logic
Also known as: Ars vetus, Old Logic

Quick Summary

The term "Logica vetus" refers to the "Old Logic" of medieval Europe, primarily consisting of the translations and commentaries of Aristotle's works by Boethius and Porphyry's Isagoge*. These texts were the main sources of logical knowledge in Europe until the 12th century, when the "New Logic" (Logica nova*), comprising further Aristotelian works and commentaries, became available. This marked a significant period in the history of logic, laying the groundwork for subsequent developments in medieval philosophical thought.12
