Luc Ferry is a bestselling author. His L'homme-Dieu ou le Sens de la vie (Grasset, 1996) has appealed to many, including Christians. This induces the A. first to sketch an analysis of the book before critically appraising its implications. He points out an evident ambiguity, already in the title, where the expression man-God is diverted from its Christian meaning and only indicates man's move to selftranscendance. This ambiguity is again found in Ferry's idea of revelation: the illegitimate act of an extrinsic authority which intrudes in the immanence of reason. The moot point is, in fact, Ferry's hermeneutics. However, the article acknowledges his acute sense of the mystery (or of the bounds of reason) which finds expression in his avowal of agnosticism.
