A postcolonial model is ironically extremely Eurocentric, with a total blindness to what came before Europeans.
This varies, of course, with the postcolonialist in question, but I wouldn't characterize it as ironic. The modern world arose as a result of a particular (Western) imperial/colonial long event - or at least it did if postcolonialists are anything close to correct - and people living in global south are just as much the inheritors of that legacy as those living in the north. So postcolonialism certainly does take a modern perspective, not those of imperial Malinese bureaucrats, Nahua mercenaries, or for that matter Carolingian knights. But it doesn't pretend to, any more than characteristically "northern" ideologies like liberalism do.
I have to run to class, but I can expand on this later if it's at all unclear (which self-calibrating has taught me my writing is oftentimes.)
Expand, please. Assuming the modern world stems from a colonial long event, why would that imply that "a total blindness to what came before Europeans" is only to be expected? Or, say (if we tone down the hyperbole a little) a large degree of blindness.
