[76] In some cases it may be that the consequence of the act, under the circumstances, 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. [77] LECTURE III. -- TORTS.--TRESPASS AND NEGLIGENCE. The object of the next two Lectures is to discover whether there is any common ground at the bottom of all liability in tort, and if so, what that ground is. Supposing the attempt to succeed, it will reveal the general principle of civil liability at common law. The liabilities incurred by way of contract are more or less expressly fixed by the agreement of the parties concerned, but those arising from a tort are independent of any previous consent of the wrong-doer to bear the loss occasioned by his act. If A fails to pay a certain sum on a certain day, or to deliver a lecture on a certain night, after having made a binding promise to do so, the damages which he has to pay are recovered in accordance with his consent that some or all of the harms which may be caused by his failure shall fall upon him. But when A assaults or slanders his neighbor, or converts his neighbor's property, he does a harm which he has never consented to bear, and if the law makes him pay for it, the reason for doing so must be found in some general view of the conduct which every one may fairly expect and demand from every other, whether that other has agreed to it or not.
