I agree with Paul directionally, but I think he could have gone further – and perhaps he has since – so I compare his view to my own in a Substack article. I’m not sure whether he’d disagree with the extensions. Check it out.
Most grand moral theories assume a degree of conceptual stability that moral language has never possessed.
Aristotle’s aretĂŞ, Kant’s maxims, Mill’s utilities, Rawls’s ‘reasonable rejection’ – pick your passion/poison. Each one presupposes that a concept has a single, portable meaning that obligingly follows philosophers from ancient Greece to medieval Christendom to your local ethics seminar. It doesn’t. It never did. We’ve merely been pretending it does in order to keep the theoretical architecture standing.
Drawing on conceptual genealogy, philosophy of language, and cross-cultural moral psychology, I argue that the universalist ambitions of virtue ethics, deontology, consequentialism, and contractualism collapse not because their logic is flawed, but because their vocabulary evaporates the moment you ask it to do heavy lifting. Our moral terms drift, fracture, mutate, and occasionally reinvent themselves altogether. Yet moral theorists continue to legislate universal principles as if the words were obedient little soldiers rather than unruly historical artefacts.
This isn’t a manifesto for relativism – quite the opposite. It is a call for modesty: an acknowledgement that moral frameworks function as context-bound heuristics, exquisitely useful within particular forms of life but laughably overextended when dressed up as timeless moral law.
If the Language Insufficiency Hypothesis has taught me anything, it’s that once you stop bullying language into behaving like mathematics, you begin to see moral philosophy for what it is – a set of imaginative tools, not an ontology of obligation.
Read it, disagree with it, file it under ‘Why Bry insists on burning down the Enlightenment one paper at a time’ – your choice. But at least now the argument exists in the world, properly dressed and indexed, ready to irritate anyone still clinging to the dream of universal moral principles.
