 Steven Nadler cites this text while arguing that Arnauld was an “occasionalist” both about the causation of sensory perceptions by bodies, and about the causation of voluntary movements by the human mind (Nadler 1995, 138). Nadler recognizes that Arnauld had quite different attitudes toward the two cases, but nevertheless says that Arnauld “alone among Cartesians” recognized mind-body interaction as a specific problem in Descartes’ metaphysics, and “used an occasionalist solution” (Nadler 1995, 144).
