Liberty proved to be the unalienable Right of all Mankind

John Trenchard, London Journal, Saturday, December 30, 1721

SIR, I intend to entertain my readers with dissertations upon liberty, in some of my succeeding letters; and shall, as a preface to that design, endeavour to prove in this, that liberty is the unalienable right of all mankind.

Where the interest of the governors and that of the governed clash, there can be no stated judge between them: To appeal to a foreign power, is to give up the sovereignty; for either side to submit, is to give up the question: And therefore, if they themselves do not amicably determine the dispute between themselves, heaven alone must. In such case, recourse must be had to the first principles of government itself; which being a departure from the state of nature, and a union of many families forming themselves into a political machine for mutual protection and defence, it is evident, that this formed relation can continue no longer than the machine subsists and can act; and when it does not, the individuals must return to their former state again. No constitution can provide against what will happen, when that constitution is dissolved. Government is only an appointment of one or more persons, to do certain actions for the good and emolument of the society; and if the persons thus interested will not act at all, or act contrary to their trust, their power must return of course to those who gave it.
