Symbolism in Dr Jekyll and Mr Hyde

The duality of Dr Jekyll and Mr Hyde themselves is the most prominent symbol in the novel, representing the inherent dual nature of humanity, with its potential for both good and evil. Dual nature is a key idea that comes up repeatedly in various forms throughout the book.
The door that leads to Mr Hyde’s residence is an important symbol of separation between the two characters and the two sides of human nature. It is described as being “blistered and disdained”, reflecting the neglect and degradation of Hyde’s evil half.
The physical transformation of Dr Jekyll into Mr Hyde is not just literal, but also symbolic. Human transformation stands for the ability of humans to shift between moral and immoral states.
London’s foggy streets are used as a symbol for mystery and anonymity, reflecting the murky secrets and hidden identities that form the core of the narrative.
The canes used by both Dr Jekyll and Mr Hyde are an embodiment of their double identity, being both a gentleman’s walking stick and a weapon for violence.
Utterson’s dreams serve as symbolic warnings or premonitions of the dark truth lying beneath Jekyll’s respectable exterior. They play a key role in foreshadowing later events in the plot.
Lastly, look out for the symbolism in the descriptions of physical settings. For example, Jekyll’s house and laboratory reflect his split personality. The front of the house is well-kept and respectable, symbolizing Jekyll, while the run-down laboratory at the back of the house, accessible through a grimy back door, symbolizes Hyde.
