The Common Law [57]
moral condition of him who inflicts them, so, at the other extreme, it may on grounds of policy throw the absolute risk of certain transactions on the person engaging in them, irrespective of blameworthiness in any sense. Instances of this sort have been mentioned in the last Lecture, /1/ and will be referred to again.
Most liabilities in tort lie between these two extremes, and are founded on the infliction of harm which the defendant had a reasonable opportunity to avoid at the time of the acts or omissions which were its proximate cause. Rut as fast as specific rules are worked out in place of the [146] vague reference to the conduct of the average man, they range themselves alongside of other specific rules based on public policy, and the grounds from which they spring cease to be manifest. So that, as will be seen directly, rules which seem to lie outside of culpability in any sense have sometimes been referred to remote fault, while others which started from the general notion of negligence may with equal ease be referred to some extrinsic ground of policy.
Apart from the extremes just mentioned, it is now easy to see how the point at which a man's conduct begins to be at his own peril is generally fixed. When the principle is understood on which that point is determined by the law of torts, we possess a common ground of classification, and a key to the whole subject, so far as tradition has not swerved the law from a consistent theory. It has been made pretty clear from what precedes, that I find that ground in knowledge of circumstances accompanying an act or conduct indifferent but for those circumstances.
But it is worth remarking, before that criterion is discussed, that a possible common ground is reached at the preceding step in the descent from malice through intent and foresight. Foresight is a possible common denominator of wrongs at the two extremes of malice and negligence. The purpose of the law is to prevent or secure a man indemnity from harm at the hands of his neighbors, so far as consistent with other considerations which have been mentioned, and excepting, of course, such harm as it permits to be intentionally inflicted. When a man foresees that harm will result from his conduct, the principle which exonerates him from accident no longer applies, and he is liable. But, as has been shown, he is bound to foresee [147] whatever a prudent and intelligent man would have foreseen, and therefore he is liable for conduct from which such a man would have foreseen that harm was liable to follow.
Accordingly, it would be possible to state all cases of negligence in terms of imputed or presumed foresight. It would be possible even to press the presumption further, applying the very inaccurate maxim, that every man is presumed to intend the natural consequences of his own acts; and this mode of expression will, in fact, be found to have been occasionally used, /1/ more especially in the criminal law, where the notion of intent has a stronger foothold. /2/ The latter fiction is more remote and less philosophical than the former; but, after all, both are equally fictions. Negligence is not foresight, but precisely the want of it; and if foresight were presumed, the ground of the presumption, and therefore the essential element, would be the knowledge of facts which made foresight possible.
Taking knowledge, then, as the true starting-point, the next question is how to determine the circumstances necessary to be known in any given case in order to make a man liable for the consequences of his act. They must be such as would have led a prudent man to perceive danger, although not necessarily to foresee the specific harm. But this is a vague test. How is it decided what those circumstances are? The answer must be, by experience.
But there is one point which has been left ambiguous in the preceding Lecture and here, and which must be touched upon. It has been assumed that conduct which [148] the man of ordinary intelligence would perceive to be dangerous under the circumstances, would be blameworthy
