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' 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. It is copublished by Acumen Publishing Limited.
