The story of the word

Jean-Étienne Esquirol proposed monomanie around 1810 for a mind sound on every subject but one, and the courts seized on it at once, since a defendant could now be mad about a single thing and answerable for the rest of his conduct. The diagnosis collapsed within two generations under the weight of its own subdivisions. What survived is the literary sense, fixed for good by Ahab, whose pursuit of the whale Melville calls monomaniac.
