Love: A temporary insanity curable by marriage

Love: A temporary insanity curable by marriage or by the removal of the patient from the influences under which he incurred the disorder. This disease, like caries and many other ailments, 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.
Ambrose Bierce, The Devil's Dictionary
