The light of the mind

St. Augustine is the bridge that links ancient philosophy and early Christian theology to the thought patterns of the Middle Ages. But the influence of Augustine's philosophy in general and his epistemology in particular extends far beyond medieval philosophy. Such modern philosophers as Descartes and Malebranche carry the stamp of Augustinism upon their philosophies. What is not so well known is that even some of the most original ideas of Berkeley and Kant can be found anticipated in Augustine.
