In my humble opinion what Norman is realy saying is that the strong should take the responsibility to keep those in thier dominion in the best way possible so that the whole thrives as opposed to allowing the system to run itself blindly with no guildence into corruption.
It does sugest and rightly so as history can attest that Men are more predetermined to dominant in this regard and that all females may have a biologically predisposed orientation to then submit to those that prossess those traits of virility that are desireable in a mate. (Otherwise for the vast majority of known history patriarchial societies would not have flourished nor would the vast majority of women preffer strong intellgent men for mates as opposed to frail weak willed individuals they can easily dominate) Hence the bilogical essence of the philosophy sugested by Norman.
He also says that any woman in question will not submit to that which she can dominante herself. That in effect if she is refused the dominance her biological inner self may crave she will quickely replace it with her own and with verve. Thus explaining much of the animosity we see in marriges today.
The message is simple in the regard of explaining how a hierarchy of dominion exists not only on "Gor", but here on earth as well.
The difference here is that the men have in general allowed themselves to become far weaker willed with time and a large degree of role reversal as come to the fore.
It is really in many ways a plea for men to become men again as much as it is an explanation of why we as human beings are the way we are.
