"is always very unwilling to tell his real name, and there is no doubt that this reluctance is due to the fear that through his name he may be injured by sorcerers." Amongst the tribes of Central Australia every man, woman, and child has, besides a personal name which is in common use, a secret or sacred name which is bestowed by the older men upon him or her soon after birth, and which is known to none but the fully initiated members of the group. This secret name is never mentioned except upon the most solemn occasions; to utter it in the hearing of women or of men of another group would be a most serious breach of tribal custom, as serious as the most flagrant case of sacrilege among ourselves. When mentioned at all, the name is spoken only in a whisper, and not until the most elaborate precautions have been taken that it shall be heard by no one but members of the group. "The native thinks that a stranger knowing his secret name would have special power to work him ill by means of magic."
The same fear seems to have led to a custom of the same sort amongst the ancient Egyptians, whose comparatively high civilisation was strangely dashed and chequered with relics of the lowest savagery. Every Egyptian received two names, which were known respectively as the true name and the good name, or the great name and the little name; and while the good or little name was made public, the true or great name appears to have been carefully concealed. A Brahman child receives two names, one for common use, the other a secret name which none but his father and mother should know. The latter is only used at ceremonies such as marriage. The custom is intended to protect the person against magic, since a charm only becomes effectual in combination with the real name. Similarly, the natives of Nias believe that harm may be done to a person by the demons who hear his name pronounced. Hence the names of infants, who are especially exposed to the assaults of evil sprits, are never spoken; and often in haunted spots, such as the gloomy depths of the forest, the banks of a river, or beside a bubbling spring, men will abstain from calling each other by their names for a like reason.
The Indians of Chiloe keep their names secret and do not like to have them uttered aloud; for they say that there are fairies or imps on the mainland or neighbouring islands who, if they knew folk's names, would do them an injury; but so long as they do not know the names, these mischievous sprites are powerless. The Araucanians will hardly ever tell a stranger their names because they fear that he would thereby acquire some supernatural power over themselves. Asked his name by a stranger, who is ignorant of their superstitions, an Araucanian will answer, "I have none." When an Ojebway is asked his name, he will look at some bystander and ask him to answer. "This reluctance arises from an impression they receive when young, that if they repeat their own names it will prevent their growth, and they will be small in stature. On account of this unwillingness to tell their names, many strangers have fancied that they either have no names or have forgotten them."
