Of all these forms of government, the matter being mortal, so that not only monarchs but also whole assemblies die, it is necessary, for the conservation of the peace of men, that as there was order taken for an artificial man, so there be order also taken for an artificial eternity of life: without which, men that are governed by an assembly should return into the condition of war in every age; and they that are governed by one man, as soon as their governor dieth. This artificial eternity is that which men call the right of “succession.”
There is no perfect form of government where the disposing of the succession is not in the present sovereign. For if it be in any other particular man or private assembly, it is in a person subject, and may be assumed by the sovereign at his pleasure; and consequently the right is in himself. And if it be in no particular man, but left to a new choice, then is the commonwealth dissolved, and the right is in him that can get it; contrary to the intention of them that did institute the commonwealth, for their perpetual, and not temporary security.
