A mother of many children may be troubled by her noisy little ones and envy her sterile friend, who in turn may complain of her loneliness; but if they balance what they gain with what they lose, they will find the both sides are equal. The law of balance strictly forbids one's monopoly of happiness. It applies its scorpion whip to anyone who is given to pleasures. Joy in extremity lives next door to exceeding sorrow. "Where there is much light," says Goethe, "shadow is deep." Age, withered and disconsolate, lurks under the skirts of blooming youth. The celebration of birthday is followed by the commemoration of death. Marriage might be supposed to be the luckiest event in one's life, but the widow's tears and the orphan's sufferings also might be its outcome. But for the former the latter can never be. The death of parents is indeed the unluckiest event in the son's life, but it may result in the latter's inheritance of an estate, which is by no means unlucky. The disease of a child may cause its parents grief, but it is a matter of course that it lessens the burden of their livelihood. Life has its pleasures, but also its pains. Death has no pleasure of life, but also none of its pain. So that if we balance their smiles and tears, life and death are equal. It is not wise for us, therefore, to commit suicide while the terms of our life still remain, nor to fear death when there is no way of avoiding it. Again, the law of balance does not allow anyone to take the lion's share of nature's gifts. Beauty in face is accompanied by deformity in character. Intelligence is often uncombined with virtue. "Fair girls are destined to be unfortunate," says a Japanese proverb, "and men of ability to be sickly." "He makes no friend who never makes a foe." "Honesty is next to idiocy." "Men of genius," says Longfellow, "are often dull and inert in society; as the blazing meteor when it descends to earth is only a stone." Honour and shame go hand in hand. Knowledge and virtue live in poverty, while ill health and disease are inmates of luxury. Every misfortune begets some sort of fortune, while every good luck gives birth to some sort of bad luck. Every prosperity never fails to sow seeds of adversity, while every fall never fails to bring about some kind of rise. We must not, then, despair in days of frost and snow, reminding ourselves of sunshine and flowers that follow them; nor must we be thoughtless in days of youth and health, keeping in mind old age and ill health that are in the rear of them. In brief, all, from crowns and coronets down to rags and begging bowls, have their own happiness and share heavenly grace alike. 8. The Application of the Law of Causation to Morals.
