Although Neoplatonism has long been studied, until recently many had dismissed this complex system of ideas as more mystical than philosophical. Recent research, however, has provided a new perspective on this highly influential school of thought, which flourished in the pagan world of Greece and Rome up through late antiquity. Pauliina Remes`s lucid, comprehensive, and up-to-date introduction reassesses Neoplatonism`s philosophical credentials, from its founding by Plotinus (204-70, C.E.) through the closure of Plato`s Academy in 529. Using an accessible, thematic approach, she explores the ideas of leading Neoplatonists such as Porphyry, Iamblichus, Proclus, Simplicius, and Damascius, as well as less well-known thinkers. She situates their ideas alongside classical Platonism, Stoicism, and the neo-Pythagoreans as well as other intellectual movements of the time, including Gnosticism, Judaism, and Christianity. She also considers Neoplatonism`s enduring legacy in the history of philosophical thought, providing a gateway to Neoplatonism for contemporary readers.
