If you’re writing a novel (novel-writing is not a subfield of rationality) then you don’t need to keep in mind the principle “[i]f you don’t understand an idea’s limitations then you don’t understand that idea.”
On the other hand, if you are trying to figure out whether Capitalism is the best ideological framework to apply to a region (which is a question within the domain of rational analysis) then you absolutely must keep in mind the limits of the Capitalist framework.
I can give a concrete example.
