If you look through all the different cultures. Right from the earliest, earliest days with the animistic religions, we have sought to have some kind of explanation for our life, for our being, that is outside of our humanity.

We could change the world tomorrow if all the millions of people around the world acted the way they believe.

My mother always taught us that if people don't agree with you, the important thing is to listen to them. But if you've listened to them carefully and you still think that you're right, then you must have the courage of your convictions.

If we do not do something to help these creatures, we make a mockery of the whole concept of justice.

So long as we continued to attach more importance to our own narrow group membership than to the 'global village' we would propagate prejudice and ignorance. There was absolutely no harm in being part of a small group - indeed, with our hunter-gatherer band mentality it gave comfort, provided us with an inner circle of friends who could be utterly trusted, who were absolutely reliable. It helped give us peace of mind. The danger came only from drawing that sharp line, digging that ditch, laying that minefield, between our own group and any other group that thought differently.

Young people, when informed and empowered, when they realize that what they do truly makes a difference, can indeed change the world.

But let us not forget that human love and compassion are equally deeply rooted in our primate heritage, and in this sphere too our sensibilities are of a higher order of magnitude than those of chimpanzees.
