“But if man's affection be one of passion, then it is moved also in regard to other animals: for since the passion of pity is caused by the afflictions of others; and since it happens that even irrational animals are sensible to pain, it is possible for the affection of pity to arise in a man with regard to the sufferings of animals. Now it is evident that if a man practice a pitiful affection for animals, he is all the more disposed to take pity on his fellow-men: wherefore it is written (Prov. 12:10): "The just regardeth the lives of his beasts: but the bowels of the wicked are cruel." Consequently the Lord, in order to inculcate pity to the Jewish people, who were prone to cruelty, wished them to practice pity even with regard to dumb animals, and forbade them to do certain things savoring of cruelty to animals. Hence He prohibited them to "boil a kid in the milk of its dam"; and to "muzzle the ox that treadeth out the corn"; and to slay "the dam with her young."”

“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 connected, and neither can be fully realized alone.”

“It is an act of cruelty, of barbarism, to kill, to strike unconscious, and to cut the throat of animals, who do no harm to anyone, the way we do; because they are sensitive to injury and pain just as we are, regardless of what is said vainly, falsely, and ridiculously by our new Cartesians, who regard them as purely machines without soul and without feelings … This is a ridiculous opinion, a pernicious principle, and a detestable doctrine, because it clearly tends to stifle in the hearts of men all feelings of kindness, of gentleness, and of humanity that they might have toward these poor animals. … Blessed are the nations that treat them kindly and favorably, who are compassionate toward their miseries and their pains; but cursed are the nations that treat them cruelly, who tyrannize over them, who enjoy shedding their blood, and who are avid to eat their flesh.”
