THE EXPANSION OF THE COMMON LAW.
IV 'THE LAW OF REASON.'
A. THE LAW OF NATURE AND OF NATIONS.-—If there is one virtue that our books of authority claim for the Common Law more positively than another, it is that of being
reasonable. The law is even said to be the perfection of
reason. Not that the meaning of that saying is exhausted
by the construction which a layman would naturally put
upon it. For, as Coke had to tell King James I much to
his displeasure, there is an artificial reason of the law. Certainty is among the first objects of systematic justice.
General principles being once fixed, the only way to attain
certainty is to work out and accept their consequences unless there is some very strong reason to the contrary. In
hundreds of cases it is possible to suggest several rules of
which, at first sight, any one would serve as well as another;
and if we are asked why we have chosen one and rejected
the others, the answer is that the one we have preferred is
deducible from our larger established principles, or at least
consistent with and analogous to them, and the others
-are not. It is not good to choke rules with exceptions
merely for the sake of some small apparent convenience in
the result, and at the risk of finding later that the excep-
tion, if not qualified by a second order of exceptions, is on
the whole less just than the rule. The sound method, as
Parke laid down in an opinion given to the House of Lords
seventy years ago, is to apply the settled rules of the law,
where the application is not plainly unreasonable or inconvenient, to all cases which arise. But this very dictum
assumes the existence, besides the reason which guides us
in fixing the letter of the law, of a larger reason which
informs the spirit of the law and must, in the last resort, be
the justification of the controlling rules themselves. Of
this primary reason, too, not only book-learning but every
day’s practice has much to tell us. Reasonable price and

reasonable time are among the most familiar elements in
our law of contract. Oftentimes no more definite instruction can be given to a jury than to award reasonable dam-ages. “Natural reason and the just construction of the
law,” as Blackstone said, have given us the various applications of the common counts, extending to the whole field of
what we now call Quasi-contract. In Lord Mansfield’s hands
the principles of natural equity were an enchanter’s wand to
call a whole new world of justice into being. The test of
what a reasonable man’s conduct would be in the circumstances governs our modern law of negligence and underlies those branches of it which have been specialized into
groups of definite rules. Almost in our own time a simple
and wholly untechnical conception of the same kind has
been developed into the doctrine of estoppel “in pais,”
perhaps the most powerful and flexible instrument to be
found in any system of civil jurisprudence. The scientific
importance of this external standard of reasonableness,
which enables the law to keep in close touch with the moral
and practical sense of mankind in the affairs of life, was
demonstrated once for all, more than twenty years ago, by
my friend Mr. Justice Holmes; and if my own endeavours
to pursue its application in detail have any value, it is
largely due to his example.
What is the origin, and what are the doctrinal affinities,
of this pervading ideal, of which it would be hardly too
much to say that it is the life of the modern Common Law?
It may seem paradoxical to answer that we owe it to the
Greeks; and yet it goes near to be true. Christopher St.
German, the very able and learned author of the “Doctor
and Student,” touched the right clue early in the sixteenth
century. The Student of the laws of England, being asked
by the Doctor of Divinity what he has to say of the Law of
Nature, makes answer that among common lawyers the
term is not in use, but they speak of reason Where a canon-
ist or civilian would speak of the Law of Nature. “It is
not used among them that be learned in the laws of England to reason what thing is commanded or prohibited by
the Law of Nature, and what not, but all the reasoning in
that behalf is under this manner.~ As when anything is
THE EXPANSION OF THE COMMON LAW 173
grounded upon the Law of Nature, they say that Reason
will that such a thing be done; and if it be prohibited
by the Law of Nature, they say it is against Reason, or that
Reason will not suffer that to be done.”’ It is curious that
this passage should have been, so far as I know, completely
overrooked; but the medieval tradition of the Law of Nature
was broken up by the controversies of the Reformation,
and seventeenth-century writers are quite confused about
it. This however does not alter the reality of the parallel
as it stood in the sixteenth century, nor diminish the prob-
ability of a real connexion with the scholastic doctrine,
which was as much philosophical and political as legal.
That doctrine rested partly on the ~Aristotelian distinction
between natural and conventional justice, partly on the
Latin expositions by Cicero and others of the same distinction as developed by the later Greek schools, and partly cm
the technical adaptation of it by the classical Roman jurists,
who identified lex naturalis or ius naturale with the ius gentium of the Pr~torian law, subject to one or two theoretical
exceptions which we have not to consider here. Directly
or indirectly, therefore, the Law of Nature, as accepted
throughout the Middle Ages, was derived from Greek
theories of ethics.2
Now the term ius naturce, not in use among English
lawyers in St. German’s time, does occur in our books,
though not frequently, from the seventeenth to the nineteenth century, and we have a recent judicial interpretation
of it. “The foundation of the right” [to watercoursesi,
says Farwell J., “as stated throughout all the cases is jus
naturae * * * I have come to the conclusion that jus
naturae is used in these cases as expressing that principle
in English law which is akin to, if not derived from, the jus
naturale of Roman law. English law is, of course, quite in-
dependent of Roman law, but the conception of aequum et
bonum and the rights flowing therefrom which are included
in jus naturale underlie a great part of English common
law; although it is not usual to find ‘the law of nature’
or ‘natural law’ referred to in so many words in English
cases * * * I am not, therefore, introducing any novel

principle if I regard jus naturne, on which the right to running water rests, as meaning that which is aequum et
bonum between the upper and lower proprietors.” 1 The
Roman conception involved in “aequum. et bonum” or
“aequitas” is identical with what ‘ye mean by” reasonable,”
or very nearly so. Such has been the result obtained, in
modern times, by the application of historical scholarship to
the Roman authorities on their own ground. On the whole
the natural justice or “reason of the thing” which the
Common Law recognizes and applies does not appear to
differ from the law of nature which the Romans identified
with ius gentiuni, and the medieval doctors of canon and
civil law boldly adopted as being divine law revealed
through man’s natural reason. I do not assume that our
Germanic customary law, set free from the fetters of its
original archaic procedure, was not capable of striking out
an equivalent guiding principle for itself. But we have
to remember that the whole of medieval thought was
pervaded by a craving for authority, or at least a plausible
show of it. Best of all was the text of Scripture, whether
taken in the natural sense or not. Aristotle was next best.
Cicero was very well. Ovid, or Virgil, or almost any
Roman author, was well enough in the absence of any more
oommanding name. Is it too fanciful to connect this habit
of mind with the deeply rooted Germanic custom of vouch-
ing a warrantor? I know not; but it is certain that the
medieval author who had nobody to vouch appeared to his
contemporaries either to display indecent arrogance or to
confess discreditable ignorance. In the present case the
Law of Nature was there; not merely a doctrine or rule of
the imperial law, to which English lawyers could not be
openly beholden, but a principle sanctioned by the Church
as fundamental and paramount. The Roman lawyers, in
search of a rational sanction for the authority of the ius
gentiunz, had gone to the Greek philosophy of natural
justice; the medieval publicists, twelve centuries later,
found in their revived learning this fabric of natural reason
claiming respect by the triple authority of Aristotle, Cicero,
and the Corpus Juris; this last, be it observed, being no

THE EXPANSION OF THE COMMON LAW 175
pagan document, but the legislation of the orthodox em-
peror Justinian. Evidently the Law of Nature must have
its place in the Christian system of Church and State, and
no mean place. The problem was solved in the Decretum
of Gratian by identifying the Law of Nature with the law
of God, as the Roman jurists had identified the ius gentium
with the Law of Nature. According to the canonical
doctors, the law revealed to man in natural reason is no
less truly revealed and no less divine than any specific precept of Scripture; it is of paramount and universal obligation, and no positive precept of any law human or divine
can be set up against it. If any specific revelation appears
to contradict the Law of Nature, it must have been
wrongly interpreted.
Our founders of the thirteenth century, Raleigh an~
Pateshull and Henry of Bratton, were themselves ecclesiastics. They were more or less learned in the canon law;
they must have known what the professed canonists were
doing. It is not credible that a doctrine which pervaded
all political speculation in Europe, and was assumed as a
common ground of authority by the opposing champions
of the Empire and the Papacy, should have been without influence among learned men in England. If it be asked why
the sages of the Common Law did not expressly refer to the
Law of Nature, the answer is that at no time after, at latest,
the papal interference in the English politics of the first half
of the thirteenth century, was the citation of Roman canonical authority acceptable in our country, save so far as it was
necessary for strictly technical purposes. Besides, any
such citation might have been construed as a renunciation
of independence, or a submission of questions of general
policy to the judgment of the Church. These considerations appear sufficient to explain why “it is not used among
them that be learned in the laws of England to reason what
thing is commanded or prohibited by the Law of Nature.”
Since the Middle Ages the Law of Nature or of Reason,
besides its distinct manifestations in foreign systems, has
been a principal o’r influential factor in developing the fol-
lowing branches of jurisprudence :—Equity, the Law
Merchant, the Law of Nations, the general application,-

within the sphere of municipal law, of the principles of
natural justice and reasonableness, and the body of rules
for the choice of law and jurisdiction, and the application
of foreign law, which we sum up under the head of Conflict of Laws or Private International Law. These are all
of frequent importance in our daily practice; it is becoming
less and less possible for the man who would be an accomplished lawyer to neglect any of them. We are
now concerned not to trace the leading principles into their
various consequences, which is the office of special treatises, but to observe how the Common Law has not only
adopted but assimilated them, and has thereby enriched its
resources for doing justice without losing anything of its
individual character. it was with our law as with a young
commonwealth growing in wealth and strength. At first we
lived in fear of surprises and usurpations; we were suspicious of foreign influence not because it might be bad, but
because it was foreign; we were jealously insular and held
strangers at arm’s length. When we had assured our existence and independence we opened our gates. We
welcomed new settlers with their arts and industries; we
became willing and eager to make their accomplishments
our own. But we held fast to our national genius, and
gave our fullest welcome to those who would enter into
our national life no longer as strangers but as citizens.
Natural justice is good for the emergencies of unsettled
times and extraordinary occasions, but precarious. It is
made a permanent possession, secured against caprice and
degeneration, only when it is embodied in legal justice.
Equity, as is well known, grew out of the King’s special
authority and duty to supplement the defects of the ordinary law and reinforce the weakness of its procedure. The
early Chancellors did not disclose the sources of their inspiration; probably they had as good grounds of expediency for not talking about the Law of Nature as the common
lawyers. Certainly they intended and endeavored to
follow the dictates of natural reason; and if their version
of natural justice was somewhat artificial in its details, and
bore a decided civilian or canonical stamp, this was only to
be expected. Some centuries later, when British judicial
THE EXPANSION OF THE COMMON LAW 177
officers in India were instructed to decide, in -the absence
of any native law applicable to both parties, according to
“ justice, equity, and good conscience,” the results bore,
even more manifestly, the stamp of the Common Law.
But of this we shall have to say a word later. The Court
of Chancery, having passed through its early stage of
doing battle with obstinate oppressors of the poor and
deniers of right, found itself charged, by means of its jurisdiction over trusts, with the administration of estates and
the adjustment of intricate and conflicting claims to property. Valiant in the cause of good conscience, the Court
made the attempt to attain perfect justice, and, lest any
form of fraud should escape, spread its nets with infinite
ingenuity. Some of you may remember the terribly multifarious contents of the heading "Constructive Fraud" in
the old-fashioned books on equity. Logically, nothing
could be less defensible than such a catalogue, or more
bewildering to young students. Thirty years ago I was
so bewildered, at any rate, that I could see no way out of
the tangle unless I cleared niy head by writing a book
myself—and I did. Historically, this jumble of diverse
matters did more or less faithfully represent an actual process. A’s conduct, let us say, is admitted to be fraudulent,
and fit to be restrained by the Court. B’s conduct is
rather like A’s, and C’s is rather like B’s; therefore let B
and C be restrained, though fraud cannot be proved. So
was natural reason driven to work by sap and mine rather
than by direct attack, the leaders of the Common Law not
being yet bold enough to aid it openly. The Court’s operations, carried out under these conditions, were too much
apart from common understanding, and ran into excessive
refinement. The natural reason of just men was overlaid
with elaborate artifices, and safeguards were multiplied at
a cost out of all proportion to the substance of what was to
be preserved. It was forgotton that a fairly good working
decision rendered within a moderate time is better than an
ideal decision postponed for an indefinite time, and that
decisions which are to be respected by the community at
large should be intelligible as well as just. Not content
,with requiring integrity, the Court sought to impose a
178 COLUMBIA LAW REVIEW.
standard of-prudence and vigilance beyond the powers of
ordinary mortals, and barely compatible with the ordinary
conduct of business. Thus, with the best intentions, it deposed the reasonable man of the Common Law or the bonus
paterfamilias of the Civil Law to set up a monster of impossible caution, and put many really innocent persons in situations of great hardship. More than once in recent times
legislation was found necessary to abolish or mitigate these
inconveniences. In England the fusion of legal and equitable jurisdiction under the Judicature Acts since 1575,worked
out in the judgments of a single Court of Appeal wielding
comprehensive powers and including judges trained in both
systems, has saved our equity jurisprudence, not too soon,
from being righteous overmuch. Conscientiousness is
good; the standard of the Common Law itself is in many
respects higher than what commonly passes muster among
men of good business repute, and it wouldT be disastrous if
it were lowered. Still the conscience of the Court, if it is
to be an effective power, must not run away from the common sense of mankind. Perhaps the best example of the
sound and legitimate work of equity, proceeding on broad
principles of justice and convenience, and giving permanent definition to reasonable practice tried by long experience, is to be found in the law of partnership. That law
is modern and self-contained; it owes very little to early
precedents and hardly anything to legislation; in about a
century it grew to a condition so settled and so acceptable
as to be ripe for codification. In 1890 it was codified in
England, and no material fault has been found with the
result. The commissioners on uniformity of legislation
who have already done so much excellent work in the
United States are now turning their attention to the same
subject, and it may not be many years before we see a substantially identical law of partnership enacted for the
English-speaking world; enacted, as was the Negotiable
Instruments Law, not by the invention of any one man
or generation, but on the firm base of the combined legal
and commercial reason of several generations.
The Law Merchant, as it existed through the Middle
Ages, was undoubtedly a body of cosmopolitan custom,
resting its claim to allegiance not on any express reception

by municipal authority but on its intrinsic reasonableness
evidenced by the general consent alid usage of the persons
concerned. It was recognized and constantly described as
being part of the Law of Nature. Thus Sir John Davies,
writing in the first quarter of the seventeenth century,
said: “The law merchant, as it is a part of the law of nature and nations, is universal and one and the same in
all countries in the world.” Much earlier, in 1473, in the
celebrated case of the fraudulent carrier which is the ultimate authority for the doctrine of larceny by breaking
bulk, Bishop Stillington, Edward IV’s Chancellor, had laid
down that suits between merchant strangers ought to be
determined by the law of nature in the Chancery. The
king has jurisdiction by the fact of the stranger’s coming
into the realm, but he must exercise it according to the law
of nature which some call the law merchant, and which is
universal throughout the world. We learn from Malines’
in his Lex Mercatoria, that in practice the Chancellor referred such causes to be determined by a commission of
merchants, and that this did not conduce to expedition.
Meanwhile the Common Law had gone very near to recognizing the custom of merchants, it would seem rather as
a kind of personal law than on any more general ground.
We have two examples in the late Year Books of Edward
I of suits between merchants in the King’s courts being
pleaded according to the law merchant. 2 It does not appear why this practice was discontinued. Later we find
allegations of local customs which look very much as if
they were part of the general law merchant, and were
pleaded in that special form only to compel the Court to
take notice of them.3
Perhaps it was as well that the reception of the Law
Merchant into the Common Law was deferred until it
could be received deliberately and in a mature form. In
the eighteenth century the law of nature had been recast
by Grotius and his successors in a shape fitted for modern
use, and without prejudice to its permanently valuable elements. The adoption of the Law Merchant, under the

directing genius of Lord Mansfield, was really a develop-
ment of the same process, as was also the introduction of
equitable methods into our ordinary legal procedure
through the machinery of the common courts. No further
comment on Lord Mansfield’s work is called for here; it is
as well known as anything in the history of our law, and
its praise is recorded in judgments which are themselves
classical. But it is important to observe that the Law
Merchant was not incorporated into our system, as some
have contended, as a fixed body of rules incapable of addition. It is still in fact a living body of custom, and English decisions have quite lately recognized this fact. We
now hold that a new general mercantile usage may be
proved, and that, once proved, the Courts will thenceforth
take judicial notice of it. On the other hand, as there is
a complete incorporation of the Law Merchant in the Common Law, so there must be a certain conformity. The Law
Merchant is not a foreign law, or the custom of a particular class, to be recognized and applied, in substitution of
the Common Law, in appropriate circumstances; it is an
integral part of our law itself. Therefore the settled principles applicable to men’s ordinary affairs cannot be displaced, or settled forms dispensed with, merely for the sup-
posed convenience of business. The seventeenth section
of the Statute of Frauds may be a wise enactment or not;
but we are not free to disregard it in a court of justice because it is the custom of a particular trade to rely on bare
spoken words or unsigned notes. Lord Mansfield himself
endeavored to reduce the requirement of consideration for
informal contracts to a mere rule of evidence inapplicable to commercial transactions in writing, but the attempt
was unsuccessful. It is useless to speculate on what might
have happened if there could have been a Lord Mansfield
in the fifteenth century. The Law Merchant has had to
pay something for the rights of full citizenship, but the price
was moderate and inevitable.
The history of the other great cosmopolitan offshoot of
the Law of Nature, namely international law, is not within
our present scope. But I cannot refrain from pointing out
the fallacy of one reason confidently given by English
THE EXPANSION OF THE GOMMON LAW. 181
jurists of the so-called analytical school, any time during
the last half century, for not allowing the law of nations to
be truly law at all. It is said that a system of rules cannot
be law when it lacks the sanction of a tribunal and of regular decisions; and the view that international law depends
merely on convention (which Lord Stowefl declared to be
fit only for Barbary pirates) may be found not only in text
books, but in reported judgments given in cases of great
importance. I do not admit the validity of the argument,
if the fact were as alleged; but the supposed fact is in
truth subject to large exceptions. Not only international
questions of allegiance and territorial jurisdiction, of the
existence and consequences of war between foreign powers
(whether officially recognized as sovereign states or not)~
of blockade and its incidents, and the like, may be and frequently. have been the subjects of decision in municipal
courts; but a material part of the law of war, namely the
law of prize, has been administered, and still may be, by
courts of admiralty, and expressly as an international and
not as a local law. Prize Courts administer the law of nations and have never purported to administer anything
else. “The seat of judicial authority is locally here, in the
belligerent country, according to the known law and practice of nations, but the law itself has no locality.” This is
only a sample of Lord Stowell’s utterances. No doubt is
possible that he conceived himself to be administering a
law that was ius gentiuin in the fullest sehse, a rule not of
local but of universal obligation, The same view has been
consistently held and applied in the Supreme Court of the
United States; I should rather think, indeed, that American jurists regard it as elementary. Thus, although it is
true that for some parts of the law of nations there is at
present no tribunal, or none with coercive jurisdiction, it is
equally true that a considerable part of it is actually within
the sphere of positive jurisprudence.
fn our system the Law of Nature has formally retreated
from one untenable position; but the position, as we shall
immediately see, had never been effectively occupied. It
was a current opinion arxiong the medieval doctors that
rules of positive municipal law were controlled by the law

of nature, and not binding if they were contrary to it;
though some advocates of the Emperor’s independent authority in secular matters, as against the claim of universal
supremacy for the Pope, avoided inconvenient consequences by tempering the general proposition with a rather
strong presumption that the acts of the lawful sovereign
were right. Opposition to princes and rulers in vindication
of the law of nature was possible, but at the opposer’s peril
if he were mistaken, and not to be lightly entered upon. So
limited, this natural right can hardly he distinguished
from the ultimate moral right, admitted by all modern
publicists, of resisting an intolerably bad government.
However, the doctrine without its politic justification
found an echo in England, whei5 the King’s judges always
looked on legislative interference with some jealousy—a
jealousy too often warranted by the unworkmanlike manner in which Parliament has laid hands on the Common
Law. We find a series of dicta, extending to the early
part of the eighteenth century, to the effect that statutes
contrary to natural justice or “common right” may be
treated as void. This opinion is most strongly expressed
by Coke, but, like many of his confident opinions, is extra-judicial. Although Coke was no canonist, we may be
pretty sure that it was ultimately derived from the canonist
doctrine prevailing on the Continent of Europe. In England it was never a practical doctrine. The nearest approach to real authority for it is a case of the 27th year of
Henry VI, known to us only through Fitzherbert’s Abridgment, where the Court held an Act of Parliament to be
inoperative, not because it was contrary to natural justice,
but because they could make no sense of it at all. At this
day the Courts have expressly disclaimed any power to
control an Act of Parliament. Blackstone characteristically talks in the ornamental part of his introduction about
the law of nature being supreme and, when he comes to
particulars, asserts the uncontrollable power of Parliament
in the most explicit terms, following herein Sir Thomas
Smith, a civiliall whose political insight was much greater
than that of the common lawyers of his time. It hardly
needs to be pointed out that, in states where there is a dis-

tinction between’ a written constitution, or fundamental
constitutional laws however called, and ordinary legislation,
the question whether any particular act of the legislature
is or is not in accordance with the Constitution depends
not on any general views of natural justice, but on the interpretation of the constitutional provisions which are the supreme law of the land. But I may remind you in passing that
such a distinction, while it is necessary in a federal constitution, is also quite possible in a state having a single centralized government, and exists at this day in a majority of the
civilized commonwealths of the world. The omnipotence
of the British Parliament, on which English jurists have
been too apt to build their theories of sovereignty and
legislation, is really exceptional, On its own ground, however, it is established beyond any doubt.
B. NATURAL JUSTICE IN THE COMMON LAW.—The real
and fruitful conquests of the principle of natural justice or
reasonableness in our law belong to its modern growth.
Students fresh from striving with the verbal archaism of
our law-books must find it hard to realize that the nineteenth century, after the thirteenth, has been the most vital
period of the Common Law. The greater part of our
actual working jurisprudence was made by men born in
the early years of that century, the contemporaries of Darwin and Emerson. A hundred years ago the law of contract was, to say the least, very far from complete, and the
law of negligence and all cognate subjects was rudimentary. No such proposition could then have been
enunciated as that every lawful man is bound (exceptions
excepted) to use in all his doings the care and caution, at least,
of a man of average prudence to avoid causing harm to his
neighbors, and is entitled in turn to presume that they will
use reasonable care both for him and for themselves. Now
it has become a commonplace, and the wayfarer who reads,
as he approaches a railroad crossing, the brief words of
warning “Stop, look, listen,” little thinks that they sum up
a whole history of keen discussion. The standard of a
reasonable man’s conduct has been taken by courts from
the verdicts of juries, and consolidated into judicial rules;
and we have a body of authority covering all the usual oc
184 COLUMBIA LAW REVIEW.
casions of men’s business and traffic, and already tending
to be, if anything, too elaborate. All this owes very little
indeed to early precedents. The medieval feeling seems to
have been rather that, outside a few special and stringent
rules, a man should be held liable only for default in what
he had positively undertaken; and, in days when mechani
cal arts were few and simple, and the determination of dised facts was still a rude and uncertain process, this may
have served well enough. But the law was capable of
growing to the demands of new times and circumstances; its
conclusions in detail were not dogmas, but flexible applications of living and still expanding principles. The knowledge and resources of a reasonable man are far greater
in the twentieth than in the sixteenth or the eighteenth
century, and accordingly so much the more is required
of him. A defendant must clear himself by showing, not that
he acted to the best of his own judgment, or with a degree
of prudence that would have been sufficient in the Middle
Ages, but that his action was such as is to be expected
here and now from a man competent, so far as any special
competence was required, in the business he was about,
and otherwise not below the general standard of a capable
citizen’s information, intelligence and caution. A plaintiff,
on the other hand, is not free to neglect obvious opportunities of avoiding harm, though the defendant’s negligence
may have put him in danger in the first instance. He must
not charge the defendant with consequences which he himself had the means of averting, and could finally have
averted by the exercise of ordinary prudence. This is,
broadly stated, the doctrine of contributory negligence, a
doctrine in no way formal or technical, notwithstanding
ingenious attempts to make it so, and founded solely on
general principles of reason and convenience, and on the
inherent power of the Common Law to mould its rules in
accordance with those principles, as the habits of men’s lives
are modified by new inventions, and new cases, produced
by such modifications, arise for determination. It may be
supported by the analogy, so far as that goes, of some
opinions of the classical Roman lawyers in their interpretations of the Lex Aquilia, themselves resting on like
THE EXPANSION OF IHE COMMON LAW. 185
grounds of natural reason; but its growth has been quite
independent. Even more remarkable is the formation,
dating from less than forty years ago, (though one or two
eminent judges threw out hints of it earlier) of a rule or
body of rules demanding a special and intensified caution
from the occupiers of what we call, for this purpose, fixed
property. The term is not quite adequate for some of the
later developments of the doctrine, but is sufficiently understood. I have ventured to group these rules, which are
still increasing in importance, under the rubric of ‘ Duties
of insuring safety.” The justification of their existence lies
not in any ancient maxims or forms of pleading, but in the
intrinsic and indefeasible competence of the law to stand in
the forefront of social morality. We have powers of controlling the material world, and holding its various energies
ready to be directed to our ends, which were wholly unknown to our forefathers. With those powers have come
risks which were equally unknown to them. Going beyond
the letter of their books, we have extended the old remedies
to meet those risks; and yet we are faithful to the spirit of
the medieval sages, and something more, for we have called
on the archaic strictness of the law of trespass to give a
hand to the deliberate exigency of our modern policy.
Probably there was nothing in the early rules of cattle
trespass and the like more politic or subtle than the com.
mon archaic assumption that a given set of external facts,
if they do not make a man liable conclusively and without
qualification, will not make him liable at all. In following and enlarging such rules we have really set
them on a new foundation. Responsibility to one’s neighbors increases in proportion as one’s undertaking involves
elements of common danger; and there comes a point of
risk at which nothing short of “consummate care” will
serve, and no prudence is allowed to count as such in law
which has not proved sufficient to avert disaster in fact. It
is not for me to discuss here whether the Common Law, in
the jurisdictions which accept this last doctrine—for it is
not everywhere accepted—has not . been tempted into an
excess of zeal against negligence, as Equity once was against
fraud. The zeal that devours is better, at any rate, than sloth
that rusts. There must be fluctuations and now and then

a false step in a secular process like that of our science.
We think no less of the achievements of great masters in
the graphic arts because they reveal to the curious eye
little slips of the tool or of the brush, the traces of a changed
purpose or a corrected execution which are technically
known as pentirnenti.

are not wanting. Powers of a judicial nature are frequently exercised by governing bodies of various kinds,
trustees of public institutions, directors of companies, comittees of clubs, and the like, who have a statutory or conventional authority over their officers and members, and
are invested with the duty of hearing and determining
complaints of misconduct. Dismissal from an office of
profit, or deprivation of membership and its incidental
rights in corporate or quasi-corporate property, may be the
result. From such decisions the Court will not entertain
an appeal on the general merits. But it will not allow the
rules of universal justice to be disregarded. Whatever
forms are prescribed in the particular case must be observed; the person charged with misconduct must not be
condemned without adequate notice and an adequate opportunity of being heard; and the decision must be rendered
in good faith for the interest of the society or institution
whose authority is being exercised. Exceptionally, for
reasons of policy, there may be an absolute as distinguished
from a judicial discretion, a purposely unlimited power to
dismiss or deprive without giving any reason at all. Such
a power must be expressly conferred by legislation or by
the terms of a contract to which the person to be affected
is a party. There may be very good cause for its existence; but such express provisions, when they exist, do not
impeach the validity of the general principle.
There is a much more delicate question somewhat anal-
ogous to this: namely, whether a municipal court can disregard the judgment of a foreign court of competent juris-
diction merely on the ground that the result is manifestly
contrary to natural justice. On the whole the acceptable
opinion would seem to be that such a power exists, but that
it is a reserved power to be exercised only with the greatest caution and in an extreme case. We have learned to
THE EXPANSION OF THE COMMON LAW. 187
say that the verdict of a jury will not be set aside merely
because the court does not agree with it, but only if it appears to be such as no reasonable jury could have arrived
at upon the evidence. The judgment of a foreign court
acting within its jurisdiction must be entitled to as much
respect.
I have endeavored to show that the Law of Nature is
not, as the English utilitarians in their ignorance of it's
history supposed, a synonym for arbitrary individual preference, but that on the contrary it is a living embodiment
of the collective reason of civilized mankind, and as such is
adopted by the Common Law in substance, though not always by name. But it has its limits; they are pointed out
in the very earliest Aristotelian exposition, and it must be
admitted that attempts to overstep them have sometimes
led to failure. Natural justice has no means of fixing any
rule to terms defined in number or measure, nor of choosing one practical solution out of two or more which are in
themselves equally plausible. Positive law, whether enacted or customary, must come to our aid in such matters.
It would be no great feat for natural reason to tell us that
a rule of the road is desirable; but it could never have told
us whether to drive to the right hand or to the left, and, in
fact, custom has settled this differently in different countries,
and even, in some parts of Europe, in different provinces of
one state. In the eighteenth century a bold and ingenious
attempt was made in England to establish copyright at
common law by arguments drawn from the law of nature;
and it seemed to be on the point of success. For a time
the weight of opinion was in its favour. But such a right,
if it existed, could not be limited in time; it must be perpetual if it was anything extending beyond the author’s
lifetime. An argument might perhaps be framed for a
right exercisable only by the author in person, and therefore coextensive with his life; but this would not have
satisfied authors. Plausible reasons for what is called
property in ideas” were certainly forthcoming; they are
still sometimes urged by men of letters and lay publicists.
But in a later generation the tide of legal opinion had
turned. ln the middle of the nineteenth century both sides
were ably supported among the judges, but the House of
188 COLUMBIA LAW REVIEW.
Lords was unanimous (though actual decision of the point
was not called for) against the existence of the alleged
right; and this on grounds of general reason and convenience, in other words, of natural justice. It may be doubted
whether the law of nature be competent, in any case, within
or even outside the bounds of the Common Law, to invent
definite new forms of property. But, however that may
be, general consent is the only practical warrant for the
adoption of any suggested rule as beipg dictated by universal justice; and here the only general consent which could
be inferred from the conflict of opinions was a consensus
that authors ought to have some kind of reasonable security
for enjoying the fruit of their labour. The question what
the kind and amount of protection shall be, when once a
limited protection is admitted in principle, can only stand
remitted to legislation; and that way has in fact been taken
everywhere. The problem is now not to find a philosophic
basis, but to get the copyright laws of civilized countries
reduced to tolerable simplicity, and brought, if possible, to
an approximate uniformity. There is an antecedent right
to restrain the publication of unpublished matter, often erroneously called copyright before publication, and sometimes treated as an incident of property, sometimes as
arising from a presumed contract or term of a contract.
This does appear to rest, in the last analysis, on considerations of natural justice more than on any satisfying deduction from positive ownership or obligation. Of this class
of rights not much can be said with confidence at present.
It is being slowly developed by occasional decisions, but,
so far as authority goes, it is neither well defined nor
adequately explained, and does not seem likely to be so for
several years to come. One day the time will be ripe for
clear light to be struck out from a leading judgment or
series of judgments, and then,a new chapter of natural reason will be added to our law, and we shall all wonder why
so plain a rule was not understood sooner. The jurists of
Continental Europe, not without provocation, consider our
lawyers lamentably ignorant of natural law; some English
writers, half a century behind their time, still maintain the
obsolete Benthamite aversion to its name; meanwhile our
Courts have to go on making a great deal of law which is
THE EXPANSION OF THE COMMON LAW. 189
really natural law, whether they know it or not. For, as
we said at the outset of these lectures, they must find a
solution, with or without authority, for every case that
comes before them; and general considerations of justice
and convenience must be relied on in default of positive authority. There is no reason why they should not
be openly invoked, for the alternative method of pretending
to follow authority where there is really none is now discredited. These general considerations are nothing else
than what our ancestors of the Middle Ages and the
Renaissance understood by the Law of Nature. lt is not
within our province to show here how a term with a venerable history, and capable of perfectly rational application,
came, after the disruption of the scholastic traditions,
to be perverted and misconceived for nearly two centuries.
Just now there is a group of questions before courts of
common law both in America and Europe, arising out of
the rapid modern development of trade combinations, which
go to the very foundation of the law of personal liberty
and of civil wrongs. Individuals, in our system of society,
cannot effectually protect their common interests otherwise
than by common organized action. But this very protective action, in itself legitimate, easily reaches a point where
it creates powers liable to grave abuse, and, even without
manifest abuse, bears hardly on dissentient individuals
within the sphere of interest in question,on persons and
classes having opposed ‘interests, and, in possible and not
infrequent cases, on the common weal at large. The problem is nothing less than to reconcile the just freedom of new
kinds of collective action with public convenience and the
ancient and just independence of the individual citizen. It
would be idle here to express any opinion upon the issues
involved, or to attempt any forecast of the ultimate solution. Such an attempt would lead to a digression altogether disproportionate to the matter in hand, and still too
brief to have any value of its own. This much is certain,
that no merely technical resources of the law will suffice
for the task. In whatever jurisdiction the decisive word is
spoken, it will be founded on knowledge of the world and
on broad considerations of policy. Natural law will have,
in other words, a large and probably a dominant part in it.
190 COLUMBIA LAW REVIEW.
The Common Law, then, has largely enriched and is
still enriching itself by associating the Law of Nature with
its authority. The Law of Nature has in turn carried the
spirit and much of the substance of the Common Law to
regions where that law never claimed or has even expressly
disclaimed formal jurisdiction. A professor of the common
law set down in British India without previous information
would find himself, on the whole, in a familiar atmosphere of
his own law. He would observe that Asiatic suitors, living
under customs intimately bound up with their religions, are
judged by those customs in matters of religion, marriage
and inheritance. Allowing for this exception, he would be
prone to infer that the Common Law had at some time and
in some way been received as governing civil relations in
general. But in fact our Courts in India do not profess,
outside the limited statutory jurisdiction of the High
Courts of the Presidency towns over European British
subjects; to administer English law as such. In the early
days of our trading settlements European merchants were
presumed, according to the universal custom of Asia, which
was also the custom of merchant communities in Europe in
the Middle Ages, to carry their own law with them. A
charter of Charles II, due to the acquisition of Bombay,
seems to have contemplated the establishment of a court
or courts to administer the law merchant to traders. It
does not appear that this provision came into effect; in any
case the subsequent adoption of the law merchant by the
Common Law superseded it. A century later and on the
other side of India. the East India Company’s courts, in
the territory which the Company governed as the nominal delegate of the Mogul emperors, aimed at doing justice
according to the native laws of the suitors. But the parties were often of different provinces or religions, or both,
not owing obedience to any common rule; and for many of
the growing modern relations of business there was no
rule at all to be found in any native law. This being so, a
Bengal Regulation instructed the Company’s courts, in
1793, “to act according to justice, equity, and good con:
science”; and this, being followed in the same or like words
by the other provincial Regulations, became the general
rule of the Company’sjurisdiction. In terms this amounted
THE EXPANSION OF THE COMMON LA W. 191
to a comprehensive enactment of the Law of Nature. Such
would be its obvious meaning to any publicist down to the
end of the eighteenth century. But the Law of Nature, as
we have already noted, does not provide a detailed system
for the guidance of municipal tribunals. It can tell us that
men ought to keep faith and perform their contracts; it
can no more tell us what are the requisites of a lawfully
binding contract at Benares than what they are at Providence, at New Haven or at Iowa City. British magistrates had to do the best justice they could, and the only
justice they were familiar with was the justice of the Common Law. Thus, under the name of justice, equity, and
good conscience, the general law of British India, save so
far as the authority of native laws was preserved, came to
be so much of English law as was considered applicable, or
rather was not considered inapplicable, to the conditions of
Indian society. At this day the reported decisions of the
English courts are freely, perhaps too freely, cited by keen-witted native pleaders all over India, and relied on by
Hindu and Mahometan judges of the Indian High Courts,
of whom some would be worthy companions to any of our
own chiefs. There are four independent jurisdictions in
India whose decisions are reported (Allahabad, Bombay,
Calcutta and Madras); but an appeal lies from them all to
the Judicial Committee of the Privy Council, and the
divergencies have not been very serious. All the High
Courts endeavor, so far as consistent with local legislation,
to keep abreast of the progress of English law at home.
A somewhat analogous process took place in the Middle
Ages when, in the French provinces of customary law, the
Roman law, though not received as binding, enjoyed a persuasive authority as being an embodiment of written reason, and impressed its own character on a formally inde-
pendent jurisprudence. Much of the Anglo. Indian law has
been consolidated in Codes within the last generation or
thereabouts; this was not the imposition of new law by
legislative authority, but, in intention at least, the affirmation of existing law and practice, with a certain number of
specific amendments and the determination of a certain
number of controverted points. I ought to mention, perhaps, that the history of criminal law in British India
192 COLUMBIA LAW REVIEW.
stands to some extent apart. The Company’s courts attempted to administer Mahometan penal law, which they
found in possession. But the experiment proved unsatisfactory, and after a variety of makeshifts and long delay a
Penal Code, being a simplified version of English criminal
law, was enacted for British India in 1861. The original
draft had been prepared many years earlier by a Commission of which Macaulay was the leading member; the
text bears his mark plainly enough, and the introductory
minute is now part of his collected works. This was the
earliest of the Anglo-Indian Codes, and has been the most
successful. It is remarkable that our criminal law, not-withstanding its conspicuous defects of form, has almost
everywhere prevailed over competing systems, even where
the Common Law was not received as a whole. Witness the
Province of Quebec, where the Civil Code represents the
old French law of the colony modified by free use of the
Napoleonic Code, and in some particulars by English influence, but the criminal law is the substantially English
Criminal Code of the Dominion. The Indian Penal Code
has itself become a centre of influence, and a model for
more or less close imitation, not only among the native
States of India, (with whose domestic legislation the government of India does not interfere, provided that the essentials of good government are respected) but in Ceylon,
the Sudan, and some other territories under British dominion or protection.
It is curious to reflect, at this day, that a generation or
two ago, when the intei-nal expansion and the external con-quests of the Common Law were in full tide, it was a prevalent opinion among thoughtful and learned persons in
England that the judicial development of the law had seen
its best days, and the sceptre had passed to legislation.
Historical formulas about stages and periods may be useful servants; they must not be allowed to become masters.
Very good of its kind, but still of that kind, is the maxim,
originated, I believe, by Sir Henry Maine, that there is an
age of fictions, an age of equity, and an age of legislation.
The positive truth contained in it is of great value. Equity
taken in a large sense, the free constructive development of
law consciously directed to ends of justice and conve

nience, is possible only when jurisprudence has become or
is in the way of becoming a science. Again, the scale and
importance of legislation in the world we now live in depend on the political conditions of modern society as a
whole as well as on the existence of a formally competent
legislature. But we have no right to make the negative or
exclusive inference that equity, when it came in, left no
room for fictions, and that legislation in turn has superseded
equity. No such inference is warranted by the actual history of the law. One of the most brilliant and successful
fictions of the Common Law, quite lately confirmed to the
full in England by the House of Lords, is less than half a
century old, I mean the implied warranty of authority
which is attached to the acts of a professed agent. The
authority of Equity, whether we take it in the artificial
sense of the law and remedies formerly peculiar to the
Court of Chancery, or in the wider sense just now mentioned, has not diminished but increased in the last generation. Legislation itself is to no small extent conditioned
by the continuing evolution of professional jurisprudence.
The law cannot afford to throw away any of its resources;
we must hold fast to them all. Many are the books of
practice, once in every lawyer’s hands, that have had their
day and are stacked like the obsolete weapons of European
armories, a “dumb dread people,” if I may pervert a phrase
of Mr. Swinburne’s, who sit forgotten on the upper shelves
of Austin Hall and Lincoln’s Inn. Forms of pleading and
rules of procedure pass away like the matchlock and the
pike; but our fundamental methods and traditions, like the
principles of the art of war, do not pass away. Julius
Ceasar would know what to do with a cyclist battalion, and
Gustavus Adolphus would recognize his own ideas in the
machine gun. Mahan expounds the strategy of the modern
battleship in the names of Raleigh and Nelson. That earlier Raleigh who was Henry of Bratton’s master would not
be afraid to grapple with code pleading, and the judges who
framed the Statute of Wales would not be behind John
Marshall in building up a federal jurisdiction. The old
flag, the old watchwords, the old discipline, the latest
knowledge and the newest arms—these are the approved
instruments of victory in peace as in war. For whom is
194, COLUMBIA LAW REVIEW.
the next campaign of the law? For you to whom I speak, you
who are of age to take up the heritage of our fathers. The
Common Law, here and in England and round the world,
looks to your youth and strength to improve it as good husbandmen. Remember that you are servants of the commonwealth, and are devoted not to a trade but to a science.
Remember that the law of which we are ministers is a law
of the courts and of the people; remember that its vital
competence to satisfy the needs of the modern State is fed
from its ancient Germanic roots of publicity and independence. If writs run in the name of King Edward VII from
the North Sea to the Pacific, it is largely because King
Edward I was a faithful servant of his people and of the law.
Remember that it is your office as lawyers to give authentic
form to the highest public morality of which you are capable as citizens, and that this office belongs of right no less
to the Bar than to the Bench. Remember that our spiritual
fellowship transcends political boundaries, and is as worldwide as our profession is honourable and its traditions venerable. Remember that our Lady the Common Law is not
a task mistress, but a bountiful sovereign whose service is
freedom. The destinies of the English-speaking world are
bound up with her fortunes and her migrations, and its
conquests are justified by her works. My words are over,
and for any life to come they must look to your deeds. The
empire of the Common Law is in your hands.
