Mr Birling

• "A man has to mind his own business and look after himself and his own"

  Shows Capitalism and the Ignorant Mindset of the Upper class.
• "Unskinkable, absolutely unsinkable" "Silly War Cares" "And I say there isn't a chance of war"

  Priestley Uses dramatic Irony, As war DOES happen and the titanic DOES sink. He is made to look stupid and is untrusted.
