 Arnauld thought that Malebranche’s position was dangerous, and that if accepted it would have ruinous consequences for the Catholic faith. He was “furious,” as Denis Moreau has aptly said, “and decided to leave nothing standing in a philosophy that clearly frightened him” (Moreau 1999, 240). Here only the general lines of Arnauld’s attack are set forth. First, two pervasive themes in Arnauld’s criticism are described: (1) that Malebranche often did not proceed by the proper method of either philosophy or theology; and (2) that Malebranche speaks of God in anthropomorphic terms, as if He were subject to the limitations of a human  agent.[20]  Then Arnauld’s criticisms of Malebranche’s position that God acts by “general volitions” will be discussed.
