 The term “Neoplatonism” refers to a philosophical school of thought that first emerged and flourished in the Greco-Roman world of late antiquity, roughly from the time of the Roman Imperial Crisis to the Arab conquest, i.e., the middle of the 3rd to the middle of the 7th century. In consequence of the demise of ancient materialist or corporealist thought such as Epicureanism and Stoicism, Neoplatonism became the dominant philosophical ideology of the period, offering a comprehensive understanding of the universe and the individual human being’s place in it. However, in contrast to labels such as “Stoic”, “Peripatetic” or “Platonic”, the designation “Neoplatonic” is of modern coinage and to some extent a misnomer. Late antique philosophers now counted among “the Neoplatonists” did not think of themselves as engaged in some sort of effort specifically to revive the spirit and the letter of Plato’s dialogues. To be sure, they did call themselves “Platonists” and held Plato’s views, which they understood as a positive system of philosophical doctrine, in higher esteem than the tenets of the pre-Socratics, Aristotle, or any other subsequent thinker. However, and more importantly, their signature project is more accurately described as a grand synthesis of an intellectual heritage that was by then exceedingly rich and profound. In effect, they absorbed, appropriated, and creatively harmonized almost the entire Hellenic tradition of philosophy, religion, and even literature—with the exceptions of Epicureanism, which they roundly rejected, and the thoroughgoing corporealism of the Stoics. The result of this effort was a grandiose and powerfully persuasive system of thought that reflected upon a millennium of intellectual culture and brought the scientific and moral theories of Plato, Aristotle, and the ethics of the Stoics into fruitful dialogue with literature, myth, and religious practice. In virtue of their inherent respect for the writings of many of their predecessors, the Neoplatonists together offered a kind of meta-discourse and reflection on the sum-total of ideas produced over centuries of sustained inquiry into the human condition.
