This is rather one-sided interpretation, but it definitely has its precedences in history and even in our times.
(FWIW I think he's got the wrong word. He says "For millenia, conservatism had no name..." and then cites divine right of kings.)
Moving forward with caution doesn't mean you absolutely don't trust others but they are the out-group, if we assume there are two groups here. Those others won't get the same benefit of the doubt as your in-group and thus any mistake they make will be magnified (in relative terms).
> For millenia, conservatism had no name, because no other model of polity had ever been proposed. “The king can do no wrong.” In practice, this immunity was always extended to the king’s friends, however fungible a group they might have been. Today, we still have the king’s friends even where there is no king (dictator, etc.). Another way to look at this is that the king is a faction, rather than an individual.
> As the core proposition of conservatism is indefensible if stated baldly, it has always been surrounded by an elaborate backwash of pseudophilosophy, amounting over time to millions of pages. All such is axiomatically dishonest and undeserving of serious scrutiny. Today, the accelerating de-education of humanity has reached a point where the market for pseudophilosophy is vanishing; it is, as The Kids Say These Days, tl;dr . All that is left is the core proposition itself — backed up, no longer by misdirection and sophistry, but by violence.
That is to say: the past is built around this one proposition. Moving forward "with caution" translates to "how can we move forward (solve some current problem) without jeopardizing this essential proposition?"
Can you help me connect the two or at least help me understand the underlying proposition?
