"It cannot be precisely known how any thing is good or bad, till it is precisely known what it is"
About this Quote
The intent is procedural discipline. Mill is warning that “good” and “bad” are not free-floating labels you can slap on whatever scares or seduces you. They’re conclusions that depend on prior clarity about the object itself: its parts, its causes, its effects, its boundaries. Without that, moral language becomes theater - passionate, persuasive, and fundamentally unaccountable.
The subtext is a quiet attack on inherited dogma and rhetorical shortcuts. In Mill’s era, public arguments about religion, political reform, and emerging industrial life were saturated with big words (“virtue,” “corruption,” “rights”) that often concealed muddled definitions. Mill’s suspicion is that many moral disputes aren’t really about values; they’re about people using the same word to mean different things, then calling the confusion a fight over principle.
Context matters: James Mill, a historian and key voice in British utilitarian circles (and father of John Stuart Mill), helped build an intellectual culture that treated society as something you could analyze, not merely revere. This line reads like a foundational rule for that project: before you praise or condemn institutions, policies, even “human nature,” specify what you’re talking about. Precision isn’t pedantry here; it’s the price of honest judgment.
