The emancipation of men from cruelty and injustice will bring with it in due course the emancipation of animals also. The two reforms are inseparably… - Henry Stephens Salt

Has the artist ever considered the history of the "chop" which is brought so elegantly to his studio? … He has first employed a slaughterman … to convert a beautiful living creature into a hideous carcase, to be displayed with other carcases in that ugliest product of civilisation, a butcher's shop, and then he has employed a cook to conceal, as far as may be, the work of the slaughterman. This is what the Spectator calls being "humanised" by schools of cookery; I should call it being de-humanised.

It is often said, as an excuse for the slaughter of animals, that it is better for them to live and to be butchered than not to live at all. … In fact, if we once admit that it is an advantage to an animal to be brought into the world, there is hardly any treatment that cannot be justified by the supposed terms of such a contract. Also, the argument must apply to mankind. It has, in fact, been the plea of the slave-breeder; and it is logically just as good an excuse for slave-holding as for flesh-eating. It would justify parents in almost any treatment of their children, who owe them, for the great boon of life, a debt of gratitude which no subsequent services can repay. We could hardly deny the same merit to cannibals, if they were to breed their human victims for the table, as the early Peruvians are said to have done.

In the writings of such "pagan" philosophers as Plutarch and Porphyry we find a humanitarian ethic of the most exalted kind, which, after undergoing a long repression during medieval churchdom, reappeared, albeit but weakly and fitfully at first, in the literature of the Renaissance, to be traced more definitely in the eighteenth century school of "sensibility." But it was not until after the age of Rousseau, from which must be dated the great humanitarian movement of the past century, that Vegetarianism began to assert itself as a system, a reasoned plea for the disuse of flesh-food.
