"I don't say. 'Let us represent Christ as Aslan.' I say, 'Supposing there was a world like Narnia, and supposing, like ours, it needed redemption, let us imagine what sort of Incarnation and Passion and Resurrection Christ would have there.'" -- C.S. LewisThis is all well and good, but for two things:
- Within the context of the supposal, there are story elements which ARE allegorical, and where a one-to-one mapping succeeds. Thus, there are allegories within the overarching story. A book need not be a cover-to-cover allegory in order to CONTAIN allegories.
- The lay reader won't know a supposal from a suppository. Any review written for lay readers must use colloquial terminology, pedantic ire notwithstanding. Hence I say "allegory."
