 Another explanation of imaginative resistance that locates the source of resistance reactions somewhere other than the imagination puts emotions center stage. Ronald de Sousa (2010) claims that what is going on in resistance cases is not that we are unable to make sense of the content of the imagined situation but that we fail to experience certain emotional responses or fail to respond altogether to certain imagined prospects. For instance, Giselda engenders moral repulsion on the side of the imaginer while prescribing that they feel moral allegiance or approval. The knock-knock joke, on the other hand, fails to engender amusement while the author insists that we find it hilarious.
