A philosophical commentary on a section of the Enneads written by the last great Neoplatonist thinker, Plotinus. The treatise is entitled 'Concerning Well-Being' and was written at a late stage in Plotinus' life when he was suffering from an illness that was shortly to kill him. Its main concern is with the good man and how he should pursue the good life. The treatise is therefore central to our understanding of Plotinus' ethical theory, and the commentary seeks to explicate and elucidate that theory. Plotinus' views on how one should live in order to fulfil oneself as a human being are as relevant now as they were in the third century AD. All Greek and Latin is translated, while short summaries introducing the content of each chapter help to make Plotinus' argument clear even to the non-specialist.

Plotinus was one of the most influential philosophers of the early Christian world, whose life was dedicated to the care of others and whose extensive treatises were recorded and preserved by his pupil and colleague Porphyry. This book provides a guide to reading and understanding Plotinus and covers many of the topics that he contemplated.

A study examining how Plotinus relates language not only to philosophical reasoning, but to noesis - the intuitive and comprehensive act of intellection, and how he relates language to Union with the One, a union beyond speech and beyond noesis.

Vol. 1 is "Roman life and letters." Studies presented to T. J. Haarho ff.
