The view that persons, divine or human, play the primary role in the structure of the universe.
Personalism exists in a wide variety of forms, and is closely related to idealism (the term personal idealism is often used) or to theism.
What they have in common is that the notion of a person is treated as basic and not to be analyzed in terms of, or seen as emerging out of, other entities.
