Note 144 — Chapter VIII · FREETHOUGHT UNDER ISLAM1

The course of culture-evolution there broadly corresponds with that of the Saracen civilization in the East. In Spain the Moors came into contact with the Roman imperial polity, and at the same time with the different culture elements of Judaism and Christianity. To both of these faiths they gave complete toleration, thus strengthening their own in a way that no other policy could have availed to do. Whatever was left of Græco-Roman art, handicraft, and science, saving the arts of portraiture, they encouraged; and whatever of agricultural science remained from Carthaginian times they zealously adopted and improved. Like their fellow-Moslems in the East, they further learned all the science that the preserved literature of Greece could give them. The result was that under energetic and enlightened khalifs the Moorish civilization became the centre of light and knowledge as well as of material prosperity for medieval Europe. Whatever of science the world possessed was to be found in their schools; and thither in the tenth, eleventh, and twelfth centuries flocked students from the Christian States of western and northern Europe. It was in whole or in part from Saracen hands that the modern world received astronomy, chemistry, mathematics, medicine, botany, jurisprudence, and philosophy. They were, in fact, the revivers of civilization after the age of barbarian Christianity.144 And while the preservation of Greek science, lost from the hands of Christendom, would have been a notable service enough, the Arabs did much more. Alhazen (d. 1038) is said to have done the most original work in optics before Newton,145 and in the same century Arab medicine and chemistry made original advances.146
