All the world's a stage
"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, pantaloon, and second childhood, sans. It is one of Shakespeare's most frequently-quoted passages, and is mistakenly believed by some to be Shakespeare's last speech.
The ages 
The man in the poem goes through these stages:
- Infancy: In this stage he is a helpless baby and knows little.
- Childhood: It is that stage of life that he begins to go to school. He is unwilling to leave the protected environment of his home as he is still not confident enough to exercise his own discretion.
- The lover: In this stage he is always remorseful due to some reason or other, especially the loss of love. He tries to express feelings through song or some other cultural activity.
- The soldier: It is in this age that he thinks less of himself and begins to think more of others. He is very easily aroused and is hot headed. He is always working towards making a reputation for himself and gaining recognition, however short-lived it may be, even at the cost of his own life.
- The justice: In this stage he has acquired wisdom through the many experiences he has had in life. He has reached a stage where he has gained prosperity and social status. He becomes very attentive of his looks and begins to enjoy the finer things of life.
- Old Age: He begins to lose his charm — both physical and mental. He begins to become the butt of others' jokes. He loses his firmness and assertiveness, and shrinks in stature and personality.
- Extreme old age: He loses his status and he becomes a non-entity. He becomes dependent on others.
The comparison of the world to a stage and people to actors long predated Shakespeare. 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 exerceat histrionem (because almost the whole world are actors) attributed to Petronius, a phrase which had wide circulation in England at the time.
In his own earlier work, The Merchant of Venice, Shakespeare also had one of his main characters, Antonio, comparing the world to a stage:
- "I hold the world but as the world, Gratiano;
- A stage where every man must play a part,
- And mine a sad one."
- (The Merchant of Venice, Act I, Scene I)
In his work The Praise of Folly, first printed in 1511, Renaissance humanist Erasmus asks, "For what else is the life of man but a kind of play in which men in various costumes perform until the director motions them offstage?"
Likewise the division of human life into a series of ages was a commonplace of art and literature, which Shakespeare would have expected his audiences to recognize. The number of ages varied: three and four being the most common among ancient writers such as Aristotle. The concept of seven ages derives from medieval philosophy, which constructed groups of seven, as in the seven deadly sins, for theological reasons. The seven ages model dates from the 12th century. King Henry V had a tapestry illustrating the seven ages of man.
According to T. W. Baldwin, Shakespeare's version of the concept that the world is a stage is based primarily upon Palingenius' book Zodiacus Vitae, a school text he would have studied at the Stratford Grammar School, which also enumerates stages of human life. He also takes elements from Ovid and other sources known to him. 
All the World's a Stage monologue 
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.
And 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 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 slipper'd 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.
Shakespeare compares the world with a stage in a theatre and men and women with the players on that stage. Like the stage in the theatre, life too has its entrances and exits. A man plays his role through the seven ages of life. The first role/age is that of an infant. He cries and whines and vomits in the hands of his nurse. In the second stage of life, man plays the role of a little child. He carries a small schoolbag with him and has a shiny face, walking as slowly as possible because of his dislike of school. In the third stage of life, man plays the role of a lover. He falls in love passionately and sings a sad ballad about love, praising the beauty of his lover’s eyebrows. In the fourth stage of life, man plays the role of a soldier. He is full of strange oaths, bearded, and strives for honour, recognition and reputation, even faced with a cannon. In the fifth stage of life, man plays the role of a justice. He is well fed and has a fat belly. He is full of wise sayings. He uses his experience, wisdom and knowledge in the dispensation of justice. In the sixth stage of life, man becomes weak and fragile. He wears baggy clothes and his deep manly voice becomes high-pitched and whistly. Man’s last stage is that of extreme old age. This stage is compared to second childhood. He loses control over his senses and becomes dependent on others just like a child. He becomes a victim of forgetfulness and loses his teeth, eyesight, hearing, etc. and then, he passes away.
