I have found that to love and be loved is the most empowering and exhilarating of all human emotions.

There are good mothers and bad ones, but most of them are somewhere in-between.

One thing I had learned from watching chimpanzees with their infants is that having a child should be fun.

I see that within each human being there are two extremes: there's the loving, the passionate, altruistic side that has evolved with us, and then there's the violent, brutal side that has evolved with us. The question for each individual is: which side is going to come out on top?

You have to realise that touching is a real violation of personal space.

The most important thing is to actually think about what you do. To become aware and actually think about the effect of what you do on the environment and on society. That's key, and that underlies everything else.

A chimp would never plan to pull another's nails out.
