Good vs. Evil:
* Good: The novel portrays Jim Hawkins as the main protagonist, a young boy with a strong moral compass. He strives to do what is right and helps his fellow shipmates (most of whom are also good-natured) to survive the dangers of the sea and the machinations of the pirates.
* Evil: The primary antagonists are the pirates led by Long John Silver, driven by greed, violence, and a desire for power. Their pursuit of treasure is ruthless and they resort to treachery and murder to achieve their goals.
The novel explores this conflict throughout the journey, from the initial encounter with the pirates on the island to the final confrontation on the ship and the desperate struggle for survival.
However, the conflict also has other layers:
* Civilization vs. Savagery: The story pits the orderly world of civilization represented by Jim and the ship's captain against the lawless and brutal world of the pirates, where survival of the fittest reigns.
* Youth vs. Experience: Jim's youth and naivete clash with the cunning and experience of the seasoned pirates, highlighting the clash between innocence and corruption.
* Loyalty vs. Betrayal: The story explores the complex web of alliances and betrayals among the crew, raising questions about loyalty and the ethical dilemmas faced when confronted with difficult choices.
Ultimately, the main conflict in Treasure Island is a complex one that revolves around the struggle between good and evil, but it also examines themes of civilization vs. savagery, youth vs. experience, and loyalty vs. betrayal, making it a compelling and timeless story.
