In the year 1328 Ockham and certain leading members of the Franciscan order became convinced that the pope of the day, Pope John XXII, was a heretic and therefore no pope. From then until his death in 1347 Ockham wrote nothing more (or almost nothing) on logic, natural philosophy, or speculative philosophy but produced a large body of books and pamphlets, commonly called his “political” writings, advocating the deposition of John XXII and his successors, Benedict XII and Clement VI. The quarrel with these popes began when John XXII issued several documents attacking doctrines and practices of the Franciscan order on the subject of poverty, doctrines the Franciscans believed to be based on the Bible and the accepted teaching of the Church. To understand Ockham's political writings, therefore, we must first consider Franciscan ideas about poverty.
