Key Themes & Exam Technique
Theme: Duality of Human Nature
The novella’s central argument is that every person contains both good and evil. Jekyll states: “man is not truly one, but truly two.” He attempts to separate these natures through science, but the experiment proves that they are inseparable. Hyde is not a foreign intruder but the part of Jekyll that society forced him to suppress. The novella argues that repression is more dangerous than acknowledgement: pretending evil does not exist makes it stronger, while recognising it honestly might allow it to be managed.
This theme connects to Victorian rationalism: the idea that civilised behaviour is a permanent achievement rather than a constant effort. Stevenson challenges this: civilisation is a thin veneer, and beneath it lies the same primitive nature that Darwin’s theory revealed. Hyde’s animalistic descriptions (“ape-like fury,” “troglodytic”) remind Victorian readers that evolution did not eliminate the animal — it only covered it with a suit and top hat.
Jekyll believes “man is not truly one, but truly two” and attempts to separate the two. But Stevenson’s novella shows this is impossible: good and evil are inseparable parts of the same person. Hyde cannot be permanently controlled or eliminated because he is Jekyll. The novella argues that managing duality requires honest self-knowledge, not scientific shortcuts.
Theme: Reputation and Secrecy
Every character in the novella guards his reputation obsessively. Jekyll hides Hyde behind a separate identity. Utterson refuses to gossip. Enfield’s rule is “the more it looks like Queer Street, the less I ask.” This culture of secrecy is presented as both symptom and cause of the problem: Victorian gentlemen cannot acknowledge their darker impulses because doing so would destroy their social standing. The result is that secrets fester, hidden selves grow stronger, and the eventual exposure is catastrophic.
Jekyll’s experiment represents science without ethical boundaries. He uses chemistry to achieve what nature forbids: the separation of good and evil. But the experiment is driven by selfish motives (freedom from moral accountability), and its consequences are disastrous. Stevenson was writing during a period of rapid scientific advance, and the novella warns that progress without morality leads to destruction.
Lanyon and Jekyll represent two attitudes to science: Lanyon is cautious and conventional, Jekyll is reckless and innovative. Both are inadequate. Stevenson suggests that science needs both ambition and restraint — a lesson that resonates far beyond the Victorian period.
Most 19th-century prose questions give you a printed extract and ask you to write about the extract and the novella as a whole. The question is worth 40 marks and assesses three objectives: AO1 (a personal response backed by quotations), AO2 (language, form and structure) and AO3 (context). Spelling and grammar carry no marks in this section, so put the time into analysis. Spend a few minutes annotating the extract before writing 4–5 developed paragraphs.
Quotation bank: “Man is not truly one, but truly two” (duality). “The animal within me licking the chops of memory” (temptation). “With ape-like fury” (degeneration). “Deformity without nameable malformation” (indefinable evil). “Both sides were in dead earnest” (genuine duality). “The moment I choose, I can be rid of Mr Hyde” (self-deception). Learn all six and practise linking each to multiple themes.
Connecting Themes
The genius of Jekyll and Hyde is that all themes connect. Duality drives the experiment, which raises questions about science and morality. The experiment must be kept secret because Victorian respectability cannot tolerate the truth about human nature. The secrecy enables Hyde’s crimes, which escalate because evil grows when indulged. The delayed revelation mirrors Victorian society’s refusal to confront what it already knows. In the exam, showing how themes interconnect demonstrates the sophisticated understanding that earns the highest marks.
The four main themes (duality, secrecy/reputation, science/morality, and the nature of evil) are interconnected: duality creates the desire for separation, the experiment requires secrecy, secrecy enables escalation, and escalation proves that evil cannot be controlled. Showing these connections in the exam demonstrates whole-text understanding.
