In philosophy, the question is asked seriously, without intention of insulting. A philosopher who misbehaves at a party and is reprimanded by another guest – “Are you a person or an animal?” – could answer, shamelessly: Eh, I really don’t know, philosophers have contemplated that question for hundreds of years.
What then is the philosophical question? It is usually described as the problem of personal identity. What are we, essentially? What constitutes “me”? What holds the self together? When does it arise and when does it disappear?
According to proponents of a psychological view, we (human beings) are persons with certain psychological capacities, such as self-awareness. That psychology holds the self together. If an unusual disease made my body deteriorate, but doctors managed to transplant my mental contents (self-awareness, memories, etc.) into another body, then I would survive in the other body. According to proponents of the rival, animalist view, however, we are animals with a certain biology. An animalist would probably deny that I could survive in a foreign body.
The difference between the two views can be illustrated by their consequences for a bioethical question: Is it permissible to harvest organs from brain-dead bodies to use as transplants? If we are essentially persons with self-awareness, then we cease to exist when the brain dies. Then it should be permissible to harvest organs; it would not violate personal autonomy.
