colonialism - that on the one hand, orientalist scholarship (described by Said as "manifest orientalism") developed from the eighteenth century as a means of justifying the process of imperialist expansion, whilst on the other, a deeply ingrained tradition of broader orientalist depictions of the East stretching back to the classical era (which Said labelled "latent orientalism") played a role in creating the conditions for the launching of colonial projects. Whilst the first claim had previously been made by anti-colonial thinkers, the latter was novel. In the years after Orientalism was published, Said's arguments were critiqued by Sadiq Jalal al-Azm and Aijaz Ahmad. In 1981 Al-Azm suggested that conceiving of orientalism as "the natural product of an ancient and almost irresistible European bent of mind to misrepresent the realities of other cultures, peoples, and their languages, in favour of Occidental self-affirmation" served to reinforce the essentialism that was at the heart of orientalism, rather than challenging it, i.e. that the West is inherently incapable of understanding the East. Just over ten years later Ahmad raised two criticisms of Said's assertions: firstly, that according to Said orientalist views were so pervasive that he did not differentiate critics of colonialism such as Karl Marx from supporters of imperialism, despite the role of Marxists in anti-colonial struggles across the world, and secondly that Said's suggestion of cultural causes for imperialism displaced older Marxist, nationalist and liberal analyses based on the interests of economic classes, nations and individuals in favour of a "Clash of Civilizations" thesis. More recently, Chibber has pointed out that essentialist and ethnocentric portrayals of foreign cultures can be found in pre-colonial Eastern civilisations as well: whilst Said acknowledged that "all cultures impose corrections upon raw reality", Chibber has argued that this fact weakens the contention that such essentialism was itself a cause of colonialism, since the latter was practiced by a relatively small number of mostly Western European countries. Regarding a weaker interpretation of Said's thesis - that latent orientalism was a necessary but not sufficient prerequisite for colonialism - Chibber contends that economic and political factors are universally accepted as contributory causes of colonialism, that these in themselves would generate pressure for arguments to legitimise imperial projects, and therefore a case cannot be made that pre-existing latent orientalism was indispensable for the rise of colonialism.
