Heredity, which means qualities derived from parentage, is a prophecy of life. Therefore let parents render themselves as perfect in health, as wise in mind, and as self-respecting in manners as they can; for their qualities in some degree will appear in their offspring. One advantage of children is that they contribute unconsciously to the education of parents. No parents of sense can fail to see that children are as imitative as monkeys, and have better memories. Not only do they imitate actions, but repeat forms of expression, and will remember them ever after. The manners of parents become more or less part of the manners and mind of the child. Sensible parents, seeing this, will put a guard upon their conduct and speech, so that their example in act and word may be a store-house of manners and taste from which their children may draw wisdom in conduct and speech. The minds of children are as photographic plates on which parents are always printing something which will be indelibly visible in future days. Therefore the society, the surroundings, the teachers of the child, so far as the parents can control them, should be well chosen, in order that the name borne by the young shall command respect when their time comes to play a part in the drama of life. To this end a child should be taught to take care what he promises, and that when he has given his promise he has to keep it, for he whose word is not to be trusted is always suspected, and his opinion is not sought by others, or is disregarded when uttered. A child should early learn that debt is dependence, and the habit of it is the meanness of living upon loans. There can be no independence, no reliance upon the character of any one, who will buy without the means of payment, or who lives beyond his income. Such persons intend to live on the income of some one else, and do it whether they intend it or not. He alone can be independent who trusts to himself for advancement. No one ought to be helped forward who does not possess this quality, or will not put his hand to any honest work open to him. Beware of the child who has too much pride to do what he can for his own support, but has not too much pride to live upon his parents, or upon friends. Such pride is idleness, or thoughtlessness, or both, unless illness causes the inability. Since offspring have to be trained in health and educated in the understanding, there must not be many in the family unless the parents have property. The poor cannot afford to have many children if they intend to do their duty by them. It is immoral in the rich to have many because the example is bad, and because they are sooner or later quartered upon the people to keep them; or, if they are provided for by their parents, they are under no obligation to do anything for themselves, which is neither good for them nor good for the community, to which they contribute nothing.
