However useful, or even necessary, the stability of possession may be to human society, 'tis attended with very considerable inconveniences. The relation of fitness or suitableness ought never to enter into consideration, in distributing the properties of mankind; but we must govern ourselves by rules which are more general in their application, and more free from doubt and uncertainty. Of this kind is _present_ possession upon the first establishment of society; and afterwards _occupation, prescription, accession_, and _succession_. As these depend very much on chance, they must frequently prove contradictory both to men's wants and desires; and persons and possessions must often be very ill adjusted. This is a grand inconvenience, which calls for a remedy. To apply one directly, and allow every man to seize by violence what he judges to be fit for him, would destroy society; and therefore the rules of justice seek some medium betwixt a rigid stability and this changeable and uncertain adjustment. But there is no medium better than that obvious one, that possession and property should always be stable, except when the proprietor consents to bestow them on some other person. This rule can have no ill consequence in occasioning wars and dissensions, since the proprietor's consent, who alone is concerned, is taken along in the alienation; and it may serve to many good purposes in adjusting property to persons. Different parts of the earth produce different commodities; and not only so, but different men both are by nature fitted for different employments, and attain to greater perfection in any one, when they confine themselves to it alone. All this requires a mutual exchange and commerce; for which reason the translation of property by consent is founded on a law of nature, as well as its stability without such a consent.
