It was both fascinating and appalling to learn that chimpanzees were capable of hostile and territorial behavior that was not unlike certain forms of primitive human warfare.

Other people have talked about chimpanzees being a window into the past, which I suppose is true, in a way.

One individual cannot possible make a difference, alone. It is individual efforts, collectively, that makes a noticeable difference - all the difference in the world!

I think the most important thing is to keep active, and to hope that your mind stays active.

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?

Is it not possible that the chimpanzees are responding to some feeling like awe? A feeling generated by the mystery of water; water that seems alive, always rushing past yet never going, always the same yet ever different. Was it perhaps similar feelings of awe that gave rise to the first animistic religions, the worship of the elements and the mysteries of nature over which there was no control? Only when our prehistoric ancestors developed language would it have been possible to discuss such internal feelings and create a shared religion.

We seem to have lost the wisdom of the indigenous people, which dictated that in any major decision, the first consideration was 'How will this decision we're making today affect our people in the future? These days, decisions are made based on the bottom line.
