Hardcover. Zustand: NEAR FINE. cxxxiv, 532 (Arabic text); 539-1042 (English trans.). Complete in two volumes. Large 8vo's. Sewn bindings in black cloth-effect paper over boards with gilt stamped lettering. Some trivial shelfwear to the covers, both volumes entirely clean and sharp otherwise with tight bindings. Al-Farabi (d. 950 A.D.), arguably the most original and influential Muslim philosopher of the Middle Ages, wrote on subjects as diverse as music, medicine, and political theory, as well as logic, language and grammar, religion and metaphysics. The present work compares the Arabic terminology of Al-Farabi with that of his predecessors, by using their own sets of definitions. An English translation is also provided in a separate volume. Wherever possible, Greek parallel terminology is provided, together with the Hebrew and Latin terminologies used in the mediaeval translations of Al-Farabi's works. The work's two volumes include detailed indices, a detailed bibliography of the philosopher, and an interpretative essay.
