The indifference, callousness and contempt that so many people exhibit toward animals is evil first because it results in great suffering in animals, and second because it results in an incalculably great impoverishment of the human spirit.
He hath not eat paper, as it were; he hath not drunk ink; his intellect is not replenished; he is only an animal, only sensible in the duller parts. (Shakespeare, Love's Labor's Lost, IV)
human animals and nonhuman animals can communicate quite well; if we are brought up around animals as children we take this for granted. By the time we are adults we no longer remember.
To all the world he was the man of violence, half animal and half demon; but to her he always remained the little wilful boy of her own girlhood, the child who had clung to her hand. Evil indeed is the man who has not one woman to mourn him.
HELPED are those who love all the colors of all the human beings, as they love all the colors of the animals and plants; none of their children, nor any of their ancestors, nor any parts of themselves, shall be hidden from them.
The animal man lives in the senses. If he does not get enough to eat, he is miserable; or if something happens to his body, he is miserable. In the senses both his misery and his happiness begin and end.

The fish in the water is silent, the animals on the earth is noisy, the bird in the air is singing. But man has in him the silence of the sea, the noise of the earth and the music of the air.
A critic recently described me, with deadly acuteness, as having 'a kindly dislike of my fellow-creatures.' Perhaps dread would have been nearer the mark than dislike; for man is the only animal of which I am thoroughly and cravenly afraid.
I have been studying the traits and dispositions of the "lower animals" (so called) and contrasting them with the traits and dispositions of man. I find the result humiliating to me.
