The internal consistency of Orientalism is one of its most salient features—indeed, it is the basis for a large part of Said’s argument that Orientalism is a discourse rather than the neutral academic enterprise as which it has historically understood itself.

Orientalism to become an uncritical discourse themselves. Instead, he encourages others to grapple with, challenge, and expand his ideas in the future.
