Whatever the prevailing morality of a community may demand, the fact remains that practically all children up to a certain age consider it perfectly legitimate to lie to their enemies if they but tell the truth to their friends. Children may lie to the policeman, or to the teacher, or to anyone with whom they are for the moment in conflict. This is a relic of the time when our savage ancestors found it necessary to practice deceit in order to save themselves from their enemies. So ingrained is this instinct that many a child will stick to a falsehood before the teacher or other inquisitors, only to retract and "go to pieces" when obliged to answer his mother. It has been shown over and over again that children even well along in the teens consider it quite right to tell one story to a teacher or to another child who is disliked, and a different story to one that is liked. This attitude probably arises not so much from a desire to deceive as an outcome of natural cunning and adaptability. This is illustrated by the little girl who used to throw the crust of her bread under the table, to get more soft bread. The child was too young to deceive anyone; she could not possibly have the idea of deceit or of lying. She had simply come to dispose of the crust in this way because she had associated the arrival of more bread with her empty-handedness; to throw the bread under the table was a direct way to the getting of what she wanted. The question of truth or untruth never entered the little mind. To treat this child as a liar would not only be unjust, but would be apt to make the child conscious of the idea of deceit. Later in his development the child may still use the same kind of cunning in getting what he wants or in escaping what he does not like, without the intention to deceive. And a lie, to be a lie, must include that intention.
