It is well known that the French Cartesian Nicolas Malebranche (1638–1715) was both an occasionalist in metaphysics and a mechanist in physics. He consistently argued that God is the only true caus...

Unlike many of Descartes’s other followers, Pierre-Sylvain Re´gis resists the temptations of occasionalism. By marrying the ontology of mechanism with the causal structure of concurrentism, Re´gis arrives at a novel view that both acknowledges God’s role in natural events and preserves the causal powers of bodies. I set out Re´gis’s position, focusing on his arguments against occasionalism and his responses to Malebranche’s ‘no necessary connection’ and divine concursus arguments.

Descartes's claim that the eternal truths were freely created by God is fraught with interpretive difficulties. The main arguments in the literature are classified as concerning the ontological status or the modalities of possibility and necessity of the eternal truths. The views of the principal defenders of the Creation Doctrine – Robert Desgabets, Pierre Sylvain Régis, and Antoine Le Grand are contrasted with those of Nicolas Malebranche. In clarifying the theological, ontological, and logical terms of the debate we can see (...) that what was at stake was the objectivity and certainty of the truths of mathematics and physics. I conclude by suggesting that this issue might fruitfully be used to clarify the disparate discussions in the contemporary literature. (shrink)

In VI.ii.3 of The Search After Truth Malebranche offers an argument for the view that only God is a cause. Here I defend an interpretation of the argument according to which Malebranche is supposing (quite rightly) that if there is a necessary connection between a cause and its effect, then if creatures were real causes, God's volitions would not be sufficient to bring about their intended effects. I then consider the argument from constant creation that Malebranche offers in Dialogues on (...) Metaphysics and on Religion. If Malebranche holds that God is literally creating things in their entirety at each and every moment, it is difficult to understand how his system could make room for finite substances, and it is difficult to understand how he can allow that finite minds are to be held accountable for what they do. Here I defend a weakened version of the doctrine of constant creation according to which God is constantly creating the modifications of things but is not constantly creating things in their entirety.
