 With the support of the apostolic vicar in China, Malebranche published in 1708 an Entretien d’un philosophe chrétien et d’un philosophe chinois, sur l’existence et la nature de Dieu (Dialogue between a Christian Philosopher and a Chinese Philosopher on the Existence and Nature of God). A sixth and last edition of the Recherche appeared in 1712, and in 1715 Malebranche published his final work, Réflexions sur la prémotion physique (Reflections on Physical Premotion), in which he responded to the claim of the abbé Laurent-François Boursier (1679–1749) that occasionalism leads naturally to the Thomistic position that God determines our action by means of a “physical premotion.” In his response, Malebranche defended the claim, present from the first edition of the Recherche, that our free action involves a “consent” that God does not determine.
