John Locke's Treatment Of Personal Identity

Locke’s theory was opposed, objected and scrutinized by many modern philosophers like John Perry and Thomas Reid. Locke was the first one to separate out the specific issue of personal identity from the larger topic of identity in general. Locke's treatment of personal identity might seem counterintuitive to a lot of people, especially his claim that consciousness, and therefore personal identity, are independent of all substances. Notice, however, that the claim is not that consciousness can exist independent of a body or a mind, only that there is no reason to assume that consciousness is tied to any particular body or mind. Still, there is no reason to assume, on this view, that consciousness cannot be transferred from one body or mind …show more content…

In addition to being somewhat counterintuitive, the claim that consciousness is independent of any mind raises some thorny problems. As a really existing thing, consciousness must either be a substance or a quality of a substance. Since Locke admits that consciousness cannot exist on its own, but must be part of some mind or other, it seems likely that consciousness is a property that belongs to minds. It is not clear, though, that a property can simply be transferred from one substance to another. A property belongs to a substance in a very intimate way. To say, then, that consciousness does not belong to any one mind in particular seems to indicate that it is not a property. If it were a substance, though, it would be able to exist independent of any mind at all. Locke does allow that he is not sure whether consciousness can, in fact, be transferred between thinking things, but he dismisses the practical question as irrelevant. However, this practical question might hold part of the answer to the nature of consciousness: whether it is just a property or something more substantial. Locke's theory of personal identity is also on doubt. For instance, imagine that a man commits a crime, but at the time of trial he does not remember committing the crime. Would Locke be forced to say that the man who committed the crime was an entirely different person from the man on trial? Locke would probably respond that so long as the man on trial had some memories connecting his consciousness to the consciousness of his self at that earlier date, he could still be considered the same person, regardless of whether he remembered the specific crime. Consider, though, another example: An old man who cannot remember anything about his youth. Is he a different person from the one who lived his young life? A critic says that this type of consideration into an objection
