Focusing on the overarching theme of religious satire in Adventures of Huckleberry Finn, this study reveals the novel's hidden motive, moral and plot. The author considers generations of criticism spanning the 19th, 20th and 21st centuries, along with new textual evidence showing how Twain's richly evocative style dissects Huck's conscience to propose humane amorality as a corrective to moral absolutes. Jim and Huck emerge as archetypal twins—biracial brothers who prefigure America's color-blind ideals.
