XII. Now he who is answerable for an act, is answerable for all the injurious consequences attending it. Seneca in one of his controversies, treating upon this point, puts the case of a plane-tree set on fire, by which a house was burnt, and he subjoins the following remark, "although the mischief went further than was intended, yet the person doing it was answerable for the WHOLE, as much, as if he had done it by design. For any one that puts his defence upon the plea of UNINTENTIONAL INJURY, ought to have abstained from all mischief whatsoever." When Ariarathes, king of Cappadocia had wantonly obstructed the channel of the river Melas, which discharges itself into the Euphrates, the swell of waters bursting the mounds, the Euphrates rose to such a height, as to occasion excessive damage to the Cappadocians, the Galatians, and the Phrygians. Upon which the decision of the matter being left to the Romans, they imposed upon him a fine of three hundred talents. XIII. XIV. XV. and XVI. But to proceed with other instances of injury, which render the parties committing them liable to repair the losses occasioned thereby. The case of excusable homicide may be alleged as one, wherein the person, who has committed it, is bound to make every reasonable compensation to the family, dependents, and connections of the deceased party, in proportion to the loss, which they have sustained from his death. As Michael the Ephesian in the fifth book of Aristotle's Ethics has observed, that the compensation made to the parents, the wife or children of the deceased is nearly the same as if it could be made to himself. The writer is here speaking of excusable homicide, that is, when the person by whom it is committed, does it not in the immediate discharge of some legal duty. Wherefore if any one, in defending himself, has killed another from whom he might have escaped, though he may have violated the law of charity, yet he has not incurred the penalty of a capital offence. Upon the same principle the person, who has maimed or mutilated another, will be bound to make him a compensation, proportionably to the means of subsistence which he is deprived of by such a calamity. A thief or a robber is bound to restore what has been taken, and to return it with all the improvements it may have acquired, or to make reparation to the owner, in proportion to the gain, which the privation has prevented him from making, or to the actual value of the thing itself. If the thing has been irretrievably consumed, the estimation of damages must be made, according to a medium between the highest and the lowest value. To this class of offences and due reparation may be referred all frauds upon the public revenue, all unjust decisions, or all false evidence, by which states or individuals are injured.
