I’m reading Jonathan Rogers’ The World According to Narnia right now, and this section on Eustace Scrubb from The Voyage of the Dawn Treader rang true:
Eustace lacks the one critical skill that makes it possible for a critic to be of some actual use. He lacks the ability to see anybody’s perspective but his own. He stands aside from the goings-on around him, and so he believes he enjoys an objective view of things. In fact, his refusal to engage leaves him with no outside point of reference. It leads to the grossest sort of subjectivity. Because he is seasick, he is convinced that the ship must be sailing through a storm. Nothing can convince him of the truth that the weather is perfect for sailing. Nothing, in fact, can induce him to be interested in the truth, regardless of what he might say about facts and the dangers of wishful thinking. He clings to an almost psychotic version of events that corresponds only to his inner states and has nothing to do with the facts of the outer world.
