Which lines from “The Love Song of J. Alfred Prufrock” best express themes of alienation and isolation? And I have known the arms already, known them all— Arms that are braceleted and white and bare But as if a magic lantern threw the nerves in patterns on a screen:  Would it have been worth while No! I am not Prince Hamlet, nor was meant to be;  Am an attendant lord… I have heard the mermaids singing, each to each. I do not think they will sing to me.
