=William of Ockham=, ‘Auctor nominalium,’ ‘Doctor singularis,’ ‘Doctor invincibilis[1446],’ was born probably towards the end of the thirteenth century. Whether he was a pupil of Duns Scotus is doubtful. He studied at Oxford in the early years of the fourteenth century, and became B.D. there[1447]. After this he was called to Paris, where he incepted as D.D. Here he became acquainted with Marsiglio of Padua, over whom, according to Pope Clement VI, he exercised a powerful influence[1448]. It is probable that he was present at the famous Chapter of Perugia (1322), though he was not (as is usually asserted) Provincial of England[1449]. From the first he took a prominent part in the struggle against the Pope[1450]. He was imprisoned at Avignon about the end of 1327, and a process was instituted against him in the Curia ‘because of many erroneous and heretical opinions which he had written[1451].’ He remained in custody for seventeen weeks, and refused to modify his opinions. It is said that a ‘rich and noble lady,’ in admiring recognition of his staunch defence of ‘Evangelical Poverty,’ gave him 70 florins[1452]. On May 25, 1328, he fled from Avignon with Cesena, the General Minister, and Bonagratia, joined the Emperor in Italy, and was excommunicated[1453]. In Feb., 1330, he accompanied Louis to Bavaria, and lived henceforth for the most part in the Franciscan Convent at Munich[1454]. His literary activity was enormous, as may be seen from the list of his works. He took a direct part in the affairs of state, being present at the Councils of Rense and Frankfurt in 1338[1455]. From this time his writings, hitherto largely theological, became more distinctly political[1456]. In spite of excommunication, he continued to support the Emperor’s cause till Louis’ death in 1347, and even later[1457]. But now few only of the rebel friars were left: Cesena died in 1342, Bonagratia in 1347; and in 1349 Ockham sent back the seal of the Order to the orthodox General Minister, and professed his desire to be reconciled to the Church[1458]. Clement VI authorized the General Minister to absolve Ockham and his associates on their confessing in set form their errors and heresies, and promising to obey the Pope and his successors. Whether Ockham subscribed the papal formula, nothing remains to show. The date of his death is uncertain; it may however be concluded that he died at Munich not before 1349[1459].
