At the risk of straying too far from Trautmann's (1997) analysis of the racialization of the study of ancient Indian civilization (including plenty of interesting discussion of noses!), I was most struck by Trautmann's (2005) discussion of the politics of the current aryan debate in India. As an archivist-to-be, I'm continually aware of the degree to which the archivist creates -- and I mean this is a much stronger and more intrusive process than simply shaping -- the historical record. Although the processes of appraisal, arrangement and description are deeply interpretive, they are taught and practiced as though they were natural and blindly procedural. This results in the reproduction of particular views of the past, the preservation of evidence that follows the received wisdom, and the discarding of other evidence that is precieved by the archivist as irrelevant, unhistorical, or white noise.
Historians often continue this rather conservative method of interpreting the past. Indeed, "facts only become significant facts for history in respect of some general view of things, some intellectual paradigm," and the professionalization of the study of history is often responsible for crystalizing a particular intellectual viewpoint.
This is why I find it exciting that persons outside of archeology, linguistics and history take a stake in the aryan debate (although they are of course not exempt from the same intellectual paradigms -- but they may offer a more diverse view). I am aware, however (although Trautmann treads lightly here, out of a sense of fairness, I assume) that the motivations behind some of those who advocate the "alternative view" are not necessarily politically benign and that their conclusions are not deliberated with the same degree of expertise and training as that of sober academics.
Trautmann says that "... the truth of ancient history is indifferent to our wishes, our politics, our religion, in short, our own social and historical location. The idea of truth in history involves the idea that it exists independent of our will, and is therefore inherently difficult to know, because our interpretations are will-bound, and our facts are never independent of our theories." This, I think, is fascinating, because it speaks to our motivations for studying a particular subject -- while the aryan debate in the public sphere, with its loud voices and ill-considered opinions obfuscates historical study, it also fuels historical study and draws attention to a subject that might be otherwise considered irrelevant.
