Abstract

Najm al-Din al-Katibi's al-Risalah al-Shamsiyyah is a scholarly edition and translation of The Canons of Logic, with additional commentary and notes. Composed by Najm al-Din al-Katibi, a scholar of the Shafi'i school of law, al-Risalah al-Shamsiyyah is the most widely read introduction to logic in the Arabic-speaking world. It has probably enjoyed a longer shelf-life than any other logic textbook ever written, having been in use by madrasa students from the early fourteenth century up until the present day. Building on the theories of Avicenna, al-Razi, and other pioneers of logic, al-Katibi discusses the many pitfalls of building arguments and setting out unambiguous claims in natural language. The enduring nature of the text is a testament to al-Katibi and his impact on concepts of formal discourse and argument.
