I have often thought, if it was not for this tyranny which custom usurps over us, that men of any tolerable good-nature could never be reconciled to the killing of so many animals, for their daily food, as long as the bountiful earth so plentifully provides them with varieties of vegetable dainties. I know that reason excites our compassion but faintly, and therefore I would not wonder how men should so little commiserate such imperfect creatures as crayfish, oysters, cockles, and indeed all fish in general: as they are mute, and their inward formation, as well as outward figure, vastly different from ours, they express themselves unintelligibly to us, and therefore it is not strange that their grief should not affect our understanding which it cannot reach; for nothing stirs us to pity so effectually, as when the symptoms of misery strike immediately upon our senses, and I have seen people moved at the noise a live lobster makes upon the spit, that could have killed half a dozen fowls with pleasure. But in such perfect animals as sheep and oxen, in whom the heart, the brain and nerves differ so little from ours, and in whom the separation of the spirits from the blood, the organs of sense, and consequently feeling itself, are the same as they are in human creatures; I cannot imagine how a man not hardened in blood and massacre, is able to see a violent death, and the pangs of it, without concern. In answer to this, most people will think it sufficient to say, that all things being allowed to be made for the service of man, there can be no cruelty in putting creatures to the use they were designed for; but I have heard men make this reply, while their nature within them has reproached them with the falsehood of the assertion. There is of all the multitude not one man in ten but what will own (if he was not brought up in a slaughter-house), that of all trades he could never have been a butcher; and I question whether ever any body so much as killed a chicken without reluctancy the first time. Some people are not to be persuaded to taste of any creatures they have daily seen and been acquainted with, while they were alive; others extend their scruple no further than to their own poultry, and refuse to eat what they fed and took care of themselves; yet all of them will feed heartily and without remorse on beef, mutton, and fowls, when they are bought in the market. In this behaviour, methinks, there appears something like a consciousness of guilt, it looks as if they endeavoured to save themselves from the imputation of a crime (which they know sticks somewhere) by removing the cause of it as far as they can from themselves; and I can discover in it some strong remains of primitive pity and innocence, which all the arbitrary power of custom, and the violence of luxury, have not yet been able to conquer.
