Abstract
Based on the analysis of the short treatise De divinatione daemonum and some
others references in Augustinian texts, this article aims to retrace Augustine of
Hyppo’s position about the nature of demons and their capacity to foretell future
events. In particular, the research will explore some epistemological topics as the
role of imagination and his phantasmata in the cognitive processes, the semiotic
nature of demonic foreknowledge, the difference between angelic, divine, demonic
and human knowledge. Finally, we’ll draw a summary map of the historical transformations
of the demonic cognition’s theme, from time to time auctoritas, source
and philosophical argument.
