Because in his model 1781 was a biological break, not only a cultural one. Ra says that as far as he can tell, Homo sapiens came to an end in 1781, and he calls the form since then a Homo sapiens interregnum, neither the old human nor yet what it is meant to house. Later he makes it personal: you have nothing in common with anyone born before 1781, you are wired differently and biologically different, whatever the surface similarity. His reasoning runs through the tones: in the seven centered ancestors the left, strategic side was rooted in the splenic binary, whose task is to keep the form alive, so their awareness was entirely about survival, defense, food and procreation. He adds, and this matters, that only in this nine centered form is it possible to awaken and to be correct. So the claim is less a put down of our ancestors than an argument for why Strategy and Authority are new tools for a new vehicle.
