"In all intellectual debates, both sides tend to be correct in what they affirm, and wrong in what they deny"
About this Quote
The intent isn’t mushy centrism; it’s epistemic discipline. Mill is writing in a 19th-century Britain roiled by reform, religious doubt, industrial upheaval, and a press culture that could turn ideas into factions overnight. In that context, his liberal project in On Liberty and related work depends on a social technology: keep arguments in circulation, because any side that stops listening starts hallucinating its own completeness. The “affirm/deny” structure is surgical. Affirmation is usually bounded - you can defend a partial truth from experience, evidence, or coherent values. Denial is where overreach blooms: you start claiming the other side has nothing, that their premises are not just incomplete but illegitimate.
Subtext: most debates are not binary; they’re competing spotlights. Each side illuminates different parts of the room and then insists the shadows are empty. Mill’s wager is that progress comes less from humiliating opponents than from forcing your own view to survive contact with theirs. The sentence is also a quiet warning to reformers and traditionalists alike: your righteousness is most dangerous at the moment you feel most logically armed.
