Ambrose Bierce on Insanity

“Mad, adj. Affected with a high degree of intellectual independence; not conforming to standards of thought, speech, and action derived by the conformants from study of themselves; at odds with the majority; in short, unusual. It is noteworthy that persons are pronounced mad by officials destitute of evidence that they themselves are sane.”

“Love: A temporary insanity curable by marriage or by removal of the patient from the influences under which he incurred the disorder. This disease is prevalent only among civilized races living under artificial conditions; barbarous nations breathing pure air and eating simple food enjoy immunity from its ravages. It is sometimes fatal, but more frequently to the physician than to the patient.”
