"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.
