Fiction, with its preference for what is small and might elsewhere seem irrelevant; its facility for smuggling us into another skin and allowing us to live a new life there; its painstaking devotion to what without it might go unnoticed and unseen; its respect for contingency, and the unlikely and odd; its willingness to expose itself to moments of low, almost animal being and make them nobly illuminating, can deliver truths we might not otherwise stumble on.
