The Philosophy of Gemistos Plethon

George Gemistos Plethon (c. 1360-1454) was a remarkable and influential thinker, active at the time of transition between the Byzantine Middle Ages and the Italian Renaissance. His works cover literary, historical, scientific, but most notably philosophical issues. Plethon is arguably the most important of the Byzantine Platonists and the earliest representative of Platonism in the Renaissance, the movement which generally exercised a huge influence on the development of early modern thought. Thus his treatise on the differences between Plato and Aristotle triggered the Plato-Aristotle controversy of the 15th century, and his ideas impacted on Italian Renaissance thinkers such as Ficino.

They contain remarkable Platonic ideas, adjusted to the contemporary late Byzantine situation. In the second, most extensive, part of the book the Platonism of Plethon is presented in a systematic way. It is identical with the so-called philosophia perennis, that is, the rational view of the world common to various places and ages. Throughout Plethons writings, it is remarkably coherent in its framework, possesses quite original features, and displays the influence of ancient Middle and Neo-Platonic discussions. Plethon thus turns out to be not just a commentator on an ancient tradition, but an original Platonic thinker in his own right. In the third part the notorious question of the paganism of Gemistos is reconsidered. He is usually taken for a Platonizing polytheist who gathered around himself a kind of heterodox circle. The whole issue is examined in depth again and all the major evidence discussed, with the result that Gemistos seems rat
