By connecting coarse words with the unpleasant ideas which belong to them, you quench the first spark of imagination. You do not forbid the child to say these words or to form these ideas; but without him thinking about it you make recalling them repugnant to him.
En joignant aux mots grossiers les idées déplaisantes qui leur conviennent, on étouffe le premier feu de l’imagination: on ne lui défend pas de prononcer ces mots et d’avoir ces idées; mais on lui donne, sans qu’il y songe, de la répugnance à les rappeler.
