Aristotle and Neoplatonism in Late Antiquity: Interpretations of the "De Anima" (review)

The label ‘Neoplatonism’, coined in the eighteenth century to indicate a putative and rather ill-defined development within the Platonic tradition, is to this day applied in sundry ways. Presumably, ‘Neoplatonic’ is supposed to be distinguished from ‘Platonic’, but the problem with this is that most of those ancient philosophers called ‘Neoplatonic’ thought of themselves simply as Platonists, that is, as authentic interpreters and continuators of Plato. Nevertheless, there are several important and relatively clear differentiations to be made among those within this tradition. One such refers to those Platonists who attempted to appropriate Aristotle’s philosophy. This was done principally in two ways. For Plotinus, Aristotelian concepts and distinctions were employed to defend Plato against Peripatetic attacks. For Porphyry and the later Platonic commentators on the works of the Aristotelian corpus, Aristotle was co-opted as an authority on the philosophy of the sensible world, leaving the higher, intelligible world to Plato. The commentaries on Aristotle’s De Anima are particularly revealing in this regard. For one would assume that in matters regarding the soul it would be extremely difficult to see Aristotle and Plato as anything other than irreconcilable. Aristotle’s hylomorphism and explicit denial of the immortality of the soul hardly seem to be compatible with that which can be called, even on the most charitable interpretation, genuinely Platonic. In fact, the reconciliation of Aristotelian and Platonic soul doctrines is one of the central tasks late Platonists set for themselves. As Blumenthal notes: “Whatever the historical truth about the relation of Aristotle’s thought to Plato’s may have been, the Neoplatonist regarded it as propaedeutic to Plato’s as well as aiming at the same goal” (25).

H. J. Blumenthal’s long-anticipated monograph explores in minute detail the extant commentaries on Aristotle’s De Anima written by late Platonic or, if one insists, Neoplatonic philosophers. This book builds upon a large body of frequently groundbreaking work by the author on various facets of late Greek philosophy. The main commentaries studied are those of John Philoponus and the unknown authors dubbed ‘Pseudo-Philoponus’ and Pseudo-Simplicius’, though there is also considerable attention paid to Themistius, the last Peripatetic commentator on De Anima and, of course, Alexander of Aphrodisias, whose commentary on De Anima has not survived but whose own immensely influential Peripatetic treatise on the soul does.

This book is divided into two parts: I. Commentaries and Commentators and II. Interpretations of the De Anima. The first part provides the essential background to the second. Anyone approaching the Aristotelian commentators for the first time will find here a most useful guide. Even those who have some familiarity with this material will benefit from the author’s extensive knowledge of detail and judicious examination of some of the difficult issues of dating, authorship, philosophical lineage, and so on.

The second section of the book concentrates on the De Anima commentaries. Here the author, following the order of the text of De Anima, systematically surveys the positions of the commentators on some of the central issues taken up in Aristotle’s work. These include the commentators’ efforts to reconcile Aristotle’s definition of the soul with Platonic assumptions about its nature and Plato’s tripartite division of the soul with Aristotle’s not entirely clear divisions. One of the instructive features of this comparative study of the commentaries is to see frequently how the issues that seize the imagination of modern commentators trouble the ancients not at all and vice versa.

Most readers will be mainly interested in the chapters on the commentaries on the latter part of Book Two and Book Three of De Anima. From Plotinus onward, some of the most original philosophizing in the Platonic tradition focuses on self-consciousness, memory, imagination, and the integrative operation of the rational and arational powers. The last two chapters are filled with material about these issues as well as the...
