“To give them lessons in modesty and good conduct is to teach them that there are things shameful and wicked, and to give them a secret wish to know what these things are. Sooner or later they will find out, and the first spark which touches the imagination will certainly hasten the awakening of the senses. Blushes are the sign of guilt; true innocence is ashamed of nothing.
Children have not the same desires as men; but they are subject like them to the same disagreeable needs which offend the senses, and by this means they may receive the same lessons in propriety. Follow the mind of nature which has located in the same place the organs of secret pleasures and those of disgusting needs; she teaches us the same precautions at different ages, sometimes by means of one idea and sometimes by another; to the man through modesty, to the child through cleanliness.”
