Article I. All men are born free and equal, and have certain natural, essential, and unalienable rights; among which may be reckoned the right of enjoying and defending their lives and liberties; that of acquiring, possessing, and protecting property; in fine, that of seeking and obtaining their safety and happiness. 1790 Constitution of the State of Massachusetts.
The quote is correct, but that is the 1780 Constitution of Massachusetts, framed at a convention which met at Boston, September 1, 1779.
my mistake, thanks
