 Arabic logic begins in the middle of the eighth century. As with logic in the Latin tradition, it has its foundation in Ancient Greek logic, primarily in Aristotelian logic and syllogistics. The Syriac Christians adopted a teaching tradition in logic that included Porphyry’s Isagoge in addition to Aristotle’s Categories, De interpretatione and the first seven chapters of the Prior Analytics. This teaching tradition was adopted and spread through the Arab conquest. During the Abbasid Caliphate (750–1258), there was a continuous and growing interest in philosophy and logic. It is this time period that is often referred to as the ‘Golden Age’ of Arabic philosophy and logic.
