We are unique. Chimpanzees are unique. Dogs are unique. But we humans are just not as different as we used to think.

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.

The problem of the chimps is that they can only sit and look. They can't discuss what they feel. All that feeling is trapped within each one.

Every single day, we could be in a motorcar accident, so, we have to carry on with our lives, and not imagine terror around every corner.

....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.

Just think of the trust that often exists in soldiers. Within their own unit, you could say they have to trust each other. A spirit of camaraderie builds up and, in the end, they will risk their lives for each other. They may even go so far as to dehumanise the other, enemy group - a mechanism you can also observe in chimps.

Cultural speciation had been crippling to human moral and spiritual growth. It had hindered freedom of thought, limited our thinking, imprisoned us in the cultures into which we had been born. . . . These cultural mind prisons. . . . Cultural speciation was clearly a barrier to world peace. 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.
