Question:
Answer:
The presence of a spiritual soul determines personhood. Dolphins do not have a spiritual soul, so they are not persons, no matter how intelligent they may be. If personhood were dependent on intelligence alone, then we would have to say that people who are cognitively disabled are not really persons. However, since it is the soul made in the image and likeness of God that determines personhood, cognitive disabilities do not determine a status as a human person.
