Why the old man didn't successed in the end?

Why didn't Hemingway let the old man win in the end? Isn't this a better way to reflect the greatness and vitality of heroes? The story of the old man not only symbolizes the relationship between man and nature, but also symbolizes the indestructible spirit of the whole mankind. In reality, although he failed, but in spirit, he is the winner. His tenacious fighting spirit shows the dignity and dignity of human beings. Looking at all life, who hasn't experienced failure? No matter how successful they are. The reasons for failure can be different, but in any case, failure is always an unbearable blow. If you go to sea again, you will have a chance to win. I think this dangerous life environment and this tough attitude towards life are the reasons why this work is more and more attractive. Life is an endless pursuit. In the story, the old man once said, "no one is born for failure. A person can be destroyed, but not defeated." This sentence reminds me of Beethoven's "Symphony of fate", Beethoven once said: "I can be destroyed, but I can't conquer." They explain the meaning of heroes, the meaning of life. And this sentence also points out the idea of the article: people should face failure bravely. From this point of view, this book is not a fable or a fairy tale, but a realistic work. Victory is no longer important in this novel. What matters is the value of one's life. The old man dares to challenge the limit and surpass it again and again. We have to admire him. What he brings to mankind is a kind of self-confidence and a kind of powerful spiritual strength.
