First, it is the function of scholarship to establish and promote true knowledge so that our life be regulated by this – not prejudices, partisan vie… - Nikos Kazanas

I start with some literary evidence. RV 4.1.13 & 4. 2.16 the Angirases declare that their ancestors made sacrifices “here” atra, ie in Saptasindhu. 3.53.11 Sudās fought enemies prāk ‘east’, apāk ‘west’ and udāk ‘north’ only, but not south. So we have no Indoaryans coming from the north and driving natives southward. The movement here is from east westward (apāk) and from south northword (udāk)! M6.61.9,12: Sarasvatī, the Rivergoddess, spread all five tribes beyond the other seven sister-rivers as the sun spreads out the days – again, days and sunlight from the east! 7.6.3 Agni turned the unholy Dasyus from east to west –pūrvaś cakāra áparām! Notice – NOT SOUTH (avāk or nyāk).

From a very long experience of reading, studying and teaching, of participating in Conferences and, in recent years, of editing articles for Journals (and, of course, private contacts and exchanges with scholars in many fields) I acquired the certainty that very few academics use their reason to the full and even fewer are, despite their vociferous protestations to the contrary, interested in truth.

Copernicus, Kepler and Galileo were ‘revisionists’ in rejecting the geocentric system of Ptolemy (which held sway for some 1500 years) and, against an oppressive and repressive mainstream opinion (and officialdom), reinstated—with improvements—the heliocentric system of Aristarchos of Samos (3rd cent BCE).
