🏛️ Darwin, Freud, and the Victorian Self

Stevenson writes Jekyll and Hyde in 1886 — twenty-seven years after Darwin's On the Origin of Species (1859) had shattered the idea that humans were divinely ordered, morally elevated above the animal world. Darwin's work made the "beast within" scientifically plausible: humans had evolved from primitive ancestors, and those primitive impulses might not have vanished.

Victorian respectability was partly a response to this anxiety. The professional classes built elaborate codes of conduct, dress, speech, and social interaction precisely to distance themselves from the animal. Jekyll is the perfect Victorian professional: the respectability is not incidental — it is armour against the Darwinian self.

How this connects to the text: When Stevenson writes that Hyde has "borne the imprint of deformity without any nameable malformation" and is described by multiple witnesses as ape-like, he is deploying the Darwinian vocabulary his readers already feared. Jekyll's experiment does not create Hyde; it removes the armour that prevents Jekyll from seeing that Hyde was always there. "All human beings, as we meet them, are commingled out of good and evil" — Stevenson's thesis is Darwinian, not Gothic: the duality is biological, not supernatural.

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.
