Mr Birling- “The famous younger generation who know it all. And they can’t even take a joke”
Irony- He derisively labels the younger generation as “know it alls” but ironically he thinks he knows it all - “Titanic”
Priestley deliberately set the play in 1912 to fragmentize (break) the "know it all' ignorance of the older generation.
Speech is cut off: after his callous dismissal of the suicide as a 'joke.
he is abruptly interrupted by the telephone. Through the play form, Priestley can visually depict Mr.
Birling's capitalists beliefs should be physically and symbolically removed from society.
