Suggestion is the awakening of like mental attitude by means of inner imitation. Thus in every suggestion we find two agents involved—the transferer and the imitator; therefore an active and passive side appear in the occurrence. The activity in making a suggestion is called ‘‘suggestivity’’, the passive reception “suggestibility”. For instance, the mother’s attitude is strongly suggestive and the child’s attitude to her one of suggestibility. These few words in explanation of the main ideas.
