"Perhaps this is an opportune moment to reveal my own present position on the Indo- European problem. I am one of a long list of people who do not believe that the avail- able data are sufficient to establish anything very conclusive about an Indo-European homeland, culture, or people. I am comfortable with the assumptions that cognate languages evolve from a reasonably standardized protoform (provided this is allowed con- siderable dialectal variation) that was spoken during a certain period of human history and culture in a somewhat condensed geographic area that is probably somewhere in the historically known Indo-European-speaking area (although I know of no solid grounds for excluding the possibility that this protolanguage could have originated outside of this area)."
