She was arguing in favor of the kinds of insight that can emerge from fiction, with its tension between inner monologue and exterior drama, which can help us understand the complex dynamics of social situations and the hidden frailties or cruelties of other people.
I like this passage because it helps me get an understanding of my book, Under the Harrow. The main character in UTH is woman named, Nora who came to visit her sister Rachel, only to find her murdered in her house> Nora then becomes delusion, sad, angry, all the emotions at once. What Wills is saying in this passage about inner monologue, compliments the book because it helps the reader understand Nora. And she believes this can only be accomplished by a Woman.
