Atticus (fl. c. 175 AD) was an ancient Platonic philosopher who lived in the second century of the Christian era, under the emperor Marcus Aurelius.[1][2] His lifetime fell into the epoch of Middle Platonism, of which he was one of the most notable representatives.
Atticus was vehemently anti-Peripatetic. From the writings of Atticus, which have only been handed down in fragmentary form, it can be seen that he was conservative and wanted to purge what he saw as the original teachings of Plato from the intrusion of elements of Aristotelianism. As an interpreter of Plato, Atticus thought philologically and advocated a literal, not metaphorical, interpretation of the Plato's doctrine of creation. Atticus' position represents a version of Platonism according to which deviation from the literal word of the master means irredeemable heretical opposition. His work was a polemic, possibly originating from his position as the first holder of the Platonic philosophy chair at Athens under Marcus Aurelius. Atticus insisted that Aristotle was an atheist, that he denied the existence of the soul, and that he rejected divine providence. This led him to believe that the world had a beginning in time.
With this rejection of the eternity of the world and also with his understanding of the Demiurge and the theory of forms, as well as his anti-Aristotelian attitude, Atticus represented a decidedly opposed position to views that later became part of the core of the ideas of Neoplatonism in Late Antiquity. He exerted a large degree of influence on later Neoplatonists, most of whom disputed his philosophical ideas, as well as influencing many Christian philosophers, who often saw his ideas as more compatible with theirs.
