Abstract :In this article, we examined how Alfarab approached to the subject of cate gorical syllogism within scope of his works entitled “Kitāb al-Kıyās al-Sağīr” and “Kitāb al-Kıyās”. Alfarab defined syllogism as Aristoteles did it, and after defining it, made analysing of that definition, and then explained each of the terms which composed the definition in that analysing. Categorical syllo gisms were the main syllogisms that Alfarab emphasised. Before him, Aris toteles also took up those syllogisms. He examined it in the Organon and did not mention the syllogisms composed of conditional propositions. Alfarab no ted that categorical syllogisms had to have same special conditions in terms of quality and quantity for giving conclusions of each figure of the categorical syllogisms, and exemplifid the moods giving conclusion in every figure.
Keywords : Inference, syllogism, categorical syllogism, figures of syllogism, rules of fi gure, first figure, second figure, third figure, fourth figure, moods of figure
