Neoplatonism

Neoplatonism, the last school of Greek philosophy, given its definitive shape in the 3rd century ce by the one great philosophical and religious genius of the school, Plotinus. The ancient philosophers who are generally classified as Neoplatonists called themselves simple “Platonists,” as did the philosophers of the Renaissance and the 17th century whose ideas derive from ancient Neoplatonism.
