This is a soliloquy from Hamlet. It can be found in Act 3, Scene 11 of the play, and has become the best-known soliloquy that Shakespeare ever wrote. While there are various other Hamlet soliloquies, this is by far the one most associated with the play and the playwright. It is one of the most famous in the English language, and probably the most oft-repeated quote from the entirety of Shakespeare’s writings.
