Abstract
James V. Schall is well known for being a learned theorist of so-called Christian Aristotelianism. That Schall affirms the basic compatibility of Christian faith and human reason, then, is not surprising. But the particular way that he affirms this is surprising. Schall regularly speaks of the relation of Christian faith and human reason in terms of the qualified incompleteness of both political philosophy and Christian revelation. The mutual incompleteness of political philosophy and Christian revelation indirectly sheds light on the characteristic error made by contemporary hyper-rationalists, whether they are overt modern rationalists or covert religious rationalists.
