“Single-mindedness is all very well in cows or baboons; in an animal claiming to belong to the same species as Shakespeare it is simply disgraceful.”

“Love in animals, has not for its only object animals of the same species, but extends itself farther, and comprehends almost every sensible and thinking being. A dog naturally loves a man above his own species, and very commonly meets with a return of affection.”

“The person who is certain, and who claims divine warrant for his certainty, belongs now to the infancy of our species.”

“A cow is a very good animal in the field; but we turn her out of a garden.”

“Female animals defending their young are notoriously ferocious and lack the playful delight in combat which characterizes the mock combats of males of the same species. There seems very little ground for claiming that the mother of young children is more peaceful, more responsible, and more thoughtful for the welfare of the human race than is her husband or brother.”

“There is no Animal in the general singular, separated from man by a single, indivisible limit. We have to envisage the existence of “living creatures,” whose plurality cannot be assembled within the single figure of an animality that is simply opposed to humanity. … The confusion of all nonhuman living creatures within the general and common category of the animal is not simply a sin against rigorous thinking, vigilance, lucidity, or empirical authority, it is also a crime. Not a crime against animality, precisely, but a crime of the first order against the animals, against animals.”

“I wonder whether there is such a thing as a sense of individuality. Is it all a facade, covering a deep need to belong? Are we simply pack animals desperately trying to pretend we are not?”

“it is all very well for you to write simply and the simpler the better. But do not start to think so damned simply. Know how complicated it is and then state it simply.”

“In general, most animals are exclusively breast-fed until they have tripled their birth weight, which in human infants occurs around the age of one year. In no mammalian species, except for the human (and the domestic cat), is milk consumption continued after the weaning period. Calves thrive on cow milk. Cow milk is for calves.”

“The philosophies of this world have all been framed by, and from the standpoint of, a single species, and they are still managed and maintained in the interests of this species.”
