A human corpse is still a human, but it is not a person. One might say a dead person, but what we mean by that is that they have ceased to be a person. After all, how can a person be a person without life? If there hypothetical aliens, could they be persons? Sure. The Godhead consists of three persons; Father, Son, and Holy Spirit.
I think the best way to describe what a person is is something that has reason and consciousness. Consciousness is hard to define, but a major part of it is self-awareness and being able to distinguish between the "imagined" and the "actual."
A human is simply genetic. I am a human because I am a homo sapient. It is in my DNA. My personhood may somehow be linked, but they are clearly not the same thing.
My best answer.
That is a good definition, as far as it goes. We generally consider persons to be those capable of at least subjective experience (that is, at its most basic, awareness of pleasure and pain) and some level of self-perception. This definition, however, both includes some nonhuman beings and excludes some human beings. It would include other animals such as chimpanzees, dolphins, elephants or wolves; while at the same time, it would exclude humans who are pre-sentient (that is, the majority of human foetuses that are deliberately aborted) or who are in a persistent vegetative state.
