Gayatri Chakravorty Spivak at the University of Ghana

I saw Spivak speak this morning. I found her presentation much more interesting than I thought I would. First, I agree with her that culturally based nationalism is a problem rather than a solution for the most part. Although I do not know enough about the specifics of Indian history to comment too much on her main examples. I did find it very interesting that she compared the descendants of the Aryans in India to settler colonies elsewhere. I have never heard this particular theory and the comparison struck me as quite unusual. But, again I don't know enough to say whether it is valid or not. Maybe somebody with more knowledge of Indian history than I have can enlighten me on this point?
