💡 Moving from Level 3 to Level 5 on Duality

🎯 Question Types That Test Duality

Direct theme questions: "How does Stevenson present ideas about duality / identity / human nature?"
Character questions: every Jekyll question is a duality question; every Hyde question is a duality question.
Context questions: Darwin's legacy, Victorian repression, the respectable professional class.
Section B = 30 marks, no SPaG.

📝 Key Command Words

"Commingled": use Stevenson's own word — it names the argument. Good and evil are mixed, not separable.
"Structural argument": the duality is not just a theme but the novella's form — frame narrative, two doors, mystery structure. Name the form.
"Universal, not personal": Jekyll says "man", not "I". Stevenson indicts all Victorian professional men, not one exceptional scientist.

⚠️ Common Mistakes to Avoid

Treating duality as only about good vs evil. Stevenson presents duality as respectable vs repressed — the Victorian professional's private self is not "evil", it is simply human.
Discussing context without connecting it to a specific quote. Darwin, Victorian science, respectability — all must illuminate a textual moment, not float beside it.
Missing the universality. The novella's warning is not about one man's hubris. "All human beings… are commingled" — every reader is implicated.

Mnemonic for the duality theme trajectory?

THESIS → COLLAPSE → VERDICT. Thesis: 'Man is not truly one, but truly two' — confident, universal, Darwinian. Collapse: 'slowly losing hold' — involuntary transformations; the selves merge rather than separate. Verdict: both die; 'doomed to such a dreadful shipwreck' — Stevenson refuses resolution. Remember: the trajectory is Stevenson's argument that duality is universal and separation is impossible — not one man's story, but all men's warning.

Man is not truly one, but truly two.
