Quel statut donner aux calculs et surtout aux figures proposées par Henri Bergson pour expliquer le fonctionnement de la reconnaissance dans Matière et mémoire ? Ce travail suggère que ces calculs et ces figures ne sont pas que des métaphores commodes ; la réalité n'est pas dépourvue d'un certain nombre d’éléments et de grandeurs plus ou moins importantes. Il semble donc possible de supposer qu'après avoir arithmétisé les faits de conscience à l'aide de nombres spéciaux (dans l’Essai), Bergson géométrise l’être spirituel et matériel (dans Matière et mémoire).

Le but de cet article est de proposer un examen de l’ontologie matérielle de Franz Brentano. Nous soutenons ici la thèse selon laquelle Brentano défend un type original de monisme. Ce monisme peut être vu comme la conjonction de trois théories : le réisme (la thèse selon laquelle il n’existe que des choses individuelles concrètes), le monisme de priorité (la thèse selon laquelle il n’y a qu’une seule substance) et le super-substantialisme (la thèse selon laquelle cette substance est l’espace).

In the Traité des systèmes, Condillac analyses a plurality of systematic metaphysical doctrines, specifically, those of Spinoza, Malebranche and Leibniz. Commentators have mainly interpreted this plurality as a way for Condillac to illustrate his criticisms and to raise doubts about the main contemporary systems while using the same criteria for interpretation. However, I note that his analytic tools differ according to which philosopher or philosophical system he analyses. This paper focuses on the criticism of Leibniz’s system, and aims to show that Condillac operated from subsequent reconstructions. In order to raise criticisms against the Leibnizian system, Condillac gave it an architectonic structure that is borrowed mainly from Wolff.

In this paper, I demonstrate the pivotal function of consciousness in the second part of Phenomenology of Perception. A new meaning of the notion avoids the alternative between empiricism and intellectualism that gives this second part its structure. Consciousness, bogged down with the world, is neither only a state, nor only an act; in other words, it conveys life, conceived by Merleau-Ponty as a ‘living’ and a ‘making.’ Thus, it has a metaphysical dimension that renders it irreducible to experience. Consciousness, which I show is both ‘original’ and ‘philosophical,’ corresponds to an effective comprehension of contradiction in everything.

This paper is devoted to a fundamental aspect of Diderot’s materialist philosophy: the fact that psychological identity does not exactly correspond with the material individuals we are because the memories on which psychological identity relies are always partial. This is complicated by the fact that even the material individual is denied reality since, as is stated in the Rêve de d’Alembert, the only individual is the «whole». By relating these two approaches, I try to show how one can develop a theory of the individual that takes into account the gap between individuation as a physical process and the constitution of a psychological individual.

In this article, I examine the standard assumption that ethical disagreements on abortion and human embryonic stem cells research are grounded on metaphysical claims that underlie these ethical issues. Contrary to what some philosophers have claimed, I argue that, although the bioethical positions about the human embryo’s moral status are partly grounded on metaphysical claims, incorporating metaphysical arguments in the debates about the ethics of reproduction will not resolve this issue.

In this article, I examine two aspects of the transition from Kant to Fichte: systematicity and the primacy of practical reason. It is commonly agreed that Kant saw the critical exercise as an occasion to renew, rather than supress, the possibility of a positive metaphysics; however, most scholars now consider the “system” he sketched to be the sole heritage of Schulmetaphysik. However, I take literally Kant’s demand for a system that expects from the “practical” a new and absolute “foundation,” rather than a system that must be completed. Here, Fichte’s perspective gives us the common thread.

Jean-Luc Marion’s phenomenology reveals two attitudes regarding the classification of phenomena. On the one hand, they are classified by type. On the other, the “banality of saturation” reduces these types to possible interpretations, in which case saturation isn’t a qualitative rupture anymore, but a possible hermeneutic attitude to any phenomenon. Hence, there is, in Marion’s phenomenology, a tension between a metaphysical attitude that maintains categorial discontinuities, and a hermeneutic temptation driven by the recovery of quantitative continuities between all phenomena. Yet, Marion does not push this quantitative temptation to its limits; he steps back in front of a specifically saturated phenomenon: the icon.
