If only we can overcome cruelty, to human and animal, with love and compassion we shall stand at the threshold of a new era in human moral and spiritual evolution - and realize, at last, our most unique quality: humanity.

When I began in 1960, individuality wasn't an accepted thing to look for; it was about species-specific behaviour. But animal behaviour is not hard science. There's room for intuition.

The only possible way to get somebody to change is to reach into their hearts.

Every stage of my life set the scene for the next, and at each point all I had to do was say "yes" and not think too much about the consequences.

As thy days, so shall thy strength be.

The voice of the natural world would be, "Could you please give us space and leave us alone to get along with our own lives and our own ways, because we actually know much better how to do it then when you start interfering."

People say, "Oh, we ought to fight for animal rights." We fought for human rights, but even if humans have rights, they can still be horribly abused and are every day. You don't have to go to some far off land, far away place; we have a lot of child abuse in our own society.
