More particularly we would shortly deal with the chief representatives of this philosophy. Scholastic philosophy is considered to begin with John Scotus Erigena who flourished about the year 860, and who must not be confused with the Duns Scotus of a later date. We do not quite know whether he belonged to Ireland or to Scotland, for Scotus points to Scotland, and Erigena to Ireland. With him true philosophy first begins, and his philosophy in the main coincides with the idealism of the Neo-Platonists. Here and there stray works of Aristotle were likewise known, even to John Scotus, but the knowledge of Greek was very limited and rare. He shows some knowledge of the Greek and Hebrew tongues, and even of Arabic as well; but we do not know how he attained to this. He also translated from Greek to Latin writings of Dionysius the Areopagite, a later Greek philosopher of the Alexandrian school, who more especially followed Proclus: namely, _De cœlesti hierarchia_, and others which Brucker calls (Hist. crit. phil. T. III. p. 521), _nugæ et deliria Platonica_. Michael Balbus, Emperor of Constantinople, had in the year 824 made a present of these works to the Emperor Louis the Pious; Charles the Bald caused them to be translated by Scotus, who long resided at his court. In this way something of the Alexandrian philosophy became known in the West. The Pope quarrelled with Charles, and complained to him of the translator, against whom he made the reproach that “he should have first sent the book to him in conformity with the general usage, and asked his approval.” John Scotus afterwards lived in England as head of a school at Oxford, which had been founded by King Alfred.[16]
