What is often termed the modern crisis of the Western self—the problems associated with the proto-Cartesian and proto-Kantian conceptions of the self—has given rise to attempts not only to confront the crisis constructively, but also to trace its origin. In one philosophical reading of the development of the crisis in the Western self, Augustine stands as one of its forefathers. In this reading, Augustine's anthropology is anchored firmly within Platonism and is viewed as a key precursor of the tradition leading to the modern, autonomous self of Descartes and Kant. Such a reading often focuses on Augustine's somewhat idiosyncratic self-analysis in Confessionum libri [Conf.] XIII, and points to his so-called psychological model of the Trinity found in De Trinitate [Trin.]. It is argued that his method of inward movement, which involves the utilization of the structures of individual consciousness as an analogy to the immanent Trinity, in conjunction with his analysis of the individual self in Conf., becomes a basic foundation for the modern private, autonomous self.
