An Introduction to the Principles of Morals and Legislation/Chapter XVII

§1. Limits between Private Ethics and the Art of legislation

I. So much for the division of offenses in general. Now an offense is an act prohibited, or (what comes to the same thing) an act of which the contrary is commanded, by the law: and what is it that the law can be employed in doing, besides prohibiting and commanding? It should seem then, according to this view of the matter, that were we to have settled what may be proper to be done with relation to offences, we should thereby have settled every thing that may be proper to be done in the way of law. Yet that branch which concerns the method of dealing with offences, and which is termed sometimes the criminal, sometimes the penal, branch, is universally understood to be but one out of two branches which compose the whole subject of the art of legislation; that which is termed the civil being the other. Between these two branches then, it is evident enough, there cannot but be a very intimate connection; so intimate is it indeed, that the limits between them are by no means easy to mark out. The case is the same in some degree between the whole business of legislation (civil and penal branches taken together) and that of private ethics. Of these several limits however it will be in a manner necessary to exhibit some idea: lest, on the one hand, we should seem to leave any part of the subject that does belong to as untouched, or, on the other hand, to deviate on any side into a track which does not belong to us.

In the course of this enquiry, that part of it I mean which concerns the limits between the civil and the penal branch of law, it will be necessary to settle a number of points, of which the connection with the main question might not at first sight be suspected. To ascertain what sort of a thing a law is; what the parts are that are to be found in it; what it must contain in order to be complete; what the connection is between that part of a body of laws which belongs to the subject of procedure and the rest of the law at large:— all these, it will be seen, are so many problems, which must be solved before any satisfactory answer can be given to the main question above mentioned.

Nor is this their only use: for it is evident enough, that the notion of a complete law must first be fixed, before the legislator can in any case know what it is he has to do, or when his work is done.

II. Ethics at large may be defined, the art of directing men's actions to the production of the greatest possible quantity of happiness, on the part of those whose interest is in view.

III. What then are the actions which it can be in a man's power to direct? They must be either his own actions, or those of other agents. Ethics, in as far as it is the art of directing a man's own actions, may be styled the art of self-government, or private ethics.

IV. What other agents then are there, which, at the same time that they are under the influence of man's direction, are susceptible of happiness. They are of two sorts: As to other human beings, the art of directing their actions to the above end is what we mean, or at least the only thing which, upon the principle of utility, we ought to mean, by the art of government: which, in as far as the measures it displays itself in are of a permanent nature, is generally distinguished by the name of legislation: as it is by that of administration, when they are of a temporary nature, determined by the occurrences of the day.
 * 1) Other human beings who are styled persons.
 * 2) Other animals, which, on account of their interests having been neglected by the insensibility of the ancient jurists, stand degraded into the class of things.

V. Now human creatures, considered with respect to the maturity of their faculties, are either in an adult, or in a non-adult state. The art of government, in as far as it concerns the direction of the actions of persons in a non-adult state, may be termed the art of education. In as far as this business is entrusted with those who, in virtue of some private relationship, are in the main the best disposed to take upon them, and the best able to discharge, this office, it may be termed the art of private education: in as far as it is exercised by those whose province it is to superintend the conduct of the whole community, it may be termed the art of public education.

VI. As to ethics in general, a man's happiness will depend, in the first place, upon such parts of his behaviour as none but himself are interested in; in the next place, upon such parts of it as may affect the happiness of those about him. In as far as his happiness depends upon the first-mentioned part of his behaviour, it is said to depend upon his duty to himself. Ethics then, in as far as it is the art of directing a man's actions in this respect, may be termed the art of discharging one's duty to one's self: and the quality with which a man manifests by the discharge of this branch of duty (if duty it is to be called) is the of prudence. In as far as his happiness, and that of any other person or persons whose interests are considered, depends upon such parts of his behaviour as may affect the interests of those about, it may be said to depend on his duty to others ;or, to use a phrase now somewhat antiquated, his duty to his neighbour. Ethics then, in as far as it is the art of directing a man's actions in this respect, may be termed the art of discharging one's duty to one's neighbour. Now the happiness of one's neighbour may be consulted in two ways:
 * 1) In a negative way, by forbearing to diminish it.
 * 2) In a positive way, by studying to increase it. A man's duty to his neighbour is accordingly partly negative and partly positive: to discharge the negative branch of it, is probity: to discharge the positive branch, beneficence.

VII. It may here be asked, How it is that upon the principle of private ethics, legislation and religion out of the question, a man's happiness depends upon such parts of his conduct as affect, immediately at least, the happiness of no one but himself: this is as much as to ask, What motives (independent of such as legislation and religion may chance to furnish) can one man have to consult the happiness of another by what motives, or, which comes to the same thing, by what obligations, can he be bound to obey the dictates of probity and beneficence. In answer to this, it cannot but be admitted, that the only interests which a man at all times and upon all occasions is sure to find adequate motives for consulting, are his own. Notwithstanding this, there are no occasions in which a man has not some motives for consulting the happiness of other men. In the first place, he has, on all occasions, the purely social motive of sympathy or benevolence: in the next place, he has, on most occasions, the semi-social motives of love of amity and love of reputation. The motive of sympathy will act upon him with more or less effect, according to the bias of his sensibility: the two other motives, according to a variety of circumstances, principally according to the strength of his intellectual powers, the firmness and steadiness of his mind, the quantum of his moral sensibility, and the characters of the people he has to deal with.

VIII. Now private ethics has happiness for its end: and legislation can have no other. Private ethics concerns every member, that is, the happiness and the actions of every member, of any community that can be proposed; and legislation can concern no more. Thus far, then, private ethics and the art of legislation go hand in hand. The end they have, or ought to have, in view, is of the same nature. The persons whose happiness they ought to have in view, as also the persons whose conduct they ought to be occupied in directing, are precisely the same. The very acts they ought to be conversant about, are even in a great, measure the same. Where then lies the difference? In that the acts which they ought to be conversant about, though in a great measure, are not perfectly and throughout the same. There is no case in which a private man ought not to direct his own conduct to the production of his own happiness, and of that of his fellow-creatures: but there are cases in which the legislator ought not (in a direct way at least, and by means of punishment applied immediately to particular individual acts) to attempt to direct the conduct of the several other members of the community. Every act which promises to be beneficial upon the whole to the community (himself included) each individual ought to perform of himself: but it is not every such act that the legislator ought to compel him to perform. Every act which promises to be pernicious upon the whole to the community (himself included) each individual ought to abstain from of him: but it is not every such act that the legislator ought to compel him to abstain from.

IX. Where then is the line to be drawn?— We shall not have far to seek for it. The business is to give an idea of the cases in which ethics ought, and in which legislation ought not (in a direct manner at least) to interfere. If legislation interferes in a direct manner, it must be by punishment. Now the cases in which punishment, meaning the punishment of the political sanction, ought not to be inflicted, have been already stated. 2. If then there be any of these cases in which, although legislation ought not, private ethics does or ought to interfere, these cases will serve to point out the limits between the two arts or branches of science. These cases. it may be remembered, are of four sorts: Let us look over all these cases, and see whether in any of them there is room for the interference of private ethics, at the same time that there is none for the direct interference of legislation.
 * 1) Where punishment would be groundless.
 * 2) Where it would be inefficacious.
 * 3) Where it would be unprofitable.
 * 4) Where it would be needless.

X. 1. First then, as to the cases where punishment would be groundless. In these cases it is evident, that the restrictive interference of ethics would be groundless too. It is because, upon the whole, there is no evil in the act, that legislation ought not to endeavour to prevent it. No more, for the same reason, ought private ethics.

XI. 2. As to the cases in which punishment would be inefficacious. These, we may observe, may be divided into two sets or classes. The first do not depend at all upon the natured of the act: they turn only upon a defect in the timing of the punishment. The punishment in question is no more than what, for any thing that appears, ought to have been applied to the act in question. It ought, however, to have been applied at a different time; viz., not till after it had been properly denounced. These are the cases of an ex-post-facto law; of a judicial sentence beyond the law; and of a law not sufficiently promulgated. The acts here in question then might, for anything that appears, come properly under the department even of coercive legislation: of course do they under that of private ethics. As to the other set of cases, in which punishment would be inefficacious; neither do these depend upon the nature of the act, that is, of the sort of act: they turn only upon some extraneous circumstances, with which an act of any sort may chance to be accompanied. These, however, are of such a nature as not only to exclude the application of legal punishment, but in general to leave little room for the influence of private ethics. These are the cases where the will could not be deterred from any act, even by the extraordinary force of artificial punishment: as in the cases of extreme infancy, insanity, and perfect intoxication: of course, therefore, it could not by such slender and precarious force as could be applied by private ethics. The case is in this respect the same, under the circumstances of unintentionality with respect to the event of the action, unconsciousness with regard to the circumstances, and mis-supposal with regard to the existence of circumstances which have not existed; as also where the force, even of extraordinary punishment, is rendered inoperative by the superior force of a physical danger or threatened mischief. It is evident, that in these cases, if the thunders of the law prove impotent, the whispers of simple morality can have but little influence.

XII. 3. As to the cases where punishment would be unprofitable. These are the cases which constitute the great field for the exclusive interference of private ethics. When a punishment is unprofitable, or in other words too expensive, it is because the evil of the punishment exceeds that of the offence. Now the evil of the punishment, we may remember, is distinguishable into four branches: Now with respect to those original evils, the persons who lie exposed to them may be two very different sets of persons. In the first place, persons who may have actually committed, or been prompted to commit, the acts really meant to be prohibited. In the next place, persons who may have performed, or been prompted to perform, such other acts as they fear may be in danger of being involved in the punishment designed only for the former. But of these two sets of acts, it is the former only that are pernicious: it is, therefore, the former only that it can be the business of private ethics to endeavour to prevent. The latter being by the supposition not mischievous, to prevent them is what it can no more be the business of ethics to endeavour at, than of legislation. It remains to show how it may happen, that there should be acts really pernicious, which, although they may very properly come under the censure of private ethics, may yet be no fit objects for the legislator to control.
 * 1) The evil of coercion, including constraint or restraint, according as the act commanded is of the positive kind or the negative.
 * 2) The evil of apprehension.
 * 3) The evil of sufferance.
 * 4) The derivative evils resulting to persons in connection with those by whom the three above-mentioned original evils are sustained.

XIII. Punishment then, as applied to delinquency, may be unprofitable in both or either of two ways:
 * 1) By the expense it would amount to, even supposing the application of it to be confined altogether to delinquency:
 * 2) By the danger there may be of its involving the innocent in the fate designed only for the guilty.

First then, with regard to the cases in which the expense of the punishment, as applied to the guilty, would outweigh the profit to be made by it. These cases, it is evident, depend upon a certain proportion between the evil of the punishment and the evil of the offence. Now were the offence of such a nature, that a punishment which, in point of magnitude, should but just exceed the profit of it, would be sufficient to prevent it, it might be rather difficult perhaps to find an instance in which such punishment would clearly appear to be unprofitable. But the fact is, there are many cases in which a punishment, in order to have any chance of being efficacious, must, in point of magnitude, be raised a great deal above that level. Thus it is, wherever the danger of detection is, or, what comes to the same thing, is likely to appear to be, so small, as to make the punishment appear in a high degree uncertain. In this case it is necessary, as has been shown, if punishment be at all applied, to raise it in point of magnitude as much as it falls short in point of certainty. It is evident, however, that all this can be but guesswork: and that the effect of such a proportion will be rendered precarious, by a variety of circumstances: by the want of sufficient promulgation on the part of the laws: by the particular circumstances of the temptation: and by the circumstances influencing the sensibility of the several individuals who are exposed to it. Let the seducing motives be strong, the offence then will at any rate be frequently committed. Now and then indeed, owing to a coincidence of circumstances more or less extraordinary, it will be detected, and by that means punished. But for the purpose of example, which is the principal one, an act of punishment, considered in itself, is of no use: what use it can be of, depends altogether upon the expectation it raises of similar punishment, in future cases of similar delinquency. But this future punishment, it is evident, must always depend upon detection. If then the want of detection is such as must in general (especially to eyes fascinated by the force of the seducing motives) appear too improbable to be reckoned upon, the punishment, though it should be inflicted, may come to be of no use. Here then will be two opposite evils running on at the same time, yet neither of them reducing the quantum of the other: the evil of the disease and the evil of the painful and inefficacious remedy. It seems to be partly owing to some such considerations, that fornication, for example, or the illicit commerce between the sexes, has commonly either gone altogether unpunished, or been punished in a degree inferior to that in which, on other accounts, legislators might have been disposed to punish it.

XIV. Secondly, with regard to the cases in which political punishment, as applied to delinquency, may be unprofitable, in virtue of the danger there may be of its involving the innocent in the fate designed only for the guilty. Whence should this danger then arise? From the difficulty there may be of fixing the idea of the guilty action: that is. of subjecting it to such a definition as shall be clear and precise enough to guard effectively against misapplication. This difficulty may arise from either of two sources: the one permanent, to wit, the nature of the actions themselves: the other occasional, I mean the qualities of the men who may have to deal with those actions in the way of government. In as far as it arises from the latter of these sources, it may depend partly upon the use which the legislator may be able to make of language; partly upon the use which, according to the apprehension of the legislators the judge may be disposed to make of it. As far as legislation is concerned, it will depend upon the degree of perfecting to which the arts of language may have been carried, in the first place, in the nation in general; in the next place. by the legislator in particular. It is to a sense of this difficulty, as it should seem, that we may attribute the caution with which most legislators have abstained from subjecting to censure, on the part of the law, such actions as come under the notion of rudeness, for example, or treachery, or ingratitude. The attempt to bring acts of so vague and questionable a nature under the control of law, will argue either a very immature age, in which the difficulties which give birth to that danger are not descried; or a very enlightened age, in which they are overcome.

XV. For the sake of obtaining the clearer idea of the limits between the art of legislation and private ethics, it may now be time to call to mind the distinctions above established with regard to ethics in general. The degree in which private ethics stands in need of the assistance of legislation is different in the three branches of duty above distinguished. Of the rules of moral duty, those which seem to stand least in need of the assistance of legislation are the rules of prudence. It can only be through some defect on the part of the understanding, if a man be ever deficient in point of duty to himself. If he does wrong, there is nothing else that it can be owing to but either some inadvertence or some mis-supposal with regard to the circumstances on which his happiness depends. It is a standing topic of complaint, that a man knows too little of himself. Be it so: but is it so certain that the legislator must know more? It is plain, that of individuals the legislator can know nothing: concerning those points of conduct which depend upon the particular circumstances of each individual, it is plain, therefore, that he can determine nothing to advantage. It is only with respect to those broad lines of conduct in which all persons, or very large and permanent descriptions of persons, may be in a way to engage, that he can have any pretense for interfering; and even here the propriety of his interference will, in most instances, lie very open to dispute. At any rate, he must never expect to produce a perfect compliance by the mere force of the sanction of which he is himself the author. All he can hope to do, is to increase the efficacy of private ethics, by giving strength and direction to the influence of the moral sanction. With what chance of success, for example, would a legislator go about to extirpate drunkenness and fornication by dint of legal punishment? Not all the tortures which ingenuity could invent would compass it: and, before he had made any progress worth regarding, such a mass of evil would be produced by the punishment, as would exceed, a thousandfold, the utmost possible mischief of the offence.. The great difficulty would be in the procuring evidence; an object which could not be attempted, with any probability of success, without spreading dismay through every family, tearing the bonds of sympathy asunder, and rooting out the influence of all the social motives. All that he can do then, against offences of this nature, with any prospect of advantage, in the way of direct legislation, is to subject them, in cases of notoriety, to a slight censure, so as thereby to cover them with a slight shade of artificial disrepute.

XVI. It may be observed, that with regard to this branch of duty, legislators have, in general, been disposed to carry their interference full as far as is expedient. The great difficulty here is, to persuade them to confine themselves within bounds. A thousand little passions and prejudices have led them to narrow the liberty of the subject in this line, in cases in which the punishment is either attended with no profit at all, or with none that will make up for the expense.

XVII. The mischief of this sort of interference is more particularly conspicuous in the article of religion. The reasoning, in this case, is of the following stamp. There are certain errors, in matters of belief, to which all mankind are prone: and for these errors in judgment, it is the determination of a Being of infinite benevolence, to punish them with an infinity of torments. But from these errors the legislator himself is necessarily free: for the men, who happen to be at hand for him to consult with, being men perfectly enlightened, unfettered, and unbiased, have such advantages over all the rest of the world, that when they sit down to enquire out the truth relative to points so plain and so familiar as those in question, they cannot fail to find it. This being the case, when the sovereign sees his people ready to plunge headlong into an abyss of fire, shall he not stretch out a hand to save them? Such, for example, seems to have been the train of reasoning, and such the motives, which led Lewis the XIVth into those coercive measures which he took for the conversion of heretics and the confirmation of true believers. The groundwork, pure sympathy and loving-kindness: the superstructure, all the miseries which the most determined malevolence could have devised. But of this more fully in another place.

XVIII. The rules of probity are those, which in point of expediency stand most in need of assistance on the part of the legislator, and in which, in point of fact, his interference has been most extensive. There are few cases in which it would be expedient to punish a man for hurting himself: but there are few cases, if any, in which it would not be expedient to punish a man for injuring his neighbour. With regard to that branch of probity which is opposed to offences against property, private ethics depends in a manner for its very existence upon legislation. Legislation must first determine what things are to be regarded as each man's property, before the general rules of ethics, on this head, can have any particular application. The case is the same with regard to offences against the state. Without legislation there would be no such thing as a state: no particular persons invested with powers to be exercised for the benefit of the rest. It is plain, therefore, that in this branch the interference of the legislator cannot any where be dispensed with. We must first know what are the dictates of legislation, before we can know what are the dictates of private ethics.

XIX. As to the rules of beneficence, these, as far as concerns matters of detail, must necessarily be abandoned in great measure to the jurisdiction of private ethics. In many cases the beneficial quality of the act depends essentially upon the disposition of the agent; that is, upon the motive by which he appears to have been prompted to perform it: upon their belonging to the head of sympathy, love of amity, or love of reputation; and not to any head of self-regarding motives. brought into play by the force of political constraint: in a word, upon their being such as denominate his conduct free and voluntary, according to one of the many senses given to those ambiguous expressions. The limits of the law on this head seem, however, to be capable of being extended a good deal farther than they seem ever to have been extended hitherto. In particular, in cases where the person is in danger, why should it not be made the duty of every man to save another from mischief, when it can be done without prejudicing himself, as well as to abstain from bringing it on him? This accordingly is the idea pursued in the body of the work.

XX. To conclude this section, let us recapitulate and bring to a point the difference between private ethics. considered as an art or science, on the one hand, and that branch of jurisprudence which contains the art or science of legislation, on the other. Private ethics teaches how each man may dispose himself to pursue the course most conducive to his own happiness, by means of such motives as offer of themselves: the art of legislation (which may be considered as one branch of the science of jurisprudence) teaches how a multitude of men, composing a community, may be disposed to pursue that course which upon the whole is the most conducive to the happiness of the whole community, by means of motives to be applied by the legislator.

We come now to exhibit the limits between penal and civil jurisprudence. For this purpose it may be of use to give a distinct though summary view of the principal branches into which jurisprudence, considered in its utmost extent, is wont to be divided.

§ 2. Jurisprudence, its branches

XXI. Jurisprudence is a fictitious entity: nor can any meaning be found for the word, but by placing it in company with some word that shall be significative of a real entity. To know what is meant by jurisprudence, we must know, for example, what is meant by a book of jurisprudence. A book of jurisprudence can have but one or the other of two objects: In the former case it may be styled a book of expository jurisprudence; in the latter, a book of censorial jurisprudence: or, in other words, a book on the art of legislation.
 * 1) To ascertain what the law is:
 * 2) to ascertain what it ought to be.

XXII. A book of expository jurisprudence, is either authoritative or unauthoritative. It is styled authoritative, when it is composed by him who, by representing the state of the law to be so and so, causeth it so to be; that is, of the legislator himself: unauthoritative, when it is the work of any other person at large.

XXIII. Now law, or the law, taken indefinitely, is an abstract and collective term; which, when it means any thing, can mean neither more nor less than the sum total of a number of individual laws taken together. It follows, that of whatever other modifications the subject of a book of jurisprudence is susceptible, they must all of them be taken from some circumstance or other of which such individual laws, or the assemblages into which they may be sorted, are susceptible. The circumstances that have given rise to the principal branches of jurisprudence we are wont to hear of, seem to be as follows:
 * 1) The extent of the laws in question in point of dominion.
 * 2) The political quality of the persons whose conduct they undertake to regulate.
 * 3) The time of their being in force.
 * 4) The manner in which they are expressed.
 * 5) The concern which they have with the article of punishment

XXIV. In the first place, in point of extent, what is delivered concerning the laws in question, may have reference either to the laws of such or such a nation or nations in particular, or to the laws of all nations whatsoever: in the first case, the book may be said to relate to local, in the other, to universal jurisprudence.

Now of the infinite variety of nations there are upon the earth, there are no two which agree exactly in their laws: certainly not in the whole: perhaps not even in any single article: and let them agree today, they would disagree tomorrow. This is evident enough with regard to the substance of the laws: and it would be still more extraordinary if they agreed in point of form; that is, if they were conceived in precisely the same strings of words. What is more, as the languages of nations are commonly different, as well as their laws, it is seldom that, strictly speaking, they have so much as a single word in common. However, among the words that are appropriated to the subject of law, there are some that in all languages are pretty exactly correspondent to one another: which comes to the same thing nearly as if they were the same. Of this stamp, for example, are those which correspond to the words power, right, obligation, liberty, and many others.

It follows, that if there are any books which can, properly speaking, be styled books of universal jurisprudence, they must be looked for within very narrow limits. Among such as are expository, there can be none that are authoritative: nor even, as far as the substance of the laws is concerned, any that are unauthoritative. To be susceptible of an universal application, all that a book of the expository kind can have to treat of, is the import of words: to be, strictly speaking, universal, it must confine itself to terminology. Accordingly the definitions which there has been occasion here and there to intersperse in the course of the present work, and particularly the definition hereafter given of the word law, may be considered as matter belonging to the head of universal jurisprudence. Thus far in strictness of speech: though in point of usage, where a man, in laying down what he apprehends to be the law, extends his views to a few of the nations with which his own is most connected, it is common enough to consider what he writes as relating to universal jurisprudence.

It is in the censorial line that there is the greatest room for disquisitions that apply to the circumstances of all nations alike: and in this line what regards the substance of the laws in question is as susceptible of an universal application, as what regards the words. That the laws of all nations, or even of any two nations, should coincide in all points, would be as ineligible as it is impossible: some leading points, however, there seem to be, in respect of which the laws of all civilized nations might, without inconvenience, be the same. To mark out some of these points will, as far as it goes, be the business of the body of this work.

XXV. In the second place, with regard to the political quality of the persons whose conduct is the object of the law. These may, on any given occasion, be considered either as members of the same state, or as members of different states: in the first ease, the law may be referred to the head of internal, in the second case, to that of international jurisprudence.

Now as to any transactions which may take place between individuals who are subjects of different states, these are regulated by the internal laws, and decided upon by the internal tribunals, of the one or the other of those states: the case is the same where the sovereign of the one has any immediate transactions with a private member of the other: the sovereign reducing himself, pro re natâ, to the condition of a private person, as often as he submits his cause to either tribunal; whether by claiming a benefit, or defending himself against a burthen. There remain then the mutual transactions between sovereigns, as such, for the subject of that branch of jurisprudence which may be properly and exclusively termed international.

With what degree of propriety rules for the conduct of persons of this description can come under the appellation of laws, is a question that must rest till the nature of the thing called a law shall have been more particularly unfolded.

It is evident enough, that international jurisprudence may, as well as internal, be censorial as well as expository, unauthoritative as well as authoritative.

XXVI. Internal jurisprudence, again, may either concern all the members of a state indiscriminately, or such of them only as are connected in the way of residence, or otherwise, with a particular district. Jurisprudence is accordingly sometimes distinguished into national and provincial. But as the epithet provincial is hardly applicable to districts so small as many of those which have laws of their own are wont to be, such as towns, parishes, and manors; the term local (where universal jurisprudence is plainly out of the question) or the term particular, though this latter is not very characteristic, might either of them be more commodious.

XXVII. Thirdly, with respect to time. In a work of the expository kind, the laws that are in question may either be such as are still in force at the time when the book is writing, or such as have ceased to be in force. In the latter case the subject of it might be termed ancient; in the former, present or living jurisprudence: that is, if the substantive jurisprudence, and no other, must at any rate be employed, and that with an epithet in both cases. But the truth is, that a book of the former kind is rather a book of history than a book of jurisprudence; and, if the word jurisprudence be expressive of the subject, it is only with some such words as history or antiquities prefixed. And as the laws which are any where in question are supposed, if nothing appears to the contrary, to be those which are in force, no such epithet as that of present or living commonly appears.

Where a book is so circumstanced, that the laws which form the subject of it, though in force at the time of its being written, are in force no longer, that book is neither a book of living jurisprudence, nor a book on the history of jurisprudence: it is no longer the former, and it never was the latter. It is evident that, owing to the changes which from time to time must take place, in a greater or less degree, in every body of laws, every book of jurisprudence, which is of an expository nature, must in the course of a few years, come to partake more or less of this condition.

The most common and most useful object of a history of jurisprudence, is to exhibit the circumstances that have attended the establishment of laws actually in force. But the exposition of the dead laws which have been superseded, is inseparably interwoven with that of the living ones which have superseded them. The great use of both these branches of science, is to furnish examples for the art of legislation.

XXVIII. Fourthly, in point of expression, the laws in question may subsist either in the form of statute or in that of customary law. As to the difference between these two branches (which respects only the article of form or expression) it cannot properly be made appear till some progress has been made in the definition of a law.

XXIX. Lastly, The most intricate distinction of all, and that which comes most frequently on the carpet, is that which is made between the civil branch of jurisprudence and the penal, which latter is wont, in certain circumstances, to receive the name of criminal.

What is a penal code of laws? What a civil code? Of what nature are their contents? Is it that there are two sorts of laws, the one penal the other civil, so that the laws in a penal code are all penal laws, while the laws in a civil code are all civil laws? Or is it, that in every law there is some matter which is of a penal nature, and which therefore belongs to the penal code; and at the same time other matter which is of a civil nature, and which therefore belongs to the civil code? Or is it, that some laws belong to one code or the other exclusively, while others are divided between the two? To answer these questions in any manner that shall be tolerably satisfactory, it will be necessary to ascertain what a law is; meaning one entire but single law: and what are the parts into which a law, as such, is capable of being distinguished: or, in other words, to ascertain what the properties are that are to be found in every object which can with propriety receive the appellation of a law. This then will be the business of the third and fourth sections: what concerns the import of the word criminal, as applied to law, will be discussed separately in the fifth.
