To make an act which causes death murder, then, the actor ought, on principle, to know, or have notice of the facts which make the act dangerous. There are certain exceptions to this principle which will be stated presently, but they have less application to murder than to some smaller statutory crimes. The general rule prevails for the most part in murder.

But furthermore, on the same principle, the danger which in fact exists under the known circ.u.mstances ought to be of a cla.s.s which a man of reasonable prudence could foresee. Ignorance of a fact and inability to foresee a consequence have the same effect on blameworthiness. If a consequence cannot be foreseen, it cannot be avoided. But there is this practical difference, that whereas, in most cases, the question of knowledge is a question of the actual condition of the defendant's consciousness, the question of what he might have foreseen is determined by the standard of the prudent man, that is, by general experience. For it is to be remembered that the object of the law is to prevent human life being endangered or taken; and that, although it so far considers blameworthiness in punishing as not to hold a man responsible for consequences which [57] no one, or only some exceptional specialist, could have foreseen, still the reason for this limitation is simply to make a rule which is not too hard for the average member of the community. As the purpose is to compel men to abstain from dangerous conduct, and not merely to restrain them from evil inclinations, the law requires them at their peril to know the teachings of common experience, just as it requires them to know the law. Subject to these explanations, it may be said that the test of murder is the degree of danger to life attending the act under the known circ.u.mstances of the case. /1/

It needs no further explanation to show that, when the particular defendant does for any reason foresee what an ordinary man of reasonable prudence would not have foreseen, the ground of exemption no longer applies. A harmful act is only excused on the ground that the party neither did foresee, nor could with proper care have foreseen harm.

It would seem, at first sight, that the above a.n.a.lysis ought to exhaust the whole subject of murder. But it does not without some further explanation. If a man forcibly resists an officer lawfully making an arrest, and kills him, knowing him to be an officer, it may be murder, although no act is done which, but for his official function, would be criminal at all. So, if a man does an act with intent to commit a felony, and thereby accidentally kills another; for instance, if he fires at chickens, intending to steal them, and accidentally kills the owner, whom he does not see. Such a case as this last seems hardly to be reconcilable with the general principles which have been laid down. It has been argued somewhat as [58] follows:--The only blameworthy act is firing at the chickens, knowing them to belong to another. It is neither more nor less so because an accident happens afterwards; and hitting a man, whose presence could not have been suspected, is an accident. The fact that the shooting is felonious does not make it any more likely to kill people. If the object of the rule is to prevent such accidents, it should make accidental killing with firearms murder, not accidental killing in the effort to steal; while, if its object is to prevent stealing, it would do better to hang one thief in every thousand by lot.

Still, the law is intelligible as it stands. The general test of murder is the degree of danger attending the acts under the known state of facts. If certain acts are regarded as peculiarly dangerous under certain circ.u.mstances, a legislator may make them punishable if done under these circ.u.mstances, although the danger was not generally known. The law often takes this step, although it does not nowadays often inflict death in such cases. It sometimes goes even further, and requires a man to find out present facts, as well as to foresee future harm, at his peril, although they are not such as would necessarily be inferred from the facts known.

Thus it is a statutory offence in England to abduct a girl under sixteen from the possession of the person having lawful charge of her. If a man does acts which induce a girl under sixteen to leave her parents, he is not chargeable, if he had no reason to know that she was under the lawful charge of her parents, /1/ and it may be presumed that he would not be, if he had reasonable cause to believe that she was a boy. But if he knowingly abducts a girl from [59] her parents, he must find out her age at his peril. It is no defence that he had every reason to think her over sixteen. /1/ So, under a prohibitory liquor law, it has been held that, if a man sells "Plantation Bitters," it is no defence that he does not know them to be intoxicating. /2/ And there are other examples of the same kind.

Now, if experience shows, or is deemed by the law-maker to show, that somehow or other deaths which the evidence makes accidental happen disproportionately often in connection with other felonies, or with resistance to officers, or if on any other ground of policy it is deemed desirable to make special efforts for the prevention of such deaths, the lawmaker may consistently treat acts which, under the known circ.u.mstances, are felonious, or const.i.tute resistance to officers, as having a sufficiently dangerous tendency to be put under a special ban. The law may, therefore, throw on the actor the peril, not only of the consequences foreseen by him, but also of consequences which, although not predicted by common experience, the legislator apprehends. I do not, however, mean to argue that the rules under discussion arose on the above reasoning, any more than that they are right, or would be generally applied in this country.

Returning to the main line of thought it will be instructive to consider the relation of manslaughter to murder. One great difference between the two will be found to lie in the degree of danger attaching to the act in the given state of facts. If a man strikes another with a small stick which is not likely to kill, and which he has no reason to suppose will do more than slight bodily harm, but which [60] does kill the other, he commits manslaughter, not murder. /1/ But if the blow is struck as hard as possible with an iron bar an inch thick, it is murder. /2/ So if, at the time of striking with a switch, the party knows an additional fact, by reason of which he foresees that death will be the consequence of a slight blow, as, for instance, that the other has heart disease, the offence is equally murder. /3/ To explode a barrel of gunpowder in a crowded street, and kill people, is murder, although the actor hopes that no such harm will be done. /4/ But to kill a man by careless riding in the same street would commonly be manslaughter. /5/ Perhaps, however, a case could be put where the riding was so manifestly dangerous that it would be murder.

To recur to an example which has been used already for another purpose: "When a workman flings down a stone or piece of timber into the street, and kills a man; this may be either misadventure, manslaughter, or murder, according to the circ.u.mstances under which the original act was done: if it were in a country village, where few pa.s.sengers are, and he calls out to all people to have a care, it is misadventure only; but if it were in London, or other populous town, where people are continually pa.s.sing, it is manslaughter, though he gives loud warning; and murder, if he knows of their pa.s.sing, and gives no warning at all." /6/

The law of manslaughter contains another doctrine [61] which should be referred to in order to complete the understanding of the general principles of the criminal law. This doctrine is, that provocation may reduce an offence which would otherwise have been murder to manslaughter. According to current morality, a man is not so much to blame for an act done under the disturbance of great excitement, caused by a wrong done to himself, as when he is calm. The law is made to govern men through their motives, and it must, therefore, take their mental const.i.tution into account.

It might be urged, on the other side, that, if the object of punishment is prevention, the heaviest punishment should be threatened where the strongest motive is needed to restrain; and primitive legislation seems sometimes to have gone on that principle. But if any threat will restrain a man in a pa.s.sion, a threat of less than death will be sufficient, and therefore the extreme penalty has been thought excessive.

At the same time the objective nature of legal standards is shown even here. The mitigation does not come from the fact that the defendant was beside himself with rage. It is not enough that he had grounds which would have had the same effect on every man of his standing and education. The most insulting words are not provocation, although to this day, and still more when the law was established, many people would rather die than suffer them without action. There must be provocation sufficient to justify the pa.s.sion, and the law decides on general considerations what provocations are sufficient.

It is said that even what the law admits to be "provocation does not extenuate the guilt of homicide, unless the person provoked is at the time when he does the deed [62] deprived of the power of self-control by the provocation which he has received." /1/ There are obvious reasons for taking the actual state of the defendant's consciousness into account to this extent. The only ground for not applying the general rule is, that the defendant was in such a state that he could not be expected to remember or be influenced by the fear of punishment; if he could be, the ground of exception disappears. Yet even here, rightly or wrongly, the law has gone far in the direction of adopting external tests. The courts seem to have decided between murder and manslaughter on such grounds as the nature of the weapon used, /2/ or the length of time between the provocation and the act. /3/ But in other cases the question whether the prisoner was deprived of self-control by pa.s.sion has been left to the jury.

/4/

As the object of this Lecture is not to give an outline of the criminal law, but to explain its general theory, I shall only consider such offences as throw some special light upon the subject, and shall treat of those in such order as seems best fitted for that purpose. It will now be useful to take up malicious mischief, and to compare the malice required to const.i.tute that offence with the malice aforethought of murder.

The charge of malice aforethought in an indictment for murder has been shown not to mean a state of the defendant's mind, as is often thought, except in the sense that he knew circ.u.mstances which did in fact make his conduct dangerous. It is, in truth, an allegation like that of negligence, which a.s.serts that the party accused did not [63] come up to the legal standard of action under the circ.u.mstances in which he found himself, and also that there was no exceptional fact or excuse present which took the case out of the general rule. It is an averment of a conclusion of law which is permitted to abridge the facts (positive and negative) on which it is founded.

When a statute punishes the "wilfully and maliciously" injuring another's property, it is arguable, if not clear, that something more is meant. The presumption that the second word was not added without some meaning is seconded by the unreasonableness of making every wilful trespa.s.s criminal. /1/ If this reasoning prevails, maliciously is here used in its popular sense, and imports that the motive for the defendant's act was a wish to harm the owner of the property, or the thing itself, if living, as an end, and for the sake of the harm. Malice in this sense has nothing in common with the malice of murder.

Statutory law need not profess to be consistent with itself, or with the theory adopted by judicial decisions. Hence there is strictly no need to reconcile such a statute with the principles which have been explained. But there is no inconsistency.

Although punishment must be confined to compelling external conformity to a rule of conduct, so far that it can always be avoided by avoiding or doing certain acts as required, with whatever intent or for whatever motive, still the prohibited conduct may not be hurtful unless it is accompanied by a particular state of feeling.

Common disputes about property are satisfactorily settled by compensation. But every one knows that sometimes secret harm is done by neighbor to neighbor out of [64] pure malice and spite.

The damage can be paid for, but the malignity calls for revenge, and the difficulty of detecting the authors of such wrongs, which are always done secretly, affords a ground for punishment, even if revenge is thought insufficient.

How far the law will go in this direction it is hard to say. The crime of arson is defined to be the malicious and wilful burning of the house of another man, and is generally discussed in close connection with malicious mischief. It has been thought that the burning was not malicious where a prisoner set fire to his prison, not from a desire to consume the building, but solely to effect his escape. But it seems to be the better opinion that this is arson, /1/ in which case an intentional burning is malicious within the meaning of the rule. When we remember that arson was the subject of one of the old appeals which take us far back into the early law, /2/ we may readily understand that only intentional burnings were redressed in that way. /3/ The appeal of arson was brother to the appeal de pace et plagis. As the latter was founded on a warlike a.s.sault, the former supposed a house-firing for robbery or revenge, /4/ such as that by which Njal perished in the Icelandic Saga. But this crime seems to have had the same history as others. As soon as intent is admitted to be sufficient, the law is on the high-road to an external standard. A man who intentionally sets fire to his own house, which is so near to other houses that the fire will manifestly endanger them, is guilty of arson if one of the other houses is burned in consequence. /5/ In this case, an act which would not [65] have been arson, taking only its immediate consequences into account, becomes arson by reason of more remote consequences which were manifestly likely to follow, whether they were actually intended or not. If that may be the effect of setting fire to things which a man has a right to burn, so far as they alone are concerned, why, on principle, should it not be the effect of any other act which is equally likely under the surrounding circ.u.mstances to cause the same harm. /1/ Cases may easily be imagined where firing a gun, or making a chemical mixture, or piling up oiled rags, or twenty other things, might be manifestly dangerous in the highest degree and actually lead to a conflagration. If, in such cases, the crime is held to have been committed, an external standard is reached, and the a.n.a.lysis which has been made of murder applies here.

There is another cla.s.s of cases in which intent plays an important part, for quite different reasons from those which have been offered to account for the law of malicious mischief. The most obvious examples of this cla.s.s are criminal attempts.

Attempt and intent, of course, are two distinct things. Intent to commit a crime is not itself criminal. There is no law against a man's intending to commit a murder the day after tomorrow. The law only deals with conduct. An attempt is an overt act. It differs from the attempted crime in this, that the act has failed to bring about the result which would have given it the character of the princ.i.p.al crime. If an attempt to murder results in death within a year and a day, it is murder. If an attempt to steal results in carrying off the owner's goods, it is larceny.

If an act is done of which the natural and probable [66] effect under the circ.u.mstances is the accomplishment of a substantive crime, the criminal law, while it may properly enough moderate the severity of punishment if the act has not that effect in the particular case, can hardly abstain altogether from punishing it, on any theory. It has been argued that an actual intent is all that can give the act a criminal character in such instances. /1/ But if the views which I have advanced as to murder and manslaughter are sound, the same principles ought logically to determine the criminality of acts in general. Acts should be judged by their tendency under the known circ.u.mstances, not by the actual intent which accompanies them.

It may be true that in the region of attempts, as elsewhere, the law began with cases of actual intent, as those cases are the most obvious ones. But it cannot stop with them, unless it attaches more importance to the etymological meaning of the word attempt than to the general principles of punishment. Accordingly there is at least color of authority for the proposition that an act is punishable as an attempt, if, supposing it to have produced its natural and probable effect, it would have amounted to a substantive crime. /2/

But such acts are not the only punishable attempts. There is another cla.s.s in which actual intent is clearly necessary, and the existence of this cla.s.s as well as the name (attempt) no doubt tends to affect the whole doctrine. Some acts may be attempts or misdemeanors which [67] could not have effected the crime unless followed by other acts on the part of the wrong-doer. For instance, lighting a match with intent to set fire to a haystack has been held to amount to a criminal attempt to burn it, although the defendant blew out the match on seeing that he was watched. /1/ So the purchase of dies for making counterfeit coin is a misdemeanor, although of course the coin would not be counterfeited unless the dies were used. /2/

In such cases the law goes on a new principle, different from that governing most substantive crimes. The reason for punishing any act must generally be to prevent some harm which is foreseen as likely to follow that act under the circ.u.mstances in which it is done. In most substantive crimes the ground on which that likelihood stands is the common working of natural causes as shown by experience. But when an act is punished the natural effect of which is not harmful under the circ.u.mstances, that ground alone will not suffice. The probability does not exist unless there are grounds for expecting that the act done will be followed by other acts in connection with which its effect will be harmful, although not so otherwise. But as in fact no such acts have followed, it cannot, in general, be a.s.sumed, from the mere doing of what has been done, that they would have followed if the actor had not been interrupted. They would not have followed it unless the actor had chosen, and the only way generally available to show that he would have chosen to do them is by showing that he intended to do them when he did what he did. The accompanying intent in that case renders the otherwise [68] innocent act harmful, because it raises a probability that it will be followed by such other acts and events as will all together result in harm. The importance of the intent is not to show that the act was wicked, but to show that it was likely to be followed by hurtful consequences.

It will be readily seen that there are limits to this kind of liability. The law does not punish every act which is done with the intent to bring about a crime. If a man starts from Boston to Cambridge for the purpose of committing a murder when he gets there, but is stopped by the draw and goes home, he is no more punishable than if he had sat in his chair and resolved to shoot somebody, but on second thoughts had given up the notion. On the other hand, a slave who ran after a white woman, but desisted before he caught her, has been convicted of an attempt to commit rape. /1/ We have seen what amounts to an attempt to burn a haystack; but it was said in the same case, that, if the defendant had gone no further than to buy a box of matches for the purpose, he would not have been liable.

Eminent judges have been puzzled where to draw the line, or even to state the principle on which it should be drawn, between the two sets of cases. But the principle is believed to be similar to that on which all other lines are drawn by the law. Public policy, that is to say, legislative considerations, are at the bottom of the matter; the considerations being, in this case, the nearness of the danger, the greatness of the harm, and the degree of apprehension felt. When a man buys matches to fire a haystack, or starts on a journey meaning to murder at the end of it, there is still a considerable chance that he will [69] change his mind before he comes to the point. But when he has struck the match, or c.o.c.ked and aimed the pistol, there is very little chance that he will not persist to the end, and the danger becomes so great that the law steps in. With an object which could not be used innocently, the point of intervention might be put further back, as in the case of the purchase of a die for coining.

The degree of apprehension may affect the decision, as well as the degree of probability that the crime will be accomplished. No doubt the fears peculiar to a slaveowning community had their share in the conviction which has just been mentioned.

There is one doubtful point which should not be pa.s.sed over. It has been thought that to shoot at a block of wood thinking it to be a man is not an attempt to murder, /1/ and that to put a hand into an empty pocket, intending to pick it, is not an attempt to commit larceny, although on the latter question there is a difference of opinion. /2/ The reason given is, that an act which could not have effected the crime if the actor had been allowed to follow it up to all results to which in the nature of things it could have led, cannot be an attempt to commit that crime when interrupted. At some point or other, of course, the law must adopt this conclusion, unless it goes on the theory of retribution for guilt, and not of prevention of harm.

But even to prevent harm effectually it will not do to be too exact. I do not suppose that firing a pistol at a man with intent to kill him is any the less an attempt to murder because the bullet misses its aim. Yet there the act has produced the whole effect possible to it in the [70] course of nature. It is just as impossible that that bullet under those circ.u.mstances should hit that man, as to pick an empty pocket. But there is no difficulty in saying that such an act under such circ.u.mstances is so dangerous, so far as the possibility of human foresight is concerned, that it should be punished. No one can absolutely know, though many would be pretty sure, exactly where the bullet will strike; and if the harm is done, it is a very great harm. If a man fires at a block, no harm can possibly ensue, and no theft can be committed in an empty pocket, besides that the harm of successful theft is less than that of murder. Yet it might be said that even such things as these should be punished, in order to make discouragement broad enough and easy to understand.

There remain to be considered certain substantive crimes, which differ in very important ways from murder and the like, and for the explanation of which the foregoing a.n.a.lysis of intent in criminal attempts and a.n.a.logous misdemeanors will be found of service.

The type of these is larceny. Under this name acts are punished which of themselves would not be sufficient to accomplish the evil which the law seeks to prevent, and which are treated as equally criminal, whether the evil has been accomplished or not.

Murder, manslaughter, and arson, on the other hand, are not committed unless the evil is accomplished, and they all consist of acts the tendency of which under the surrounding circ.u.mstances is to hurt or destroy person or property by the mere working of natural laws.

In larceny the consequences immediately flowing from the act are generally exhausted with little or no harm to the owner. Goods are removed from his possession by [71] trespa.s.s, and that is all, when the crime is complete. But they must be permanently kept from him before the harm is done which the law seeks to prevent. A momentary loss of possession is not what has been guarded against with such severe penalties. What the law means to prevent is the loss of it wholly and forever, as is shown by the fact that it is not larceny to take for a temporary use without intending to deprive the owner of his property. If then the law punishes the mere act of taking, it punishes an act which will not of itself produce the evil effect sought to be prevented, and punishes it before that effect has in any way come to pa.s.s.

The reason is plain enough. The law cannot wait until the property has been used up or destroyed in other hands than the owner's, or until the owner has died, in order to make sure that the harm which it seeks to prevent has been done. And for the same reason it cannot confine itself to acts likely to do that harm. For the harm of permanent loss of property will not follow from the act of taking, but only from the series of acts which const.i.tute removing and keeping the property after it has been taken. After these preliminaries, the bearing of intent upon the crime is easily seen.

According to Mr. Bishop, larceny is "the taking and removing, by trespa.s.s, of personal property which the trespa.s.ser knows to belong either generally or specially to another, with the intent to deprive such owner of his ownership therein; and perhaps it should be added, for the sake of some advantage to the trespa.s.ser, a proposition on which the decisions are not harmonious." /1/

There must be an intent to deprive such owner of his [72]

ownership therein, it is said. But why? Is it because the law is more anxious not to put a man in prison for stealing unless he is actually wicked, than it is not to hang him for killing another?

That can hardly be. The true answer is, that the intent is an index to the external event which probably would have happened, and that, if the law is to punish at all, it must, in this case, go on probabilities, not on accomplished facts. The a.n.a.logy to the manner of dealing with attempts is plain. Theft may be called an attempt to permanently deprive a man of his property, which is punished with the same severity whether successful or not. If theft can rightly be considered in this way, intent must play the same part as in other attempts. An act which does not fully accomplish the prohibited result may be made wrongful by evidence that but for some interference it would have been followed by other acts co-ordinated with it to produce that result. This can only be shown by showing intent. In theft the intent to deprive the owner of his property establishes that the thief would have retained, or would not have taken steps to restore, the stolen goods. Nor would it matter that the thief afterwards changed his mind and returned the goods. From the point of view of attempt, the crime was already complete when the property was carried off.

It may be objected to this view, that, if intent is only a makeshift which from a practical necessity takes the place of actual deprivation, it ought not to be required where the actual deprivation is wholly accomplished, provided the same criminal act produces the whole effect. Suppose, for instance, that by one and the same motion a man seizes and backs another's horse over a precipice. The whole evil which the law seeks to prevent is the natural and manifestly [73] certain consequence of the act under the known circ.u.mstances. In such a case, if the law of larceny is consistent with the theories here maintained, the act should be pa.s.sed upon according to its tendency, and the actual intent of the wrong-doer not in any way considered. Yet it is possible, to say the least, that even in such a case the intent would make all the difference. I a.s.sume that the act was without excuse and wrongful, and that it would have amounted to larceny, if done for the purpose of depriving the owner of his horse. Nevertheless, if it was done for the sake of an experiment, and without actual foresight of the destruction, or evil design against the owner, the trespa.s.ser might not be held a thief.

The inconsistency, if there is one, seems to be explained by the way in which the law has grown. The distinctions of the common law as to theft are not those of a broad theory of legislation; they are highly technical, and very largely dependent upon history for explanation. /1/

The type of theft is taking to one's own user It used to be, and sometimes still is, thought that the taking must be lucri catesa, for the sake of some advantage to the thief. In such cases the owner is deprived of his property by the thief's keeping it, not by its destruction, and the permanence of his loss can only be judged of beforehand by the intent to keep. The intent is therefore always necessary, and it is naturally stated in the form of a self-regarding intent. It was an advance on the old precedents when it was decided that the intent to deprive the owner of his property was sufficient. As late as 1815 the English judges stood only six to five in favor of the proposition [74]

that it was larceny to take a horse intending to kill it for no other purpose than to destroy evidence against a friend. /1/ Even that case, however, did not do away with the universality of intent as a test, for the destruction followed the taking, and it is an ancient rule that the criminality of the act must be determined by the state of things at the time of the taking, and not afterwards. Whether the law of larceny would follow what seems to be the general principle of criminal law, or would be held back by tradition, could only be decided by a case like that supposed above, where the same act accomplishes both taking and destruction. As has been suggested already, tradition might very possibly prevail.

Another crime in which the peculiarities noticed in larceny are still more clearly marked, and at the same time more easily explained, is burglary. It is defined as breaking and entering any dwelling-house by night with intent to commit a felony therein. /2/ The object of punishing such a breaking and entering is not to prevent trespa.s.ses, even when committed by night, but only such trespa.s.ses as are the first step to wrongs of a greater magnitude, like robbery or murder. /3/ In this case the function of intent when proved appears more clearly than in theft, but it is precisely similar. It is an index to the probability of certain future acts which the law seeks to prevent. And here the law gives evidence that this is the true explanation. For if the apprehended act did follow, then it is no longer necessary to allege that the breaking and entering was with that intent. An indictment for burglary which charges that [75] the defendant broke into a dwelling-house and stole certain property, is just as good as one which alleges that he broke in with intent to steal. /1/

It is believed that enough has now been said to explain the general theory of criminal liability, as it stands at common law.

The result may be summed up as follows. All acts are indifferent per se.

In the characteristic type of substantive crime acts are rendered criminal because they are done finder circ.u.mstances in which they will probably cause some harm which the law seeks to prevent.

The test of criminality in such cases is the degree of danger shown by experience to attend that act under those circ.u.mstances.

In such cases the mens rea, or actual wickedness of the party, is wholly unnecessary, and all reference to the state of his consciousness is misleading if it means anything more than that the circ.u.mstances in connection with which the tendency of his act is judged are the circ.u.mstances known to him. Even the requirement of knowledge is subject to certain limitations. A man must find out at his peril things which a reasonable and prudent man would have inferred from the things actually known. In some cases, especially of statutory crimes, he must go even further, and, when he knows certain facts, must find out at his peril whether the other facts are present which would make the act criminal. A man who abducts a girl from her parents in England must find out at his peril whether she is under sixteen.

[76] In some cases it may be that the consequence of the act, under the circ.u.mstances, must be actually foreseen, if it is a consequence which a prudent man would not have foreseen. The reference to the prudent man, as a standard, is the only form in which blameworthiness as such is an element of crime, and what would be blameworthy in such a man is an element;--first, as a survival of true moral standards; second, because to punish what would not be blameworthy in an average member of the community would be to enforce a standard which was indefensible theoretically, and which practically was too high for that community.

In some cases, actual malice or intent, in the common meaning of those words, is an element in crime. But it will be found that, when it is so, it is because the act when done maliciously is followed by harm which would not have followed the act alone, or because the intent raises a strong probability that an act, innocent in itself, will be followed by other acts or events in connection with which it will accomplish the result sought to be prevented by the law.
