L’expression de « théologie pratique » donne une clé de l’interprétation que faisait René Marlé de sa propre pratique de la théologie, telle qu’il l’a mise en œuvre notamment à l’Institut Supérieur de Pastorale Catéchétique de Paris et dans ses inlassables contributions au mouvement catéchétique. C’est aussi un clé de l’unité de sa vie de croyant, de savant et de formateur.Articulée sur une approche herméneutique, confrontée aux rationalités modernes d’un côté, et sur une analyse des pratiques, familière des sciences humaines (...) d’autre part, cette pratique théologique, pleine de pudeur, alliait le souci pédagogique de la formation des esprits et de la transmission du savoir aux recherches les plus aiguës sur les problèmes contemporains de la foi.The expression “practical theology” is a key to the interpretation that René Marlé made of his own practice of theology. He did it, especially, at the Institut Supérieur de Pastorale Catéchétique de Paris and in his untiring contributions to the catechetical movement. It is also a key to the unity of his life as a believer, savant and teacher.On the one hand, his work was articulated with a hermeneutical approach and confronted modern rationalities. On the other hand, he analysed experience and was familiar with the human sciences. This theological work, full of modesty, brought together a pedagogical concern for the formation of minds and, from very careful research, the transmission of knowledge to contemporary problems of faith.

There are two accounts of the relation between subject and predicate in Leibniz's writings. The former, which appears in De arte combinatoria, is based on an interpretation of this relation in terms of sum and parts and can be viewed as an anticipation of mereology. The latter, which operates after 1686, is based on an interpretation of this relation in terms of inherence. Metaphysical reasons, linked with the discovery of infinitesimal calculus, explain this shift.
