Theory #1: Your favorite Austen novel has a heroine whose personality is akin to yours. It has long been my theory that which Austen novel one prefers could be used as a personality category. Perhaps not as useful as Myers-Briggs, but useful all the same. In truth, I have not collected enough data to support or disprove, and since I formulated this theory in my teens, I am willing to confess I may have been more motivated by a desire to compare myself to Elizabeth Bennet than by the demands of purest science.
Theory #2: You can determine your favorite Austen novel by rereading any of the others. This is especially important if #1 is to be believed: we need a way of experimentally determining someone’s favorite, rather than trusting them when they say “Oh, not Emma,” thinking I don’t want Felicity to say I’m an Emma! This I only recently realized. Every time I reread another Austen novel, I find myself longing to reread Pride and Prejudice as soon as I finish. Therefore, whether or not #1 allows me to flatter myself, Pride and Prejudice must be my real favorite.
Of course, since I just came up with #2, I’ve no idea whether this longing occurs to anyone else. Well? Gentle reader, my eagerness to hear your views can well be imagined.
