Note 92 — Chapter VIII

“The remark made by Tiedemann on the imperative intention of tears, is confirmed by similar observations of Charles Darwin’s. At the age of eleven weeks, in the case of one of his children, a little sooner in another, the nature of their crying changed according to whether it was produced by hunger or suffering. And this means of communication appeared to be very early placed at the service of the will. The child seemed to have learnt to cry when he wished, and to contract his features according to the occasion, so as to make known that he wanted something. This development of the will takes place towards the end of the third month.” (Perez, First Three Years of Childhood, English trans., p. 101.)
