  Plotinus (204/5 – 270 C.E.), is generally regarded as the founder of Neoplatonism. He is one of the most influential philosophers in antiquity after Plato and Aristotle.  The term ‘Neoplatonism’ is an invention of early 19th century European scholarship and indicates the penchant of historians for dividing ‘periods’ in history.  In this case, the term was intended to indicate that Plotinus initiated a new phase in the development of the Platonic tradition.  What this ‘newness’ amounted to, if anything, is controversial, largely because one’s assessment of it depends upon one’s assessment of what Platonism is.  In fact, Plotinus (like all his successors) regarded himself simply as a Platonist, that is, as an expositor and defender of the philosophical position whose greatest exponent was Plato himself.  Originality was thus not held as a premium by Plotinus.  Nevertheless, Plotinus realized that Plato needed to be interpreted.  In addition, between Plato and himself, Plotinus found roughly 600 years of philosophical writing, much of it reflecting engagement with Plato and the tradition of philosophy he initiated.  Consequently, there were at least two avenues for originality open to Plotinus, even if it was not his intention to say fundamentally new things.  The first was in trying to say what Plato meant on the basis of what he wrote or said or what others reported him to have said.  This was the task of exploring the philosophical position that we happen to call ‘Platonism’.  The second was in defending Plato against those who, Plotinus thought, had misunderstood him and therefore unfairly criticized him.  Plotinus found himself, especially as a teacher, taking up these two avenues. His originality must be sought for by following his path.
