James Madison

[A]ll power is originally vested in, and consequently derived from, the people. That government is instituted and ought to be exercised for the benefit of the people; which consists in the enjoyment of life and liberty and the right of acquiring property, and generally of pursuing and obtaining happiness and safety. That the people have an indubitable, unalienable, and indefeasible right to reform or change their government whenever it be found adverse or inadequate to the purpose of its institution.
