mr. Mill, as Mr. Tyn- dall has lately reminded us, is as old as the first speculative philoso- phers. Cicero, who, though not himself claiming to be a jurist, dis- cusses, sometimes from a philosophical, sometimes from a rhetorical stand-point, the questions the jurists were called upon to decide, recurs not infrequently to the distinction between " causes " and " condi- tions " as fundamental to all sound jurisprudence. 1 A " condition " (or occasio), so he tells us, is a mechanical antecedent without causal power; a cause is the responsible voluntary agent changing the ordinary course of nature. 2 So, as Flavel reminds us, " critical and exact historians, as Polybius and Tacitus, distinguish betwixt the apxn and the atria, the beginning occasions, and the real causes of a war." 3 A distinction so universally recognized must have been familiar to the great classical jurists whose duty it was to determine liability for causation. Even Lucretius, fantastic as he was, could not have been unknown to the later jurists of whom he was the contemporary ; and when Lucretius declared in words with which Mr. Tyndall tells us there is so great a temptation now to close, that " Nature is seen to do all things sponta- neously," no doubt this opinion, if it had been thought of any weight, would have been noticed in those discussions in which questions of causation were settled. If, however, the conjectures of the material- istic philosophers were ever criticised by the great and grave think- ers whose decisions the Pandects preserve, it was probably with some such curt sentence as the following recorded by Cicero : " Nihil tam absurde dici potest quod non dicatur ab aliquo philosophorum." 4 Philosophical discussions on such elementary questions it was not in 1 See this in his essay defato, where noticed by Ueberweg, in his History he discusses the views of Democritus of Philosophy, vol.

Though endowed with the subtlest and at the same time most vigorous mental gifts ; though conversant as a prerequisite to their office, with the philosophy of the schools, their business was, not to reopen the foundations of jurisprudence, but to apply its principles both philosophically and exactly to the business questions of the day. Hence we do not find in the opinions of the jurists any discussion of the distinction between " conditions " and " causes," or any expanded vindication of the principle that nothing that is not a free agent can be viewed as a " cause." But while the convertibility of causality with free agency is not discussed, it is everywhere presup- posed. Hundreds of cases are given in the Digest in which the ques- tion is involved ; and in each case, with a dry authoritativeness which shows that the truth of this position is regarded as fundamental, the office of the jurist is to cast out of the issue all "antecedents " that are not free agents, and then to determine which among these free agents was the immediate cause. Among these cases I now select two as illus- trations. A fire is sweeping over the dry grass of a terrace which is crowned by a villa. 1 The villa is consumed. The fire, it appears, originated in a distant field, where it was started for legitimate farming purposes. What is the juridical cause of the burning of the villa ? In other words, what is the cause of the communication to this villa of the fire from the remote spot where it was first kindled? The jurist, in answering this question, betakes himself immediately to distinguishing between the " conditions " and the " cause " of the conflagration ; in other words, between such antecedents as were inevitable, and hence to be treated as casus, and such as could have been avoided by due care on the part of those watching the fire. Physical science, indeed, is invoked to aid in the inquiry ; but it is invoked simply as a collector of testimony whose weight and meaning jurisprudence is to determine. " Was the wind blowing at the time in such a way as to make it negligent then to start a fire ? " " Were the conditions of the atmosphere, on that hot autumn day such as to make any fire on those dry fields dangerous ? " Physical science is employed to search for materials, and even to suggest hypoth- eses, bearing on these questions ; but when it has done this its office is complete. It does not, even if its experts can agree upon a conclusion, decide. Willing or unwilling, it is required to discriminate between the <* antecedents " of the fire, and to give, in tones harmonious or conflict- ing as the case may be, its report as to which of these antecedents are attributable to human intervention, and which are not. Undoubtedly much aid can thus be received by jurisprudence. But this aid is simply that which an expert witness offers to a judge. Lucretius may be the 1 See L. 30. § 3. D. de Leg. Aq. commented on supra, § 116, 865. 7 APPENDIX. witness. Lucretius may, in his testimony, say that all things are spon- taneous ; yet even Lucretius will be compelled to answer the question as to which of these antecedents were beyond, and which within, the con- trol of those watching the fire. And no matter what may be the opinion of Lucretius, the jurist decides the question upon the principle that if those watching the fire could have extinguished it when danger was probable, but omitted so to extinguish it, then they are liable for burn- ing the villa. So as to the question which comes up when a building falls in, and when the jurist has to decide whether the disaster is caused by negli- gence. This question appears frequently to have arisen, and no wonder, when we contrast the ponderous grandeur of Roman architecture with the risks of inundation at one place from lava torrents, at another from Apennine floods, as well as from the assiduis pluviis of which the jurist in the case before us, speaks. To what is the sinking of the walls traceable ? Specialists are to be found in this department as au- thoritative as any who *have ranked among the great masters of archi- tecture. Are they to be interrogated as to whether or no the falling of the wall is owing to causes that were unavoidable ? Far from this. No doubt architects are summoned to state whether the wall was carefully laid. But when the question of causation arises, then the opinion of these experts is not asked. For, even supposing they should agree as to what caused the particular result (and agreement among experts appears to have been as rare in Roman courts as it is in our own), physicists who treat all antecedents as causes, and who can only judge of material forces, can afford no aid to jurisprudence when it undertakes to distinguish those conditions which are material, and therefore merely consecutive, from those which are moral and causal. The physicist may say, "All these antecedents are causes." The jurist takes up each antecedent in turn, and casting out of account all antecedents which are not the result of the immediate action of a free agent, says that the latter alone constitute a cause, and the latter alone can be held liable as such. If the building fell by such a series of unprecedented rains as ordinary prudence could not have guarded against, then there is no cause which jurisprudence holds liable. If, however, the falling in of the wall was immediately occasioned by the negligent excavation of the builder of a neighboring house, then such builder is the juridical cause. 1 In Anglo-American jurisprudence we have the same result, if not as advisedly, at least as summarily reached as in the Roman. Of this we may take as an illustration the first leading English case in which the 1 L. 57. D. loc. 19. 2. cited supra, § 115. CAUSATION VIEWED JURIDICALLY, question of causation was distinctively discussed. 1 A., at a fair, as a sort of coarse joke, threw a squib into a market-house. The squib fell upon the table of B., who convulsively and mechanically, to prevent it hurting the goods on the table, tossed it off, when it fell on the table of C. C, in the same way, also to prevent an explosion on his table, threw the squib instantaneously off, when it struck D. in the face, and on the concussion exploded, injuring D. in the eye. What was the cause of D.'s hurt ? Now here is a question as to which physical as well as mental philoso- phers might well be consulted, for it involves not only the fundamental doctrines of causation, but the distinction, if there be such, between such human actions as are necessitated, and such as are free. We can conceive therefore, of Mill, or of Hume, or of Lucretius, being summoned on such a question ; and we can anticipate what would be their reply. " A., B., and C. were all antecedents : A., B. and C. were all causes. This is enough." But it is not enough. If B. and C. acted convulsively and mechanically in what they did, then they were not free agents, and therefore not causes. If A. acted negligently or mischiev- ously, and set in motion the agency of B. and C. who acted only mechan- ically, then he was the cause of the disaster. To make a " cause " it is essential that there should be free agency. So substantially decide the judges in Scott v. Shepherd ; and this decision is in full accordance with that of the Roman jurists. If we deny causal power to human beings acting mechanically, a fortiori must we deny causal power to matter. That such is the conclusion of Anglo-American law is sus- tained by a vast net-work of cases, which are presented in the pre- ceding pages, and which, however they may differ in detail, unite in assuming that only a free moral agent can be a cause. Unphilosophical no doubt may have been some of the judges who have thus ruled, if to philosophy it is essential that the primary principles of ethics and of jurisprudence should be reopened at every argument. Devoted most of these judges no doubt were to the traditions of the law. But whatever may have been their demerit they do not deserve the charge so often made against the advocate of the supremacy of moral forces over phys- ical, of being mere closet theorists. There is no class of men more observant of human nature, more considerate in the adaptation of fixed principles to that nature as it exists, and yet at the same time more conscientious both in ethical statement and logical application, than the judges of England and of the United States. To say that they are not philosophers is far less to their discredit than to the dis- 1 Scott v. Shepherd, 1 W. Bl. 892 ; 1 Smith's Leading Cases, 549 ; 7th Am. ed. 755 ; supra, § 95. 9 APPENDIX. credit of the philosophy which they ignore. If the materialistic view of causation, even with the high indorsement it has received from Hume and Mill, has not, with rare exceptions, been considered, by Anglo- American courts, to call even for discussion, this shows that so far as concerns practical life, the materialistic view of causation has no ground on which to stand. We might, therefore, in discussing the question of causation, content ourselves with taking the unbroken opinion of those eminent expositors both of Roman and Anglo-American law who have made the question of responsibility for causation their especial study, and whom the state has from time to time charged with the duty of de- fining and enforcing this responsibility. Waiving for a moment, how- ever, this authority, I beg leave to suggest in addition the following reasons for rejecting the materialistic scheme of causation. 1. If all the antecedents are the cause of any given effect, then, as all the antecedents existing at a particular time are the same, all the effects after that time must be the same. It may be replied that each effect has its specific conditions. But as those conditions exist (as an- tecedents) prior to their effects, and as on this hypothesis as well from the necessary interdependence of all objects in place, they form a united body of phenomena, then all events occurring at one time over all space, being the effect of the same cause, would be the same. If we assume that the same causes produce different effects, this at once destroys the assumption that the same causes necessarily produce the same effects. If we assume that one effect has a distinguishing ante- cedent which precedes no other effect under the same conditions, then we have an antecedent which is not an antecedent. If it be answered, as is sometimes the case, that each effect is qualified by an antecedent evoked by its own distinctive type, then we have an effect which is its own cause. 2. Next may be noticed the practical communism which this theory of the causal character of all antecedents promotes. " Here is a cap- italist among these antecedents ; he shall be forced to pay." The cap- italist, therefore, becomes liable for all disasters of which he is in any sense the condition, and the fact that he thus is held liable, multi- plies these disasters. Men become prudent and diligent by the con- sciousness that they will be made to suffer if they are not prudent and diligent. If they know that they will not be made to suffer for their neglects ; if they know that though the true cause of a disaster, they will be passed over in order to reach the capitalist who is a remoter condi- tion, then they will cease to be prudent. The privileged classes of feud- alism were dissolute and reckless because they could not be made to pay for injuries they inflicted. The non-capitalists, who on this theory 10 CAUSATION VIEWED JURIDICALLY. of the causal character of all antecedents, will be the privileged classes of our own times, will become dissolute and reckless, because they, be- ing non-responsible in a pecuniary seuse, will not be called upon to pay for the injuries they inflict. In one sense this would cure itself, because the distinction between capitalist and non-capitalist would soon cease. If capital is not destroyed in such an encounter, it would decline to ex- pose itself to such risks. No engineer would peer into regions which, rich as they may be, are fraught with perils in proportion to their riches. No factory would be built, for factories, though productive of wealth, have in them wheels against which incautious visitors might run, and require the use of steam or water power which reckless tres- passers might abuse. Making the capitalist liable for everything, there- fore, would end in making the capitalist, as well as the non-capitalist, liable for nothing ; for there would be soon no capitalist to be found to be sued. 1 3. This levelling of all antecedents to the same parity, in denying man's moral primacy over and responsibility for nature, destroys the true mission of that physical science in whose supposed interest the materi- alistic philosophy of causation is advanced. The mission of physical science is that of the exploration and direction of physical forces ; the mission of jurisprudence, viewing the term in its broad sense, is that of distinguishing between physical and moral forces, and of requiring that physical forces be directed in conformity with moral law. When physical science departs from this service, its speculations are as value- less as are the houses built by a child on the sand. And even when it undertakes the office of determining what is and what is not the re- sult of responsible causation, it acts in subordination to jurisprudence. It merely reports the facts; jurisprudence, so far as concerns the law of the land, not only compels it to make the report, but decides ulti- mately what the report means. It is true that there is something at the first view humiliating to physical science to be thus assigned to a subordinate sphere. An em- inent physicist, to view the question in the concrete, is placed on the witness stand and asked as to the cause of a particular disaster. He answers that the cause "is the sum of all the antecedents," or that "nature spontaneously acts without moral intervention." He is told, however, by the judge that the answer is frivolous ; and he is compelled, on pain of imprisonment for contempt, to repudiate his whole philoso- phy, and to discriminate between such antecedents as are produced by responsible volition, and such as are not so produced. His duty, he is told, is to collect facts, not to determine their moral bearings ; to make 1 See this argued more fully, supra, § 145-9. 11 APPENDIX. discoveries, if he can, and to direct the forces he discovers, if he can, but to do this only in subordination to moral law. He may revolt at being thus treated as a mere hewer of wood and drawer of water for jurisprudence, and he may be tempted to exclaim, with Caliban, — " A plague upon the tyrant that I serve, I'll bear him no more sticks." " I say, by sorcery he got this isle, From me he got it." But the " sorcery " is simply that which moral power, as a necessity of their common natures, exercises over physical. This supremacy, so far as concerns the topic immediately before us, has not been arbitrarily imposed. Jurisprudence has done her best to secure the services of physical and psychological science in the determination of issues in which physical and psychological incidents are involved. Experts have been cordially welcomed for this purpose, and when it was found that in all questions involving moral considerations such experts were hope- lessly distracted ; when it was found that no paradox was so startling but that some expert advanced to sanction it by his oath ; 1 when it was found that even as to matters purely physical the number of experts testifying on the one side was usually equal to the number of experts testifying on the other side, 2 practical jurists endeavored to devise 1 Thus we have cases in which materialistic physicians have sworn to the irresistibility of impulse ; and other cases in which, after swearing that certain facts showed insanity, witnesses have said on cross-exami- nation that all great crimes presuppose insanity, and that no suicide is sane. So " dipsomania " has been declared to be a specific form of insanity, con- ferring irresponsibility; and so, gen- erally, as to " moral insanity." See this fully illustrated in 1 Whart. & Stil. Med. Jur. § 196 et seq. 2 In issues of insanity this equipoise is proverbial. There is scarcely a case in which insanity is set up in which philosophers of the materialistic school are not summoned to prove the non- responsibility of particular manias; and the best that the prosecution can gen- erally do is to give the case to the fused. Nor is it in insanity cases only that this condition exists. On the trial of Mrs. E. G. Wharton, in Maryland, in 1872, the questions whether poison was discovered in the remains of the deceased, and whether the deceased's symptoms were those of poisoning, divided the eminent ex- perts who were examined into two hostile schools. On the trial of Stokes, in New York, in the same year, for the murder of Fisk, one half of the surgical experts swore that the mor- tal wound oame from Stokes, and the other half swore that it came from the surgeons who undertook to cure Fisk. On the first trial of Dr. Schoeppe, in Pennsylvania, in the same year, for poisoning, the court determined to ac- cept the conclusions of the single ex- pert examined for the prosecution ; but after conviction it was found that jury with the observation that the this expert had been governed by rules expert testimony is hopelessly con- that one half of his profession had dis- 12 CAUSATION VIEWED JURIDICALLY. some new mode by which expert opinion could be brought out more satisfactorily than by examination on trial. In Germany several such schemes have been attempted, but without success. 1 In England and in the United States the ingenuity of legislators has been unavailingly tasked for the same purpose. No plan has as yet been suggested by which physical science can be enabled to pronounce moral judgments satisfactory even to itself; and jurisprudence has reluctantly reached the conclusion that physical science has and can have no capacity to form such judgments, and that its representatives, able, experienced, and honored as they are, must be confined, when examined in a court of justice, to a mere statement of facts, and must be forbidden, when on the witness stand, to express any moral or legal conclusion from such facts. 2 And this prohibition, let it be again noticed, is reluctantly is- sued. It springs from no jealousy, for nowhere are the true claims of physical science more honored than in courts of law. 3 But the prohi- bition has arisen from the failure of all efforts to make physical science speak coherently on any issue involving the moral relations of physical facts. And the reason is that to physical science the sceptre of govern- ment is, by the nature of things, denied. If a railroad operator, for carded, and a new trial had to be granted. As to blood stains, in no trial where the question comes up are we spared the spectacle of experts affirming, and then of experts denying the human quality of the blood. 1 This is fully shown by Liman, in the 5th ed. of Casper's Gericht. Med. 2 In England this is ruled in ?,. v. Richards, 1 F. & F. 87; R. v. Higgin- son, 1 C. & K. 129. Among the Amer- ican cases where the same point is decided may be mentioned State v.

Dewey, 107 Mass. 494 ; Cook v. State, 4 Zab. 843. 8 Thus it was in no unkind feeling, but the necessities of his position, which led Chief Justice Chapman, of Massachusetts, in charging, in 1868, in a homicide case in which a peculiarly wild defence had been sworn to by experts, to say that, " I think the opinions of experts are not so highly regarded now as they were ; for, while they often afford a great aid in determining facts, it often happens that experts can be found to tes- tify to any theory, however absurd.' * Andrews's Trial, p. 356. Judge Davis, of the supreme court of Maine, in a similar emergency, when pressed by a mass of expert testimony denying responsibility, was forced to declare : "If there is any kind of testimony that is not only of no value, but even worse than that, it is, in my judgment, that of medical experts ; " and this censure is substantially indorsed by Judge Redfield. Neal's case, cited 1 Redfield on Wills, ch. III. § 13. The proposition of the lord chancellor, after the extraordinary expert testi- mony in the Windham case, that experts should only be permitted to testify as to facts within their own observation, is an illustration of the same judicial tendency. 13 APPENDIX. instance, runs his road carelessly, and injury to others results, he may either be indicted for the negligence, or a suit may be instituted against him for damages. In the first case, the person of the " physicist " is seized and put in prison ; in the second, his property may be taken from him by the sheriff. He may say that this is simply physical force acting on physical force ; and that this only confirms his theory of causation, and of the supremacy of physical force. No doubt the sheriff acts phys- ically ; but what forces the sheriff to act ? Physical force, it may be again said ; for otherwise the sheriff would himself be sent to prison. But what puts this process against the sheriff in motion ? Ultimately we must fall back upon the conscience of the judge ; upon the moral sense of the community, requiring that municipal law should be obeyed; upon the public conviction that this obedience is required by the good of society and by the will of God. And to this moral force physical force must be subordinate, and from its incapacity of moral adjudication must confess its subordination. Yet it is to this subordination of physical to moral force that physical science owes its true glory. It has won no victories in any campaigns in which it has not thus served. As the servant of moral and juridical law its discoveries have been at once brilliant, beneficent, and secure. To the shelter of law it has owed its opportunities for studious exploration. To the patents granted by law it owes the enjoyment of the fruits of such discoveries. To the severe axiom of law, that care in the exercise of material forces must be in proportion to the greatness and peril of such forces, does it owe those qualities of delicate and subtle modification and compensation by which the powerful agencies discovered by the physicist may by the physicist be made beneficial to mankind. There have un- doubtedly been periods when physical science has thrown off this yoke, and when the physicist has appeared to the vulgar eye as a diviner ; but these have been the most inglorious eras of scientific history, — the eras when astronomy was lost in astrology, and chemistry in alchemy, open and responsible science in occult charlatanry. The true con- quests of physical science have been achieved under this very system of the subordination of the physical to the moral. If genius, inde- pendently of this system, has made great discoveries, it has only been through this system that these discoveries have been so moulded and guarded as truly to benefit and elevate mankind. Under other systems physical science may be sometimes worshipped with ignorant and super- stitious awe. It shines with its true splendor and wins its just applause only where moral force is supreme. 14 LIBRARY OF CONGRESS I* 029 779 804 2 LIBRARY OF CONGRESS mil inn 1 1 mi in I Hill I 1 III II Hill 029 779 804 2 LIBRARY OF CONGRESS 029 779 804 2 •
