If not, then I must account for my willingness to believe she is still Stella but my rejection of Evil Megalos Stella. I must say that the same loop of awareness regenerated is the same woman—which I would—but if I say that and I have additionally already denied the necessity of the physical sameness of Stella’s body, I must own that here, if the loop is the same as the old one, the woman is also, and Stella could live again. If the loop were imperfect—if Evil Megalos Stella is functionally different, or if resuscitated Stella were changed by her experience, then she might be only 20 per cent Stella, or 30. Must I require all of Stella? She would have changed in the intervening years in any case. Shall I say she must be the woman she was at twenty for ever? No. What percentage of Stella, then, must inhabit the new loop before I can accept that she is herself? More or less than 50 per cent? If Stella had been in an accident and lost her memory, would I have disowned her, or sought to help her regain what she was? Should I do less now? I know the new woman would not be Stella, and yet why do I know it? Our minds are formed by the languages and cultures we inhabit. There are peoples who cannot see the difference between green and blue, peoples for whom numbers greater than two are a confusion of the mind. What blind spots do I have, in consequence of the frame in which I have always believed? Might I look through Stella, call her an impostor, out of nothing more than a learned prejudice?
