Book excerpt: “Neoplatonism, a development of Plato’s metaphysical and religious teaching, whose best-known representatives were Plotinus, Porphyry, Iamblichus and Proclus, was the dominant philosophical school of the later Roman Empire and has been a major influence on European and Near Eastern thought and culture ever since. Yet, though Plotinus has gained fame as a mystic and Porphyry as a formidable opponent of the early Church, the school’s philosophy has been little studied in modern times, largely because of the difficulty of the Neoplatonists’ writings and the lack of a good summary exposition. This defect Dr Wallis seeks to remedy in this, the first full-length study of the school by a single author to appear for over half a century.Dr Wallis’ aim has been to assist readers of the Neoplatonists’ works by an analysis of their leading ideas, based on the most recent scholarship and explaining clearly both what they said and why they said it. Particular attention is given to doctrinal disagreements within the school, and special sections deal with the Neoplatonists’ treatment of Platonic and Aristotelian texts, their attitude to Christianity and their later influence. It is shown how from one point of view Neoplatonism marks a synthesis of Classical Greek thought, whereas from another it applies that synthesis to problems of religious experience and man’s inner life which had been relatively little discussed by its predecessors. It is this application of reason to inner experience, the author suggests, that gives Neoplatonism a continuing importance and special relevance to our own day.”- Publisher
