Abstract
This text was conceived as a synthetic introduction to the present-day situation of metaphysics and of ontology, to their stakes and their practices in the world and in France, by way of a preamble to the activities of the Atelier de métaphysique et d’ontologie contemporaines [Workshop on Contemporary Metaphysics and Ontology] at the École normale supérieure. It certainly does not claim to replace the more informed and complete works on which it rests, and which are indicated in the bibliography. Nor was it written with the intention of being polemical against whatever conception of metaphysics, even if it goes without saying that the question is approached in a necssarily partisan, though resolutely conciliatory, manner.
