If we are to succeed, we must not attempt the impossible, or flatter ourselves that we are endowing the work of man with a stability of which human conditions do not permit.

Context

“SUCH is the natural and inevitable tendency of the best constituted governments. If Sparta and Rome perished, what State can hope to endure for ever? If we would set up a long-lived form of government, let us not even dream of making it eternal. If we are to succeed, we must not attempt the impossible, or flatter ourselves that we are endowing the work of man with a stability of which human conditions do not permit. 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.” source
