Resumen En este artículo se argumenta a favor del modelo no posesivo del Yo. Se presenta la crítica de P. Strawson a este modelo, para elaborar una defensa que descansa en una tesis de posesión cerebral, la cual supone que las experiencias, en cuanto entidades ontológicamente no-suficientes, dependen para su existencia e identidad de la existencia de un cerebro particular.In the present investigation we will present arguments in favor of the no-ownership model of self. We will initially present the criticism (...) that Strawson makes to this model, to present a defense that rests on a thesis of cerebral possession, that assumes that the experiences as non-sufficiency ontological entities depend for their existence and identity on the existence of a particular brain.
