A scholarly edition of a classic textbook on logic Najm al-Din al-Katibi's al-Risalah al-Shamsiyyah is a scholarly edition and translation of The Rules of Logic, with 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 madrasah students from the early eighth/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.
