Robert Wisnovsky's Avicenna's Metaphysics in Context is arguably one of the most important works to come out on Avicenna to date. Wisnovsky has a superb mastery of the philological, historical, and philosophical tools necessary for tackling some of the most central and deepest issues in Avicenna's philosophy. His study is history of ideas done at its best. The work is must reading for anyone studying Avicenna today and likewise will be of interest to those with broader interests, whether in Arabic philosophy and intellectual history, Hellenistic and Neoplatonic studies, medieval Latin philosophy, or the history of philosophy in general.- Jon McGinnis, University of Missouri–St Louis (Journal of the American Oriental Society) Wisnovsky's effort, then, is a resounding success. His study will provide specialists with years' worth of materials to mine and digest, while newcomers are treated to a challenging yet thoroughly engaging introduction to the central metaphysical issues being discussed in late ancient philosophy and the first bloom of Arabic thought. Wisnovsky's book represents the state of the art; it comes highly recommended to anyone interested in the interface between ancient and medieval thought.- Taneli Kukkonen, University of Victoria (Journal of the History of Philosophy) Wisnovsky's approach epitomizes what I see as the three most fruitful avenues for the study of the first few centuries of Arabic philosophy: taking late-antique thought (especially the commentators) into account and being attentive to details of the Arabic translations of philosophical works rather than imagining Avicenna and others as engaging directly with Greek sources. Wisnovsky's outstanding book should serve as a model for future research on Avicenna, and on the formative period of Arabic philosophy in general.- Peter Adamson, King's College London (The Classical Review)
