Edward Said’s signature contribution to academic life is the book Orientalism. It has been influential in about half a dozen established disciplines, especially literary studies (English, comparative literature), history, anthropology, sociology, area studies (especially middle east studies), and comparative religion. However, as big as Orientalism was to academia, Said’s thoughts on literature and art continued to evolve over time, and were encapsulated in Culture and Imperialism (1993), a book which appeared nearly 15 years after Orientalism (1978).
Put highly reductively, the development of his thought can be understood as follows: Said’s early work began with a gesture of refusal and rejection, and ended with a kind of ambivalent acceptance. If Orientalism questioned a pattern of misrepresentation of the non-western world, Culture and Imperialism explored with a less confrontational tone the complex and ongoing relationships between east and west, colonizer and colonized, white and black, and metropolitan and colonial societies.
Said directly challenged what Euro-American scholars traditionally referred to as “Orientalism.” Orientalism is an entrenched structure of thought, a pattern of making certain generalizations about the part of the world known as the ‘East’. As Said puts it:
“Orientalism was ultimately a political vision of reality whose structure promoted the difference between the familiar (Europe, West, “us”) and the strange (the Orient, the East, “them”).”
Just to be clear, Said didn’t invent the term ‘Orientalism’; it was a term used especially by middle east specialists, Arabists, as well as many who studied both East Asia and the Indian subcontinent. The vastness alone of the part of the world that European and American scholars thought of as the “East” should, one imagines, have caused some one to think twice. But for the most part, that self-criticism didn’t happen, and Said argues that the failure there –- the blind spot of orientalist thinking –- is a structural one. (Source)
