Abstract: Reluctant to Kant and positivism, ardently Thomist, Claudel nourishes a lively interest in philosophy, as a way for re-Christianising contemporary society. However, his diaries and letters show déception, lack of understanding and disagreement more often than enthousiasm towards his time Christian philosophers. Bergson, Blondel, Mounier and Maritain are for him ennemies as much as allies.
