David Hume,
Treatise of Human Nature/Book 3…
(1739)
“ All men, say they, are born free and equal: Government and superiority can only by establish'd by consent: The consent of men, in establishing government, imposes on them a new obligation, unknown to the laws of nature. Men, therefore, are bound to obey their magistrates, only because they promise it; and if they had not given their word, either expressly or tacitly, to preserve allegiance, it would never have become a part of their moral duty. ”
