Seven Ages of Man

"All the world's a stage" is the phrase that begins a monologue from William Shakespeare's As You Like It, spoken by the melancholy Jaques in Act II Scene VII. The speech compares the world to a stage and life to a play, and catalogues the seven stages of a man's life, sometimes referred to as the seven ages of man:infant, schoolboy, lover, soldier, justice, Pantalone and old age, facing imminent death. It is one of Shakespeare's most frequently quoted passages.

    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 schoolboy, 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 honor, 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 lined,
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 slippered pantaloon,
With spectacles on nose and pouch on side;
His youthful hose, well saved, 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.

The comparison of the world to a stage and people long predated Shakespeare. Richard Edwardes's play Damon and Pythias, written in the year Shakespeare was born, contains the lines, "Pythagoras said that this world was like a stage / Whereon many play their parts; the lookers-on, the sage". When it was founded in 1599 Shakespeare's own theatre, The Globe, may have used the motto Totus mundus agit histrionem (All the world plays the actor), the Latin text of which is derived from a 12th-century treatise. Ultimately the words derive from quod fere totus mundus exercet histrionem (because almost the whole world are actors) attributed to Petronius, a phrase which had wide circulation in England at the time.
