"Incommensurables cannot be compared"
About this Quote
Hardin’s line reads like a math truism, but it’s really a cultural warning shot aimed at the modern itch to rank everything. “Incommensurables cannot be compared” is a refusal of the comforting fiction that every value can be translated into a single currency: dollars, lives saved, acres protected, “utility.” Hardin spent his career circling the problem that public debates treat trade-offs as if they were clean, commensurate, spreadsheet-friendly choices, when they’re often clashes between entirely different moral systems.
The intent is defensive and strategic. If two things are incommensurable, then the usual political move - demand “proof,” force a cost-benefit analysis, insist on measurable outcomes - becomes a kind of sleight of hand. Hardin is saying: stop pretending the argument is technical when it’s actually ethical. In environmental conflicts, that matters. A wetland is not just “ecosystem services”; a species is not just “genetic information”; a community’s way of life is not just “economic activity.” Once you accept those translations uncritically, you’ve already conceded the fight to whoever controls the metric.
The subtext has teeth: comparison is power. The moment you agree on a common measure, you hand the debate to the institutions that can quantify, monetize, and administrate. Hardin’s broader context - scarcity, carrying capacity, and the political tragedies that follow - makes the sentence feel less like abstraction and more like a constraint: some choices can’t be optimized, only owned. The quote works because it forces a reader to confront the unglamorous truth beneath policy rhetoric: not every conflict has a neat conversion rate.
