Yeah , I ' ll ask around and see if I can ' t find more info about specific time frames but the clue tracker has really put into perspective for me anyways the amount of clues people do on a regular basis . 100 , 000 Master Clues alone since release . Pretty outstanding . <| sep |> Species membership doesn ' t matter morally , of course . Personhood is about properties which supervene on the biology but are not grounded in those biological properties . What does matter morally is speciesspecific flourishing . We do not pity the cat who cannot philosophize with us because the cat isn ' t the kind of being that can do that . The pig isn ' t the kind of being that can philosophize with us either . However , as the narrator rightly points out , there are human beings that have the mental capacities of a pig , but we do not think it right to kill them for food . Yes , but we also recognize what a shame it is that this human being has the mental capacities of a pig . This human being has a disability . The pig has no such disability . It ' s as it is and expresses the capacities as pigs do . This is a principled reason to separate out disabled human beings from the moral dimension of mere pigs . So even though it would be speciesist to appeal to mere biological differences in species , it is not speciesist to appeal to speciesspecific flourishing to draw that distinction . Therefore , the narrator has failed to persuade because there is , actually , a principled way to differentiate the disabled human being from the healthy pig in moral terms . This is why we can ascribe to disabled human beings right to life respect but we don ' t have to ascribe to mere pigs . edit typo
