Please Help Me Having Critical Analysis Of "The Seven Ages Of Men" By William Shakespeare?

This, one of the most famous metaphors in literature, is Jacque's cynical response to Duke Senior's optimism in the Forest of Arden. The miserabilist "ages" that Jacques goes on to sketch,-all the way from the "Infant,/ Mewling and puking in the nurse's arms", to the "Second childishness and mere oblivion,/ Sans teeth,sans eyes,sans taste,sans everything"  makes rich capital from the human comedy, but, his laughter is hollow. His comedy, furthermore, is rejected by the play. The all inclusive forest delivers the antidote to Jacques maudlin satire, as Rosalind discovers when she finds Orlando's love poems pinned to a tree.  "All the world's a stage, and all the men and women merely players. They have their exits and their entrances/ and one man in his time plays many parts/ his acts being seven ages.   Hope this helps?
