"Instead of letting us know definitely and precisely where the so-called original home of the Aryans lay, they drag us into a maze of conjectures clouded by the haze of presumptions. The whole subject of the Aryan problem is a farrago of linguistic speculations or archaeological imaginations complicated by racial prejudices and chauvinistic xenophobia. It is high time we extricate ourselves from this chaos of bias and belief."
