One must beware of falling into a kind of uncritical Indological McCarthyism towards those open to reconsidering the established contours of ancient … - Edwin Bryant

In a progressive academic context, differences of opinions, however radical, challenge scholars to constantly reexamine their views, assumptions, and methods. This is the lifeline of healthy scholarship. But in the present academic climate in the subcontinent, it has become increasingly difficult, particularly for Indian scholars, to discuss the pre- history of the subcontinent in a rational, objective way without becoming associated with the ideologies that are immediately correlated with pro- or contra- stances for or against the Indigenous Aryan issue. This works to the obvious detriment of expanding and developing a nuanced understanding of the early history of the subcontinent.

Indeed, one might well wonder how much research would have been invested in the Indo-European problem in the first place, had it not been for its relevance to European imperialism and nationalism.

Many of die foreign terms for flora and fauna could simply indicate that these items have continually been imported into the subcontinent over the centuries, as continues to be the case today. The exception to this is place-names and river names, but the absence of foreign terms for the topography and hydronomy of the Northwest deprives us of significant evidence that has been used to establish substrata elsewhere.
