To assess the merits and demerits of the content of Culp’s educational programme, the paper does three things: First, it discusses whether Culp’s defence against conceivable objections manages to effectively dispel the charge of cosmopolitan arrogance. Second, it spells out one implication of epistemic modesty, which Culp considers a core competence to be imparted by citizenship education. Third, it reflects upon the tricky task of motivating individuals to comply with the demands of justice. Taken together, the paper argues that Culp’s case is impressively strong but nevertheless tends to suffer from a rationalist constriction. It does not leave sufficient room for tradition in private life and public reasoning. This rationalist constriction is problematic from a normative philosophical, and especially a practice-oriented viewpoint.
