Madame de Stael says that only the people who can play with children are able to educate them. For success in training children, the first condition is to become a child oneself. It means to treat the child as really one’s equal, that is, to show him the same consideration, the same kind of confidence one shows to an adult. It means not to affect the child to be what we ourselves want him to become, but to be affected by the impression of what the child himself is; not to treat the child with cheating, or by force, but with the seriousness and true love suitable to his own character.

Not leaving the child in peace is the greatest problem of present methods of training children. Parents do not see that during the whole life, the need of peace is never greater than in the years of childhood, an inner peace under all outside liveliness.

But what does a child experience? Corrections, orders, interference（干涉）, the whole livelong day. The child is always required to leave something alone, or to do something different, to find something different, or want something different from what he does, or finds, or wants. He is always guided in another direction from the true inner will that is leading him. All of this is caused by our so-called enthusiasm in directing, advising, and helping the child to become the same model produced in one assembly line（流水线）. Understanding, the deepest characteristic of love, is almost always absent.

To bring up a child means carrying one’s soul in one’s hand; it means never placing ourselves in danger of meeting the cold look on the face of the child. It means the truth that the ways of injuring the child are limitless while the ways of being useful to him are few. How seldom does the educator remember that the child, even at four or five years of age, has already had a sharp feeling! The smallest mistrust and unkindness, the least act of injustice, leave wounds that last for life in the heart of the child. While, on the other hand, unexpected friendliness and kindness make quite as deep an impression on those soft senses.
