Abstract

This paper studies the transformation of the foundations of ancient skepticism in Augustinian thought; to present the process we start from the crisis that led to the break with Manichaean experience, we distinguished their concern and consideration about the mode and limits of knowledge and analyzed the function of Proteo's mythical image in Contra academicos; this image allows us to weigh the capacity of mythical representation as a buttress of the discursive character of human knowledge. Through this resource, St. Augustine affirms that reason cannot be isolated from other complementary modes of understanding, appropriates the core of the skeptical attitude and broadens the notion of rationality for Christian philosophy.
