The affection of parents makes infants feel safe in this dangerous world, and gives them boldness in experimentation and in exploration of their environments.

Mothers are fonder than fathers of their children because they are more certain they are their own.

If children learn of sex as a relation between their parents to which they owe their own existence, they learn of it in its best form and in connection with its biological purpose.

All men are children, and of one family. The same tale sends them all to bed, and wakes them in the morning.

A child develops best when, like a young plant, he is left undisturbed in the same soil. Too much travel, too much variety of impressions, are not good for the young, and cause them as they grow up to become incapable of enduring fruitful monotony.

A baby is God's opinion that the world should go on.
