Brief analyze the plot of the old man and the sea

The plot of the novel is very simple, but it contains a deep moral. The novel depicts the protagonist fishing alone in the sea for three days and three nights. In order to highlight the theme that he wants to express, the author throws the hero Santiago into the vast sea, which is almost isolated from the world, and lets him fight with the ocean and sharks alone. In Hemingway's writing, the sea is clearly not only a landscape of nature, but also a symbol of society. Just as Santiago saw fishing not only as a means of making a living, but also as a place for the battle of life. Many times the author uses cold, mysterious words like "black", "dark" and "black" to describe the sea, which is full of marlin and sharks big and small. It was the fury, the savagery, the insidiousness, the unfathomability, the unknowability of the sea when Santiago fought with the sharks that made one shudder. All this made Santiago seem so small and lonely. Thus the image shows that people can not escape the fate of failure in the struggle with the external forces. However, through Santiago's grace in the face of failure, the work emphasizes the theme of being brave in the face of failure.
