Gemistus Pletho
At the same council appeared the celebrated Platonist, Gemistus Pletho, the most powerful opponent of the then dominant Aristotelianism, and consequently an antagonist of Scholarius. In church matters, as in philosophy, the two were opposed – Pletho advocated a partial return to Greek paganism in the form of a syncretic union between Christianity and Zoroastrianism; while Scholarius, more cautious, pressed the necessity for ecclesiastical union with Rome on doctrinal grounds, and was instrumental in drawing up a form which from its vagueness and ambiguity might be accepted by both parties. Georgios Scholarius was at a serious disadvantage because, being a layman, he could not directly take part in the discussions of the council.
