“A commonwealth is said to be instituted when a multitude of men do agree, and covenant, every one with every one, that to whatsoever man, or assembly of men, shall be given by the major part the right to present the person of them all, that is to say, to be their representative; every one, as well he that voted for it as he that voted against it, shall authorize all the actions and judgements of that man, or assembly of men, in the same manner as if they were his own, to the end to live peaceably amongst themselves, and be protected against other men.”
