Note 373 — Chapter VI
Reading edition
A very common but random opinion traces Rousseau's insanity to certain disagreeable habits avowed in the Confessions. They may have contributed in some small degree to depression of vital energies, though for that matter Rousseau's strength and power of endurance were remarkable to the end. But they certainly did not produce a mental state in the least corresponding to that particular variety of insanity, which possesses definitely marked features.
