"A person is not born to be defeated. You can destroy him as much as you can, but you can't beat him. " This is Santiago's life belief and the idea that the author wants to express in The Old Man and the Sea. Through the image of Santiago, the author enthusiastically praised the indestructible spiritual strength of human beings in the face of difficulties and hardships. The child is ready to go out to sea with the old man again. He must learn all the "skills" of the old man, which symbolizes that the "invincible" spirit of mankind will be passed down from generation to generation.
