Abstract
Traditionally, knowledge of God has been considered to arise from two sources: our innate human capacities of reason and intuition, and special divine revelation. The former is the subject of natural theology and the latter of systematic or dogmatic theology. In this article I argue that this rigid distinction should be dispensed with, both because of the need to respond to the criticisms of atheists that religious beliefs are not grounded on evidence, and because different religions make different and contradictory claims to truth. Thus, what is purported to be revelation needs to be evaluated on commonly accepted criteria of rationality. Such criteria will exclude both a priori religious assumptions, so as to avoid circularity, and a priori atheistic assumptions, so as to avoid excluding what is being investigated by fiat. The project of evaluating specific Christian claims in this way, such as the resurrection of Jesus, is what has been dubbed “ramified natural theology.”
