"There are certain books in the world which every searcher for truth must know: the Bible, the Critique of Pure Reason, the Origin of Species, and Karl Marx's Capital"
About this Quote
Capp’s intent is less about endorsing the quartet than about skewering the idea that truth comes with a tidy, compulsory curriculum. The phrase “must know” is doing the satirical work: it mimics the confident moral certainty of gatekeepers who treat their preferred texts as a passport to legitimacy. Coming from a popular cartoonist, the line carries an extra barb. Capp is both outsider and insider to American intellectual culture: he benefits from mass audiences while needling the high-minded posture of “searchers for truth” who perform seriousness through citations.
The subtext is cultural triangulation. Mention the Bible and you signal traditional authority; Kant flatters the philosophy crowd; Darwin needles religious literalism; Marx triggers the era’s political anxieties. Capp forces these constituencies into the same room, then watches them squirm. The quote works because it’s a compressed culture war: it turns a supposedly noble quest into a checklist that reveals what Americans were actually fighting over - who gets to define reality, and which book gets to sit on top of the stack.
