The constitution of man is the work of nature; that of the State the work of art. It is not in men's power to prolong their own lives; but it is for them to prolong as much as possible the life of the State, by giving it the best possible constitution.

Context

“The body politic, as well as the human body, begins to die as soon as it is born, and carries in itself the causes of its destruction. But both may have a constitution that is more or less robust and suited to preserve them a longer or a shorter time. The constitution of man is the work of nature; that of the State the work of art. It is not in men's power to prolong their own lives; but it is for them to prolong as much as possible the life of the State, by giving it the best possible constitution. The best constituted State will have an end; but it will end later than any other, unless some unforeseen accident brings about its untimely destruction.
The life-principle of the body politic lies in the sovereign authority.” source
