Abstract
This critical study of De Dijn's work is divided into three parts; in the first, theauthor briefly presents his own point of view and refers to the notion of the disenchantment of the world developed by M. Weber and M. Gauchet. In the second, he tries to reconstruct De Dijn's vision and dwells on his use of the notion of fidelity to a tradition and on his recurrent but metaphoric use of Christian theological words. In the third,the author asks some critical questions, as for instance about De Dijrís conception of the life-world; about his strategy aiming at positing some values or realities as sacred and at immunizing the tradition against critiques which could undermine its coherenceand unity; about De Dijn's mistrust of such technological developments as medically assisted child conception or discoveries which could lead to the radical transformation ofthe human body
