fubarobfusco, I share your reservations about DSM. Nonetheless, the egocentric illusion, i.e. I am the centre of the universe other people / sentient beings have only walk-on parts, is an illusion. Insofar as my behaviour reflects my pre-scientific sense that I am in some way special or ontologically privileged, I am deluded. This is true regardless of whether one's ontology allows for the existence of rights or treats them as a useful fiction. The people we commonly label "psychopaths" or "sociopaths" - and DSM now categorises as victims of "antisocial personality disorder" - manifest this syndrome of egocentricity in high degree. So does burger-eating Jane.
