People - Ancient Greece: Proclus Born Proclus Lycaeus (8 February 412 – 17 April 485
AD), he was a Greek Neoplatonist philosopher.
Proclus in Harpers Dictionary of Classical Antiquities (1898)
（Πρόκλος). The most important representative of the later Neo-Platonic School, born A.D. 412 at Byzantium. He received his first instruction at Xanthus, in Lycia, and betook himself to Alexandria to complete his education. There he attached himself chiefly to Heron, the mathematician, and to the Aristotelian Olympiodorus. Before the age of twenty, he removed to Athens to attend the lectures of the most celebrated Platonists of the time, Syrianus and Plutarchus. On the death of the latter he became head of the Platonic School until his own death in 485. His disciples were very numerous; and his learning and zeal for the education of the young, combined with his beneficence, his virtuous and strictly ascetic life, and his steadfastness in the faith of his fathers, gained him the enthusiastic devotion of his followers. We possess an account of his life, full of admiration for his character, by his pupil and successor, Marinus. The efforts of Proclus were directed to the support of paganism in its struggle with the now victorious Christianity, by reducing to a system all the philosophic and religious traditions of antiquity. His literary activity was very great, and extended over almost every department of knowledge; but Platonic philosophy was the centre of the whole. His philosophical works, now extant, are a commentary on a few dialogues of Plato (mainly on the Timaeus), also his chief work on the theology of Plato, as well as a summary of the theology of Plotinus, with writings treating several branches of philosophy from his own point of view. Some of his minor works have reached us only in a Latin translation. As specimens of his mathematical and astronomical works, we have a commentary on the first book of Euclid, a sketch of the astronomical teaching of Hipparchus, Ptolemy, and others, a slight treatise on the heavens, etc. One of his grammatical writings survives in his commentary on Hesiod's Works and Days. Lastly, we have two epigrams by him and six hymns. It is doubtful whether the Grammatical Chrestomathy, extracts from which, preserved by Photius, are the only source of our knowledge of the Greek cyclic poets, was really written by him, and not rather by a grammarian of the same name in the second century A.D. There is no complete edition of the works of Proclus. A partial edition is that of Cousin, 6 vols. (Paris, 1820). See Zeller, Philos. der Griechen, iii. 2, in the third edition.
Proclus in Wikipedia
Proclus Lycaeus (8 February 412 – 17 April 485 AD), called "The Successor" or "Diadochos" (Greek Πρόκλος ὁ Διάδοχος Próklos ho Diádokhos), was a Greek Neoplatonist philosopher, one of the last major Classical philosophers (see Damascius). He set forth one of the most elaborate and fully developed systems of Neoplatonism. He stands near the end of the classical development of philosophy, and was very influential on Western medieval philosophy (Greek and Latin) as well as Islamic thought.
"Wherever there is number, there is beauty."
Proclus was born Feb. 8, 412 AD (his birth date is deduced from a horoscope cast by a disciple, Marinus) in Constantinople to a family of high social status in Lycia (his father Patricius was a high legal official, very important in the Byzantine Empire's court system) 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 Constantinopole 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). Eventually, this gifted student became dissatisfied with the level of philosophical instruction available in Alexandria, and went to Athens, the preeminent philosophical center of the day, in 431 to study at the Neoplatonic successor of the famous Academy founded 800 years (in 387 BC) before by Plato; there he was taught by Plutarch of Athens, Syrianus, and Asclepigenia; he succeeded Syrianus as head of the Academy, 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 voluntary one year exile, which was designed to lessen the pressure put on him by his political-philosophical activity, little appreciated by the Christian rulers; he spent the exile travelling and being initiated into various mystery cults as befitted his universalist approach to religion, trying to become "a priest of the entire universe". His house has been discovered recently in Athens, under the pavement, south of Acropolis, opposite the theater of Dionysus. He had a great devotion to the Goddess Athena, whom he believed guided him at key moments in his life. Marinus reports that when Christians removed the statue of the Goddess from the Parthenon, a beautiful woman appeared to Proclus in a dream and announced that the "Athenian Lady" wished to stay at his home. Proclus died aged ~73, and was buried near Mount Lycabettus in a tomb.
The majority of Proclus' works are commentaries on dialogues of Plato (Alcibiades, Cratylus, Parmenides, Republic, Timaeus). In these commentaries he presents his own philosophical system as a faithful interpretation of Plato, and in this he did not differ from other Neoplatonists, as he considered the Platonic texts to be divinely inspired (ho theios Platon -- The divine Plato, inspired by God) and therefore that they spoke often of things under a veil, hiding the truth from the philosophically uninitiate. Proclus was however a close reader of Plato, and quite often makes very astute points about his Platonic sources. A number of his Platonic commentaries are lost.
Proclus also wrote an influential commentary on the first book of Euclid's Elements of Geometry. This commentary is one of the most valuable sources we have for the history of ancient mathematics, and its Platonic account of the status of mathematical objects was influential. In this work, Proclus also listed the first mathematicians associated with Plato: a mature set of mathematicians (Leodamas of Thasos, Archytas of Taras, and Theaetetus), a second set of younger mathematicians (Neoclides, Eudoxus of Cnidus), and a third yet younger set (Amyntas, Menaechmus and his brother Dinostratus, Theudius of Magnesia, Hermotimus of Colophon and Philip of Opus). Some of these mathematicians were influential in arranging the Elements, that Euclid later published.
In addition to his commentaries, Proclus wrote two major systematic works. The Elements of Theology, which consists of 211 propositions, each followed by a proof, beginning from the existence of the One (the first principle of all things) and ending with the descent of individual souls into the material world. The Platonic Theology is a systematisation of material from Platonic dialogues, showing from them the characteristics of the divine orders, the part of the universe which is closest to the One.
We also have three essays, extant only in Latin translation: Ten doubts concerning providence; On providence and fate; On the existence of evils.
He also wrote a number of minor works, which are listed in the bibliography below.
Proclus' system, like that of the other Neoplatonists, is a combination of Platonic, Aristotelian, and Stoic elements. In its broad outlines, Proclus' system agrees with that of Plotinus. However, following Iamblichus, Plutarch of Athens (not to be confused with Plutarch of Chaeronea), and his master Syrianus, Proclus presents a much more elaborate universe than Plotinus, subdividing the elements of Plotinus' system into their logically distinct parts, and positing these parts as individual things. This multiplication of entities is balanced by the monism which is common to all Neoplatonists. What this means is that, on the one hand the universe is composed of hierarchically distinct things, but on the other all things are part of a single continuous emanation of power from the One. From this latter perspective, the many distinctions to be found in the universe are a result of the divided perspective of the human soul, which needs to make distinctions in its own thought in order to understand unified realities. The idealist tendency is taken further in John Scotus Eriugena
There is a double motivation found in Neoplatonic systems. The first is a need to account for the origin and character of all things in the universe. The second is a need to account for how we can know this origin and character of things. These two aims are related: they begin from the assumption that we can know reality, and then ask the question of what reality must be like, in its origin and unfolding, so that we can know it. An important element in the Neoplatonic answer to these questions is its reaction to Scepticism. In response to the sceptical position that we only know the appearances presented by our senses, and not the world as it is, Plotinus placed the object of knowledge inside the soul itself, and accounted for this interior truth through the soul's kinship with its own productive principles.
The first principle in Neoplatonism is the One (Greek: to Hen). It is the principle which produces all Being. For this reason, the Neoplatonists thought that the One could not itself be a being. If it were a being, it would have a particular nature, and so could not be universally productive of all being. Because it is beyond being (epekeina tes ousias is a phrase from Plato's Republic 509b), it is also beyond thought, because thinking requires the determinations which belong to being: the division between subject and object, and the distinction of one thing from another. For this reason, even the name The One isn't a positive name, but rather the most non-multiple name we can think of, a name derived from our own inadequate conception of the simplicity of the first principle. The One causes all things by conferring unity, in the form of individuality, on them, and in Neoplatonism existence, unity, and form tend to become equivalent. The One causes things to exist by donating unity, and the particular manner in which a thing is one is its form (a dog and a house are one in different manners, for example). As the One confers individuality it is in reality the principle of plurality. Because the One makes things exist by giving them the unity which makes them what they are as distinct and separate beings, the Neoplatonists thought of it also as the source of the good of everything. So the other name for the One is the Good. The first principle isn't double, however. Instead, all things have a double relation to it, as coming from it (One) and then being oriented back towards it to receive their perfection or completion (Good).
The particular characteristic of Proclus' system is his insertion of a level of individual ones, called henads between the One itself and the divine Intellect, which is the second principle. The henads are beyond being, like the One itself, but they stand at the head of chains of causation (seirai) and in some manner give to these chains their particular character. They are also identified with the traditional 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. The henads serve both to protect the One itself from any hint of multiplicity, and to draw up the rest of the universe towards the One, by being a connecting, intermediate stage between absolute unity and determinate multiplicity.
In terms of his sources, the One is like a combination of the Platonic Form of the Good, because it confers being and intelligibility on all things, and Aristotle's Unmoved Mover, which is the final cause of all things.
Coming between the One and the henads (some scholars think after the henads) are the two principles of First Limit and First Infinity, which are the principles of the fertile production (Infinity or Unlimited, apeiron) and the controlled nature of the production (Limit, peras) of all things.
The principle which is produced below the level of the One and the Henads is the divine Intellect (Nous). The One cannot have a determinate nature if it is to be the source of all determinate natures, so what it produces is the totality of all determinate natures, or Being. By determination is meant existence within boundaries, a being this and not that. The most important determinate natures are the Greatest Kinds from Plato's Sophist (Being, Same, Other, Rest, Motion) and Aristotle's ten categories (Quantity, Quality, etc.). In other words, the One produces what Plato called the Forms, and the Forms are understood to be the first determinations into which all things fall. The One produces the Forms through the activity of thinking. The One itself does not think, but instead produces a divine mind, Intellect, whose thoughts are themselves the Forms. Intellect is both Thinking and Being. It is a mind which has its own contents as its object. All things relate to the first principle as both One and Good. As Being, Intellect is the product of the One. But it also seeks to return to its cause, and so in Thinking it attempts to grasp the One as its Good. But because the simplicity of the One/Good does not allow Intellect to grasp it, what Intellect does is generate a succession of perspectives around its simple source. Each of these perspectives is itself a Form, and is how Intellect generates for itself its own content.
Plotinus speaks about the generation of Intellect from the One, and Intellect's attempt to return to the One in a thinking which is also a desiring. Proclus systematises this production through a threefold movement of remaining, procession, and return (mone, proodos, epistrophe). Intellect remains in the One, which means that it has the One as its origin. It proceeds from the One, which means that it comes to be as a separate entity. But it returns to the One, which means that it doesn't cut itself off from its source, but receives the good which is its identity from the One. This threefold motion is used by Proclus to structure all levels of his system below the One and above material reality, so that all things except those mentioned remain, proceed, and return.
Proclus also gives a much more elaborate account of Intellect than does Plotinus. In Plotinus we find the distinction between Being and Thinking in Intellect. Proclus, in keeping with his triadic structure of remaining, procession, and return, distinguishes three moments in Intellect: Intelligible, Intelligible-Intellectual, and Intellectual. They correspond to the object of thought, the power of the object to be grasped by the subject, and the thinking subject. These three divisions are elaborated further, so that the intelligible moment consists of three triads (Being, Eternity, and the Living Being or Paradigm from Plato's Timaeus). The intelligible-intellectual moment also consists of three triads, and the intellectual moment is a hebdomad (seven elements), among which is numbered the Demiurge from Plato's Timaeus and also the monad of Time (which is before temporal things). In this elaboration of Intellect as a whole, Proclus is attempting to give a hierarchical ordering to the various metaphysical elements and principles that other philosophers have discussed, by containing them within a single triadic logic of unfolding.
Proclus' universe unfolds according to the smallest steps possible, from unity to multiplicity. With Intellect emerges the multiplicity which allows one being to be different from another being. But as a divine mind, Intellect has a complete grasp of all its moments in one act of thought. For this reason, Intellect is outside of Time.
Intellect as the second principle also gives rise to individual intellects, which hold various places within Proclus' cosmos.
In terms of his sources, Intellect is like taking the Platonic Forms and placing them in the self-thinking thought which is Aristotle's Unmoved Mover.
Soul (Psuche) is produced by Intellect, and so is the third principle in the Neoplatonic system. It is a mind, like Intellect, but it does not grasp all of its own content as one. Therefore with Soul, Time comes to be, as a measure of Soul's movement from one object of thought to another. Intellect tries to grasp the One, and ends up producing its own ideas as its content. Soul attempts to grasp Intellect in its return, and ends up producing its own secondary unfoldings of the Forms in Intellect. Soul, in turn, produces Body, the material world.
In his commentary on Plato's Timaeus Proclus explains the role the Soul as a principle has in mediating the Forms in Intellect to the body of the material world as a whole. The Soul is constructed through certain proportions, described mathematically in the Timaeus, which allow it to make Body as a divided image of its own arithmetical and geometrical ideas.
Individual souls have the same overall structure as the principle of Soul, but they are weaker. They have a tendency to be fascinated with the material world, and be overpowered by it. It is at this point that individual souls are united with a material body (i.e. when they are born). Once in the body, our passions have a tendency to overwhelm our reason. 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 this 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.
For Proclus philosophy is important, because it is one of the primary ways to rescue the soul from a fascination with the body, and restore it to its station. However, beyond its own station, the soul has Intellect as its goal, and ultimately has unification with the One as it goal. So higher than philosophy is the non-discursive reason of Intellect, and the pre-intellectual unity of the One. Philosophy is therefore a means of its own overcoming, in that it points the soul beyond itself.
Proclus' works had a great influence on the history of western philosophy. The extent of this influence, however, is obscured by the channels through which it was exercised. An important source of Procline ideas was through the Pseudo-Dionysius. This late 5th or early 6th century Christian Greek author wrote under the pseudonym Dionysius the Areopagite, the figure converted by St. Paul in Athens. Because of this fiction, his writings were taken to have almost apostolic authority. He is an original Christian writer, and in his works can be found a great number of Proclus' metaphysical principles.
Another important source for the influence of Proclus on the Middle Ages is Boethius' Consolation of Philosophy, which has a number of Proclus principles and motifs. The central poem of Book III is a summary of Proclus' Commentary on the Timaeus, and Book V contains the important principle of Proclus that things are known not according to their own nature, but according to the character of the knowing subject.
A summary of Proclus' Elements of Theology circulated under the name Liber de Causis (the Book of Causes). This book is of uncertain origin, but circulated in the Arabic world as a work of Aristotle, and was translated into Latin as such. It had great authority because of its supposed Aristotelian origin, and it was only when Proclus' Elements were translated into Latin that Thomas Aquinas realised its true origin.
Proclus' works also exercised an influence during the Renaissance through figures such as George Gemistios Plethon and Marsilio Ficino. Before the contemporary period, the most significant scholar of Proclus in the English speaking world was Thomas Taylor, who produced English translations of most of his works, with commentaries.
His work inspired the New England Transcendentalists, including Ralph Waldo Emerson, who declared in 1843 that, in reading Proclus, "I am filled with hilarity & spring, my heart dances, my sight is quickened, I behold shining relations between all beings, and am impelled to write and almost to sing."
Modern scholarship on Proclus essentially begins with E.R. Dodd's edition of the Elements of Theology in 1933. Since then he has attracted considerable attention, especially in the French-speaking world. Procline scholarship, however, still (2006) falls far short of the attention paid to Plotinus.
The following epigram is engraved on the tomb which houses Proclus and his master Syrianus:
"I am Proclus,
Lycian whom Syrianus brought up to teach his doctrine after him.
This tomb reunites both our bodies.
May an identical sojourn be reserved to our both souls!"
The crater Proclus on the Moon is named after him.
