Who said All the world's a stage?

Answer 1

This line is said by the character Jaques in Shakespeare's play As You Like It. The particular speech from which it comes is very famous, and has often been incorrectly anthologized as a poem called "The Seven Ages of Man". But it's not a poem, it's a speech from a play.

Answer 2

This is Jacques monologue from the Shakespearean play, As You Like It, Act 2, scene 7, 139-143:

[in toto]

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. At first the infant,

Mewling and puking in the nurse's arms;

Then the whining school-boy, with his satchel

And shining morning face, creeping like snail

Unwillingly to school. And then the lover,

Sighing like furnace, with a woeful Ballad

Made to his mistress' eyebrow. Then a soldier,

Full of strange oaths, and bearded like the pard,

Jealous in honour, sudden and quick in quarrel,

Seeking the bubble reputation

Even in the cannon's mouth. And then the justice,

In fair round belly with good capon lin'd,

With eyes severe and beard of formal cut,

Full of wise saws and modern instances;

And so he plays his part. The sixth age shifts

Into the lean and slipper'd pantaloon,

With spectacles on nose and pouch on side;

His youthful hose, well sav'd, a world too wide

For his shrunk shank; and his big manly voice,

Turning again toward childish treble, pipes

And whistles in his sound. Last scene of all,

That ends this strange eventful history,

Is second childishness and mere oblivion;

Sans teeth, sans eyes, sans taste, sans everything.
