Researchers find it very necessary to keep blinkers on. They don't want to admit that the animals they are working with have feelings.

But let us not forget that human love and compassion are equally deeply rooted in our primate heritage, and in this sphere too our sensibilities are of a higher order of magnitude than those of chimpanzees.

The more we learn of the true nature of non-human animals, especially those with complex brains and corresponding complex social behavior, the more ethical concerns are raised regarding their use in the service of man - whether this be in entertainment, as "pets," for food, in research laboratories, or any of the other uses to which we subject them.

I like some animals more than some people, some people more than some animals.

I'm always pushing for human responsibility. Given that chimpanzees and many other animals are sentient and sapient, then we should treat them with respect.

If you look into their [chimpanzees] eyes, you know you're looking into a thinking mind. They teach us that we are not the only beings with personalities, minds capable of rational thought, altruism and a sense of humor. That leads to new respect for other animals, respect for the environment and respect for all life.

Realize that change - whilst we want it to happen fast - is usually the result of a great deal of work, and often comes as a result of a series of compromises (so long as we do not compromise our values).
