For me, Moby Dick represents the life itself and captain Ahab, who has lost his leg by the whale, is a man who has been hurt by life and has piled up deep hatred towards it and what it has brought to him. He decides to revenge life, by killing it which is represented by his effort to kill the whale. The book reminds us that one cannot kill life without losing his own life. In fact, life will continue to go on while the man loses his own part of life.This was represented by the big whale coming gloriously out of water while captain Ahab was tied up to its body dead!
