Huck's moral instincts are better than he himself can understand. (Notice, incidentally, how Huck's lack of education is communicated by word choice and syntax and how sparse the misspellings are.) So author and reader are in intellectual opposition to Huck the narrator, but morally identify with him. Similarly reliable "unreliable" narrators, whose distorted views reveal a strangely accurate portrait of the social institutions that confine them, include Chief Bromden, the narrator of Ken Kesey's One Flew Over the Cuckoo's Nest, and the "hysterical" wife and patient, forbidden to write, who relates Charlotte Perkins Gilman's 1892 story "The Yellow Wallpaper."
