We find in Pascal a double approach to the moral issue. On the one hand the author of the Pensées strongly criticizes the moral ideals of philosophy, in particular those of Stoicism but, on the other, he claims that there is a "true morals" which "mocks of morals". We here analyze this double approach from the point of view of four contexts exhibited in the Pensées: 1- The epistemological context that distinguishes the "esprit de géométrie" and the "esprit de finesse" which points, respectively, to a "moral of the ' esprit'" and to a "moral of judgment". 2- The anthropological context of the "disproportion of men" and of virtue as mean 3- The anthropological-theological context of the misery and greatness of man. 4- The metaphysical-theological context of the theory of the "three orders of things". The "true morals" is construed in two movements. In the first, Pascal's morals is naturalistic and shares the mechanism of his time. In the second, it is theological and emerges essentially as an hermeneutics of desire.
