What's wrong with historical clades of doctrine? How is that different from "Enlightenment values?" (Other than one having a theological origin.)
An example of thinking about causality would be the French decision to cede Saint-Domingue its independence. Critics (inherently conservative) of this decision would postulate one kind of future for the new Haiti; proponents (inherently revolutionary) would postulate quite another. Of course, at the time this or any similar such decision had large numbers of very eloquent critics and proponents; so their arguments are easily discovered, if not obvious already.
So their arguments establishing a causal chain back to a certain system of values is too long to summarize here? I think you'd be able to explain, or I've caught you out with a fallacious tactic for winning forum arguments by tarring opponents with Cabrini Green.
So as far as I can tell, you claim to determined that either revolutionaries or conservatives are simply bad news and you're promulgating a historical science that shows this. I'm still not clear on where the causal chain is established in all this back to a certain set of values.
It's a shame most people don't decide what historical ideologies are "discredited" by a rigorous and objective standard such as this.
I still don't see what's rigorous and objective yet. There's almost always a significant difference between people's stated values and their practiced values. This has often been noted by anthropologists.
Instead, the standard is the inevitable one: the winner is always right. This is the simple, yet remarkably practical, basis on which our supposedly rational faith in the Enlightenment rests.
Why is the standard the inevitable one? I think it's partly because it's all a chaotic mishmash. Almost no one lives up to their stated values, especially those who govern, and most of the evil that happens is rooted in great part in basic human nature.
