William of Ockham (1288 - 1348) was an English Franciscan friar and scholastic philosopher, from Ockham, a small village in Surrey.
Guillermo he was poor, he died for Black Death. He studied theology at the University of Oxford from 1309 to 1321, but never completed his master's. Because of this, he acquired the byname Venerabilis Inceptor, or Worthy Beginner (although he was also).A pioneer of nominalism, some consider him the father of modern epistemologyt and many scholars have thought that Ockham was summoned before the Papal court of Avignon in 1324 under charges of heresy,
