Oriental wisdom, Astrology and Cosmology delivered over [[11]]to Muslim thinkers material of many kinds, but the Form,—the formative principle,—came to them from the Greeks. In every case where it is not mere enumeration or chance concatenation that is taken in hand, but where an attempt is made to arrange the Manifold according to positive or logical points of view, we may conclude with all probability that Greek influences have been at work.
3. Greek Science.
1. Just as the commercial intercourse between India and China and Byzantium was conducted principally by the Persians, so in the remote West, as far even as France, the Syrians came forward as the agents of civilization. It was Syrians who brought wine, silk &c. to the West. But it was Syrians also who took Greek culture from Alexandria and Antioch, spreading it eastward and propagating it in the schools of Edessa and Nisibis, Harran and Gondeshapur. Syria was the true neutral ground, where for centuries the two world-powers, the Roman and the Persian, came in contact with one another, either as friends or as foes. In such circumstances, the Christian Syrians played a part similar to the one which in later days fell to the share of the Jews.
2. The Muslim conquerors found the Christian church split up into three main divisions,—to say nothing of many sects. The Monophysite church, alongside of the Orthodox State-church, preponderated in Syria proper, and the Nestorian church in Persia. The difference between the doctrinal systems of these churches was perhaps not without importance for the development of Muslim Dogmatics. According [[12]]to the teaching of the Monophysites, God and Man were united in one nature in Christ, whereas the Orthodox, and in a still more pronounced manner the Nestorians, discriminated between a Divine nature and a human nature in him. Now nature means, above everything, energy or operative principle. The question, accordingly, which is at issue, is whether the Divine, and the human Willing and Acting are one and the same in Christ or different. The Monophysites, from speculative and religious motives, gave prominence to the Unity in Christ their God, at the expense of the human element: The Nestorians, on the other hand, emphasized, in contrast with the Divine element, all that is specially characteristic of human Being, Willing and Acting. The latter view, however, favoured by political circumstances and conditions of culture, offers freer play to philosophical speculations on the world and on life. In point of fact the Nestorians did most for the cultivation of Greek Science.
3. Syriac was the language both of the Western and of the Eastern or Persian Church; but Greek was also taught along with it in the Cloister schools. Rasain and Kinnesrin must be mentioned as being centres of culture in the Western or Monophysite Church. Of more importance, at the outset at least, was the school of Edessa, inasmuch as the dialect of Edessa had risen to the position of the literary language; but in the year 489 the school there was closed because of the Nestorian views held by its teachers. It was then re-opened in Nisibis, and, being patronized by the Sasanids on political grounds, it disseminated Nestorian belief and Greek knowledge throughout Persia. [[13]]
Instruction in these schools had a pre-eminently Biblical and ecclesiastical character, and was arranged to meet the needs of the Church. However, physicians or coming students of medicine also took part in it. The circumstance that they frequently belonged to the ecclesiastical order does not do away with the distinction between theological study and the pursuit of secular knowledge. It is true that according to the Syro-Roman code, Teachers (learned Priests) and Physicians were entitled in common to exemption from taxation and to other privileges; but the very fact that priests were regarded as healers of the soul, while physicians had merely to patch up the body, seemed to justify the precedence accorded to the former. Medicine always remained a secular matter; and, by the regulations of the School of Nisibis (from the year 590), the Holy Scriptures were not to be read in the same room with books that dealt with worldly callings.
In medical circles the works of Hippocrates, Galen and Aristotle were highly prized; but in the cloisters Philosophy was understood to be first of all the contemplative life of the ascetic, and “the one thing needful” was the only thing cared for.
4. The Mesopotamian city of Harran, in the neighbourhood of Edessa, takes a place of its own. In this city, especially when it began to flourish again after the Arab conquest, ancient Semitic paganism comes into association with mathematical and astronomical studies and Neo-Pythagorean and Neo-Platonic speculation. The Harranaeans or Sabaeans, as they were called in the 9th and 10th centuries, traced their mystic lore back to Hermes Trismegistus, Agathodaemon, Uranius and others. Numerous pseudepigraphs [[14]]of the later Hellenism were adopted by them in good faith, and some perhaps were forged in their own circle. A few of them became active as translators and learned authors, and many kept up a brisk scientific intercourse with Persian and Arab scholars from the 8th to the 10th century.
5. In Persia, at Gondeshapur, we find an Institution for philosophical and medical studies established by Khosrau Anosharwan (521–579). Its teachers were principally Nestorian Christians; but Khosrau, who had an inclination for secular culture, extended his toleration to Monophysites as well as to Nestorians. At that time, just as was the case later at the court of the Caliphs, Christian Syrians were held in special honour as medical men.
