Priestley primarily uses the characters in the play to present his views, particularly Mr. and Mrs. Birling, to present his ideas about class and society . In the Birling family, Mrs. Birling belongs to the more upper class and always refers to lower-class factory workers, such as Eva Smith, as "girls of that class". She seems to think that working class people aren't human at all. At first, Priestley describes the Birlings' house as "a fairly large suburban house" with "good solid furniture of the period", showing that they are upper middle class and have money. They also have servants like a maid and a cook. Priestley wants to give us an idea that the Birlings are upper class, both in terms of possessions and attitudes. The characters in "An Inspector Calls" are primarily upper-middle class (Mr. and Mrs. Birling, Gerald, Sheila, Eric), but the inspector is middle class and Eva Smith is working class. Most of the characters in "An Inspector Calls" have varying opinions on social classes, but there are mainly two sides. The first main opinion is that the upper middle class is the most important and that the lower working classes are not important and it does not matter what happens to them (this is the opinion of Mr. and Mrs. Birling and Gerald). For example, Sheila and Mrs Birling need to be protected from horrible things such as Eva Smith's death because they are upper middle class, while Eva Smith does not need to be protected from horrible things in life because she is working class. The other opinion is that even if they belong to the working class they should still be treated fairly even if they belong to different classes and Eva Smith's death is very tragic even if she did not belong to the upper class (that of Eric, Sheila and the Inspector). .... middle of paper ...... are lower class or upper class ("[W]e do not live alone. We are members of one body. We are responsible for each other others.") in socialism, he uses the inspector to express his thoughts on this subject. This is the main message he wanted the audience to take away. In “An Inspector Calls,” Priestley presents different ideas about class and society. Its main idea is socialism. He believes that we “don’t live alone.” We are members of one body, we are responsible for each other.” Whether we belong to the upper or lower class, we are responsible for each other and we should not look down on each other. other people or think that they are not humans but creatures simply because they belong to a lower social class than us. Priestley tries to present the idea that society will only work if we work together and are responsible for each other. Otherwise there would be no society.
