The way of it is this; it both illustrates the problem and the solution within society. It points out that shifts from one society to another occur due to specific reasons. It also shows that in order to create a stable society what some of the steps are for creating a stable society. It shows in my eyes the paradox in what we term society. Without consensus within a society of what is "right", doing your "little fixes" is counterproductive. Why? The reason is because you have one set of people thinking one way is right while another group thinks the complete opposite is right. Which results in no change, or the stronger side dominating the other. That is not consensus, but "might makes right".
I don't mean to show that L.E. Modesitt Jr.'s stuff is the endall be all of anything, just that it outlines the problem and solution to creating a stable society, with most ideals it is hard to put into practice. Anyhow, <shrugs> take what you will...
