"A nervous excitability, a chronic exaltation of the passion, in which commingle the inferior life of the individual and its exterior manifestations, a state in which sentiment, idea, and will are confounded together, where for the lack of the powerful corrective of logic, the flights of imagination know no bounds, where life and human activity are deprived of a regulator, and move outside of material and concrete factors, by the sole interior force of the soul."
