The Common Law. Oliver Wendell Holmes

to murder. It is just as much murder to shoot a sentry for the purpose of releasing a friend, as to shoot him because you hate him. Malice, in the definition of murder, has not the same meaning as in common speech, and, in view of the considerations just mentioned, it has been thought to mean criminal intention. /1/

      But intent again will be found to resolve itself into two things; foresight that certain consequences will follow from an act, and the wish for those consequences working as a motive which induces the act. The question then is, whether intent, in its turn, cannot be reduced to a lower term. Sir James Stephen's statement shows that it can be, and that knowledge that the act will probably cause death, that is, foresight of the consequences of the act, is enough in murder as in tort.

      For instance, a newly born child is laid naked out of doors, where it must perish as a matter of course. This is none the less murder, that the guilty party would have been very glad to have a stranger find the child and save it. /2/

      But again, What is foresight of consequences? It is a picture of a future state of things called up by knowledge of the present state of things, the future being viewed as standing to the present in the relation of effect to cause. Again, we must seek a reduction to lower terms. If the known present state of things is such that the act done will very certainly cause death, and the probability is a matter of common knowledge, one who does the act, [54] knowing the present state of things, is guilty of murder, and the law will not inquire whether he did actually foresee the consequences or not. The test of foresight is not what this very criminal foresaw, but what a man of reasonable prudence would have foreseen.

      On the other hand, there must be actual present knowledge of the present facts which make an act dangerous. The act is not enough by itself. An act, it is true, imports intention in a certain sense. It is a muscular contraction, and something more. A spasm is not an act. The contraction of the muscles must be willed. And as an adult who is master of himself foresees with mysterious accuracy the outward adjustment which will follow his inward effort, that adjustment may be said to be intended. But the intent necessarily accompanying the act ends there. Nothing would follow from the act except for the environment. All acts, taken apart from their surrounding circumstances, are indifferent to the law. For instance, to crook the forefinger with a certain force is the same act whether the trigger of a pistol is next to it or not. It is only the surrounding circumstances of a pistol loaded and cocked, and of a human being in such relation to it, as to be manifestly likely to be hit, that make the act a wrong. Hence, it is no sufficient foundation for liability, on any sound principle, that the proximate cause of loss was an act.

      The reason for requiring an act is, that an act implies a choice, and that it is felt to be impolitic and unjust to make a man answerable for harm, unless he might have chosen otherwise. But the choice must be made with a chance of contemplating the consequence complained of, or else it has no bearing on responsibility for that consequence. [55] If this were not true, a man might be held answerable for everything which would not have happened but for his choice at some past time. For instance, for having in a fit fallen on a man, which he would not have done had he not chosen to come to the city where he was taken ill.

      All foresight of the future, all choice with regard to any possible consequence of action, depends on what is known at the moment of choosing. An act cannot be wrong, even when done under circumstances in which it will be hurtful, unless those circumstances are or ought to be known. A fear of punishment for causing harm cannot work as a motive, unless the possibility of harm may be foreseen. So far, then, as criminal liability is founded upon wrong-doing in any sense, and so far as the threats and punishments of the law are intended to deter men from bringing about various harmful results, they must be confined to cases where circumstances making the conduct dangerous were known.

      Still, in a more limited way, the same principle applies to knowledge that applies to foresight. It is enough that such circumstances were actually known as would have led a man of common understanding to infer from them the rest of the group making up the present state of things. For instance, if a workman on a house-top at mid-day knows that the space below him is a street in a great city, he knows facts from which a man of common understanding would infer that there were people passing below. He is therefore bound to draw that inference, or, in other words, is chargeable with knowledge of that fact also, whether he draws the inference or not. If then, he throws down a heavy beam into the street, he does an act [56] which a person of ordinary prudence would foresee is likely to cause death, or grievous bodily harm, and he is dealt with as if he foresaw it, whether he does so in fact or not. If a death is caused by the act, he is guilty of murder. /1/ But if the workman has reasonable cause to believe that the space below is a private yard from which every one is excluded, and which is used as a rubbish heap, his act is not blameworthy, and the homicide is a mere misadventure.

      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 circumstances ought to be of a class 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 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
