I think what stands out in this is that we really are all the story-telling apes (is that in The Globe or Darwin's Watch - maybe both ) even if it's in a passive way by being so open to fantasy almost by default. Age doesn't come into it much either - even if you don't subscribe to any faith in particular, everyone seems able to accept talking animals quite readily along with random references to magic which are almost peripheral to the story and so can be treated as unimportant to the central tale by people with little or no knowledge of Pterry's work.
We are the apes who can readily accept the wonderful in it's basic sense, because our minds are wonderful places where chemical and neural magic happens all the time
