what are you talking about, many ancient phylosophers we considering some people as 'lesser' and we still hold them in high regard. Lol
''And concerning the listlessness and cowardice of peoples, the seasons are especially the cause why Asians are less martial than the Europeans and more tame in their character,for making no dramatic shift either to the hot nor to the cold their seasons are temperate. For there are no mental disturbances nor strong change of the body, from which it is more likely that the passion is roused and indulges the senseless and high-spirited rather than when it is in a steady state. For it is change of everything which wake the disposition of men and do not allow it to rest. For these aforesaid reasons it seems to me that that the Asian race is weak and yet further so because of their customs. For much of Asia is ruled by a king. And where men do not rule themselves nor are autonomous, but are ruled by a despot, there is no reason for them to concern themselves over this. So that they do not practice the military disciplines, but they work to seem pacifistic'' (Hippocrates, Airs, Waters, Places, XVI). (1)
''Therefore the poets say, “It is fitting that the Greeks rule barbarians,” on the grounds that the barbarian and slave are the same in nature'' (Politics 1252b7-9).
