Inspector Goole is the character in "Inspector Calls" play written by J.B Priestley in 1945 that I will be analysing. He is a strange character, that as specific role in the play, and it is said he is Priestley "mouthpiece", this means that the inspector is the voice of Priestley during the play. The Inspector creates an impression of massiveness and purposefulness, and is role is to undermine the Birlings complacency, to teach them a moral lesson, which he just, managed to do to some characters, and he was also a "catalyst" which made the Birling confess their "crimes" quicker.
He arrives at the Birlings house in the middle of Act 1 and starts his job right away by interrogating Mr Birling and giving moralistic answers, which Mr Birling always replies defensively. "If you don't come down sharply on some of these people they'd soon be asking for the earth" and the Inspector reply was "It's better to ask for The Earth than to take it".
This shows that Mr Birling has a complete different way of thinking compared to the Inspector, because Birling is a capitalist and the Inspector is a socialist, so that is why the Inspector dislikes Mr Birling from the beginning to the end, and treats him worst than the others, and so his moralistic quotes have no affect on Mr. Birling.
Gerald is also involved in the conversation and backs up Birling, and defends him, when Inspector Goole starts talking a bit too agressive to Birling, but the Inspector doesn't get unsettled, and he replies moralistically once more. "We are all respectable citizens as I'm concerned not criminals" and the Inspector answer is "There isn't much difference as you think". This shows that Gerald is on Birling side, and that he shows respect...
