My bad. I didn't make it clear that the "other 7" were simply the remaining ones already cited in my list but short of the 6 who make the cut (Urukagina, Moses, Buddha, Confucius, Socrates, Christ) according to the four criteria I submitted. Thus, the remaining 7 are Krishna, Wen Wang, Hesiod, Zarathustra, Lao-tze, Mohammed and Bahá’u’lláh. It is entirely likely that a few of these 7 may have been just as worthy as any of the six who make the cut. It's just that our documentation on them is simply too insufficient in certain cases for us to be as sure of them as we can be of the other 6.
