Aurelius Augustinus [more commonly "St. Augustine of Hippo," often simply "Augustine"] (354-430 C.E.): rhetor, Christian Neoplatonist, North African Bishop, Doctor of the Roman Catholic Church. One of the decisive developments in the western philosophical tradition was the eventually widespread merging of the Greek philosophical tradition and the Judeo-Christian religious and scriptural traditions. Augustine is one of the main figures through and by whom this merging was accomplished. He is, as well, one of the towering figures of medieval philosophy whose authority and thought came to exert a pervasive and enduring influence well into the modern period (e.g. Descartes and especially Malebranche), and even up to the present day, especially among those sympathetic to the religious tradition which he helped to shape (e.g. Plantinga 1992; Adams 1999).
But even for those who do not share this sympathy, there is much in Augustine’s thought that is worthy of serious philosophical attention. Augustine is not only one of the major sources whereby classical philosophy in general and Neoplatonism in particular enter into the mainstream of early and subsequent medieval philosophy, but there are significant contributions of his own that emerge from his modification of that Greco-Roman inheritance, e.g., his subtle accounts of belief and authority, his account of knowledge and illumination, his emphasis upon the importance and centrality of the will, and his focus upon a new way of conceptualizing the phenomena of human history, just to cite a few of the more conspicuous examples.
