Alvin Plantinga on God and PersonhoodKnowledge of God by Alvin Plantinga and Michael Tooley (Blackwell: May 2, 2008), pp.1-3.
According to classical theistic belief — classical Muslim and Jewish as well as Christian belief — first of all there is God, the chief being of the universe, who has neither beginning nor end. Most important, God is personal. That is, God is the kind of being who is conscious and enjoys some kind of awareness of his surroundings (in God’s case, that would be everything). Second (though not second in importance), a person has loves and hates, wishes and desires; she approves of some things and disapproves of others; she wants things to be a certain way. We might put this by saying that persons have affections. A person, third, is a being who has beliefs and, if fortunate, knowledge. We human beings, for example, believe a host of things… Persons, therefore, have beliefs and affections. Further, a person is a being who has aims and intentions; a person aims to bring it about that things should be a certain way, intends to act so that things will be the way he wants them to be… Finally, persons can often act to fulfill their intentions; they can bring it about that things are a certain way; they can cause things to happen. To be more technical (though not more insightful or more clear), we might say that a person is a being who can actualize states of affairs. Persons can often act on the basis of what they believe in order to bring about states of affairs whose actuality they desire. ¶ So a person is conscious, has affections, beliefs, and intentions, and can act… First, therefore, God is a person. But second, unlike human persons, God is a person without a body. He acts, and acts in the world, as human beings do, but, unlike human beings, not by way of a body. Rather, God acts just by willing: he wills that things be a certain way, and they are that way. (God said “Let there be light”; and there was light.)
