and the fret People grow old suffer from sickness and experience sorrow Even youth which is often thought of as a happy time does not last forever Keats writes Where youth grows pale and spectre-thin and dies This shows how even the happiest moments of life are fleeting Human beings are aware of their mortality Mortality makes them feel burdened and unhappy For Keats the world of mankind is full of suffering and fleeting which makes him long to escape The Nightingale s Joyful and Eternal World In contrast the nightingale s world is full of joy and freedom The nightingale seems untouched by the sadness and struggles of human life Its beautiful song represents eternal happiness and a connection to nature Keats describes the bird as a Dryad of the trees a Dryad is a tree nymph in Greek mythology This means the nightingale is a magical and timeless beauty of nature The nightingale s song is not just music it feels eternal The nightingale s song has been heard for centuries Keats writes Thou wast not born for death immortal Bird This line shows how the bird s song feels eternal as though it has always existed and will continue forever Unlike humans who must face the reality of death the nightingale seems to live in a world beyond time and mortality Its song is carefree and full of life Thus the nightingale s world is in stark contrast to the sorrows of the human world Keats s Desire for Escape Throughout the poem Keats longs to leave the painful world of mankind and join the nightingale in its eternal joyful world He wishes to escape through wine or poetry He imagines that these would help him fly to the bird s realm He writes Away Away for I will fly to thee But on the viewless wings of Poesy For a brief moment Keats feels as if he has joined the bird and left behind the troubles of human life However this escape does not last The nightingale flies away and leaves Keats behind to face the reality of the human world The poet questions whether his experience was real or just a dream saying Was it a vision or a waking dream This shows that while the nightingale s song offers a glimpse of joy and freedom it cannot fully remove the hardships of human existence To sum up Keats contrasts the world of mankind with that of the nightingale to show the differences between human suffering and the bird s carefree eternal beauty The nightingale s world represents an ideal that Keats longs for but cannot fully reach nbsp
