 In light of the high status of demonstration, Ibn Rushd considered it with great care in his commentaries. He devoted a compendium, a paraphrase and a long commentary to the Posterior Analytics—which he calls the Book of Demonstration (Kitāb al-Burhān)—and wrote separate treatises on various special issues. The long commentary is probably the most appropriate text for his positions on the components of demonstration, its types, and its role in producing scientific knowledge. That commentary is also the occasion for a critical and severe interaction with the two Islamic authorities in logic before him, al-Fārābī and Ibn Sīnā.
