William of Ockham, On Heretics, Books 1-5 and Against John, Chapters 5-16

A new translation of a work by one of the outstanding thinkers of the later Middle Ages, William Ockham. Ockham's purpose in writing was to advocate for freedom of thought and speech within the Church, to restrain coercion in matters of belief, and to provide a theological framework for deposing a pope.
