My primary interest, reflected in my dissertation, is the metaphysics and philosophical theology of G.W. Leibniz. In general I argue that Leibniz’s adherence to the doctrine of divine concurrence is consistent with other tenets of his metaphysical system, particularly his account of perfections and substantial simplicity. In fact his account of concurrence mirrors closely that of his Scholastic predecessor, Francisco Suarez (pictured above). See the abstract.



Leibniz & Philosophical


In a current article, I attend to

Leibniz’s reading of the imago dei doctrine, arguing that the strength of his reading of the doctrine far surpasses that of previous philosophers, including that of St. Thomas Aquinas. I compare Leibniz and St. Thomas on the basis of the latter’s criterion for resemblance conditions, concluding that Leibniz favors a likeness between God and creature that hinges on matters of degree and not kind.  (Under Review)

Other Work

Bertrand Russell’s early work on Leibniz’s philosophy is chock-full of interesting analyses. One concerns Russell’s reading of Leibniz on substance, which the former takes to have ramifications for other accounts of substance (e.g., that of F.H. Bradley).  See my article “The Early Russell on the Metaphysics of Substance in Leibniz & Bradley” in Synthese (July 2008).



Leibniz & Metaphysics 

In another article, I present an account of the simplicity of Leibnizian substances by appeal to a truthmaker formulation of metaphysical predication. If, as Leibniz suggests, individual substances are entirely simple, then the attribution of causal powers (and to some extent, modal states) becomes problematic for substantial simplicity. I attempt to forestall the problematic consequences by setting out a truthmaker formulation of predication that is consistent with Leibniz’s pronouncements on the matter.
