Priestley's use of contrasting adjectives creates a sense of confusion, implying perhaps that Eric is a secretive person
Priestley wants the audience to view Eric negatively
To show that the capitalist patriarchal society is not trustworthy
Priestley repeats the word 'half' to emphasise that Eric's character is not yet fully formed, which indicates that he might change
Priestley associates Eric with alcohol
When his sister, Sheila, accuses him of being 'squiffy'
'Squiffy'
Slightly drunk
Sheila's use of informal language positions the Birling siblings as fashionable members of the younger generation who adapt their language to the times
Priestley aligns Eric with alcohol
To foreshadow the later revelations about his drunken behaviour on the night that he met Eva Smith
Eric's free and easy use of alcohol is used to signify the double standard in society for men and women
Eric: 'Because of alcohol, he was 'in that state when a chap easily turns nasty''
'That state'
Eric appears to be appealing to a commonly shared belief that his listeners have been drunk and understand exactly what 'that state' is
Eric's use of the third person with the phrase 'a chap' distances him from the implied rape
Priestley presents us with Eric's perspective about Eva, so we do not know the exact details of whether she was a prostitute
If Eva was not working as a prostitute, she seemed to be living a life on the brink of prostitution
Prostitution, and the word prostitute would not be used in the play—at that time, other plays had been censored for making references to prostitutes
Eric: 'And that's when it happened. And I don't even remember—that's the hellish thing'
Eric's lack of detail about what happened suggests that he can barely bring himself to admit what he has done
Eric: 'you're not the kind of father a chap could go to when he's in trouble'
Eric is providing short-term solutions (by asking Eva to marry him and supporting her with stolen money), but he does not see the long-term consequences of his criminal behaviour
By the end of the play, Eric, like Sheila, has learned the lesson of collective social responsibility
Eric: 'We did her in all right'
Eric deliberately uses the plural personal pronoun 'we' to emphasise that it is not just his mother who is responsible for Eva's death, but all of them
Eric's language echoes that of the inspector, the mouthpiece of Priestley
Priestley has presented Eric as an immature young man with a drinking problem, an exploiter of Eva, and a thief
As Eric matures and accepts responsibility for his actions, he becomes receptive to the inspector's message that 'We are members of one body. We are responsible for each other'
