a welcome addition to the increasing number of commentaries on individual treatises of Plotinus ... The translation on facing pages is accurate and fluid, and F. helpfully breaks it down into small paragraphs that represent more precisely the subtle shifts in Plotinus' presentation. F.'s is a sound work of scholarship that all Plotinian scholars will profitably consult. This is a well-written monograph on an important topic.

John Bussanich, University of New Mexico, The Classical Review, Vol. XLVI, Vol. 2, '96

This is not only one of the few English commentaries on any single treatise of Plotinus, but it is an informed and informative translation.

Religious Studies Review, vol.23, no.1, January 1997

The translation reads well and ... the commentary is generally excellent.
