Aristotle's Categories in the Early Roman Empire (Oxford, 2015)

This volume studies the origin and evolution of philosophical interest in Aristotle's Categories. After centuries of neglect, the Categories became the focus of philosophical discussion in the first century BCE, and was subsequently adopted as the basic introductory textbook for philosophy in the Aristotelian and Platonic traditions.


Griffin maps out this early exegetical tradition combining philological skills, historical caution and philosophical sensitivity, and succeeds in showing that there was a subtle and sophisticated philosophical controversy among the early exegetes of the Categories… Griffin must be congratulated for exploring the early exegetical tradition of the Categories in such detail and for confirming that exegetical debates in later ancient philosophy are not scholastic developments but philosophically and historically significant. His book will remain a standard work of reference in the field of the exegetical tradition of the Categories. (George Karamanolis in NDPR 2016.03.08)

All in all, this fine work provides an excellent overview of the first generations of exegesis and commentary on the Categories, a period previously—despite the fine work of such figures as Paul Moraux and, more recently, Jonathan Barnes, Riccardo Chiaradonna, and Marwan Rashed—sunk in obscurity. Not all of the obscurity can be lifted, admittedly, by reason of the nature of the evidence, but for his fine effort to do so Michael Griffin has put all of ancient philosophy in his debt. (John Dillon in BMCR 2016.02.12)

[A] major and very welcome contribution to the understanding of post-Hellenistic philosophy. […] This book is a considerable feat of judicious analysis and reconstruction… the questions that Griffin leaves us with are the sort that scholars can get their teeth into. This is a major work which will become an important reference-point in future research on the post-Hellenistic period. (George Boys-Stones in Phronesis 60 [2015] 493-500)

This book offers a clear and compelling presentation of the surviving evidence. It fills a significant lacuna and marks a considerable step forward in scholarship. […] It is a must-read for scholars with an interest in post-Hellenistic philosophy. (Andrea Falcon in Sehepunkt 15 [2015] 7/8)

Olympiodorus on Plato Alcibiades I (Bloomsbury, 2014 & 2016)

This is the first translation of this text into a modern language. Olympiodorus (AD c. 500–570), possibly the last non-Christian teacher of philosophy in Alexandria, delivered these lectures as an introduction to Plato with a biography. They can also serve as an accessible introduction to late Neoplatonism.


Griffin's two volumes are a considerable scholarly achievement. They open up a window into a world in which philosophy had a very different role and self-conception. [...] Griffin's introduction on the virtues and psychic transformation is particularly valuable... It should invite both specialists and general readers to reflect on what we are really doing when we teach philosophy by providing a contrast with our own more modest self-conception.  (Dirk Baltzly in NDPR 2017.02.07)

G. has taken on the thankless task of the translator with commendable enthusiasm, thoroughness and accuracy. [...] G.’s account of [the] theory of a ‘scale of the virtues’… is one of the most philosophically sensitive and lucid treatments of the subject known to this reviewer. (Sebastian Gertz in International Journal of the Platonic Tradition 2017, 71-115, on Lectures 10-28)

Olympiodorus’ Alcibiades commentary... has remained untranslated since the appearance of the critical edition nearly sixty years ago. The work... is thus a step toward filling a definite gap in the scholarship. (Topher Kurfess in BMCR 2015.10.30)

Griffin… is responsible for an elegant translation of the first nine of Olympiodorus’ lectures on the Alcibiades… Apart from dealing expertly with the social and intellectual context of Olympiodorus’ work… Griffin’s introduction also deals extensively with the ancient reception history of the Alcibiades itself. (George Boys-Stones in Phronesis 60 [2015] 493-500, on Lectures 1-9)
