Though responsibility itself is a central theme of the play, the last act of the play provides a fascinating portrait of the way that people can let themselves off the hook. If one message of the play is that we must all care more thoroughly about the general welfare, it is clear that the message is not shared by all. By contrasting the older Birlings and Gerald with Sheila and Eric, Priestley explicitly draws out the difference between those who have accepted their responsibility and those who have not.
An inspector calls is a murder mystery with a strong moral message set at the peak Edwardian era of hypocrisy, great wealth, misery, luxury and social debates. It was written in 1945, just after the end of the Second World War but set in 1912, the Edwardian period. This era was described as the Golden age. It was an extremely wealthy society, full of opulence with British power and wealth at its zenith. It was full of proud men and women, honoured to belong to what they thought of as `the best nation in the world' and with four million people, was the world's biggest city. Proms, concerts, musicals and plays hosted the work of upcoming talent. The upper class lived a life of pure extravagant luxury.
J.B. Priestley uses a range of effective devices in ´An Inspector Calls’ to promote his views on social responsibility including character and action, dramatic devices, language as well as historical and social setting. Written in 1945 and first produced in 1945, the play was set in 1912 just before World War One where in Britain 5% of the population owned 87% of the wealth. Therefore, the majority of people were very poor and only a few individuals were affluent. Despite the play being set in 1912, it was produced in 1945 because Priestley wrote it to encourage people to make a fresh start and to enable life never to be the same for the people of post-war Britain.
One way of promoting his views is through characters. Mr. Birling represents
