Various motives underlie man's strong impulses to travel. Basic curiosity and exploratory drives occur in man and animal. Glamor and desire for prestige contribute. There may be an unconscious quest for the 'magic helper' described by Fromm. For some there is flight from unsatisfying situations at home, or identification with another country which has been idealized. Travel fosters relaxation of the superego, with free emergence and acting out of id impulses. One's memories of the trip are colored by one's prejudices and needs.
