  The focus on the subjectivity of persons explains many personalists’ insistence on the difference between the concept of “person” and that of “individual.” Gilson wrote that “every human person is first an individual, but he is much more than an individual, since one only speaks of a person, as of a personage, when the individual substance under consideration possesses in his own right a certain dignity.” The major distinction is that an individual represents a single unit in a homogenous set, interchangeable with any other member of the set, whereas a person is characterized by his uniqueness and irreplaceability.
