Flannery O'connor said this quote
“ The type of mind that can understand good fiction is not necessarily the educated mind, but it is at all times the kind of mind that is willing to have its sense of mystery deepened by contact with reality, and its sense of reality depend by contact with mystery. Fiction should be both canny and uncanny. In a good deal of popular criticism, there is the notion operating that all fiction has to be about the Average Man, and has to depict average ordinary everyday life, that every fiction writer must produce what used to be called a slice of life. But if life, in that sense, satisfied us, there would be no sense in producing literature at all. ”
