Ese párrafo está en el §168 del Segundo Tratado sobre el Gobierno Civil - John Locke, 1689. Es donde pasa de "derecho" a "deber" de rebelarse contra la tiranía:

Texto original inglés §168 - "Of Tyranny"

"But if a long train of abuses, prevarications and artifices, all tending the same way, make the design visible to the people, and they cannot but feel what they lie under, and see whither they are going; it is not to be wondered, that they should then rouse themselves, and endeavour to put the rule into such hands which may secure to them the ends for which government was at first erected; and without which, ancient names, and specious forms, are so far from being better, that they are much worse, than the state of nature, or pure anarchy; the inconveniencies being all as great and as near, but the remedy farther off and more difficult. And it is not only their right, but their duty to do it. For as they are all made equal in the state of nature, and consequently have all a right to the preservation of themselves and the rest of mankind, so no man can be subjected to the arbitrary power of another, without his own consent; and no man can be supposed to consent to be subjected to the arbitrary power of another, to the prejudice of his life, liberty, or estate. When therefore any one shall go about to bring them into such a slavish condition, they will always have a right to preserve what they have not a power to part with; and to rid themselves of those who invade this fundamental, sacred, and unalterable law of self-preservation, for which they entered into society."

Traducción literal de la parte clave

"Y no es sólo su derecho, sino su deber hacerlo. Pues como todos son hechos iguales en el estado de naturaleza, y en consecuencia todos tienen derecho a la preservación de sí mismos y del resto de la humanidad, ningún hombre puede ser sometido al poder arbitrario de otro sin su propio consentimiento; y no puede suponerse que ningún hombre consienta ser sometido al poder arbitrario de otro, en perjuicio de su vida, libertad o bienes. Por tanto, cuando alguien intente llevarlos a tal condición de esclavitud, siempre tendrán derecho a preservar lo que no tienen poder para ceder; y a librarse de quienes invaden esta ley fundamental, sagrada e inalterable de la autoconservación, por la cual entraron en sociedad."

Jefferson lo copió casi literal en la Declaración de Independencia 1776

"But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security."

Resumen en 1 línea: Locke: Si el gobierno te esclaviza, rebelarte no es opción. Es obligación moral. Porque entraste en sociedad para conservar tu vida/libertad, no para regalarla.

Choque brutal con hoy:
Locke 1689: "Deber de librarse del tirano"
Código Penal 2026 art.472: "Rebelión = 15-25 años cárcel"

Para Locke, el art.472 sería tiránico y nulo por "ley injusta no es ley" de Tomás.
