The rights of all creatures are to be respected, but especially of those kinds which man domesticates and subsidizes for his peculiar use. Their nearer contact with the human world creates a claim on our loving-kindness beyond what is due to more foreign and untamed tribes. Respect that claim. "The righteous man," says the proverb, "regardeth the life of his beast." Note that word "righteous." The proverb does not say the merciful man, but the righteous, the just. Not mercy only, but justice, is due to the brute. Your horse, your ox, your kine, your dog, are not mere chattels, but sentient souls. They are not your own so proper as to make your will the true and only measure of their lot. Beware of contravening their nature's law, of taxing unduly their nature's strength. Their powers and gifts are a sacred trust. The gift of the horse is his fleetness, but when that gift is strained to excess and put to wager for exorbitant tasks, murderous injustice is done to the beast. They have their rights, which every right-minded owner will respect. We owe them return for the service they yield, all needful comfort, kind usage, rest in old age, and an easy death.
The day may come when the rest of the animal creation may acquire those rights which never could have been withheld from them but by the hand of tyranny. It may come one day to be recognized that the number of legs, or the villosity of the skin, are reasons insufficient for abandoning a sensitive being to the caprice of a tormentor. What else is it that should trace the insuperable line? Is it the faculty of reason, or perhaps the faculty of discourse? But a full-grown horse or dog is beyond comparison a more rational as well as a more conversable animal than an infant of a day, a week, or even a month old. But suppose the case were otherwise, what could it avail? The question is not "Can they reason?" nor "Can they speak?" but "Can they suffer?"
The disposition to raise the fallen, to befriend the friendless, is now one of the governing powers of the world. Every year its dominion widens, and even now a strong and growing public opinion is enlisted in its support. Many men still spend lives that are merely selfish. But such lives are already regarded with general disapproval. The man on whom public opinion, anticipating the award of the highest tribunal, bestows its approbation, is the man who labors that he may leave other men better and happier than he found them. With the noblest spirits of our race this disposition to be useful grows into a passion. With an increasing number it is becoming at least an agreeable and interesting employment. On the monument to John Howard in St. Paul's, it is said that the man who devotes himself to the good of mankind treads "an open but unfrequented path to immortality." The remark, so true of Howard's time, is happily not true of ours.
