 (Interestingly, Maritain was a critic of a number of arguments proposed in defence of religious belief. He argued that such defenses fail because they do not recognise that there are different types of knowledge, that these different types are hierarchically arranged, and that the methods they employ are, by definition, unsuited to demonstrate certain things. Thus, Maritain holds that while ‘reason’, as “intelligence moving in a progressive way towards its term, the real”, can attain knowledge of God by means of demonstration, if we take ‘reason’ to be a purely discursive method—one which Maritain identifies with the “physical-mathematical sciences” and which he also calls “the ‘reason’ of rationalism” (Antimoderne, 1922: 64, my translation)—it can know or say nothing at all about God. Because reason must be ordered to its object, reason (in this second sense) can neither demonstrate nor even encounter revealed truths.)
