The Personal Identity
I view personhood as a public and private self. My public self is defined by my genetic makeup and nothing more. My private self would be define by my memory. If I woke up today with no memory, then I would not be me. What defines me is my pyschological states, which in turn are defined by my memory. The problem is, that my memory is not constant.
Personal identity is always changing, there is never a time in which you are identical to yourself because you will never be yourself for more than a moment.
