Question

what does shakespeare compare to the world and why?

Answer 1

Shakespeare compares the world to a stage in three plays:
In "As You Like It," Jaques, in his set piece on the seven ages of man, begins by declaring "All the world's a stage, and all the men and women in it merely players..."
In "The Merchant of Venice," Antonio (the merchant) says, "I hold the world but as the world a stage, where every man must play a part, and mine a sad one."
"Henry V" opens with the chorus declaiming, "O, for a muse of fire that would ascend the brightest heaven of invention; a kingdom for a stage, princes to act, and monarchs to behold the swelling scene."
Shakespeare was a dramatist, after all, so wouldn't it be natural for him to compare the world to a stage, especially given that we all do, to some degree, "play" our parts, put on a front to disguise our feelings at times?
