"I trust I may be forgiven for not coming to a clear conclusion myself. Until the script is deciphered, the presently available data are not sufficient to resolve the issue in my mind. The Indo-European languages came from somewhere between the Caspian Sea area (and the Balkans) and northwest South Asia. I do not feel impelled to favor any particular area in this vast expanse: all homeland proposals (not least of all South Asian ones) have significant problems, as I have attempted to outline throughout this work. The Indigenous Aryan critique has certainly influenced my own agnosticism."
