Abstract

LOCKE'S DISCUSSION OF ORGANISMS AND PERSONS IN "ESSAY" II.XXVI HAS LED GEACH AND OTHERS TO ATTRIBUTE THE THESIS OF RELATIVE IDENTITY TO HIM; THAT X IS NEVER IDENTICAL WITH Y "TOUT COURT" BUT ONLY RELATIVE TO SOME SORTAL PROPERTY F: X IS THE SAME F AS Y. I ARGUE THAT THIS ATTRIBUTION RESTS ON A MISUNDERSTANDING OF LOCKE'S POSITION. LOCKE INDEED HOLDS THAT AN OLD TREE MAY BE THE SAME OAK AS THE SEEDLING FROM WHICH IT GREW, WHEREAS THE PARTICLES COMPOSING THE TREE AND THE SEEDLING ARE DIFFERENT MASSES OF MATTER. BUT HE ALSO HOLDS THAT PLANTS AND MASSES OF MATTER ARE DISTINCT ENTITIES TO START WITH, EVEN IF THEY OCCUPY THE SAME PLACE AT THE SAME TIME. AND SIMILARLY WITH PERSONS AND MEN. THE RESULT IS A COPIOUS ONTOLOGY, BUT THERE IS NO REASON TO THINK THAT LOCKE WOULD OR SHOULD HAVE BEEN BOTHERED BY THAT
