 Maritain’s moral philosophy is clearly related to his political philosophy and his philosophy of law. The personalist position that he defended had antecedents in the nineteenth century, but it was perhaps the first to be part of an account of a new model of civilization (De Tavernier 2009). In one of his earliest political works, Maritain described his view as “integral Christian Humanism”—‘integral’, because it considers the human being, an entity that has both material and spiritual dimensions, as a unified whole and because it sees human beings in society as participants in a common good. The object of Maritain’s political philosophy was to outline the conditions necessary to making the individual fully human. His integral humanism, then, seeks to bring the different dimensions of the human person together, without ignoring or diminishing the value of either, and it has been regarded by some as superior to Charles Taylor’s “exclusive humanism” (Klassen 2011) or, at least, as a completion of it (Doyle 2009). While one’s private good as an individual is subordinate to the (temporal) common good of the community, as a person with a supernatural end, one’s ‘spiritual good’ is superior to society—and this is something that Maritain believed all political communities should recognize.
