 Arnauld interrupted his work on the Réflexions to write the Dissertation, which was published in 1685 together with the first chapter of Book Three of the Reflexions, a chapter dealing with Malebranche’s position that Jesus Christ, in his human nature, is the occasional cause of the distribution of grace. Arnauld raises theological objections to both positions, but also attacks the underlying occasionalism. The Dissertation touched off a rapid series of replies and ounter-replies in 1685. The first volume of Reflexions was published later in 1685, and the second and third volumes in 1686.
