The final chapter addresses the question of what Kant should have said in reply to Constant’s challenge. The objections of his readers and interpreters should be taken seriously as expressions of ordinary moral consciousness; and it is true that moral restrictions can leave us feel helpless in the face of evil. But these considerations would not have been sufficient to change Kant’s mind. So, should his rigorous opposition to untruthfulness count against his moral philosophy? It is argued that Kant’s absolutism is less problematic than it seems, partly because most – if not all – realistic reconstructions of Constant’s case leave us with more promising practical options than lying, partly because Kant’s moral theory contains certain resources that mitigate his absolutism, for example, his conception of the Highest Good. The question of whether his ethical prohibition of lying as a violation of a duty to self is justified is left unanswered.
