Stoic Logic - Benson Mates

. .

Résumé :
Stoic Logic by Benson Mates is a groundbreaking study that reconstructs the logical system of the early Stoic philosophers, particularly Zeno, Cleanthes, and Chrysippus. Long overshadowed by Aristotelian syllogistic, Stoic logic was in fact a distinct and highly sophisticated propositional system. Mates demonstrates how the Stoics developed truth-functional accounts of logical connectives, distinguished arguments from conditionals, and built a calculus of inference rules from five basic undemonstrated forms. He also provides a clearer account of the much-debated Diodorean implication, explains the Stoic principle of conditionalization in relation to modern deduction theorems, and investigates the school's claim that their logic was complete.

Drawing on fragments preserved in Sextus Empiricus, Diogenes Laertius, Galen, and others, Mates offers a rigorous yet accessible reconstruction that has reshaped scholarly understanding of ancient logic. The book includes new translations of key fragments and a glossary of technical terms, making it an indispensable resource for both philosophers and classicists. By carefully comparing Stoic theories with modern semantics and propositional logic, Mates reveals how much the Stoics anticipated later developments in logic and philosophy of language. Stoic Logic remains a foundational text for anyone interested in the history of logic, Hellenistic philosophy, or the conceptual roots of modern analytic thought.
