Neoplatonism

Overview

Neoplatonism is a version of Platonic philosophy that emerged in the 3rd century AD against the background of Hellenistic philosophy and religion. The term does not encapsulate a set of distinct ideas based on a form of Platonism as much as a series of Platonic thinkers coming primarily from a certain ancient historical period. Among the common ideas it maintains is monism, the doctrine that all of reality can be derived from a single principle, "the One".

Neoplatonism began with Ammonius Saccas and his student Plotinus (c. AD 205 – 271) and stretched to the sixth century. After Plotinus there were three distinct periods in the history of Neoplatonism: the work of his student Porphyry (third to early fourth century); that of Iamblichus (third to fourth century); and the period in the fifth and sixth centuries, when the academies in Alexandria and Athens flourished.

Neoplatonism had an enduring influence on the subsequent history of Western philosophy and religion. In the Middle Ages, Neoplatonic ideas were studied and discussed by Christian, Jewish, and Muslim thinkers. In the Islamic cultural sphere, Neoplatonic texts were available in Arabic and Persian translations, and notable philosophers such as al-Farabi, Solomon ibn Gabirol (Avicebron), Avicenna (Ibn Sina), and Maimonides incorporated Neoplatonic elements into their own thinking.

Christian philosopher and theologian Thomas Aquinas (1225–1274) had direct access to the works of Proclus, Simplicius of Cilicia, and Pseudo-Dionysius the Areopagite, and he knew about other Neoplatonists, such as Plotinus and Porphyry, through second-hand sources. The German mystic Meister Eckhart (c. 1260 – c. 1328) was also influenced by Neoplatonism, propagating a contemplative way of life which points to the Godhead beyond the nameable God. Neoplatonism also had a strong influence on the perennial philosophy of the Italian Renaissance thinkers Marsilio Ficino and Giovanni Pico della Mirandola, and continues through 19th-century Universalism and modern-day spirituality.

Epicurus added the third, to wit, gravity; for he pronounced that it is necessary that bodies receive their motion from that impression which springs from gravity, otherwise they could not be moved.

c. The triad (_τριάς_) has now become a most important number, seeing that in it the monad has reached reality and perfection. The monad proceeds through the duad, and again brought into unity with this undetermined manifold, it is the triad. Unity and multiplicity are present in the triad in the worst possible way—as an external combination; but however abstractly this is understood, the triad is still a profound…

Hence it follows that they are moved by some intellectual substances. Augustine appears to be of the same opinion when he expresses his belief that all corporeal things are ruled by God through the spirit of life (De Trin. iii, 4). From what has been said, then, it is clear that the heavenly bodies are not living beings in the same sense as plants and animals, and that if they are called so, it can only be…
