Man versus self conflicts in Treasure Island:
One dominant man versus self conflict in Treasure Island concerns Jim's struggle to sort his feelings concerning Long John Silver. He goes from absolutely adoring and practically idolizing the man to discovering that Long John intended to betray him and his friends. Long John's shifting alliances confuse Jim throughout the novel. Once on the island, Jim must reevaluate his opinion of Long John a second time as Long John defends him against his bloodthirsty pirate comrades. Beneath all of his conniving ways, Long John genuinely seems to care for Jim, and Jim knows it; the boy must also sort out his feelings of affection for the pirate versus his sheer dislike of everything that Long John Silver stands for.
