Abstract
This paper traces the basic contours of Aquinas’s account of connatural knowledge in order to see what role (if any) connaturality might play in our knowledge of the precepts of the natural law. It engages a dispute between Maritain and Doolan on this topic. After considering what Aquinas means by “connaturality” in general the paper examines the main elements of his view of knowledge by connaturality in particular. I argue that the true doctrine of Aquinas probably lies between Maritain and Doolan’s opposed interpretations. Although it is not the only way of doing so, connaturality or inclination would still seem to be one possible way of knowing the natural law, while the use of reason is another.
