 It has been argued, however, that there are some difficulties with Maritain’s position here. For example, even if it is true that people may ‘naturally’ affirm the proposition that there is a God, it is not obvious how they can claim that they know it. In other words, even if the proposition is true, it is not clear how we can say that we know or believe it to be true. What Maritain seems to give us here is an explanation of how one arrives at a certain proposition and of one’s certainty, but nothing more. But, since the state of certainty of an individual is not the same as the assertion that that person knows something to be true, it is not clear that the pre-philosophical approach provides one with an adequate basis to say that a religious belief is true, only that one is convinced of it. And, one might argue, parallel conclusions can be drawn if one examines the other ways that Maritain suggests will lead to a putative knowledge of God.
