Key Themes & Exam Technique
Theme: Duality of Human Nature
The novella’s central theme is that every human being contains both good and evil. Jekyll articulates this directly: “Man is not truly one, but truly two.” His experiment attempts to separate these halves, but fails catastrophically because — as he also admits — “all human beings are commingled out of good and evil.” The two cannot be divided. Attempting to do so does not purify Jekyll; it creates a creature of pure evil (Hyde) while leaving Jekyll weaker and less able to resist.
Stevenson extends duality beyond Jekyll. Utterson has a “dualistic” character: austere yet tolerant. London itself is dual: respectable by day, sinister by night. Even the narrative structure has two faces: the mystery conceals the confession. Duality is not one character’s problem — it is the human condition, and Victorian society’s refusal to acknowledge it is what makes it destructive.
‘Man is not truly one, but truly two’ — but the two halves are ‘commingled’ (inseparable). Jekyll’s experiment fails because separating good from evil is impossible. The potion does not purify; it unleashes. Stevenson argues that acknowledging duality is healthier than repressing it.
Theme: Repression and Its Consequences
Victorian society demanded that professional men suppress all ‘unrespectable’ desires. Jekyll embodies this: “I concealed my pleasures; and when I reached years of reflection… I stood already committed to a profound duplicity of life.” The repression does not eliminate desire — it compresses it. When Hyde finally emerges, he does so with explosive, disproportionate violence. The trampled child, the murdered Carew — these acts are consequences of decades of suppressed impulse.
Stevenson’s message is clear: repression breeds monsters. A society that demands moral perfection will produce spectacular moral failure. The novella is both a psychological study of one man and a social critique of an entire culture.
Jekyll’s experiment raises questions about scientific ethics. He uses chemistry to alter human nature itself — an act of hubris that parallels Frankenstein and anticipates twentieth-century anxieties about genetic engineering. Lanyon, the conventional scientist, dismisses Jekyll’s work as ‘unscientific balderdash’ — but his death after witnessing the transformation suggests that conventional science cannot cope with unconventional truth. Stevenson presents science as both powerful and dangerous: capable of revealing hidden truths but also of unleashing hidden evils.
Theme: Secrecy and Surveillance
The novella is saturated with secrecy. Jekyll hides his dual life. Utterson investigates but respects privacy. Enfield and Utterson agree never to discuss what they’ve seen. Lanyon’s letter is sealed until Jekyll’s death. The narrative is a series of locked doors, sealed documents, and withheld information. Stevenson shows that Victorian respectability was maintained through collective agreement not to look too closely — a conspiracy of silence that enabled both individual and social hypocrisy.
Secrecy pervades every level: Jekyll hides Hyde, Utterson hides his suspicions, Enfield hides what he saw, the narrative hides its truth in sealed documents. Stevenson critiques a culture where respectability depends on collective silence.
Exam Preparation
Your 19th-century novel question offers a choice between an extract-based task and a discursive task. Both assess AO1, AO2, AO3 (context), and AO4 for spelling, punctuation and grammar. Extract-based: Analyse the passage closely (language, imagery, symbolism), then connect to the novella as a whole. Discursive: Build an argument responding to a statement with evidence from across the text. Both require integrated AO1+AO2+AO3 in every paragraph. The question is worth 40 marks and you have about an hour for it. You cannot take the novella into the exam.
Key exam strategies for Jekyll and Hyde: (1) Always treat settings as symbolic — the house, the fog, London’s geography. (2) Analyse Hyde’s physical descriptions as connecting to Darwinian/evolutionary anxiety. (3) Discuss the narrative structure as a method — multiple perspectives, sealed documents, delayed revelation. (4) Embed context: Victorian respectability, post-Darwin science, Gothic tradition.
Point: Stevenson uses Hyde’s physical appearance to embody post-Darwinian anxiety. Evidence: Hyde moves with ‘ape-like fury’ and is described as ‘like a monkey.’ Analysis: The simian imagery connects Hyde to evolutionary regression — the fear that beneath civilised behaviour lies a primitive animal self. The word ‘fury’ suggests this self is not just present but violent, explosive when released. Context: Darwin’s theory that humans evolved from primates terrified Victorians who believed in human exceptionalism. Stevenson weaponises this fear through Hyde’s body.
