Suppose I commit a crime, but then, perhaps of the untoward rush of blood or adrenalin, retain no memory of the time in question. Then it seems to follow from Locke's theory that I am not the person who committed the crime. I am the same human being, but not the same person. It seems that the one human being is inhabited by multiple successive personalities, as memories come and go.
