Throughout the morality play, "An inspector calls" Priestley uses Goole as his mouthpiece to show how out of touch of touch the upper class are, from the lives of the proletariat who have struggled throughout 1912 - 1946 through the use of emotive language or declarative statements. This is noticed when all members of the Birling family are responsible for the exploitation & death of Eva smith. Initially, Priestley uses Goole to display him as a Unknown yet dynamic catalyst . This is seen when the inspector arrives the lighting turns from "pink and intimate" to "bright and harder" with the use of the adjective "Bright" to reveal how the inspector is about to shed light on the despicable actions the Birling family had done. Additionally, the use of "Harder" may suggest to the reader, how profound and judgemental the Inspector is likely to be. Moreover, the use of the character name "Goole" suggests a mysterious yet dangerous figure like that of Azrael, the angel of death linking to the 7 deadly sins. Then, when we're introduced to the inspector, Priestley utilizes the inspector as a rational man when he says "Public men Mr Birling, have responsibilities along with privileges" with the Inspector attempting to argue that those with greater authority shouldn't abuse it which was seen in 1912 when the titanic sank as despite women and children being loaded on board most of the working class passengers died compared to that of the upper class. Priestley does this to show the corruption of the upper class. here's 2 paragraphs and the thesis
