Georgius Gemistus Pletho
The Byzantine Platonist whose lectures at the Council of Florence inspired the Medici to found the Florentine Academy and relaunch Plato in the West
Pletho was the most important Byzantine philosopher of the fifteenth century and the catalyst for the Renaissance revival of Plato. Based in Mistra (the Byzantine capital of the Peloponnese), he served as a judge and counselor and wrote extensively on Platonist philosophy, political reform, and the superiority of Plato over Aristotle. In 1438–39 he attended the Council of Florence (called to reunite the Eastern and Western churches) as part of the Byzantine delegation, and his lectures on Plato so impressed Cosimo de' Medici that Cosimo founded the Florentine Academy and commissioned Marsilio Ficino to translate Plato into Latin. Pletho's most controversial work, the "Laws" (Nomoi), modelled on Plato's dialogue of the same name, proposed a reformed Hellenistic pagan theology to replace Christianity — it was burned after his death by the Patriarch Gennadios Scholarios. His "De Differentiis" (On the Differences between Plato and Aristotle) provoked the great fifteenth-century controversy over the relative merits of the two ancient masters. Sigismondo Pandolfo Malatesta had Pletho's remains transferred from Mistra to the Tempio Malatestiano in Rimini — one of the strangest acts of Renaissance intellectual devotion.

Pletho is the most thoroughgoing Platonist of the late Byzantine period — he argued for the decisive superiority of Plato over Aristotle in metaphysics, theology, and ethics, and his De Differentiis launched the fifteenth-century Plato-Aristotle controversy that shaped Renaissance philosophy.
"Plato alone among the Greeks attained to the true theology — the doctrine of the One beyond being and the eternal Forms as the source of all things." (De Differentiis)
Pletho's Platonism is Neoplatonic: the hierarchy of being from the One through Intellect and Soul to Matter, the doctrine of emanation and return, and the identification of the Forms with divine thoughts. He drew on Plotinus, Proclus, and the Chaldean Oracles.
"The One produces all things from itself, not by deliberation but by the overflowing of its own goodness, and all things return to the One as their source." (Laws, fragment)
Pletho was nominally Orthodox and attended the Council of Florence as part of the Byzantine delegation, but his private philosophy (the Laws) was pagan-Platonist. His relation to Orthodoxy is one of cultural context and public conformity rather than conviction.
"Pletho spoke as a Christian at the Council, but his secret Laws revealed a soul that belonged to Plato and Zoroaster rather than to Christ." (Gennadios Scholarios, in his condemnation of the Laws)
Pletho treated Zoroaster as a source of prisca theologia, alongside Plato, and incorporated Zoroastrian-style dualism into his cosmological scheme — the "Summary of the Doctrines of Zoroaster and Plato" is a deliberate syncretism.
"Zoroaster, the most ancient of the theologians, first taught the doctrine of the Good and the necessary structure of being that Plato later refined." (Summary of the Doctrines of Zoroaster and Plato)
Pletho believed in a prisca theologia — an ancient wisdom shared by Zoroaster, the Chaldean Oracles, Pythagoras, and Plato — that represented the true theology humanity had progressively corrupted. This makes him a forerunner of the perennial-philosophy tradition.
"The greatest of the ancient sages — Zoroaster, Pythagoras, Plato — all taught the same fundamental truths about God and the order of being." (De Differentiis)
Internal Tensions
Pletho's private paganism — the Laws' proposal to replace Christianity with a reformed Hellenistic theology — was his most radical and most controversial position. Gennadios Scholarios, who as Patriarch of Constantinople after 1453 had Pletho's Laws burned, called it an attempt to "restore the idolatry of the Greeks." Modern scholars debate whether Pletho was sincerely pagan or using the Platonic framework as a philosophical heuristic. His political-reform writings for the Byzantine emperor were pragmatic and had nothing to do with paganism. The irony of his legacy is that his Platonism, transmitted through Ficino and the Florentine Academy, became the vehicle of a Christian Platonist synthesis — precisely the opposite of what Pletho intended.
I. Time
"Both" — the eternal divine order and the temporal procession of the created cosmos. Cyclical: Pletho's cosmology, following Plato's Timaeus and the Neoplatonic tradition, assumes a cosmic cycle of emanation and return. Deterministic: the Laws' doctrine of fate (De Fato) argues that all things follow necessarily from the divine order.
Attributes
II. Space
Emergent from the divine order; non-local because the Forms (divine thoughts) are not located in any spatial region but structure all of space.
Attributes
III. Matter
Emergent — the lowest level of the Neoplatonic hierarchy. The created material world participates in the Forms but is not itself fully real.
Attributes
IV. Observer
The divine Mind as the ultimate observer — the One whose thought produces and sustains all being. The human soul participates in divine thought through philosophical contemplation. Cosmic-ordering metaphysical agency: the divine hierarchy is an impersonal (or supra-personal) rational order rather than a personal God in the Christian sense.
Attributes
V. Energy
The emanative energy flowing from the One through the hierarchy of being; reversible through the soul's contemplative return to its source.
Attributes
VI. Information
The Forms as eternal informational content; conserved at both cosmic and personal scales through the immortality of the rational soul and the eternity of the divine ideas.
