Professor Vinay Lal "is a cultural critic, historian, scholar and writer who divides his time between Los Angeles and New Delhi. He writes widely on the history and culture of colonial and modern India, popular and public culture in India (especially cinema), historiography, the politics of world history, the Indian diaspora, global politics, contemporary American politics, the life and thought of Mohandas Gandhi, Hinduism, and the politics of knowledge systems." [From Wikipedia.]

In this impassioned lecture bubbling with insights (and red meat for leftists), he discusses the "imperialism of categories", i.e., the taxonomy of classifications, analyses, and judgments that postcolonial societies have adopted wholesale from the West. He then talks about what one can do by way of resistance and alternative conceptions (see also my related essay). On his blog, Lal Salaam (leftist pun surely intended), he probes in more detail the issues raised in this lecture. This was part of a 2010 meeting that "brought together academics and activists from around the world to share their experiences in understanding and resisting Western hegemony in various areas, including agriculture, education, health care, history, media, politics and science." Many other lectures are archived here but I haven't seen any yet.
