Mr Birling is presented as an injudicious character
Mr Birling assumes that he has all the knowledge
Mr Birling: '"I say there isn't a chance of war"'
Mr Birling: '"Unsinkable, absolutely unsinkable"'
Mr Birling is referring to the Titanic and WW1 at Sheila's engagement party
He tends to think positive which shows how his life has been spoiled with money. His optimism and confidence comes from his privileged background
He doesn't struggle in life indicates his lack of understanding of the struggles of others
Repetition of 'unsinkable' shows how he's very certain and confident with his choices
He's very optimistic and he glorifies the future which suggest he's got all the money and power (but he's wrong).His confidence blinds him to the realities of the world
He's very dramatic and over confident. This highlights his arrogance and lack of self-awareness
Believed he is right and everyone else is wrong which demonstrates his inflated sense of self-importance
Use of dramatic irony as audience we know that the WW1 did occur but the character don't know
The titanic sinking foreshadows the birlings sinkingfate after the inspectors arrival
The titanic symbolises the drifting classes during the edwardian era
The Titanic is a metaphor to the different classes of Edwardian society
