ABSTRACT
Plotinus is something of an exception in so far as his published work is only in the form of treatises on particular philosophical problems even though the issues o en begin with or closely involve philosophical texts, particularly of course Plato. His seminars too were based on the reading of a philosophical text, but this simply formed the basis of further enquiry and is to be clearly distinguished from the formal exposition of a continuous text, which came to be the general practice.
