“….the ‘Sanskrit-origin’ hypothesis runs into insurmountable difficulties, due to the irreversible nature of relevant linguistic changes [….but….] the likelihood of the ‘PIE-in-India’ hypothesis cannot be assessed on the basis of similar robust evidence” (HOCK 1999a:2), and that “The ‘PIE-in-India’ hypothesis is not as easily refuted as the ‘Sanskrit-origin’ hypothesis, since it is not based on ‘hard-core’ linguistic evidence, such as sound changes, which can be subjected to critical and definitive analysis. Its cogency can be assessed only in terms of circumstantial arguments, especially arguments based on plausibility and simplicity” (HOCK 1999a:12).

The aim should be not to “forestall all dissenting voices”, but (a) to “invite meaningful debate”; (b) “to invite the scholarly challenges and ensuing debate that can lead to better insights and closer approximation of the truth”; (c) “to go beyond what can be grasped at first contact, and as a consequence of having to defend perceptions against competing views, to investigate matters more thoroughly”; (d) to “approximate truth more closely”; (d) to “go beyond initial impressions and beyond the validation of preconceived interpretations”; (e) to “embrace the scientific approach of being transparent and vulnerable – transparent by being open to verification in terms of providing supporting evidence and discussing potentially conflicting evidence, and vulnerable by being open to challenge and potential falsification“; (f) “to evaluate the very different perspectives that are current and thus to reach beyond the differences in perspective, ideology or bias” (HOCK 2005:282-3).

He emphasizes an approach where truth is the “ultimate goal”, but “truth is always conditional, to be superseded by better evidence or interpretation of evidence” (HOCK 2005:282).
