The female covers her breasts, and then proceeds to redefine their shape with a brassiere. This sexual signaling device may be padded or inflatable, so that it not only reinstates the concealed shape, but also enlarges it, imitating in this way the breast swelling that occurs during sexual arousal.

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

No matter how old we become, we can still call them 'Holy Mother' and 'Father' and put a child-like trust in them.

Looking back now on the whole sexual scene we can see that our species has remained much more loyal to its basic biological urges than we might at first imagine. Its primate sexual system with carnivore modifications has survived all the fantastic technological advances remarkably well.

This unusual and highly successful species spends a great deal of time examining his higher motives and an equal amount of time ignoring his fundamental ones.

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.

...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.
