Temporal lobe epilepsy often causes changes in behavior and thinking even when the patient is not having seizures. These changes include hypergraphia (voluminous writing), an intensification but also a narrowing of emotional response, and an obsessive interest in religion and philosophy.
Dostoevsky often wrote of the rapture he felt during a seizure when he was in the frightful presence of the universal harmony.
