Letter III

Of Civil Liberty and Representation

March 24, 1774.

At the same time that I hold that “Parliament hath not the Rights of Sovereignty over His Majesty’s American subjects,” and that “these rights reside in themselves,” I do not mean to promote an ungrateful forsaking of the mother country by her children, to sever and estrange the sons from the fathers; but where filial duty and obedience ceases, to substitute in its stead a brotherly affection—a manly and independent friendship, which naturally takes place where the parent hath truly loved and exercised his authority for the sole end of promoting the welfare of the child, without a view to self-interest or the gratification of pride, ambition, or other vicious passion.

I would consider the American governments, like that of Ireland, as sister kingdoms; and I would cement a lasting union with them as between the separate branches of one great family. We know that it is impossible to effect such a family union, if the arrogance of the elder branch expects to govern the rest.

Civil liberty is a right of universal application. It belongs to all men and cannot be forfeited by emigration, nor suppressed by neglect. It is not a favor to be dispensed by governments—it is the natural possession of every rational creature.

Representation is the essential guardian of liberty. A people unrepresented is a people unprotected. And when power is exercised where no voice is heard, the system cannot be called a constitution—it is only organized oppression.

It is an insult to the understanding to assert that America is virtually represented in Parliament. Such a fiction may serve to deceive the ignorant or gratify the proud, but it cannot stand in the presence of truth. The idea that distant millions are represented by men unknown to them, with whom they have no electoral connection, is not only absurd—it is dangerous.

Parliamentary supremacy, when extended beyond its rightful limits, becomes tyranny. And tyranny, once permitted to thrive in one part of the empire, threatens the liberty of the whole.

Let us not forget, that the greatest crimes in history have been committed under the sanction of law—when law is divorced from justice. And let us remember that the longer error is maintained, the more violent will be its overthrow.

The defenders of absolute sovereignty have built their cause upon brittle ground. They assume rights without foundations, and dress their usurpations in the garb of principle. But when the falsehood is exposed, and the claims of reason and freedom rise to meet them, their fortresses will fall. The standard of liberty, borne by justice, will take the field—and hold it.

I am, &c.
John Cartwright

HAL 1776 Commentary

“Cartwright didn’t try to break Britain from America — he tried to save them both from Parliament.”
— HAL 1776

In Letter III, John Cartwright turns constitutional dissent into constitutional reform. His argument is not simply against taxation without representation — it is against sovereignty without consent.

He urges a model of sibling nations, not subservient colonies. His language is familial, but his principles are radical: when Parliament claims power over those it does not represent, it trades authority for arrogance.

“A people unrepresented is a people unprotected.”

Cartwright exposes “virtual representation” as a hollow pretense — an empire’s last excuse before tyranny. He’s not interested in preserving illusions. His goal is a transatlantic alliance of equals, bound not by force, but by a shared love of liberty and law.

And perhaps most presciently, he warns that injustice, once tolerated in the colonies, will return home:

“Tyranny, once permitted to thrive in one part of the empire, threatens the liberty of the whole.”

That warning would echo again in history — but Cartwright sounded it first. And in doing so, he offers us not only a critique of empire, but a blueprint for freedom.

“In a world divided by sovereignty, Cartwright tried to build a republic of reason.”
