This article, by analysing, annotating en interpreting the most recent research in all relevant departments, provides a fresh and updated overview of the Neoplatonic metaphysics of Pseudo-Dionysius (ca. 500). After providing an introduction to Dionysius’ metaphysics in terms of the contributions of Middle Platonism and Neoplatonism, the article explores his broader philosophical system. A number of traits that are uniquely Dionysic-metaphysical, are eventually isolated: the interpretation of transcendence as bound to immanence; the affirmation of God’s transcendence in the world (that (...) is, a metaphysics of ‘creation as teophany’; following E.D. Perl); the radical transcendence and simultaneous radical immanence of God (that is, God as ‘Beingness’); fundamental restrictions of language and the analogical ‘Naming’ of God; creation as a system of dialectical symbols about God; the analogical participation of the subject in creation; and unification (reditus, the ‘flowing of things back to God’). These traits are utilised to reappraise the metaphysics of Nicholas of Cusa (1401–1464) in a subsequent article. (shrink)
