The "third" world is not and cannot be represented in its own terms, for in "first" world imperializing knowledge there are no such things: its mode of representation is a "first" world product which reproduces the "first" world in all that it represents.
This reminds me of how imperialism in the past was justified. If a country and their people were taken over, the justification was that they were "doing the right thing" or "helping them out". In reality, it was purely expansion of their own country and showing superiority to others.
