His Philosophy Criticized by Maimonides.

Greek physician and philosopher; born at Pergamus, Mysia, about 131; died about 200. Eclipsed by those of Aristotle, Galen's philosophical works were not held in high esteem by the Jews. Maimonides cites them only when they are in accordance with his own views, as, for instance, with regard to the impossibility of proving the eternity of matter ("Moreh Nebukim," ii. 15). Once he severely criticizes Galen, declaring that outside the field of medicine he is no authority ("Pirḳe Mosheh," xxv.), this stricture being called forth by the following utterance by Galen concerning the Mosaic conception of the omnipotence of God: "The difference between the Greek philosophers and Moses is this: In order that matter may be put in order it suffices for Moses that God should wish matter to be arranged. He believes that everything is possible with God, even the conversion of ashes into a horse or an ox; while we believe that there exist things with which, being naturally impossible, God does not interfere; He chooses only the best between possibilities" ("De Substantia Facultatis Naturæ," ed. Kuhn, iv. 760). Falaquera also shows slight respect for Galen's philosophy, affirming that in his later years the great physician wrote a work betraying ignorance of physics ("Mebaḳḳesh," p. 33).

But if in the domain of philosophy Galen's authority was contested, he reigned supreme in the field of medicine. Maimonides himself helped largely to propagate Galen's medical works by publishing a summary of sixteen of them, which were, so to speak, canonized by the Alexandrian school and by the Arabs. Maimonides was followed by many other Jewish physicians who paraphrased or translated Galen's works from Arabic versions (chiefly made by Ḥunain ibn Isḥaḳ) and from the Latin. These paraphrases and translations, the greater part of which are still extant in manuscript in various European libraries, are as follows:

("Ars Parva"), with a commentary by All ibn Ridwan, translated, according to Paris MS. No. 1114, by Samuel ibn Tibbon in 1199. The same work was translated anonymously, under the title , between 1197 and 1199.

, a paraphrase by Zerahiah ben Isaac ben Shealtiel of Rome (1277-94), in four books: (1) on the diversity of maladies; (2) on their causes; (3) on the variety of symptoms; and (4) on the causes of the symptoms.

, three treatises on the compounded medicaments according to their species, by the same.

, on the regimen of the epileptic boy.

("De Malitia Complexionis Diversæ"), by David ben Abraham Caslari (1280-1337).

In the twenty-sixth chapter of the "Healing of the Soul," by Joseph ibn Aknin of Barcelona (12th cent.), Galen's works are mentioned as forming a part of the regular school curriculum (Güdemann, "Das Jüdische Unterrichtswesen," etc., p. 100). He is also cited as an authority on ritual responsa; e.g., by Isaac b. Abraham Laṭif (13th cent.; see "Sammelband," i. 51, 53; Meḳiẓe Nirdamim, 1885).
