On similar ground it may be proved that no society can make a perpetual constitution, or even a perpetual law. The earth belongs always to the living generation. They may manage it then, & what proceeds from it, as they please, during their usufruct. They are masters too of their own persons, & consequently may govern them as they please. But persons & property make the sum of the objects of government. The constitution and the laws of their predecessors extinguished then in their natural course, with those who gave them being. This could preserve that being till it ceased to be itself, & no longer. Every constitution then, & every law, naturally expires at the end of 19 years. If it be enforced longer, it is an act of force, & not of right. It may be said that the succeeding generation exercising in fact the power of repeal, this leaves them as free as if the constitution or law had been expressly limited to 19 years only.
