- Sitting Bull
Maria Corte Maidagan

"All animals, except man, know that the principal business of life is to enjoy it."
- Samuel Butler
"On the intimate level, anyone who has loved a companion animal knows the uniquely wonderful experience these 'other nations' provide, and their important presence in our shared lives. In their very local way they show us the global truth of our real wealth, our biodiversity."
- April Gornik
"All animals are equal, but some animals are more equal than others."

- Christopher McDougall
"An animal's eyes have the power to speak a great language."

- Mikhail Bakunin
"In the animal world, there are all kinds of behaviors that are binary: for example, to flee or to fight. In any evolutionary environment, knowing your opponent's decision would not be advantageous for long because your opponent would evolve the same recognition mechanism to also know you."
- Chris Adami
"Goats are the cable talk show panelists of the animal world, ready at a moment's notice to interject, interrupt, and opine. They have something to say about everything, little of it complimentary. They are the most impertinent animals I have ever known."
- Jon Katz

"Some kinds of animals burrow in the ground; others do not. Some animals are nocturnal, as the owl and the bat; others use the hours of daylight. There are tame animals and wild animals. Man and the mule are always tame; the leopard and the wolf are invariably wild..."
"I think that intelligence is such a narrow branch of the tree of life - this branch of primates we call humans. No other animal, by our definition, can be considered intelligent. So intelligence can't be all that important for survival, because there are so many animals that don't have what we call intelligence, and they're surviving just fine."
- Neil deGrasse Tyson
"Cows are gentle, interesting animals."
- Ingrid Newkirk
"A kitten is in the animal world what a rosebud is in the garden."
- Robert Southey
"When we see animals doing remarkable things, how do we know if we're simply seeing tricks or signs of real intelligence? Are talented animals just obeying commands, or do they have some kind of deeper understanding? One of the biggest challenges for animal researchers is to come up with tests that can distinguish between the two."
- Neil deGrasse Tyson
"The animal kingdom is destined by nature to serve, and that service is fulfilled in alleviating the temporal and physical needs of man; the animal spirit or soul is limited by time - it dies with the body."

"Closeness to animals creates the desire to understand them, and not just a little piece of them, but the whole animal. It makes us wonder what goes on in their heads even though we fully realize that the answer can only be approximated."
- Frans de Waal
"Whenever you observe an animal closely, you feel as if a human being sitting inside were making fun of you."
- Elias Canetti
"It's really bizarre because no one knows this, but elephants have killed more animal trainers than any other animal."
- Vin Diesel
"Animals often strike us as passionate machines."
- Eric Hoffer
