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.
If it's a question about stuff that matters to you personally, like favorite food, favorite piece of knowledge, favorite animal, it's hard not to have an opinion and want to quantify things.
Compassion for animals is intimately associated with goodness of character, and it may be confidently asserted that he who is cruel to animals cannot be a good man.
How can you say you're trying to spiritually evolve, without even a thought about what happens to the animals whose lives are sacrificed in the name of gluttony?
All are agreed that the various moral qualities are in a sense bestowed by nature: we are just, and capable of temperance, and brave, and possessed of the other virtues from the moment of our birth. But nevertheless we expect to find that true goodness is something different, and that the virtues in the true sense come to belong to us in another way. For even children and wild animals possess the natural dispositions, yet without Intelligence these may manifestly be harmful.
Without enough wilderness America will change. Democracy, with its myriad personalities and increasing sophistication, must be fibred and vitalized by regular contact with outdoor growths - animals, trees, sun warmth and free skies - or it will dwindle and pale.
The aim of education is to make the pupil like and dislike what he ought....The little human animal will not at first have the right responses. It must be trained to feel pleasure, liking, disgust, and hatred at those things which really are pleasant, likable, disgusting, and hateful.
The perfect woman is a higher type of humanity than the perfect man, and also something much rarer. The natural history of animals furnishes grounds in support of this theory.
There is no character, howsoever good and fine, but it can be destroyed by ridicule, howsoever poor and witless. Observe the ass, for instance: his character is about perfect, he is the choicest spirit among all the humbler animals, yet see what ridicule has brought him to. Instead of feeling complimented when we are called an ass, we are left in doubt.
What strength belongs to every plant and animal in nature. The tree or the brook has no duplicity, no pretentiousness, no show. It is, with all its might and main, what it is, and makes one and the same impression and effect at all times. All the thoughts of a turtle are turtle's, and of a rabbit, rabbit's. But a man is broken and dissipated by the giddiness of his will; he does not throw himself into his judgments; his genius leads him one way but 't is likely his trade or politics in quite another.
For the real difference between humans and other animals is that humans alone have perception of good and evil, just and unjust, etc. It is the sharing of a common view in these matters that makes a household and a state.
Let's stick to the practical and the concrete: Would you like it if people lived in a virtual world? If machines were smarter than people? If, in the future, people, animals and plants were products of technology? If you don't like these ideas, then for you the computer and biological sciences clearly are dangerous.
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.
