74 “Granted that any practice causes more pain to animals than it gives pleasure to man; is that practice moral or immoral? And if exactly in proportion as human beings raise their heads out of the slough of selfishness they do not with one voice answer ‘immoral,’ let the morality of the principle of utility be for ever condemned.”—Mill’s _Dissert_. vol. ii. p. 485. “We deprive them [animals] of life, and this is justifiable—their pains do not equal our enjoyments. There is a balance of good.”—Bentham’s _Deontology_, vol. i. p. 14. Mr. Mill accordingly defines the principle of utility, without any special reference to man. “The creed which accepts as the foundation of morals, utility or the great happiness principle, holds that actions are right in proportion as they tend to promote happiness, wrong as they tend to produce the reverse of happiness.”—_Utilitarianism_, pp. 9-10. 75 The exception of course being domestic animals, which may be injured by ill treatment, but even this exception is a very partial one. No selfish reason could prevent any amount of cruelty to animals that were about to be killed, and even in the case of previous ill-usage the calculations of selfishness will depend greatly upon the price of the animal. I have been told that on some parts of the continent diligence horses are systematically under-fed, and worked to a speedy death, their cheapness rendering such a course the most economical. 76 Bentham, as we have seen, is of opinion that the gastronomic pleasure would produce the requisite excess of enjoyment. Hartley, who has some amiable and beautiful remarks on the duty of kindness to animals, without absolutely condemning, speaks with much aversion of the custom of eating “our brothers and sisters,” the animals. (_On Man_, vol. ii. pp. 222-223.) Paley, observing that it is quite possible for men to live without flesh-diet, concludes that the only sufficient justification for eating meat is an express divine revelation in the Book of Genesis. (_Moral Philos._ book ii. ch. 11.) Some reasoners evade the main issue by contending that they kill animals because they would otherwise overrun the earth; but this, as Windham said, “is an indifferent reason for killing fish.”
