Because the rules of this society were principally those of the females who kept the home together, the men began to become more and more prone to feelings of guilt about their competitive hunting lifestyle. They weren’t actually doing anything wrong (they were taking care of aspects of the needs of the group) but it felt wrong. And the more wrong they felt, the more insecure they became, and the more insecure they became the angrier they became and thus the more destructive they became, and then they really were doing things which they could see were doing harm to the group. And so on and so on. Stopping the process would have required either explaining to themselves and the women what was happening, which they didn’t yet have the insight to do, or saying they were wrong which they knew was not the case. If they didn’t defy the implication that they were in the wrong they would have collapsed into a state of inoperable self-contempt or depression. The more insecure and condemned they felt the more angry and egotistical and defiant they became, and armouring was the form that this took in the shape of their personalities. The initial substance with which we built our armour was repressed anger. This is why, when the armour is compromised, a release of anger or even violence is the result.

Over time, the whole of the group became insecure and armoured. Hostility within the group and the strain of desperately trying to use sex to socialise the men put a strain on the women and compromised the nurturing of the children. We all ended up getting hurt. And, in our pain, we turned within and began to build a wall that we thought would keep us safe.

As we males became more and more egotistical and more fragile in our sense of ourselves, drastic changes in social behaviour had to take place in order to hold the group together.

This was the origin of monogamy. The only way to keep men from fighting over the sexual favours of women was to institute strict controls on sexual behaviour.

Of course this meant that both men and women had to adopt sexual repression. We could no longer simply do what we wanted when it came to our sexual behaviour. But the desires were not gone. We still wanted to have sex with different people, but we had to push those desires down and contain them. In this way, repressed sexual desires became a part of the substance of our armouring in the same way that repressed aggressive feelings had become before this.

This is when fear of sex became a significant part of our psychology and our society. When we were not armoured, sex had been an unthreatening and pleasant part of our lives, and something which was beneficial to our society.

But the armoured personality and the armoured society are built on sexual repression. Erotic feelings are essentially anarchic and could bring the whole thing down. And, unrestrained sexual behaviour in an armoured society leads to social conflict. We keep it all together by not sleeping with each other’s partners and not confronting people with sexual arousing material which might make it hard for them to maintain their self-discipline.

Because our tertiary sexual drive is to reunite with the disowned part of our own nature, we came to select sexual partners whose appearance reminded us of our original state. This is how we developed our concept of female beauty. What we tend to think of as classical beauty is childlike features such as wide eyes, full lips, a slim build, and, in our originally hairy days, this included a shortage of hair. And so this is how we lost our hair. This is called selection for neotony and it explains why we look more like a chimpanzee foetus than we do like a full-grown chimp.
