Medieval formal logic

"Medieval Formal Logic treats central topics of medieval logic in a way congenial to the modern reader without compromising historical reliability. The book brings the achievements of medieval logic to a wider philosophical public, and the intended audience includes philosophers working in different areas of philosophy and logic, and not only medievalists. The subjects covered include three central genres of the so-called logica moderna arising in the later Middle Ages: obligations, insolubles and consequences, and treats this field first time in such a unified manner. The articles on obligations look at the role of logical consistence in medieval disputational techniques. The articles on insolubles concentrate on medieval solutions of the Liar paradox.

The book also gives a systemic account of how medieval authors described the logical content of an inference, and how they thought that the validity of an inference could be guaranteed."--Jacket.
