"He who refuses to do arithmetic is doomed to talk nonsense"
About this Quote
As a politician, McCarthy is staking out a particular kind of authority: the legitimacy of numbers in an arena that routinely rewards vibes, slogans, and selective outrage. The subtext is a rebuke to the rhetorical shortcuts that flourish in campaigns and cable news: big promises without budgets, fear without probabilities, “common sense” without denominators. Arithmetic here stands in for basic quantitative literacy: knowing the difference between millions and billions, understanding rates vs. totals, recognizing that tradeoffs exist. Refusing that literacy isn’t neutral; it’s an invitation to be manipulated or to manipulate others.
The quote also flatters its audience in a strategic way. If you can count, you’re part of the sober, responsible public; if you can’t (or won’t), you’re the mark. That’s a classic political move, but it’s deployed toward a rare end: narrowing the range of acceptable bullshit.
In a culture where “my truth” can outrun measurable facts, McCarthy’s point feels less like technocratic scolding and more like democratic self-defense. Numbers don’t guarantee honesty, but refusing them guarantees nonsense.
