I am not interested to know whether vivisection produces results that are profitable to the human race or doesn't...The pain which it inflicts upon unconsenting animals is the basis of my enmity toward it, and it is to me sufficient justification of the enmity without looking further.
Animal experimentation is the blackest of all the black crimes that a man is at present committing... We should be able to refuse to live if the price of living be the torture of sentient beings... I abhor [animal] experimentation with my whole soul. All the scientific discoveries stained with innocent blood I count as of no consequence... The greatness of a nation and its moral progress can be judged by the way its animals are treated.
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.
Perhaps it is the lowest of the qualities of an orator, but it is, on so many occasions, of chief importance,--a certain robust and radiant physical health; or--shall I say?--great volumes of animal heat.
MAMMALIA, n.pl. A family of vertebrate animals whose females in a state of nature suckle their young, but when civilized and enlightened put them out to nurse, or use the bottle.

The fly ought to be used as the symbol of impertinence and audacity; for whilst all other animals shun man more than anything else, and run away even before he comes near them, the fly lights upon his very nose.
The animal lacks both anxiety and hope because its consciousness is restricted to what is clearly evident and thus to the present moment: the animal is the present incarnate.
The policy of man consists, at first, in endeavoring to arrive at a state equal to that of animals, whom nature has furnished with food, clothing, and shelter.
Quadruped lions are said to be savage, only when they are hungry; biped lions are rarely sulky longer than when their appetite for distinction remains unappeased.
If there is any kind of animal which is female and has no male separate from it, it is possible that this may generate a young one from itself. No instance of this worthy of any credit has been observed up to the present at any rate, but one case in the class of fishes makes us hesitate. No male of the so-called erythrinus has ever yet been seen, but females, and specimens full of roe, have been seen. Of this, however, we have as yet no proof worthy of credit.
