 Boolos is puzzled why we overlook these clear counterexamples. One explanation is that we tend to treat the induction step as a generic generalization such as ‘People have ten toes’(Sorensen 2012) rather than a generalization with a quantifier such as ‘all’ or ‘most’. Whereas the universal generalization ‘All people have ten toes’ is refuted by a single person with eleven toes, the generic generalization tolerates exceptions.
