Text: Dutch and Rembrandt's cheerful Self-Portrait with a Toque, his beloved Hendrickje Stoffels, also portrayed nude in Bathsheba Bathing; Van Dyck's gracious, dignified Charles I of England; among the scores of Rubens, his tenderly personal Helena Fourment; Jordaens' Four Evangelists as diligent Dutchmen.
Entailment: The self portrait displays the Rembrandt naked.
Contradiction: The Dutchmen were not diligent people.
