Marsilius of Padua 1275 – 1342

Marsilius of Padua was an Italian political philosopher and physician, one of the most original thinkers of the late Middle Ages. His Defensor Pacis, completed in 1324, constructed a sustained argument that the legislator is the people or the prevailing part thereof, and that the temporal authority of the priesthood is a usurpation that is the principal cause of civil discord. The work led to his condemnation by Pope John XXII and his flight to the court of the Holy Roman Emperor Louis IV. His thought anticipated themes of conciliarism, popular sovereignty, and the separation of church and state.
