We have here a case where the love of approbation, strong enough in the
average child to be used in fixing a good habit, does not function. Karl
does not care enough for the approbation of parents, teacher or friends
to make him do a thing not approved by his reason. The incident is
inserted here because it is exceptional and illustrates the occasional
case in which the love of approbation can not be used as an incentive.
As a rule, the love of approval, of being considered “a gentleman” or “a
little lady,” is strong enough to give all the motivation necessary for
teaching good manners.
