How did Aristotelian and Stoic logic become combined in later ancient commentaries?

In the ancient world, Aristotelian and Stoic logic were initially viewed as distinct and often incompatible traditions, with Aristotelians focusing on term logic and scientific demonstration, while the Stoics emphasized propositional logic and disputation.12

However, by the late 1st century BCE, an eclectic movement began to bridge these differences, weakening the hostilities between the two schools. This shift led to the integration of both traditions within later ancient commentaries and handbooks designed for general education.12

This synthesis was further solidified by the scholarly efforts of later commentators. For instance, while Aristotelian logic remained the primary framework for formal study, the works of later philosophers—such as Alexander of Aphrodisias, Porphyry, and Boethius—helped consolidate and transmit these combined logical doctrines. By the time of the late antique period, these commentaries had effectively merged elements of both systems, establishing a unified approach to logic that would dominate Western philosophical training for centuries.34567
