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 circumstances 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 analysis 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 circumstances, a legislator may make them punishable if done under these circumstances, 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 circumstances, are felonious, or constitute 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 circumstances under which the original act was done: if it were in a country village, where few passengers 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 passing, it is manslaughter, though he gives loud warning; and murder, if he knows of their passing, 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 constitution 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 passion, 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 passion, 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
