"Man, as a physical being, is like other bodies governed by invariable laws"
About this Quote
That’s not mere scientism; it’s a strategic Enlightenment gambit. In an era still policed by theological certainty and monarchical prestige, insisting on “invariable laws” is a way to relocate authority from altar and throne to observation and reason. It implies that to understand human behavior - including politics - you should look for patterns, constraints, and causal pressures rather than moralizing stories. The subtext is almost prosecutorial: if humans are bodies, then fear, hunger, climate, habit, and institutions shape outcomes as reliably as gravity shapes motion.
Montesquieu’s context matters: he’s a founding figure in thinking about how systems (laws, constitutions, social arrangements) channel behavior. This line underwrites his larger project: politics isn’t a sermon, it’s an engineering problem with human materials. The sting is that “invariable” doesn’t just describe nature; it challenges the flattering idea that power, piety, or charisma can repeal reality.
