Suppose the following about persons.
- Persons have sensory experiences from certain vantage points
- Persons’ have psychological states
- Sensory experience and psychological states can vary as a function of vantage point
How does this effect personal identity? To put it briefly, it would mean that for one person to be identical with another, then (given Leibniz Law, strictly enforced) the persons would have to be identical according, at least, to the following variables:
- Sensory experience and psychological state(s)
- Vantage point(s)
