The least I can do is speak out for those who cannot speak for themselves.

"The first time I saw adult chimpanzees in these five-by-five foot cages... tears began to trickle down under my mask, and [JoJo, a chimp,] just reached out this gentle finger and wiped them away... And then the veterinarian came. He knelt down beside me and put his arm around me. He said, "I have to face this every day.

"If chimpanzees have consciousness, if they are capable of abstractions, do they not have what until now has been described as "human rights"? How smart does a chimpanzee have to be before killing him constitutes murder? What further properties must he show before religious missionaries must
consider him worthy of attempts at conversion?"

Them as can do has to do for them as can't. And someone has to speak up for them as has no voices.

The eyes of others our prisons; their thoughts our cages.

The nasty little apes that call themselves human beings can do nothing except run and hide.

We've had enough exhortations to be silent. Cry out with a thousand tongues - I see the world is rotten because of silence.

For animals that are overworked, underfed, and cruelly treated; for all wistful creatures in captivity that beat their wings against bars; for any that are hunted or lost or deserted or frightened or hungry; for all that must be put to death...and for those who deal with them we ask a heart of compassion and gentle hands and kindly words.

...two chimpanzees were observed maltreating a chicken: One would extend some food to the fowl, encouraging it to approach; whereupon the other would thrust at it with a piece of wire it had concealed behind its back. The chicken would retreat but soon allow itself to approach once again — and be beaten once again. Here is a fine combination of behavior sometimes thought to be uniquely human: cooperation, planning a future course of action, deception and cruelty.

If a curiously selective plague came along and killed all people of intermediate height, 'tall' and 'short' would come to have just as precise a meaning as 'bird' or 'mammal'. The same is true of human ethics and law. Our legal and moral systems are deeply species-bound. The director of a zoo is legally entitled to 'put down' a chimpanzee that is surplus to requirements, while any suggestion that he might 'put down' a redundant keeper or ticket-seller would be greeted with howls of incredulous outrage. The chimpanzee is the property of the zoo. Humans are nowadays not supposed to be anybody's property, yet the rationale for discriminating against chimpanzees in this way is seldom spelled out, and I doubt if there is a defensible rationale at all. Such is the breathtaking speciesism of our attitudes, the abortion of a single human zygote can arouse more moral solicitude and righteous indignation than the vivisection of any number of intelligent adult chimpanzees! [T]he only reason we can be comfortable with such a double standard is that the intermediates between humans and chimps are all dead.

Welcome folded arms, fixed eyes, a sigh that piercing mortifies; A look that's fastened to the ground, a tongue chained up without a sound.

On the National Executive sat Charles Clarke, looking like a rather manky chimpanzee with his unkempt beard, jug ears and his air of surly aggression.

There must be a great many of them here who think as I do, and we dare not say a word to each other out of our desperation, we are speechless animals letting ourselves be destroyed, and why? Does anybody here believe the things we say to each other?

Odd planet! The bipeds talked from their heads and only saw what lay before them. In short, they were pathetic — and deadly!
