Proclus Lycius (; 8 February 412 CE – 17 April 485 CE), called Proclus the Successor (Ancient Greek: Πρόκλος ὁ Διάδοχος, Próklos ho Diádokhos), was a Greek Neoplatonic philosopher, one of the last major classical philosophers of late antiquity. He set forth one of the most elaborate and fully developed systems of Neoplatonism and, through later interpreters and translators, exerted an influence on Byzantine philosophy, early Islamic philosophy, scholastic philosophy, and German idealism, especially G. W. F. Hegel, who called Proclus's Platonic Theology "the true turning point or transition from ancient to modern times, from ancient philosophy to Christianity."
Biography
The primary source for the life of Proclus is the eulogy Proclus, or On Happiness that was written for him upon his death by his successor, Marinus. Marinus's biography set out to prove that Proclus reached the peak of virtue and attained eudaimonia. There are also a few details about the time in which he lived in the similarly structured Life of Isidore written by the philosopher Damascius in the following century. According to Marinus, Proclus was born in 412 AD in Constantinople to a family of high social status from Lycia, and raised in Xanthus. He studied rhetoric, philosophy and mathematics in Alexandria, with the intent of pursuing a judicial position like his father. Before completing his studies, he returned to Constantinople when his rector, his principal instructor (one Leonas), had business there. Proclus became a successful practicing lawyer. However, the experience of the practice of law made Proclus realize that he truly preferred philosophy. He returned to Alexandria, and began determinedly studying the works of Aristotle under Olympiodorus the Elder. He also began studying mathematics during this period as well with a teacher named Heron (no relation to Hero of Alexandria, who was also known as Heron). As a gifted student, he eventually became dissatisfied with the level of philosophical instruction available in Alexandria, and went to Athens, philosophical center of the day, in 431 to study at the Neoplatonic successor of the New Academy, where he was taught by Plutarch of Athens (not to be confused with Plutarch of Chaeronea), Syrianus, and Asclepigenia; he succeeded Syrianus as head of the Academy in 437, and would in turn be succeeded on his death by Marinus of Neapolis. He lived in Athens as a vegetarian bachelor, prosperous and generous to his friends, until the end of his life, except for a one-year exile, to avoid pressure from Christian authorities. Marinus reports that he was writing seven hundred lines each day.
Philosophy
One challenge with determining Proclus' specific doctrines is that the Neoplatonists of his time did not consider themselves innovators; they believed themselves to be the transmitters of the correct interpretations of Plato himself. Although the neoplatonic doctrines are much different from the doctrines in Plato's dialogues, it's often difficult to distinguish between different Neoplatonic thinkers and determine what is original to each one. For Proclus, this is largely only possible with Plotinus, the only other Neoplatonic writer for whom a significant amount of writings survive. Proclus, like Plotinus and many of the other Neoplatonists, agreed on the three hypostases of Neoplatonism: The One (hen), The Intellect (nous) and The Soul (psyche), and wrote a commentary on the Enneads, of which only fragments survive. At other times he criticizes Plotinus' views, such as the prime mover. Unlike Plotinus, Proclus also did not hold that matter was evil, an idea that caused contradictions in the system of Plotinus. It is difficult to determine what, if anything, is different between the doctrines of Proclus and Syrianus: for the latter, only a commentary on Aristotle's Metaphysics survives, and Proclus never criticizes his teacher in any of his preserved writings. The particular characteristic of Proclus's system is his elaboration of a level of individual ones, called henads, between the One which is before being and intelligible divinity. The henads exist "superabundantly", also beyond being, but they stand at the head of chains of causation (seirai) and in some manner give to these chains their particular character. He identifies them with the Greek gods, so one henad might be Apollo and be the cause of all things apollonian, while another might be Helios and be the cause of all sunny things. Each henad participates in every other henad, according to its character. What appears to be multiplicity is not multiplicity at all, because any henad may rightly be considered the center of the polycentric system. According to Proclus, philosophy is the activity which can liberate the soul from a subjection to bodily passions, remind it of its origin in Soul, Intellect, and the One, and prepare it not only to ascend to the higher levels while still in this life, but to avoid falling immediately back into a new body after death. Because the soul's attention, while inhabiting a body, is turned so far away from its origin in the intelligible world, Proclus thinks that we need to make use of bodily reminders of our spiritual origin. In emphasizing the importance of an embodied practice of philosophy, he agrees with the doctrines of theurgy put forward by Iamblichus. Theurgy is possible because the powers of the gods (the henads) extend through their series of causation even down to the material world. And by certain power-laden words, acts, and objects, the soul can be drawn back up the series, so to speak. Proclus himself was a devotee of many of the religions in Athens, considering that the power of the gods could be present in these various approaches.
