Although Nabokov presents a fascinating theory about how to be a good reader, I believe his theory is too arbitrary. I believe his theory forgets the fact that people read for many different purposes.
Nabokov claims that in order to truly appreciate the characters in a story, a reader should not relate to them. I, however, believe that motive for reading a story may be to find comfort in relating to a character. From the authors perspective, Nabokov fails to recognize that their purpose in writing may be to connect with a specific audience.
Furthermore, while re-reading is important to fully understanding a book, one may re-read simply to enjoy themselves. To enjoy the world of the book another time, not to probe at the authors meaning.
Whether people want to read to understand the authors full purpose, relate and empathize to characters, or to be taken back into a comforting world, they should still be considered good readers.
