theme of alienation in the old man and the sea

Santiago is a man alienated from society. He is old, arthritic and tired. Not having caught a fish in a long time, the other fishermen laugh at him. The boy Manolin's parents do not want their son fishing with Santiago. The younger fishermen have bigger boats, radios and motors. Santiago has his skiff; it is creaky, old and isolated like Santiago himself.Santiag's world is isolated as well. He lives with thoughts of his grandiose past. His relationship with nature is intense and isolated from others.
