I think the most important thing is to keep active, and to hope that your mind stays active.

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.

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.

You aren't going to save the world on your own. But you might inspire a generation of kids to save it for all of us. You would be amazed at what inspired children can do.

If you work hard and be persistent, you will achieve whatever you want to do.

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 understood why those who had lived through war or economic disasters, and who had built for themselves a good life and a high standard of living, were rightly proud to be able to provide for their children those things which they themselves had not had. And why their children, inevitably, took those things for granted. It meant that new values and new expectations had crept into our societies along with new standards of living. Hence the materialistic and often greedy and selfish lifestyle of so many young people in the Western world, especially in the United States.
