I interpret this to mean that you find value in literature, even unscientific as some is, because of the ontology-expanding and vocabulary-expanding potential and for literature's capacity to introduce the reader's mind to new ways of thinking by hinting through ontological structure the author's thought processes...thus hopefully reinforcing or expanding upon the individual reader's humanity by imparting from the sociosphere varied and unique personal human perspectives.
