The right of property includes then, the freedom of acquiring by contract. The right of each to what he has produced, implies a right to what has been produced by others, if obtained by their free consent; since the producers must either have given it from good will, or exchanged it for what they esteemed an equivalent, and to prevent them from doing so would be to infringe their right of property in the product of their own industry.
§ 2. Before proceeding to consider the things which the principle of individual property does not include, we must specify one more thing which it does include: and this is that a title, after a certain period, should be given by prescription. According to the fundamental idea of property, indeed, nothing ought to be treated as such, which has been acquired by force or fraud, or appropriated in ignorance of a prior title vested in some other person; but it is necessary to the security of rightful possessors, that they should not be molested by charges of wrongful acquisition, when by the lapse of time witnesses must have perished or been lost sight of, and the real character of the transaction can no longer be cleared up. Possession which has not been legally questioned within a moderate number of years, ought to be, as by the laws of all nations it is, a complete title. Even when the acquisition was wrongful, the dispossession, after a generation has elapsed, of the probably bonâ fide possessors, by the revival of a claim which had been long dormant, would generally be a greater injustice, and almost always a greater private and public mischief, than leaving the original wrong without atonement. It may seem hard that a claim, originally just, should be defeated by mere lapse of time; but there is a time after which (even looking at the individual case, and without regard to the general effect on the security of possessors), the balance of hardship turns the other way. With the injustices of men, as with the convulsions and disasters of nature, the longer they remain unrepaired, the greater become the ob-
