Al Farabi Syllogism

The philosopher Abu Nasr al-Farabi (c. 870-c. 950 CE) is a key Arabic intermediary figure. He knew Aristotle, and in particular Aristotle's logic, through Greek Neoplatonist interpretations translated into Arabic via Syriac and possibly Persian. For example, he revised a general description of Aristotle's logic by the 6th century Paul the Persian, and further influenced famous later philosophers and theologians writing in Arabic in the 11th to 12th centuries: Avicenna, Al-Ghazali, Avempace and Averroes. Averroes' reports on Farabi were subsequently transmitted to the West in Latin translation. This book is an abridgement of Aristotle's Prior Analytics, rather than a commentary on successive passages. In it Farabi discusses Aristotle's invention, the syllogism, and aims to codify the deductively valid arguments in all disciplines. He describes Aristotle's categorical syllogisms in detail; these are syllogisms with premises such as 'Every A is a B' and 'No A is a B'. He adds a discussion of how categorical syllogisms can codify arguments by induction from known examples or by analogy, and also some kinds of theological argument from perceived facts to conclusions lying beyond perception. He also describes post-Aristotelian hypothetical syllogisms, which draw conclusions from premises such as 'If P then Q' and 'Either P or Q'. His treatment of categorical syllogisms is one of the first to recognise logically productive pairs of premises by using 'conditions of productivity', a device that had appeared in the Greek Philoponus in 6th century Alexandria.

This pioneer study of Aristotle's theory of deduction in early medieval Islam provides invaluable first-hand information on both the classical and the Islamic dimensions of an important chapter in the history of medieval Islamic philosophy.

Provides the first complete English translation of a central text in the Islamic philosophical tradition, with meticulously researched commentary and interpretation.

Alfarabi was among the first to explore the tensions between the philosophy of classical Greece and that of Islam, as well as of religion generally. His writings, extraordinary in their breadth and deep learning, have had a profound impact on Islamic and Jewish philosophy. This volume presents four of Alfarabi's most important texts, making his political thought available to classicists, medievalists, and scholars of religion and Byzantine and Middle Eastern studies. In a clear prose translation by Charles E. Butterworth, these treatises provide a valuable introduction to the teachings of Alfarabi and to the development of Islamic political philosophy. All of these texts are based on new Arabic editions. Two—The Book of Religion and Harmonization of the Two Opinions of the Two Sages, Plato the Divine and Aristotle—appear in English for the first time. The translations of the other two works—Selected Aphorisms and chapter five of the Enumeration of the Sciences—differ markedly from those previously known to English-language readers. Butterworth situates each essay in its historical, literary, and philosophical context. His notes help the reader follow Alfarabi's text and identify persons, places, and events. English-Arabic and Arabic-English glossaries of terms further assist the reader.

During the years 800-1200 A.D., Arabic scholars studied many of the works of Greek philosophy, and recorded their interpretations. Significant Arabic interpretations of Aristotle's Prior Analytics, the key work of his logical Organon, however, have remained largely unavailable in the West. The recent discovery of several Arabic manuscripts in Istanbul revealed the "Short Commentary on Prior Analytics" by the medieval Arabic philosopher al-Farabi. Nicholas Rescher here presents the first translation of this work in English, and supplements this with an informative introduction and numerous explanatory footnotes.
