Each generation is as independent as the one preceding, as that was of all which had gone before. It has then, like them, a right to choose for itself the form of government it believes most promotive of its own happiness; consequently, to accommodate to the circumstances in which it finds itself, that received from its predecessors; and it is for the peace and good of mankind, that a solemn opportunity of doing this every nineteen or twenty years, should be provided by the constitution; so that it may be handed on, with periodical repairs, from generation to generation, to the end of time, if anything human can so long endure.
