The Treatise on Logic (Arabic: Maqala Fi-Sinat Al-Mantiq) has been printed 17 times, including editions in Latin (1527), German (1805, 1822, 1833, 1828), French (1935), and English (1938), and in an abridged Hebrew form. The work illustrates the essentials of Aristotelian logic to be found in the teachings of the great Arabic Philosophers such as Avicenna and, above all, Al-Farabi, "the Second Master," the "First Master" being Aristotle. In his work devoted to the Treatise, Rémi Brague stresses the fact that Al-Farabi is the only Philosopher mentioned therein. This indicates a line of conduct for the reader, who must read the text keeping in mind Al-Farabi's works on logic. In the Hebrew versions, the Treatise is called The words of Logic which describes the bulk of the work. The author explains the technical meaning of the words used by logicians. The Treatise duly inventories the terms used by the logician and indicates what they refer to. The work proceeds rationally through a lexicon of philosophical terms to a summary of higher philosophical topics, in 14 chapters corresponding to Maimonides's birthdate of 14 Nissan. The number 14 recurs in many of Maimonides's works. Each chapter offers a cluster of associated notions. The meaning of the words is explained and illustrated with examples. At the end of each chapter, the author carefully draws up the list of words studied.
