De la possibilité à l’existence : Kant critique de Leibniz

This article offers a contribution to the study of Leibniz’s thought on possibility and existence based on a reconstruction of the evolution of Kant’s thought on these notions in Nova dilucidatio (1755), Beweisgrund (1763) and Kritik der reinen Vernunft (1781-1787). Its aim is to shed light on Kant’s debt to Leibniz and to show that only the critical turn could make them diverge on the question of the possibility of existence through a two-fold opposition on epistemology (the role of experience) and ontology (the eclipse of God).
