This translation of Albert of Saxony’s Twenty-five Disputed Questions on Logic brings to English readers an important fourteenth-century logician’s contribution to the analytic core issues in philosophy. Many of these issues are still actively discussed today. Albert treats issues such as the nature and scope of logic; the meaning and reference of terms; self-reference; logical difficulties with possessive, non-designating, and fictitious terms; mental terms and relative pronouns; logical problems with propositions, such as quantity, truth, falsity, conversion, and verification; the scope of denials and modal notions; Aristotle’s category theory; and the existence of universals. The book is intended to appeal to all those who are interested in the late medieval contribution to those discussions.


Albert of Saxony was one of the great logicians of the Middle Ages, on a par with William Ockham and John Buridan. The Twenty-Five Disputed Questions on Logic treat of central issues in logic, both then and now, such as the nature of meaning, of universals, of truth, and of tense and modality; and the quality and quantity of propositions, the role of negation, and the relations of contradiction and equivalence between them. Dr. Fitzgerald has studied Albert’s work extensively, and previously edited the Twenty-Five Disputed Questions from the original manuscripts. This translation makes available for the first time in English this careful and exemplary examination of logical notions by an outstanding medieval thinker.
