Al-Abharī’s Isagoge is an introductory primer in logic which has received numerous commentaries, each geared towards students of various levels of familiarity with this instrumental science. Al-Fanārī’s advanced commentary on the Isagoge, called al-Fawāʾid al-Fanāriyya, has confounded students of logic for centuries due to its terse and dense style as well as the presumption that the reader knows well the science of disputation along with the subtle interpretive disagreements discussed in other texts and commentaries. Sājaqlīzādah’s primer on disputation entitled al-Waladiyya, (...) written nearly 300 years after al-Fanārī’s commentary, provides useful examples of the possible claims, objections, and defenses available to one making scholarly claims in the form of definitions, classifications, and propositional assents or syllogistic reasoning. In this article, I explore several instances of al-Fanārī’s use of the terms and methods of disputation in order to defend definitions or classifications found al-Abharī’s Isagoge. I aim to identify the specific disputational moves used by al-Fanārī, drawing from those described by Sājaqlīzādah. In doing so, I demonstrate that this important advanced commentary on a popular logic primer is best understood through the lens of disputation. I also argue that Sājaqlīzādah’s suggested methods of making claims, objections, and defenses can be transposed in whole or in part from one category of claim—definitions, classifications, assents—to another, indicating a greater complexity of disputational possibilities than his introductory handbook provides.
