As to forbearance, it is an acknowledged point, that when he knows of a delinquency, which he neither forbids nor punishes, when he is both able and bound to do so, he becomes an accessory to the guilt thereof. Cicero, in his speech against Piso, says, "it makes no great difference especially in a consul, whether he harasses the government by moving ruinous laws, and making mischievous speeches, or suffers others to do the same. If a slave has committed a murder with the knowledge of his master, the master becomes answerable for the entire deed, as it was done with his concurrence." But, as we have said before, besides the knowledge of a deed, to constitute a participation in the guilt, the person so knowing it, must possess the power to prevent it. And this is what is meant by the legal phrase, that the knowledge of a crime, when it is ordered to be punished, is taken in the sense of forbearance or connivance, and it is supposed that the person, who ought to have prevented it, did not do so. In this place knowledge implies a concurrence of will, and connivance a concurrence of design. A master therefore is not bound by the act of a slave, who has claimed his freedom, and done any thing in despite of his master, because the knowledge of a crime without ability to prevent it, by disclosure or some other means, cannot be construed into an act of guilt. So parents are bound by the acts of children; but only in cases where they have the children under their authority. On the other hand, altho' by having them in their power, they might have prevented their misconduct, they will not be answerable for it, unless they had a knowledge of it also. For there ought to be a concurrence of knowledge, and forbearance or encouragement to involve any one in the guilt of another's actions; circumstances all of which by a parity of reasoning may be applied to the connection between sovereigns and subjects: a connection founded on principles both of natural and civil law.
