I cannot remember a time when I did not want to go to Africa to study animals.

I learnt from Flo how to be mother. Flo was patient, tolerant. She was supportive. She was always there. She was playful. She enjoyed having her babies, as good mothers do.

I don't care two hoots about civilization. I want to wander in the wild.

Science demands objective factual evidence - proof; spiritual experience is subjective and leads to faith.

We, as humans, have actually developed a sense of social responsibility. We have gone beyond our basic instincts. We can and we do. This is what sets us apart from the chimps. They are extremely brutal and hostile. Your next door neighbor is to be killed unless she is a juicy young female, who hasn't yet had her first baby, in which case you want her.

Never be arrogant or abrasive. Treat your opponent respectfully if they really and truly believe they are right.

I just have this absolute belief that humans are moving away from cruelty and destruction towards a time when we can truly live in harmony with nature. When we understand that there is a spiritual power around us from which we can draw strength. That is where I believe human destiny ultimately is taking us. I just hope we have time.
