Abstract

Leibniz endorses the world apart doctrine, according to which a substance is that which is independent of all other things except God. However, I will argue that in what appears to be a radical departure from the causal version of the world apart doctrine, Du Châtelet—whose metaphysics appears to be Leibnizian from a distance—embraces the causal connectedness of created substances. I further show that Du Châtelet’s rejection of Leibniz’s claim that a substance is causally independent of all other created substances can be traced back to a more fundamental antiLeibnizian commitment on Du Châtelet’s part concerning the in-principle accessibility of natural (i.e., non-divine) sufficient reasons by finite minds and to her commitment to a causal theory of intentionality.
