"Surgery also owes fundamental progress to the Arabs. Their work served as a basis for the teaching of Faculties of Medecine until quite recently. In the eleventh century of our era, they knew the treatment of cataract by the lowering or the extraction of the crystalline; lithotrity; the treatment of hemorrhage by irrigations of cold water; the use of caustics; setons; and cauterization by fire. Anesthesia, of which the principal discovery is supposed to be modern, seems to have been known to them. As a matter of fact, they speak favourably of the use of tare before undertaking painful operations, so that the patient may be put to sleep until "loss of consciousness and feeling" supervenes.
"They had, likewise, implicit confidence in hygiene in medical treatment, and placed great reliance on the resources of Nature. Expectant medecine, which, at the present time, seems the last word of modern science, reasons exactly in the same way." (Dr. G. Le Bon, La Civilisation des Arabes.)
In the domain of ideas, the influence of the Moslems had perhaps still more valuable consequences. Jesus preached equality and fraternity, but Mohammad was lucky enough to realise both among the Believers during his lifetime.
It would be absurd to maintain that his direct example served to guide the French Revolution which was not inspired by much of his levelling works. Nevertheless, the first attempts of this enfranchisement of ideas and the organisation of modern society on a new basis—and of this there is ample proof—resulted logically from his doctrines. Honour is due to a Mussulman philosopher, Ibn Rushd, or Averroes, who lived in Spain from 1120 to 1198, for being the first to introduce freethought—not to be confused with atheism—into Europe.
Averroes opposed the pure deism of Islam to mythological pantheism and Christian anthromorphism, and his 'Commentaries of Aristotle,' although vividly coloured with Mussulman tints, impassioned all independent minds in medieval Europe. Averroism, born of this enthusiasm, may be justly considered not only the precursor of Reform, but also the father of modern Rationalism.
The influence exercised by Mussulman customs over those of Europe was equally healthful. The Arabs joined most chivalrous manners to extreme religious tolerance.
"It was among the Arabs of Spain that the knightly spirit arose, and which was afterwards appropriated by the warriors of the North, as if it was a quality inherent in Christian nations," declares the celebrated Spanish writer Blasco Ibanez, in his novel: Dans L'Ombre de la Cathédrale. (In the Shadow Of the Cathedral.)
In this connection, we can again quote Dr. Le Bon:
"Like Christian chivalry, which came later, Arab chivalry had a code of its own. No man was worthy to be a knight unless he possessed the following qualities: kindness, valour, amability, poetical talent, eloquence, bodily strength, skill in horsemanship, and cleverness in handling spear, sword and bow....
"In 1139, the Wali of Cordova having laid siege to Toledo, belonging to the Christians, Queen Berengaria, shut up in the city, sent him a herald to bid him take notice that it was unworthy of a brave, gallant and generous knight to attack a woman. The Arab general retired forthwith, asking as sole favour, to be allowed the honour of saluting the Queen....
