Neoplatonism

Neoplatonism , noun

[Neo- + Platonism.]

A pantheistic eclectic school of philosophy, of which Plotinus was the chief (a. d. 205-270), and which sought to reconcile the Platonic and Aristotelian systems with Oriental theosophy. It tended to mysticism and theurgy, and was the last product of Greek philosophy.
