"When the legislative and executive powers are united in the same person, or in the same body of magistrates, there can be no liberty; because apprehensions may arise, lest the same monarch or senate should enact tyrannical laws, to execute them in a tyrannical manner"
About this Quote
The subtext is distrust of concentrated virtue. Montesquieu doesn’t need to prove a monarch will become a tyrant; he only has to point out that the architecture makes tyranny efficient. If lawmakers can also execute, they can tailor laws to their own enforcement power, then apply them “in a tyrannical manner” without institutional resistance. That final repetition of “tyrannical” is doing work: it suggests a closed loop where the injustice is baked in at creation and intensified at application.
Context matters. Writing in the long shadow of French absolutism and watching England’s post-Glorious Revolution settlement, Montesquieu is translating a political moment into a portable rule. His intent isn’t just separation of powers as etiquette; it’s separation as an antidote to self-dealing. Liberty survives, in this view, not because rulers are enlightened, but because they are forced to negotiate with rival powers.

Evidence: When the legislative and executive powers are united in the same person, or in the same body of magistrates, there can be no liberty; because apprehensions may arise, lest the same monarch or senate should enact tyrannical laws, to execute them in a tyrannical manner. (Book XI, Chapter 6 ("Of the Constitution of England")). Primary source is Montesquieu’s De l’esprit des lois (commonly translated as The Spirit of Laws), first published in French in 1748. The quoted English wording is the standard translation that appears in Book XI, Chapter 6 (often titled "Of the Constitution of England"). An English translation by Thomas Nugent is commonly dated 1750; later editions/revisions exist, so the exact English publication year depends on the edition, but the original first publication of the work containing the passage is 1748 in French.
