With reference to these books and the problems of interpretation and meaning that they pose, Bourbon makes a case for the fundamental philosophical character of the study of literature, and for its dependence on theories of meaning disguised as theories of mind. Within this context, he provides original accounts of what sentences, fictions, non-fictions, and poems are; produces a new account of the logical form of fiction and of the limits of interpretation that follow from it; and delineates a new and fruitful domain of inquiry in which literature, philosophy, and science intersect.
