🔍 Stage 3: THE VERDICT (Chapter 10)

Both Jekyll and Hyde die. This is Stevenson's verdict on the thesis: neither the respectable nor the repressed self can survive without the other. They are not two selves — they are one self, and the attempt to separate them destroys the whole.

Jekyll's full statement is the novella's reckoning. He has been "doomed to such a dreadful shipwreck" — the nautical metaphor of voyage and catastrophe measures the experiment's scope. He set out to master human nature and was mastered by it.

Stevenson's VERDICT is also social: the Victorian gentleman who believed he could maintain perfect separation between his public and private selves discovers that the private self will not be contained forever. Every Jekyll generates a Hyde. Every Hyde is already Jekyll. The duality Stevenson exposes is not pathological — it is normal. That is the horror.

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.
