Control is the source of strategic power.

I did not say that language as a completed system emerged in an individual in an instant. But I cannot think of a coherent alternative to the idea that mutations take place in individuals, not communities, so that whatever rewiring of the brain yielded the apparently unique properties of language, specifically recursive generation of hierarchically structured expressions, would therefore have taken place in an individual, and only later been used among individuals who had inherited this capacity.

If you go to one demonstration and then go home, that's something, but the people in power can live with that. What they can't live with is sustained pressure that keeps building, organisations that keep doing things, people that keep learning lessons from the last time and doing it better the next time.

The House of Representatives, which was closer to the population, had much less power. The executive was more or less an administrator, not an emperor like today.

While language can surely be used for communication (as can much else), communication probably has no special role in its design or evolution.

That's the whole point of good propaganda. You want to create a slogan that nobody's going to be against, and everybody's going to be for. Nobody knows what it means, because it doesn't mean anything.
