The book is finished by the reader. A good novel should invite the reader in and let the reader participate in the creative experience and bring their own life experiences to it, interpret with their own individual life experiences. Every reader gets something different from a book and every reader, in a sense, completes it in a different way.

If you can get so that you can give that to people, then you are a writer.
The book, the college, the school of art, the institution of any kind, stop with some past utterance of genius. . . . They look backward and not forward. But genius looks forward: the eyes of man are set in his forehead, not in his hindhead: man hopes: genius creates. Whatever talents may be, if the man create not, the pure efflux of the Deity is not his; - cinders and smoke there may be, but not yet flame.
