けれども，６ないし７歳で私たちのところ（学校）へやってきた子供たちは，大部分，性器に関連したものは何でも下品なもの（みだらなもの）と見るように，既に教えこまれていた。彼らは，この学校では，そういう事柄が，他の事柄を話す時と同じような声の調子で話されているのを発見してびっくりした。そして，しばらくの間，彼らが下品だと感じている会話をして，一種の解放感を楽しんだ。しかし，大人がそういう会話を一向にやめさせようとしないのがわかって，しだいにその会話に飽きてきて，上品さを教えられなかった子供たちにほとんど同じくらい，さっぱりした気持ちになった。
Most of those, however, who came to us at the age of six or seven had already been taught to regard anything connected with the sexual organs as improper. They were surprised to find that in the school such matters were spoken of in the same tone of voice as was employed about anything else, and for some time they enjoyed a sense of release in conversations which they felt to be indecent ; finding, however, that the grown-ups did nothing to check such conversations, they gradually wearied of them, and became nearly as clean-minded as those who had never been taught decency.
