<philosophical school> neplatonism refers specifically to the doctrines of Plotinus (205-270 CE) and his followers in the early centuries CE, and more generally to the tradition of such thought stretching through late antiquity into the Middle Ages and early Renaissance. Neo-Platonism was a revamped Platonism which put greater emphasis on Plato's dualism and idealism, even to the point of a spiritualism which early Christian theologians like Augustine found congenial despite the basic pantheism of Neo-Platonic ideas.
