Primates are very territorial. It is in their nature to protect their food resources as well as their females and young.

The chimps' way of aggression is quick and brutal. I compare them to gang attacks.

Only if we understand, can we care. Only if we care, we will help. Only if we help, we shall be saved.

What you do makes a difference, and you have to decide what kind of difference you want to make.

There isn't a sharp line dividing humans from the rest of the animal kingdom. All the time, we find animals doing things that, in our arrogance, we thought were just human.

Words can enhance experience, but they can also take so much away. We see an insect and at once we abstract certain characteristics and classify it - a fly. And in that very cognitive exercise, part of the wonder is gone. Once we have labeled the things around us we do not bother to look at them so carefully. Words are part of our rational selves, and to abandon them for a while is to give freer reign to our intuitive selves.

It made me feel particularly sickened to know that this kind of callous attitude toward animals is repeated again and again in laboratories around this country.
