 The second way is an analogue of Lewis’s method of intersection. Perhaps the first way is needed to deal with the case of blatant contradictions, but as Walton notes even this is far from clear. While imagining a contradiction may well not be possible if imagination relies purely on mental imagery, the kind of imagining invoked in fiction is very different: what is at stake here is propositional imagining and it is difficult to motivate the claim that imagining even blatant contradictions is impossible. Attempts to do so tend to rest on quite contentious views of what propositional imagining must involve (cf. Everett 2013; cf. also Kung 2016 on the telescopic versus stipulative views of imagining).
