"Discussion is an exchange of knowledge; an argument an exchange of ignorance"
About this Quote
The subtext is less about manners than about incentives. In a real exchange of knowledge, you risk being changed by what you hear; your position is provisional. In an argument, the goal is victory, not accuracy, so ignorance isn’t a lack of facts so much as a refusal to update. Quillen’s sting is in the symmetry: both are “exchanges,” both are social rituals, but only one has a learning agenda. The other merely circulates the same misconceptions at higher volume.
Context matters: Quillen wrote in an era when newspapers were the main mass platform and polemics were a profitable genre. His line reads like a newsroom rule-of-thumb about public life: conflict grabs attention, but it rarely clarifies anything. It also anticipates today’s attention economy, where “argument” is content and “discussion” is labor. The quip survives because it’s not idealistic; it’s diagnostic. It names the moment a conversation stops being about reality and becomes about identity.
