Priestley uses the Inspector as a vehicle to catalyse change in perception to social responsibility. He encourages the younger generation to break away from the older, more traditional and individualistic generation.
The Inspector's omniscience forces the Birlings & Gerald to recognise the immorality of their actions and change their attitudes towards social responsibility.
[pink and intimate...brighter and harder]
Idiom → 'rose-tinted glasses' - symbolic of the upper class' ignorance to society. The Birling's are lavishing in their lifestyle & privilege, separated from the struggles of the working class. They live in blissful ignorance, blind to societies woes - lacking in social conscience.
Change to an interrogative atmosphere - forceful & impactful.
Light is a symbol of realisation. The Inspector comes and shines a light on each of their indiscretions
[massiveness, solidity and purposefulness]
The Inspector is assertive without being physically or verbally intimidating. His knowledge is what makes him powerful, not his physique.
Mr Birling was the most dominant figure in the house until Inspector Goole arrived and immediately asserted his dominance. Symbolic of Priestley's view that socialism should overpower capitalism (as Mr B is the epitome of capitalism)
The Inspector is Priestley's mouthpiece - deeply set morals that are immovable - contradicts the chaos and fragility of the family.
"We are members of one body"
Allusion to the Book of Genesis - through echoing the words of God, Priestley implies that the Inspector is speaking on God's behalf
"Body" is symbolic of society
Creates a sense that everyone belongs and has an equal place - hinting that society is dysfunctional because of the lack of communication and togetherness
"Better to ask for the Earth than to take it"
Symbolic of how the upper class systematically strips the working class of their rights
