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.
There are viable (and usually better) alternatives to the use of animals for food, sport, clothing, & experimentation. I beg you to discontinue any actions that might cause or condone animal torture, abuse, or destruction.
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.
To those people who say, 'My father is alive because of animal experimentation,' I say, 'Yeah, well, good for you. This dog died so your father could live.' Sorry, but I am just not behind that kind of trade-off.
This isn't animal experimentation, where you an imagine some proportionate good at the other end of the suffering. This is what we feel like eating. Tell me something: Why is taste, the crudest of our sense, exempted from the ethical rules that govern our other sense? If you stop and think about it, it's crazy. Why doesn't a horny person has as strong a claim to raping an animal as a hungry one does to killing and eating it?
