This pushing of the class boundaries through the use of deceit and exploitation is a motif which is repeated throughout the play. Ibsen uses a range of dramatic techniques in order to challenge audiences. He pushes boundaries, particularly of gender and class in an attempt to depict his view of society. These challenging concepts and ideas, ranging from a mother euthanizing her son to a Pastor donating funds to a brothel succeed in challenging audiences of both 18th century and modern contexts. A truly radical play, Ghosts by Henrik Ibsen depicts a perception of society which is free from typical social conventions.
