It must be stressed that there is nothing insulting about looking at people as animals. We are animals, after all. Homo sapiens is a species of primate, a biological phenomenon dominated by biological rules, like any other species. Human nature is no more than one particular kind of animal nature. Agreed, the human species is an extraordinary animal; but all other species are also extraordinary animals, each in their own way, and the scientific man-watcher can bring many fresh insights to the study of human affairs if he can retain this basic attitude of evolutionary humility.

We never stop investigating. We are never satisfied that we know enough to get by. Every question we answer leads on to another question. This has become the greatest survival trick of our species.

We may prefer to think of ourselves as fallen angels, but in reality we are rising apes.

As long as the human race is able to concern itself with more than mere survival, soccer will have its place.

We read off the many signals that our companions' clothes transmit to us in every social encounter. In this way, clothing is as much a part of human body language as gestures, facial expressions and postures.Even those people who insist that they despise attention to clothing, and dress as casually as possible, are making quite specific comments on their social roles and their attitudes towards the culture in which they live.

We are to put it mildly, in a mess, and there is a strong chance that we shall have exterminated ourselves by the end of the century. Our only consolation will be that as a species, we have had an exciting term of office.

...In little more than a single century from 1820 to 19450, no less than fifty-nine million human animals were killed in inter-group clashes of one sort or another.... We describe these killings as men behaving "like animals," but if we could find a wild animal that showed signs of acting this way, it would be more precise to describe it as behaving like men.
